The heat is on! Winnipeg hottest spot in country with 34C reading.. Heat wave to continue into early next week..
The heat wave has officially started in southern Manitoba with numerous localities hitting 32c or higher today. Hot spot honours went to Winnipeg with an afternoon maximum of 34.1C at YWG airport, and 34.5C at the Forks.. the hottest temperatures in Canada today. Humidex values touched 40C this afternoon as dewpoints rose to 20C in the city.. uncomfortable, but not as oppressive as the 24C dewpoints Winnipeg recorded on June 30th that resulted in peak humidex values of 44c. The hot weather will continue through the weekend into early next week with daytime highs of 32-35c likely through Tuesday. Luckily, humidity values will be somewhat tolerable over the next couple of days as some drier air from northern Manitoba works its way across the Interlake and northern RRV. Dewpoints on Sunday and Monday are forecast to drop into the mid teens in Winnipeg.. quite comfortable compared to the oppressive 22-25c dewpoints being recorded south of the border. By Tuesday however, the higher dewpoints will be spreading back into southern MB with humidex values likely reaching the low to mid 40s across the RRV. Current indications are that a cold front will push across southern MB Wednesday with showers and thunderstorms, followed by cooler and more comfortable conditions later in the week.

That storm southwest of Roseau MN is looking dangerous ( well defined hook echo).ReplyDelete
Storm trying to form south of Winnipeg!!
Bring on the storms for once! The storms make me love living here so much, but it's sure been a bummer this year where storms seem like a fantasy. Hopefully we'll get luckier when the cold front passes mid week. Perhaps 35C Tuesday? =)ReplyDelete
hey if you want/like CB+ move to Florida already!ReplyDelete
Looks like we'll get missed yet again with these storms off to our south. Give me a break how much longer is this curse gonna go on for? Were into the latter half of July and we haven't really gotten any real storm.ReplyDelete
Interesting story in the Free Press about a local pool company who will reimburse customers the cost of their pools if the temperature at YWG airport hits 34.5C or higher Monday. Manager took out an insurance policy back in March to cover the potential payouts. Will be interesting to see if YWG can hit that 34.5C mark Monday which would be a record for the day (currently 34.4C in 1967) Current data suggests temperature may just fall short.. 33-34c.. but it will be close.ReplyDelete
Yeah, I saw that article, Rob. Will be interesting indeed, likely a close call! The neat part is how the manager randomly picked a day in the summer (turned out to be July 18th) all the way back in March...who would have though it might actually come through!ReplyDelete
A forecast high of 37C on Tuesday.
That along with high dewpoints will make it a brutal day for sure!
It's bad enough with all this heat and humidity, But there is on some day's NO WIND!! Stale....ReplyDelete
Very heavy rain with those cells over over NW Minnesota last evening.. 3-4" of rain around Karlstad!ReplyDelete
I'm surprised no one here mentioned the great lightning display to the south of us last night. We were in St James around 10:30 and later in Lindenwoods and the show that was going on in the southern sky was absolutely remarkable!ReplyDelete
Th sky was continually lit up with hundreds of flashes of lightning. This went on nonstop for a very long time.
Thunderstorm in Iqaluit! I've never seen that before...ReplyDelete
Good thing the pool company has insurance....they could taken a soaking!ReplyDelete
I could've sworn I had seen a flash of lightning on CTV's webcam last night...ReplyDelete
The SPC has a moderate risk of severe weather for the Grand Forks/Fargo area. Really only defines an elevated tornado, high wind, and hail risk, though.
My weatheradio just went off on the haywood station turns out Environment Canada issued a severe thunderstorm watch for Killarney, Pilot Mound, and Manitou. This year Sucks! Come on already when are we going to get a Good Severe Thunderstorm! 2010 was better than this year for storms.ReplyDelete
Lightening twice in the same location, is not unusual, but two tornadoes in 18 hours?? Hannaford, Griggs county ND yesterday at 7pm and today at 3pm (now??)ReplyDelete
Hey Um Guys A thunderstorm just popped up South of us and could hit us in the next while. Look Up KTIV storm track four interactive on google. Great Radar!ReplyDelete
I Think that storm will now miss us as it is maintaining a west east direction sorry folks. Rob please let us know when we could get some big storms here! Why aren't we getting any here with the way the atmosphere is?ReplyDelete
Hey Mike M. quite your squawking and move to Florida already!!ReplyDelete
That convection south of Winnipeg never really had a chance. I saw it fire up west of town awhile back. It pulsed up for a bit but then quickly collapsed.ReplyDelete
It's obvious the best dynamics and lift are in North Dakota and Minnesota again. Check out the supercells in central/southern ND.
There will be more chances in the next week. Wednesday, at this point, could be a significant outbreak here in southern Manitoba.
Can't rule out nightly complexes firing up either as we are north of the strongest capping.
Winnipeg is too dry today for thunderstorms.. our dewpoint has dropped to 12C this afternoon with 30% humidity. Storms are occurring further south of us where there's better low level moisture to work with.
As Derek noted, we'll have to wait for the cold front to sweep through later this week for a better chance for us to see storms.. perhaps Wednesday. There's also a chance of some nocturnal storms Monday night/early Tuesday as another wave of warm air moves over us.
I would love to see a high of 35C tomorrow!ReplyDelete
For a record high and too see some people win a pool!!! YESSSSS!!!!!
hmmmm.....35.2 C tomorrow at the Winnipeg airport! That's my guess!!ReplyDelete
Okay I'll guess I'll move to florida, I'll think about it! I'll also shutup okay! see ya guys!ReplyDelete

Issued by Environment Canada at 4:31 AM CDT Monday 18 July 2011.
Humidex advisory issued for..
Steinbach - St. Adolphe - Dominion City - Vita - Richer
Morden - Winkler - Altona - Emerson - Morris
Killarney - Pilot Mound - Manitou
Melita - Boissevain - Turtle Mountain Provincial Park
Virden - Souris.
Temperatures across Southern Manitoba are expected to climb into the
low to mid thirties once again today. Additionally in southernmost
parts of the province, the humidity is expected to rise this
afternoon enough to push humidex values to 40 or higher. These high
humidex values will diminish somewhat tonight, but on Tuesday will
become widespread over most of Southern Manitoba as winds push the
higher humidity northward and temperatures remain hot.
This is an advisory that high humidex values are expected in these
Regions. Monitor weather conditions..Listen for updated statements.
Hey Rob - According to E.C.'s data on their web page for Averages & Extremes for this day, the MAX for today was 32.8°C in 1974 (1938-2008),ReplyDelete
Vice your 34.5°C in 1967.
Why this discrepancy ?
I enjoy your comments so keep them coming. If anonymous doesn't like them he doesn't need to be here and he should move to Florida.
My mistake.. the record high for today is indeed 34.4C, but it was recorded in 1923, not 1967, at the old St John's College climate station (1872-1938). The data that EC uses on their page is only from the YWG airport site (1938-present)
Still not convinced we're going to hit that 34.5C today.. we're running a little cooler than this time yesterday, and 850 temps are about the same as yesterday when we hit 33.5C. We'll see what happens..
I used to always get frustrated about missing out on storms. I've learned enough over the years to not worry about it too much any more.
We can and do get our share of big storms here in Manitoba, although the past few years have been pretty quiet overall.
It's only a matter of time before we get another stretch like 2005-2007.
The core of the heat is in extreme Southwestern Ontario.ReplyDelete
Harrow only went down to 26C this morning (humidex stayed 35C).
Windsor has already register a humidex of 39 at 10AM.
I'm glad I'm not the only one who gets frustrated when we miss storms all the time, like this year. Mike M I'm with ya buddy don't let anonymous posters stomp down your love for storms by telling you to stop complaining and move to Florida. I love my storms too and get frustrated when we’re constantly missed. This year that seems to be the story of this summer. I hope the rest of this summer can somewhat be redeemed. Our storm season is so short so there isn't a lot of time to enjoy these beautiful spectacles of nature (nature’s fireworks!). Sometimes I feel I live in the wrong part of the world and if I wanted to see storms all the time then maybe I should move somewhere where they do happen all the time but for now that isn't an option for me so I just hope that we can get as many as possible without destroying anybodies lives of course. Believe me I wouldn't want people’s lively hoods or safety to be compromised for the sake of getting weather I enjoy but this is weather and nobody is ever going to be pleased with what we get. Too hot, too cold, too wet, too dry, too windy, too many/not enough storms you just can't win :) I need to learn not to worry about an element I have no control over and also not let other people’s opinions urk me. Their attitudes can't control the weather either :)ReplyDelete
Rob that precipitation amount you posted at Karlstad, MN how did you find that?ReplyDelete
Adam.. I got that from NWS Grand Forks storm report page, as well as from their NEXRAD radar rainfall product. (click on my name for storm report link)ReplyDelete
I love the Discovery show Storm Chasers. There's a abbreviation they often use that I can't seem to figure out. "RP", I think it has something to do with inflow winds that are in front of a supercell. Anyone out there can help me out on this one?ReplyDelete
Not sure about RP..ReplyDelete
Do you mean RFD?
If so, that's the rear-flank downdraft.
Basically dry air wrapping around the back of the meso which is big for tornadogenesis.
Hey guys I'm back thanks for your encouraging words, Alright I don't know if you know but a storm system/ warm front cold front is entering Southern Manitoba look for a poss. of severe storms popping up tomorrow and on wednesday so stay tuned for more updates from me!ReplyDelete
By the Way do any of you guys have a weather alert radio they are great to have even though they can be annoying, if you don't you can buy them online or you can get them at walmarts in the states. The best are the midland brands, and first alert brands such as the WR 300 and WX 150 thats what I have.ReplyDelete
Just checked the GFA Nav Canada Model for prairies turns out that storm system looks to weaken by 06Z tomorrow which is 1am tuesday. Sorry no Storms to be seen quite yet. BOOO!ReplyDelete
There is a slight chance of a thunderstorm tomorrow morning but nothing more than that.ReplyDelete
Keep an eye on tomorrow night. Some of the models are showing enough mid level cooling moving in for some elevated convection.
Wednesday could be a big day in southern Manitoba. A strong front and shortwave moving through late in the afternoon should be enough to break the cap. Severe weather is definitely possible.
Looking a bit further ahead, Friday and Saturday do have some potential. Not worth saying much more at this time since it's so far out.
Alright derek thank you finally some good news for us. by the way what is A cap? is it like warm upper level temperatures that prevent storms from bubbling up?ReplyDelete
34C in Windsor with a dewpoint of 24C...ReplyDelete
Humidex of 45.
The Carman humidex record might be in danger considering Windsor should warm up to almost 40C on Thursday.
I just looked at the PASPC outlook and here is what they had said at 2:00 pm TONIGHT WE MAY SEE SOME NOCTURNAL CONVECTION AS A 25KT LLJ POKES UP TOWARDS SW MB THIS EVENING. CONVECTION FIRING OFF THE NORTHWESTERN PORTION OF AN UPPER RIDGE IN WESTERN NORTH DAKOTA OR EASTERN MONTANA FORECAST TO RIDE THE UPPER FLOW TOWARDS SW MB FIRST THIS EVENING THEN, PERHAPS, INTO THE RED RIVER VALLEY OVERNIGHT TONIGHT. Sorry If I took it off there website, it's just for your information. I Hope they are right.ReplyDelete
hey is anyone reading my comments please reply.ReplyDelete
Yes, a cap is a layer of warm air aloft that can act to suppress or inhibit convection.
New highest dewpoint in Canada in 2011... previous high I've seen this year was 25C on June 30 in Winnipeg.ReplyDelete
Harrow, Ontario currently has a dewpoint of 25.5C (air temperature is 31.3C).
Looks like the steamy air went a little further east.
Actually the 'steamiest' air is just off to our south and west. Once again we have high pressure over the western Hudson Bay region feeding down dry air. Its been a stable, persistent, drought pattern for NW Ontario into parts of Manitoba while areas further south and west received drenching rains (and also higher dewpoints from soil evaporation). Rob you jinxed us with that 'no rain for 6 months' comment.. haha just kidding.ReplyDelete
Having said that, winds have finally turned south again and that tropical air will ooze northwards. Given the dry topsoil conditions (and concrete surfaces in the city) we will likely not see the extreme dewpoints showing up in the dakotas right now.
Mike You might want to head a little west of Grand Forks for some of that weather your looking for.ReplyDelete
This was the last 2 days action in Hannaford, ND. 4 Tornado reports in 18 hours including 2 predicted on this blog. apologies for abusing NWS GFKS Storm Reports.

Close but no cigar!ReplyDelete
Looks like Winnipeg airport's temps will be falling short of that 34.5C mark today.. it's been as high as 33.2C this afternoon, but with some cirrus overhead and diminishing daytime heating.. looks like we won't get any higher. Sorry folks.. at least you have a nice pool to enjoy the heat with!
Too bad they didn't pick tomorrow.. 850 mb temps of 25C forecast to spread into southern MB (even higher temps of 25-30C forecast by the RGEM) so it's looking like we have a shot at 35-36C Tuesday afternoon. Early morning threat of thunderstorms as well with elevated convection riding on 850 mb jet with a good surge of low level moisture, then turning breezy hot and humid with dewpoints climbing into the 21-24C range giving humidex values around 45C by afternoon. A real steambath tomorrow.. stay cool!
Showers and thunderstorms still forecast for Wednesday, although timing of cold front may diminish threat of severe storms over RRV. Stay tuned..
EC is predicting a high of 39 for Windsor on Thursday! With the high dewpoints, think it might have a chance of beating the Canadian humidex record of 53?ReplyDelete
Windsor would need a dewpoint of 27C with that 39C to get a 53 humidex.. not likely at those temperatures. 39C seems a bit extreme given the high dewpoints, so I'm thinking they won't be that hot.. perhaps 35-36C instead. With dewpoints around 24-25C, that would give them humidex values around 47-48C. Bad enough :)ReplyDelete
Guys I was serious about the PASPC comment it came directly from environment canada in winnipeg. we could see some storms overnight have a look at their forecast i could prove you right on this one. Hey I also heard victoria beach was 37C at 4pm by listening to my weatheradio. CTV said Dauphin was the hotspot, but i think victoria beach was for today what do you think?ReplyDelete
I think you guys are right lets hope windsor doesn't break our record set in carman back in 2007 but if it does that would make windsor canadas all time hotspot. What more dissapointment is to come hey rob?ReplyDelete
Sorry I did not read the comment properly, oops!ReplyDelete
That 37C from Victoria Beach today appears to be suspicously high. Everyone else around them was 32-33c.. and those were inland from the lake. Might be a problem with the temperature sensor..ReplyDelete
Environment Canada has now issued a humidex for almost all of southern Manitoba. Tomorrow will be downright dangerous. Stay safe out there everyone!ReplyDelete
Dewpoints are SKYROCKING in Saskatchewan...ReplyDelete
Dewpoint of 26.8C in Lucky Lake.
LOL, sry guys! I'm dead tired and didn't even notice I wrote SKYROCKING instead of SKYROCKETING.ReplyDelete
Anyone wanna tell me why Dauphin and surrounding regions aren't under a severe thunderstorm warning right now? Absolutely getting slammed by a storm. Shows purple on EC radar, too...ReplyDelete
If we are gonna have a heat wave...might as well break a few records while we are at it.ReplyDelete
Today we should break that record!
High 36 predicted and no warnings out?ReplyDelete
yeah I agree with you rob something seemed to be wrong with the sensor, it probably read the temperature of the sun shining on it.ReplyDelete
