Snow spreading into southern MB.. risk of freezing rain overnight and Tuesday morning

A storm system over southern Saskatchewan will be spreading an area of snow into southern Manitoba tonight into Tuesday, especially over the Riding and Duck Mtn regions where snowfall warnings have been issued for 10-20 cm of snow. Snow is likely mainly north of the TransCanada into the Interlake regions, while areas along and south of the TransCanada will see a risk of freezing rain overnight into Tuesday morning as warmer air aloft spreads into the region. A cold front trailing from this system will push across southern MB late Tuesday ushering in colder air Tuesday night into Wednesday.

  1. Someone is getting a good dumping of snow tonight. Bright Banding of snow is showing up on radar over the Interlake!!

  2. Around the 15th of the month Weather net is calling for temps to be approx 16 degrees. I know that is a long way off but that would be an amazing temp for middle of March

  7. Next week looks warm.
    Things looks downright hot for areas to the south of us in South Dakota and southern Minneasota LOL....Temps there could hit 20-25 C!!!

  8. This is totally off-topic, but I found an excellent resource on general weather patterns for the Prairie Provinces. I'm posting a link to this one chapter (it's a PDF) because it discusses summer weather, including formation of thunderstorms, which has always been my foremost love. :P For anyone interested, enjoy! Hope you find it useful and educational.

  9. DAN GF or Rob!

    I see that NWS Grand Forks has put some Space weather info on their homepage!!!
    Why does the weather service put space weather updates on their "weather page"???

    Does Canada have a similar agency???

  10. Anon: Turns out I have that same link on my blog, did you find it there? nice that you found it is a great resource when it comes to our weather in the prairies.

    As for our weather I cannot beleive the fact that we are finally going to see plus temps, several models I looked at are favouring towards 16c+ weather in the Red River valley! as Rob mentioned before 16C weather was experienced back in 2000, this weather is starting to turn out exactly like that year!

  11. +16 is not likely if we have a snowpack present though...

    ReplyDelete
  12. You do prove a good point, I forgot to factor that in.....
    10C seems more reasonable.

    ReplyDelete
  13. If the +16 is set for around Wednesday or Thursday I would guess that most of our snowpack will be gone by that time as temps are forecasted above zero over the weekend already and that fresh snow will evaporte quickly

  14. Some serious snowfall going on this morning. I see EC changed their forecast at the last minute from 30% flurries to snow this morning. Radar shows some heavier snow for the next little while.

    ReplyDelete
  15. Looks like some bright banding going on as well.

  16. For a few mintues it was blizzard like conditions in downtown when that "yellow" on radar hit the area!!

  17. Hey guys, its coming down pretty good out here in ste.anne any idea of how much we might end up getting?

  18. Winds in Portage La Prairie are
    63km/h -74 km/h as of 10:00.

    Blowing snow will be an issue on the highway!

    ReplyDelete
  19. Maybe 1 cm max. The line is moving pretty quickly. Winds are picking up behind this system now.

    ReplyDelete
  20. Winds are now sustained at 52 km/h at the airport at 10:51

    ReplyDelete
  21. Went outside, and man are the winds intense. Especially when they whip around the buildings downtown!!

    ReplyDelete
  22. Mike: Nope, I found that source through a Google search. I'm going on a roadtrip to Alberta later this summer (early August) and wanted to see how the weather in Alberta and Saskatchewan would compare to us. :)

    ReplyDelete
  23. Boy is it ever blowing out there,winds being reported as gusting up to 63km/h hope it doesn't last long!

    ReplyDelete
  24. Thanks for letting me know Anon, I was wondering about that.

    ReplyDelete
  25. Wow, could not even see from Hydro Pole to Hydro Pole along Highway 12... Total whiteout, with significant drifting across the Highway starting to occur!

  26. Oh my.....there is a black out of the satalite view on UofM weather central website. Is that the solar storm hitting???? Does this mean the end of the world :-P

    Looking at the radar this morning on EC website between Dauphin and Portage there appears to be a fairly stationary line. I have never seen the colors that it is producing. Between 5:00am and 6:00am it is showing snow rates of up to 20cm per hour. Would this be a false radar return or maybe something connected to the sun magnetic storm or just a software issue?

    ReplyDelete
  28. Major heat wave coming this weekend :-)
    Snow should be all gone by end of next week~~~

  29. Daryl..

    That stationary line on radar this morning was just false echoes from the edge of the Riding Mountains. This sometimes happens when there's an inversion, and the radar beam is deflected down into higher terrain, which shows up as a line on radar. You'll know it's false because it just sits there and then fades as the inversion weakens as the temperature rises.

    By the way, apologies for the lack of posts this week.. I've been enjoying a few days down in Niagara (sunny and 17C on Wednesday!) Back tonight.. (just in time for the big warm up!)

  30. Rob!!!!

    Check out the Winnipeg airport observations on the wind from last night. It was 48km/h sustained one hour and then...BAM....it was dead calm!!! Weird......

    BTW, this week looks amazingly warm. Areas that our snowfree well to our south ( such as Minneapolis) could hit temps in the high teens or maybe even 20 C!!!

    ReplyDelete
  31. daniel..

    That calm wind observation does look strange.. I suspect it was a coding error of some sort (or wasn't entered) and showed up as "0" for wind. I can tell you it sure wasn't calm when I landed at the airport just after midnight last night.. that south wind was howling while waiting for a cab (made it seem a lot colder than -4c!)

    But now the big warmup begins.. we still have quite a bit of snowcover to lose before we can hit double digit temps here, but if we can get some melting at night, and some rain.. it could go fast. Like you said, snowfree areas could be seeing temperatures near 20C by the end of the week.

  32. TWN saying 22°C for next Saturday. So high it's off the charts on their 14-day forecast graph.
    The best fantasy forecast I've seen in quite a while. 'Fantasy if the key word' ;)

    ReplyDelete
  33. Hey everyone~

    Looks like there is potential to SMASH some records this week, especially next weekend if can hit the upper teens!!

    Spring is here!!!

    ReplyDelete
  34. This is from the NWS GRAND FORKS discussion:

    12 UTC BIS/ABR SOUNDINGS SHOW VERY STRONG SURFACE INVERSIONS WITH
    900 HPA TEMPERATURES FROM +16 TO +18 C.

    Question: would it even be possible to get those temps to the surface??? What would need to happen?? Anyone??

    ReplyDelete
  35. daniel..

    16-18C at 900 mb could easily get to the surface at this time of year provided there's no snow cover, lots of sun, and some wind to mix out the airmass in the low levels. I see KBIS is actually predicting highs of 16-20C in snowfree SW ND today.

    ReplyDelete
  36. Thanks Rob!

    I see Minot has already broken their daytime record and it's only 11:00 in the morning.Unreal!

    Portage La Prairie is already at 8 C! Record high possible there!!

    ReplyDelete
  37. Oh my bad!!!
    I was looking at Bismark's temp

    Minot will break their temp record later I'm sure~~

    ReplyDelete
  38. 71F (22C) at Bismarck as of 2 pm.. easily breaking today's record of 64F (18C) set in 2008.

    Double digit temps today in Portage and McCreary at 10C with plenty of 5-8C temps elsewhere across southern and even central and northern MB. Forested areas (which absorb heat opposed to reflective snow covered areas) will see warmest temps this week, as well as areas with little or no snow cover. What a dramatic turn around to spring!
