Update on Storm System

For today, we'll remain cloudy in Winnipeg and the RRV with drizzle and light showers at times. Generally mild as well with highs in the mid single digits this afternoon and evening.

Rain is expected to begin sometime this evening with light rain continuing into the overnight hours. Rain should transition to snow later in the overnight hours probably sometime between 2 and 5 am. In total, close to 5 mm of rain looks possible before switching over to snow, but this amount will depend highly on how early the switchover occurs.

The worst of the snow looks to be tomorrow morning. Snow may be quite heavy at times with significantly reduced visibility at times. Blustery northerly winds are expected to begin in the early morning as well with sustained winds of 50 and gusts to 70 km/h or more possible through the morning and afternoon. This will make for a very unpleasant day. The heavy wet snow combined with the strong winds could cause some localized power outages. Snow should end by the afternoon. In total, 5-10 cm of snow is expected for Winnipeg. Can't rule out a bit more if rain transitions to snow earlier than expected or if the snow is even heavier than expected.

Sunny, but cold for Thursday with highs in the -7°C to -4°C range. Chilly but a bit milder on Friday. So far, warmer conditions are forecast to return by the weekend and early next week which will allow melting of the new snow.

  1. Showers have already begun and will continue on and off through the rest of the day. End of the snowfall tomorrow keeps looking earlier and earlier, possibly ending as early as late tomorrow morning.

  2. Hey JJ, Mike here. I was wondering if you could visit my 2 new weather blogs. Which one would you like best? www.southmbweather.wordpress.com or michaelmcgregor7.wix.com/southmbweather I am in need of opinions on which one I should use. Oh and by the way how much snow should we get? How long will it last? Also when will it all melt, will it stay. Thanks. Sincerely Michael McGregor.

    1. Looks like rain should transition to snow overnight and then the bulk of the snow should taper off sometime later in the morning. I'm beginning to lean towards the lower end of the 5-10 cm range for us, probably around 3-7 cm. So not a major snowstorm by any means for us, depending on your definition of major... That wind will be nasty tomorrow though. No the snow wont last, it is spring after all. Warmer conditions are expected for the weekend and early next week as already mentioned.

      I think I prefer the wordpress blog, but that's your choice. Pick one that you like and go with it.

  3. Looks like about 4 to 5 mm of rain so far today in Winnipeg. Sure nice to see the rain again... Not looking foreward to waking up to snow tomorrow morning!

  4. Looks like about 4 to 5 cm of snow in Winnipeg as of 8 am. Snow is now tapering off so we shouldn't see much more accumulation.

    A bit more snow looks possible on Friday but I'm not expecting much. Looks like another system for late Saturday and early Sunday with most likely rain. And yet another system looks possible around Tuesday-Wednesday next week. I wont go into detail about these systems yet as they are still pretty far away... But just so you know, looks like a more active pattern we're in right now.

  5. The earlier ending of the snow has allowed clearing to move in earlier than expected yesterday. Good news as this is allowing for a rapid melt of the new snow pack this afternoon. Can really see it dissapear on visible satellite, especially in the RRV where amounts were lower.

  6. Lots of sun today but chilly with a high around -3°C or -4°C or so. Possibly down to the minus teens tonight; I'm thinking -10°C to -12°C. Fairly cloudy tomorrow as a weak system brings snow to our west. We may see a few flurries in Winnipeg, but if we do there wont be much at all.

    Fast-moving clipper system races through late Saturday. Beware of that perfectly sunny forecast from Environment Canada; there likely will be some increasing cloud. Should manage to reach at least mid single digits for a high and these warm temperatures will persist in the evening. There will also be very strong southerly winds through the day, likely sustained not far from 40 km/h and gusts to 50-60 km/h at times. Rain asociated with the system is expected to begin in the evening but not last very long, likely just a few hours. 2-5 mm not out of the question.

    Remaining mild behind the system for Sunday with highs in the high single digits.

    1. 3-7 mm most likely for Winnipeg tomorrow night, but there definitely could be a bit more if we get under some heavier rains. Could even be some thunderstorms in North Dakota tomorrow and some of these may skirt the US border, especially in southwestern Manitoba before sunset. Too uncertain this far out about mid week so I wont go into detail.
