Big warmup for early next week

Long range models continue to indicate a major push of warm air moving into southern MB early next week, with highs of 23C now predicted for Winnipeg for Monday. The warm airmass will be accompanied by strong southerly winds on Monday, especially through the Red River valley where southerly winds of 50-70 km/h are likely. Often in these situations, those southerly winds will keep temperatures down somewhat in Winnipeg, perhaps in the mid to upper teens instead, while areas to the southwest (Brandon, Portage, Morden) have a better chance of breaking the 20C mark. (For the record, the record high for Winnipeg on Monday is 29C back in 1958) Winnipeg may actually have a better chance of breaking the 20C mark on Tuesday when our winds shift into the west as a weak trof moves through. Whatever the case.. looks like some nice warm weather coming in for a couple days next week!

  1. Updated forecast now calling for a high of 17C for Monday.. which is more realistic than the 23C predicted yesterday. The big story for Monday though will be the winds.. tight southerly gradient will bring very strong southerly winds of 50-70 km/h up the Red River valley into Winnipeg.

  2. Sat Apr 12: Hard to believe it only got up to 7C today.. it felt a lot milder than that. If that's the case, tomorrow should feel downright balmy with 13C temperatures, lots of sun and light winds. Good day to finally take down those Xmas lights!

    By the way, any leftover snowbanks should really melt down over the next couple of days with those mild temperatures, low humidity (down to 20-30% in the afternoon), and increasing winds by Monday.

  3. The severe threat I was taking about on your last post quickly diminished as soon as most of you probably read it. The mild temperatures will be nice, a good thunderstorm would just be a bonus.

    What are the odds of other parts of Southern Manitoba reaching 20?

  4. Where's the rain? It looks like only 1mm of precipitation has fallen since April 1, and there doesn't appear to be much of any forecast in the near future!

  5. Personally I hope we have another dry summer. It means that we will likely see nicer, warmer weather if there is no rain. Also it prevents mosquitoes from coming.

    As for why there has been no rain, I think it is linked to La Nina somewhat. Rob would know better than I would though.

  6. Sensational Sunday.. clear blue skies, 12C temps, and most importantly, little wind which made those 12C temperatures feel more like 20! Lots of people outside today enjoying the nice weather. I see from the CTV webcam that the ice has now cleared from the Red River downtown.. ice covered only a few days ago. Yep.. spring is here! Will be a different feel tomorrow though as the light winds we enjoyed today get replaced by sandblasting southerlies to 70 km/h Monday! Still mild.. but not as pleasant as today thanks to those winds.

    As for the lack of precipitation.. yes, La Nina has had an influence, with a persistent storm track to our south and east where they have been getting pummeled this spring with lots of precipitation. Normally however our wet season doesn't start here until May and June, so we'll have to see if La Nina continues its dry influence.. or if Mother Nature makes up for it with a wet late spring.

  7. It certainly was a good day. Here it was the same, 12-13 degrees and light winds.

    I believe Tuesday will be the nicest day, with the warmest temperatures and lighter winds. Sure wish I was in Regina tomorrow, 28 degrees and much lighter winds at 30km/h!
