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.
ReplyDeleteuh jeeze not again there going to far north for us to get to. I'll have to wait for another storm.
ReplyDeleteYeah 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).
ReplyDeleteOnly 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
checks radar.
ReplyDelete*FAINTS*
30 minutes is too far to drive for storm-chasing?! Maybe you won't even have to leave your driveway.
ReplyDeleteNice cell heading right for Woodlands.. looks impressive on radar and Woodlands webcam..
ReplyDeleteLooks 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 east
ReplyDeleteWow.. 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..
ReplyDeleteare tornadoes possible this evening? That would definitely be a dangerous situation given how close it is to populated areas around WPG.
ReplyDeleteThanks
new cell popping along the trans-canada.. and anvil building south on satellite looks like Winnipeg will get hit finally
ReplyDeleteStormchasing not required.
ReplyDeleteSun's beginning to set, so we'll probably see these storms begin to weaken a bit.
ReplyDeletenice lightning show here in Rivergrove just south of Shooters golf center. Am on my north facing patio enjoying it with a glass of vino!
ReplyDeletewind is from the south west and formation is clearly tracking to the northeast of me.
enjoy!
Winnipeg folks, congrats. This is your baby! Hope you get some much needed rain and an intense show.
ReplyDeleteThanks Derek haha.. yeah intense cell heading straight for YWG
ReplyDeleteGetting some decent wind gusts in the city.
ReplyDeleteNo more complaining after today?
ReplyDeleteYahooooo!!! Lots of rain and a beautiful show in Headingley!
ReplyDeletePretty amazing. This storm actually smells like the lake!
ReplyDeleteJust getting slammed with a major storm!!!! WHoa!!!!!!!
ReplyDeletewow.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!
ReplyDeletePerimeter and #8 is rocking and rolling. Winds are huge and rain comin in buckets. Lightning is intense.
ReplyDeleteVery rain in St James!
ReplyDeleteStrong 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.
ReplyDeleteHail in central Winnipeg
ReplyDeleteMarble sized hail here in Tuxedo! Lovely wind gusts!
ReplyDeleteI had no hail in St James.... just blinding rain!!!
ReplyDeleteNot a drop out here north of Elie :(
ReplyDeleteHail just went through lindenwoods. Mostly marble size. Seems to be settling down now.
ReplyDelete15 mm of rain at Rob's place!!
ReplyDeleteA 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.
ReplyDeleteNorth beaches get the warning. Wpg gets the goods
ReplyDeleteGot a shot of that line of storms forming to the west, with the anvil of the northern storm over top. Image on my name.
ReplyDeleteMore noise and show than we've had all summer
ReplyDeleteNice 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.
ReplyDeleteContinous lightning in the St. James and Charleswood area: no thunder though. Safe for observation and photo-taking!
ReplyDeleteRob!
ReplyDeleteHow 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.
ReplyDeleteNo thunder in St. James?! Perhaps a good ear wax cleaning is in order.
ReplyDeleteDid anyone get any wind damage????
ReplyDelete15-20mm 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.
ReplyDeleteWow.. 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.
ReplyDeleteAs 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!!!
ReplyDeleteLooking 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.
ReplyDeleteRight.. and how many times did those signs work out for us this year? :)
ReplyDeleteRob!
ReplyDeleteWhen 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.
ReplyDeleteFrom 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.
ReplyDeleteOn the CWB network
ReplyDelete27mm 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..
ReplyDeleteWon'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.
ReplyDeleteHow blazé we were last year by mid August.. this would have elicited a few comments and this year 53 comments in 5.5 hours
ReplyDeleteOur 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.
ReplyDelete20.8 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!
ReplyDeletemm/hr of course!
ReplyDeleteGo to the weather network for Some awesome pictures of the storm!!
ReplyDeleteCHECK IT OUT!
Measured the largest stones here in east Charleswood and got toonie sized hail with some quarter to loonie size.
ReplyDeleteNo hail in Westdale (west Charleswood).
ReplyDeleteDid the rest of eastern Manitoba get the rain? I hope so - I want the travel ban lifted!
ReplyDeleteAbout 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..
