First snowfall arriving Sunday?

As I mentioned a couple of days ago, it looks like Winnipeg and much of Southern MB may be seeing the first general snowfall of the season by Sunday night. An Alberta clipper system will track across southern MB on Sunday bringing an area of snow with it. Precipitation will move into western Manitoba from Saskatchewan Sunday morning, reaching Winnipeg by afternoon. Precipitation in Winnipeg may start off as a mix of rain and wet snow at first, but will change to all snow by evening as colder air moves in. The snow may fall heavily for a time Sunday evening before ending overnight. Accumulations of 2 to 5 cm are possible, but some of that will melt due to the still warm ground. Colder air will sweep in behind the system Sunday night into Monday, with temperatures falling below freezing. As a result, there could be some icy driving conditions for early Monday.

  1. The area of light snow has moved into southwest Manitoba this morning and is moving east into the Red River valley. However the general area of precipitation is weakening, so we shouldn't see too much in the way of snow here in Winnipeg. The precipitation may even start off as some light rain with temperatures up to +3 right now. We could still see some light snow tonight as colder air moves in.. but at this point, only trace amounts of snow are expected. The exception may be to the southeast of Lakes Manitoba and Winnipeg which could see some locally heavier bands of lake effect snow overnight through Monday.
