A cold front over western Manitoba late this afternoon is triggering a line of thunderstorms mainly northwest of the Red River valley through the western Interlake areas late today, with some potentially severe storms developing. (see 5:50 pm radar image left) A severe thunderstorm watch has been posted for much of southern Manitoba including Winnipeg and the Red River valley for the potential for severe thunderstorms into this evening as the cold front approaches. It looks like the bulk of storms will pass to the north of Winnipeg through the Interlake region, but the potential is there for isolated storms to develop further south. This front will usher in a cooler airmass for the next few days with highs only in the low 20s through the weekend. Warmer weather is expected to return to southern MB early next week.
Well, I won't be out of luck for this round of storms. I'm going stormchasing tonight. I'll let you know what i see when I get back.ReplyDelete
uh jeeze not again there going to far north for us to get to. I'll have to wait for another storm.ReplyDelete
Yeah once again lack of lift is inhibiting convection.. best chance for Winnipeg would originate at the intersection of the outflow from the interlake storms and the cold front (just north of Portage).ReplyDelete
Only cumulus fields are: north where convection is occurring, and east where the dark forests and hillier terrain are enhancing heating.. so convection may build south along the front east of Winnipeg if there is enough left over instability
30 minutes is too far to drive for storm-chasing?! Maybe you won't even have to leave your driveway.ReplyDelete
Nice cell heading right for Woodlands.. looks impressive on radar and Woodlands webcam..ReplyDelete
Looks like some attenuation of the RADAR as the cell moves right over Woodlands.. we'll see what we are dealing with as soon as the line shifts a bit eastReplyDelete
Wow.. southwest flank of cell is looking nasty.. heading towards Warren/Stonewall areas.. may clip north perimeter of Winnipeg. Even has a bit of a hook to it..ReplyDelete
are tornadoes possible this evening? That would definitely be a dangerous situation given how close it is to populated areas around WPG.ReplyDelete
new cell popping along the trans-canada.. and anvil building south on satellite looks like Winnipeg will get hit finallyReplyDelete
Stormchasing not required.ReplyDelete
Sun's beginning to set, so we'll probably see these storms begin to weaken a bit.ReplyDelete
nice lightning show here in Rivergrove just south of Shooters golf center. Am on my north facing patio enjoying it with a glass of vino!ReplyDelete
wind is from the south west and formation is clearly tracking to the northeast of me.
Winnipeg folks, congrats. This is your baby! Hope you get some much needed rain and an intense show.ReplyDelete
Thanks Derek haha.. yeah intense cell heading straight for YWGReplyDelete
Getting some decent wind gusts in the city.ReplyDelete
No more complaining after today?ReplyDelete
Yahooooo!!! Lots of rain and a beautiful show in Headingley!ReplyDelete
Pretty amazing. This storm actually smells like the lake!ReplyDelete
Just getting slammed with a major storm!!!! WHoa!!!!!!!ReplyDelete
wow.heavy rain here in Rivergrove with some nice gusts. no hail... so my new roof as a result of last year is still in good shape!ReplyDelete
Perimeter and #8 is rocking and rolling. Winds are huge and rain comin in buckets. Lightning is intense.ReplyDelete
Very rain in St James!ReplyDelete
Strong Wind gusts with small tree branches down!!! Continueous lighting!!!
Very good show!!!
power just cut out for a second! HAIL coming down now too! Rivergrove just south of perimeter.ReplyDelete
Hail in central WinnipegReplyDelete
Marble sized hail here in Tuxedo! Lovely wind gusts!ReplyDelete
I had no hail in St James.... just blinding rain!!!ReplyDelete
Not a drop out here north of Elie :(ReplyDelete
Hail just went through lindenwoods. Mostly marble size. Seems to be settling down now.ReplyDelete
15 mm of rain at Rob's place!!ReplyDelete
A storm at last.... I was coming home from work and watched that tower explode to the west of Winnipeg. I got home just in time!
That was kind of lackluster in some parts of the city. Others, some action, but nothing too much.ReplyDelete
North beaches get the warning. Wpg gets the goodsReplyDelete
Got a shot of that line of storms forming to the west, with the anvil of the northern storm over top. Image on my name.ReplyDelete
More noise and show than we've had all summerReplyDelete
Nice show finally. Some dime sized hail here in Windsor Park, lost power for about 2 minutes and probably received the 14mm of rain to eliminate us from the driest JJA title.ReplyDelete
Continous lightning in the St. James and Charleswood area: no thunder though. Safe for observation and photo-taking!ReplyDelete
How were things in your part of town??
Like a snow hauling trucker after the long wait for a Winter snow storm, the Auto body and collision centers are ecstatic. Dents Dings and more dents.ReplyDelete
No thunder in St. James?! Perhaps a good ear wax cleaning is in order.ReplyDelete
Did anyone get any wind damage????ReplyDelete
15-20mm where I am. Was just in yard and no puddles or standing water anywhere on lawn. The ground sucked it up like a sponge. We really needed 3 times the rain.ReplyDelete
Wow.. wasn't that a unexpected surprise! As that cell was intensifying to the northwest of Winnipeg, I took a quick drive up Saskatchewan Ave up to Inkster.. wow, what a terrific view point. Great shelf cloud heading towards the airport with some hints of a lowering wall cloud at times. Got extremely dark..like night.. with heavy rain, strong winds and some hail. As I headed back home, I saw it was still developing to my south and west and I drove in pounding rain all the way to my place in Charleswood. I can't believe how quickly that line built southward. I really expected it to clip the north part of Winnipeg. Best storm of the year and we weren't even expecting it! Great light show still on going to the east.ReplyDelete
As noted 15 mm of rain at my place in about 15 minutes with a peak rain rate of 162 mm/hr at 9:03 pm. Rain was gushing out of the downspouts like a water cannon. Guess I don't have to water my lawn tomorrow :)
Sounds like you had a blast Rob!!!ReplyDelete
Looking at the radar replay...looks like the WHOLE city got a least something!!
Not expecting it? Maybe not according to the public forecast, but the signs were there yesterday already.ReplyDelete
Right.. and how many times did those signs work out for us this year? :)ReplyDelete
When you were standing out in no man's land did you notice how the rain was at least 5 mins behind the gust front. It was here in St James.
Also did you see the very low hanging scud clouds while the southern flank of the storm was building???
Looks like a general 15-20 mm across the city according to CWB mesonet with a 27 mm reading at the North Perimeter at Brookside. Will be interesting to see how much the airport officially got.. but I suspect it will take us out of driest summer contention, or very close to it.ReplyDelete
From that perspective, yes it's a nice surprise. But yesterday's charts were showing a cold front with rapidly dropping 500MB heights, entering an area with good LI and SHOWALTER and decent CAPE after good daytime heating. The only question was sufficient dewpoints, but something was going to happen whether it hit Winnipeg or not.ReplyDelete
On the CWB networkReplyDelete
27mm at Rte 90 North and
18mm at Crane School in Fort Garry
23mm At Anola
Yes, I noticed the low hanging scud.. sometimes vertical appendages. Very chaotic sky with that line coming in.. I almost forgot what a thunderstorm looked like! Nice treat for us finally..ReplyDelete
Won't help my farmer friend in Sanford though.. looks like line went just to his north!
Cable was out in south-east Wpg, very intense lightning, rain, and wind gusts, pea size hail for about 2min. Finally the perimeter domes got wrecked.ReplyDelete
^Oh and forgot to say 17mm at my station.ReplyDelete
How blazé we were last year by mid August.. this would have elicited a few comments and this year 53 comments in 5.5 hoursReplyDelete
Our one and only most memorable this summer.
Forgot to mention that as I was driving along Saskatchewan Ave towards the storm, a group of people were still outside playing baseball even though the sky was getting ominously dark, and lightning was getting dangerously close. I can't believe people still don't know basic lightning safety, or don't take it seriously.ReplyDelete
20.8 mm at my place in Transcona. Some pea-sized hail also. Max rain rate of 126.6 mm. All in all, not a bad storm with some excellent lightning and structure!ReplyDelete
mm/hr of course!ReplyDelete
Go to the weather network for Some awesome pictures of the storm!!ReplyDelete
CHECK IT OUT!
Measured the largest stones here in east Charleswood and got toonie sized hail with some quarter to loonie size.ReplyDelete
No hail in Westdale (west Charleswood).ReplyDelete
Did the rest of eastern Manitoba get the rain? I hope so - I want the travel ban lifted!ReplyDelete
About 5-10 mm over eastern MB from that line last evening.. maybe locally heavier amounts. I don't think that would be enough for them to lift the travel or fire ban..ReplyDelete
