Variable Pattern the Next Few Days

     Today will mark the last cold day until next week as a southerly flow ahead of multiple clipper systems over the next few days ushers in warmer air.

     These multiple clipper systems will bring snowfall here and there. 3-5 cm of snowfall is expected in Winnipeg and for much of southern Manitoba later today into tonight. Winnipeg's snow should fall this evening into the overnight.

     After this clipper, another clipper system will follow right behind it for Friday into early Saturday. The bulk of the precipitation with this one will remain in central Manitoba where 5 to 10 cm is likely for the northern Interlake, and western and eastern Manitoba. There will likely still be some scattered flurries for southern Manitoba, especially along and north of the Trans-Canada but amounts should remain insignificant.

     A more significant low pressure system, potentially a Montana Low, will move in Sunday night into Monday. The storm will pull in lots of warm air ahead of it and cold air behind it. The result is an uncertain forecast for southern Manitoba, especially in the southeast. Temperatures near zero or even just above zero will make the precipitation phases and amounts difficult to predict. Freezing rain, ice pellets, rain will all be possible before the changeover to snow. Areas to the north and west in southwestern, western and central Manitoba could potentially see over 10 cm of snowfall with the system. Stay tuned for updates.

     Behind that low, things look cold Tuesday but there may a quick rebound mid week followed by another cool down late week. It's far to be certain and precise, but that's how it looks right now. It could be a bit of a roller coaster ride next week.

     Also of note, this November has become the first colder than normal November in 9 years (last colder than normal November was in 2003)!

  1. Snow has begun and will continue for much of the night. 2 to 5 cm likely for the city adding some challenge to the commute in the morning.
