ANOTHER ONE!

I couldn't be more excited that CityWeather managed to invest and get a new and improved weather station. We now have a 5 Way Weather Meter (Station) (left picture) from Efston Science in Toronto. We also still have our original weather station, although it does not look like our new one. We currently use both. Both stations are portable, however the new one that we have needs to be screwed in every time, so that one will only be transported when I do my weather data. Keeping in mind, we still thank CityNews.ca for allowing us to receive access to CityNews Eleven Weather Stations. Although, CityWeather's stations are property of CityWeather and are not uploaded through Environment Canada.

I am hoping that we will eventually advance further and get a Professional Wireless Weather Station with PC Hookup. That one sounds neat. It is a station that is connected to sensors and will also allow us to upload data to a PC and track records.

The problem with the weather stations we CURRENTLY have is the fact that it does not contain a barometer. All in all I am glad that we received a better and new station. We will still use both stations. I can't wait to take this out on data.

On Another Note... It was dry in July be even drier in August around the GTA. At Pearson Airport only a scant 19.4 mm of rain fell for the entire month. August is normally the wettest month of the year with rainfall averaging 79.6 mm. July was also drier than normal in Toronto with just 47.4 mm. Looking at our weather station data it continued to be not very crop friendly in Newmarket. Only 4.6 mm of rain hit the gauge there. Here's what we recorded at the other stations:

Mississauga: 13.5 mm

Scarborough: 21.3 mm

Oakville: 41.2 mm

Ajax: 22.6 mm

Thornhill: N/A (rain guage problem)

Vaughn: 24.9 mm

North York: 14.7 mm

Brampton: 4.3 mm

Caledon: 14.5 mm

WHAT WENT ON TODAY?!

I checked my emails today. Another 20 or so of them asking the same question... what went on today? I thought to myself "Why? What was so different? And where?" I realized then they were Toronto-based. And Ontario-based too. Actually, I wasn't too surprised with the temps, nor the sky conditions, but the air quality is what really surprised me. I tell you why below. Then I'll explain what went on with the weather and give you a timeline...or so.

The smog. This morning I was up around 7AM and got ready for work. I started today at around 10AM. (On different days I start at different times; sometimes 4AM and sometimes 6PM...in case you were wondering. And I deliver (and broadcast) the weather). I usually also give the "Smog Readings" and record them and today I'll use Toronto as a prime example. This morning around 10:02AM the smog was at 42 (Moderate). It hovered around that index until 12PM. At 12 I checked the smog and the AQI: 7 (Very Good) and not one index in Ontario went above 16. So what happened? Well, didn't most of the forecasters predict a good Air quality today? This was mainly because of the heat and humidex being so low. When heat is not as high, and there is not much mugginess in the air, the smog decreases.

The sky. It was rainy, cloudy and so in the morning then cleared up in the afternoon. I predicted partly cloudy skies and sunny in the afternoon. It was because the radar imagery managed to clear up by 12. In addition to that, the barometric pressure was on the rise. When the pressure is on the rise, then the sky becomes clearer: the higher the pressure, the better the sky condition. Click here for a detailed picture of a barometer to see what I mean.

The temperature. Drastic change from yesterday. Yesterday it was 33 C feeling like 44C, but today it returned to normal conditions. Don't worry...it wasn't a heat wave, nor was it breaking records. We just reached previous records, but did not surpass it.

Heat Wave: A heat wave is only considered a "heat wave" when temperatures exceed 32C for three days in a row.

The wind and humdity. Can't complain...it was normal. Right?

I'll have your long weekend forecast for you tomorrow. Enjoy the warm weather.

If you have a weather question, please email me at (city.weather@yahoo.ca).

SHOCKING AUGUST

It's been a shocking August for Toronto and I'll tell you why below, but first earlier today I asked you to please send me emails of your city's highs for today. You came through. By 2 pm, I was flooded with over 100 emails, seriously. My inbox said "You have 137 New Messages"...and that was just by 2. What I decided to do was to take the majority cities of the emails that we received. Throughout the course of the week I may post more. My main focus though is on Toronto for only one main reason: it's too warm.

Here are a couple of cities:

Calgary: 24

Toronto: 34

Ottawa: 20

Winnipeg: 22

Montreal: 28

Iqualuit: 8

New York: 33

Glens Falls: 34

Yonkers: 30


But now I will let you know about Toronto (GTA) and August. This may come as a shocker to you. One of the driest summer's on record will stretch into September. There's no significant rain in sight over the next 7 to 10 days. Most areas around the GTA have seen only about 20 mm of rain so far this month. An average August gets about 4 times that much rain. Areas to the north in the agricultural belt are really feeling the drought. Crops are hurting. Our Newmarket weather station has only recorded 5 mm of rain all month. That's coming off of a July where only 9 mm of rain fell in the area. That's only about 1/10th the amount of rain the area needs for good crop growth. It could be a pricey Halloween for pumpkins. (Info Courtesy: CityNews.ca)

Although the smog will stayeth away. It's headed on a trip away from Toronto. I'll have more information on the smog's departure early tomorrow, followed by a blog later on tomorrow night. Tomorrow I need to wake up early, so I can do more research. But by the time 9am tomorrow, I'll have the smog info for you.

Once again, thanks for your emails. If you want much more information on August's shocking weather, please email me city.weather@yahoo.ca and let me know you need more. I'll be glad to send it to you.

What is a "Slow Day"?

I get emails asking me what the weather is like, what are "weather makers", etc, but I received this one email that caught my eye.

Chris,

I was just wondering for meteorologists and weather specialists, what does it mean to have a "slow day". People in the TSX have slow days or in the news, especially in sales, but I never hear about weather. Also, if "slow days" exsits, what do you do then?

Marianne

There is no such thing as a "slow day" in weather. Meteorologists and weather specialists are working 24/7. If you ever go into an Environment Canada building, you will see not one person sitting and doing nothing. The building may not be open 24/7, but people are there. They are tracking incoming storms, or even tracking storms that pass and see where they are headed next. With the radar systems, satellite imagery to creating the weather graphics for The Weather Network and updating their computers, there is always someone doing something.

Weather is considered an inexact science,which means that you cannot predict the weather once and leave it be for 24 hours hoping that it will not change. The saying "moodswings like the weather" comes from weather being inexact. The weather is always changing. Whether it'd be changing each hour or each second, it's changing. When people say "oh, look, that weather guy was wrong" it gets under my skin. Not because (s)he was wrong, but because most people do not understand that weather can never be 100% correct.

I have to admit though, when there is no change in weather within an hour, I get pretty bored and consider that a "slow weather change" or a "slow hour". And that's why I'm writing this blog now...

On one last note...CityWeather's producers have developed a CityWeather Back to School Forecast Blog to save me time. The address is www.citybts.blogspot.com .

WEATHER STATION: A QUESTION FROM A VIEWER

Brian asked me a question:

I was wondering who actually makes the weather station equipment you guys are using?

Brian, please note that CityWeather is not the CityNews. To access CityNews, go to www.citynews.ca .

However, the weather stations that CityWeather uses to keep data and track the weather, are provided by CityWeather itself. Environment Canada and CityNews has several weather stations across the G.T.A., such as Pearson Airport, Oakville, etc so we have weather stations that are not in that area. We also have one weather station for children/youth to track and see at certain times and that certain station was provided by Indigo Books.

Hope this helps...

Feel free to leave more comments or email city.weather@yahoo.ca

Next week I'll provide the BACK TO SCHOOL forecast.

Weekend Outlook for Toronto

Saturday still looks a little shaking with a cold front moving through but the weekend as a whole should be fairly nice. The cold front could set off a few spotty morning to midday showers. I stress spotty. By the afternoon the sky will slowly clear. The winds will shift direction and the humidity will disappear by about 2 or 3 PM.

For Sunday a ridge of high pressure is going to move in from the northwest. It could be a little breezy overnight but that wind will die by the afternoon. I'm calling for a high of 25C on Sunday under a partly to mainly sunny sky. The sun will stretch into the last week of summer break with temperatures climbing to as high as 30C by Tuesday.

Enjoy your weekend,

Chris

AUGUST: THE WETTEST OR THE DRYEST?

Quick Note: I have deleted my previous blog of the 7 day forecast because it changed all up. I will, however, update you on the week as it progresses.

Onto this note, is August the wettest or dryest month of the year? Generally, August is usually the wettest month of the year with precipitation reaching up to 80 mm. THIS YEAR: That has changed! This year, August is not yet classified as the driest of the year, but so far is has been quite dry. So far, to date, Toronto has received LESS THAN 10 mm of precipitation. Wow!!

That is a drastic change, especially for meteorologists /specialists. I'll update you tomorrow on the 7 day. Friday will be the weekend forecast.

CONTACTING THE CARIBBEAN

Most people have relatives or friends who are affected by the Caribbean.

To find out to see if they are safe, you need to contact the Ministry of Foreign Affairs. The number and the website can be found under the "Ministry of Foreign Affairs" link found in the WeatherWeb section on the left hand side.

To donate to Jamaican's affected by the storm, you need to contact the Jamaican Canadian Association. The website can be found under the "Jamaican Canadian Association" link found in the WeatherWeb section on the left hand side.

To see the blog that I wrote earlier outlining Hurricane Dean, click here.

HURRICANE DEAN

Story below copyright and courtesy of Citynews.ca


Hurricane Dean made landfall in Mexico Tuesday as a rare Category Five hurricane but subsequently weakened to a Category Three, as thousands of residents and tourists scrambled for shelter.

The storm picked up strength after sweeping past Jamaica and the Cayman Islands Monday, and was packing winds of about 270km/h as it moved west across the Yucatan peninsula. However it lost some intensity as it moved over land. Still, Mayan ruins and oil facilities were considered at risk, and state oil company Petroleos Mexicanos opted to shut down production Monday on its offshore rigs.

Dean has so far been blamed for 12 deaths across the Caribbean, and though it wasn't expected to strike the resort area of Cancun directly vacationers fled Mayan Riviera beaches to be on the safe side.

Mexican President Felipe Calderon, meeting with Canadian Prime Minister Stephen Harper and U.S. President George Bush in Quebec opted to cut his trip short on account of the potential devastation to parts of his country.

Dean was on course for central Mexico next, and could bring rains and heavy winds to Texas in the U.S. A hurricane warning was in effect from Cancun to Belize, and in Belize City three hospitals were evacuated. Patients were moved inland to the capital of Belmopan, founded after hurricane Hattie destroyed Belize City in 1961. Belize City's Mayor Zenaida Moya urged residents to leave the city saying that its shelters weren't strong enough to protect against the wrath of a Category Five storm.

Tourists have been leaving the area by the planeload and officials suggest 50,000 have left the Yucatan over the past three days.

The worst storm to hit Latin America remains 1998's Hurricane Mitch, which killed almost 11,000 people and left more than 8,000 missing.

If you're worried about friends and family who are stranded in the Caribbean you can call the Ministry of Foreign Affairs for more information. The number there is 1-800-267-8376.

To send your donations to Jamaican's affected by the storm, visit the Jamaican Canadian Association Website.

----------------------

As I write this blog (1:30 pm on Tuesday), Dean is at a Category 2 with winds of 167 km/h. Those winds will gust to 222 km/h. Dean is 1242 km north-west of Miami, FL.

4AM WAKE UP CALLS

I just wanted to let fans know...

All of next week (and possibly the continuing week) I need to rise and shine at 4:00AM. That's what I've been told and that's what I need to do. Got any tips to help me wake up? Send them by email!!


And on one last note:Did you know that early morning weather is NOT the same as morning weather? Why would someone tell you that...isn't it a given fact? Today I got to experience it. When I headed to BT's Viewer Appreciation Day (www.citytv.com/bt or http://www.citynews.ca/) I had to rise and shine at 4:00am....well it started at 6am! It was great......loved every bit. But to the point, 4:00am weather (and even traffic) is completely different compared to the 6;00-9:00 am and even afternoon weather. It was more nippy but still comfortable conditions. I actually liked waking at 4:00am

WEATHER: A Smash Hit This Time of Year?



Earlier I asked you to send me reasons why you think weather is a smash hit...you know, like the Phantom of the Opera was a smash hit musical. Man, did we get answers.


N.B.: This blog you will find a lot of links. Please click on them for more information.



So, why is Weather such a smash hit? The end of summer-beginning of fall season is a popular time for tons of events to take place.





First, here are YOUR reasons:
  • Last-minute vacations
  • cottage country trips
  • getting into the swimming pools before closing
  • the events

So many reasons. Last-minute vacations are extremly popular and why? Well, don't we want heat?

Cottage country trips: do you want it to rain out?/

Swimming pools: Toronto's swimming pools close on Labour Day.

The popular reason: events. Too many to mention.

First off, let's start with the BreakfastTelevision Viewer Appreciation Day [Toronto] taking place from 6:00-9:00am.(wake up early). It is located on 299 Queen St. West [CHUMCity Building]. To watch the "behind the scenes" prep for BT day, click here.

Then, it's also the opening day of the C.N.E. (Canadian National Exhibition). Of course, we also have those [my appologies to the kids for saying this] Back to School shopping (supported by Staples, Business Depot).

And with the shopping comes September 4th....."BACK TO IT" day -- for all of us,

But before that, it's the last minute Labour Day (and family) BBQ's. Good times....

But remember, there is always next summer. Oh! and also nice weather too!

Now, I know there are sooo much more events that WEATHER plays a HUGE part in, but these are only a few.

To participate in our "Weather: A Smash Hit" poll, click here.

Enjoy the events....

Back!

Back to blogging and back to tracking!! I'm back from my holidays. I headed down to New York for a wedding on Saturday...it was so beautiful that day. The weather and the wedding...well the wedding was extravagant! We drove down there and Friday morning (and all day), freezing. A rain storm continued and it brought the cold. We left Friday 12:30 am from Toronto (warm) to cold N.Y.C. Saturday and on was grogious though, my favourite was the wedding. From Saturday to Monday we went visiting and on Monday we shopped at the Palisades Center (USA) ... four levels of huge stores. It was a great trip.....again, the wedding was my favourite.

Anyways, to the weather. Tomorrow is calling for thunderstorms, but Friday is my hope of nice weather. I'm heading down to the CHUMCity Building (299 Queen Street West, Toronto) for BT's Viewer Appreciation Day. It's taking place from 6:00am to 9:00am. Lots of great things I hear......especially the food: burgers, cereal and prizes and give-a-ways. Can't wait. I predict lows of 15C and highs of 23C with partly cloudy skies...so it's not too bad. The morning seems nice.

I HATE TO SAY WHAT I'M GOING TO SAY, but I've been instructed (by the bosses) to remind you that FALL IS COMING and I MUST write a blog on it....but I'm regretting it and don't know what to say. There are too many things to talk about, so we'll have a blog devoted to Fall! Everytime the new season arrives, we will have a blog on it for the month of the beginning of the season. This one will be called CityFALL. This should be out for the beginning of September.

Also, we say farewell to CityHEAT blog on Monday. It's been a pleasure with working with the CityHEAT blog producer (Mike) but he'll be blogging for CityFALL.


A lot I needed to catch up on....but I did it! and as for those emails, I'll get to them.

WEATHER STATIONS & JULY RAIN TOTALS


Truth be told, I've been getting a lot of emails and I appologize for the lack of response. I think I'll be working this vacation answering emails...or writing ways I can, anyways. I promise though, I will get those emails answered before the end of Summer (meaning beginning of September).
I've actually been getting quite a dozen emails asking this question: What are weather stations? When are they used? What are they for? How is it used... etc. Today is the day I answer that question.
To the left, is an example of just one of the various types of weather stations, although all consist of the same tools.
Weather Stations are just like tracking the weather, only from different places. Each station transmits the weather back onto the computer to track storms, temps and help [us] track weather and transmit it back to you, for an EXACT look at the weather in YOUR area. It makes tracking weather easier.
To get a complete in-depth tour of what weather stations consist of, click HERE. This link will also be posted on our "CityWeather Links" column found on the left-hand side of the blog. This will tell you each of the instruments used in a weather station.
JULY RAIN TOTALS (for Toronto):
From the various CityNews Weather Stations across the G.T.A., [they] were able to collect July's rain totals for Toronto for various parts of the city.
Again, truth be told, July was a dry month and you may be surprised at the results.
RESULTS*:
Pearson Int'l Airport: 47.4mm
The average amount of rain at Pearson is 74.4 mm, respectably.
Caledon: 8mm
Newmarket: 9mm
Scarborough: 51mm
Ajax: 16mm
Oakville: 20mm
Mississauga: 31mm
Vaughan: 33mm
North York: 43mm
Brampton: 36mm
Thornhill: Did not record rain averages accurately this month.
*All measurements are calculated at a respectable average with courtesy of CityNews (http://www.citynews.ca/).
Keep in mind that I am headed on holidays Friday, so I will only be blogging tomorrow, and returning Wednesday. You are more than welcome to continue the emails.

Notice the "Links"?

Do you notice the CityWeather Links section on the left hand side? Generally each time I find a new link I'll update it (or for sure once every week). They actually have interesting links so check them out. You never know, you may enjoy them. And it makes blogging easier for me!

I'll have a weather blog later today so check back...just wanted to check oout the Links.

BEAUTIFUL LONG WEEKEND

Could we ask for a better long weekend? The weather was superb...but of course the Tuesday had to rain. Friday was nice...peaceful, and relaxing. Didn't go to bed until around 3:00am Saturday morning and woke at 9:30 am, no idea why. Saturday was peaceful. Of course, Saturday night had to be ruined at Yorkdale (Toronto). It's a great mall, don't get me wrong but it is sooooo busy. Sunday was also relaxing. Went to see my grandma (Mama) and mother .... nice BBQ. It was so nice--windy though. Monday I headed to work at my aunts and same for today. Well atleast Saturday and Sunday was peaceful with Monday of work.

But who cares about me...right?

Caribana Parade and the various events around Toronto went beautiful with the weather.

This week is looking good too.

There's no interesting weather to report in the forecast. But if you spot any, let me know right away through email. Please...

The radar imagery is also looking like it's clearing up so that's good.


Just a quick note.......I'll be off from Friday to Wednesday again. I will be back reporting on Thursday. But I'll still blog tomorrrow and Thursday.

If you have any weather links, click on CityWeather Links on the left side and enjoy!


Lot's of weather luck....

LONG WEEKEND OUTLOOK

For those of us here in Toronto (and Canada for that matter), Simcoe Day or Civic Day is a holiday. And the outlook is looking fantastic for Toronto!!

That scorching heat and humidity is getting swept out by a cold front, even though, it will still be warm on Saturday with the high around the upper twenties. The air quality will be good to low moderate and the UV index will be quite high, too. The wind direction changes from southerly to northerly, which will make it feel drier than usual, while the AQI will be better. Sunday will be similarly beautiful with just some late day cloudy periods and a high near 28C. A weakening low could bring in some early morning showers for the holiday Monday but it looks like it's going to clear by the afternoon. A huge change will be in the overnight lows. Expect the temperature to drop to a seasonally fresh 17C on Saturday and Sunday mornings so shut down the AC and throw open the windows to enjoy the fresh air.

[Cottage Country]: For those of you up in Cottage Country, it will be cooler in the mornings. With temps on Saturday [morning] hovering around 14C and Sunday to 11C. Afternoons, however, looking great. Keep an eye out for highs around 27C and lots of sun across central Ontario on Saturday and Sunday. Monday brings in cloud cover with a slight risk of morning showers. Highs, though at 28C. Personally, I have no complaints about the long weekend...and we need at least one day of rain after this heat--good time to read, relax and recouperate.

I'll be off on Monday, but blogging again on Tuesday. Wishing everyone a safe and happy long weekend. Get some rest...we all need it!

Chris - city.weather@yahoo.ca

BREAKING RECORDS

We broke a record during TORONTO's 3-day heat wave, believe it or not.

First off, on Tuesday we reached a high of 33.8C. The record was set in 1975 with a temperature of 36.1C. We did, however managed to exceed the 2006 reading of 33.7C. Wednesday's temperature was at 34C. The record was set for 36.7 in 1995, while the 2006 reading was at 36.6C. So, compared to the past few years, Wednesday was cool.

Thursday was the record that we broke. We reached a high of 35C. The new record was Thursday (2007) at 35C. The old record was actually set in 2006 at 34.3C. Congratulations Toronto!

Later tonight around 9:00 pm (EST), I will have your long weekend Civic Holiday forecast and how it plays out. So check back.

Email me with your scorchering summer stories at city.weather@yahoo.ca . I will post them sometime next week.


Keep cool!

HUMIDEX ANSWERS

Well, the egg cooking didn't quite work. In 20 minutes, just a part of it was partially cooked. If you try this experiment...never eat the egg! I'm still trying to manage to get videos posted...my blog host isn't cooperating, nor is Youtube.

Anywho, this morning's blog consisted of humidex and what it is. Well for a recap the formula is

Humidex = T + Td - 12

Where:

T = Temperature

Td = Dew Point

and earlier I asked you to try to calculate this humidex if the temperature is 33C and the dewpoint is 18C.

And my......did I get flooded with emails. 92% of the emails were correct answers. The other 8% were not. Most people used the easy method (H=T+Td-12) and some used the harder method (Humidex = T + 5/9 x (e - 10)).

Now, the people using the harder method did not receive the right answer, because they did not get all of the information. I did not gie you the "e" part (vapour pressure), which was my error. So, below is the calculations to the correct (easy) method.

See you tomorrow....

Chris - city.weather@yahoo.ca



Humidex:


H = T + Td - 12

H = (33) + (18) - 12

H = 39C.

39C is hot!!



"What is Humidex" blog entry

HUMIDEX? EGGS-PERIMENT AND STORM WATCH

What us humidex? Today's a perfect day to talk about it!

The humidex is a complex, made in Canada formula, that incorporates actual air temperature and relative humidity. It represents what the air feels like on our skin in relation to our body's ability to cool itself through the evaporation of sweat. The higher the combination of air temperature and relative humidity the harder it is for the body to cool itself. This combination makes us feel hotter under hot and humid conditions than under hot and dry conditions. This puts some weight behind the cliche, it's not the heat it's the humidity.

The actual formula looks like this:

Humidex = T + 5/9 x (e - 10)

where:

e = vapour pressure(6.112 x 10^(7.5 x T / (237.7 + T) x H / 100)

T = Air Temperature (Degrees Celsius)

H = Humidity (%)


If your brain hasn't exploded or you haven't passed out yet here's a rough but easy formula for calculating humidex that can get you in the ballpark:

Humidex = T + Td - 12

Where:

T = Temperature

Td = Dew Point

So if the temperature is 30C and the dew point is 25C The humidex would be approximately 43. That's hot!


Try to calulate today's humidex in Toronto. Temperatures right now are standing at 33C, the dew point is standing at 18C. Use the formula. You can email me the answer to city.weather@yahoo.ca and I'll also give you the answer later on my blog when I put the "egg heat test". That'll take place around 1:00pm when it's the hottest outside! I COMPLETED THE EGG HEAT TEST, BUT I AM TRYING TO FIGURE OUT HOW TO POST VIDEOS. STAY TUNED.

SUMMER HEAT WAVE (Link) & TOMORROW'S EXPERIMENT

I'm not going to lie to you...I'm brave and literally love all types of weather but today, I went out and made a U-Turn to come back in. Opened the door to find my bosses pointing their finger out the door for the "Street Weather Forecast".

Grrrrrrr.......hot.........sweaty.........ahhhhhh!

Getting to the point...today was HOT! CityWeather has developed a new blog that our Environmentalist blogs on, it's called CityHEAT. Click here to access the blog. This blog will give you and link you to various heat wave stories. Updated during heat waves, alerts and advisories. By the way...the site is www.city-heat.blogspot.com

Various occasions I will personally also update the blog. Many of the stories that I wish to speak of will also be found there. Check back often....as often as this blog gets checked.


Tomorrow, there is NO excuse for me to make a U-turn. I've been assigned an experiment--in the heat. I will be frying up eggs on the sidewalk. Watch for my video tomorrow evening (or Friday's blog). And tomorrow I hope the temp reaches 35C (or else it won't work as good). I call for a high of 30C. You'll want to check back to see how it goes.

Also, if you have any suggestions for beating the heat while I'm out there (or preferred attire), send them to me at city.weather@yahoo.ca (I've gotten rid of the V.R.).

BACK TO A HEAT ALERT~

I've returned early from my vacation so I could take another one later in the summer. It was so beautiful....the outdoors, wild, SUN, HEAT, pool---just gorgious. And now to the heat.

An extreme heat alert has been posted. I am currently doing some investigations as to the heat alert since I'm not that up to date.

I should have a blog later for you today or early tomorrow...also I'll have August's weather outlook.

My email is still on vacation so if you send me one, you will get an automatic vacation response, however I will respond to them when I check it...ignore the vacation response.
