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)!

Cold

     A clipper system brought 4 cm of snowfall to Winnipeg yesterday in a period of a couple hours. Blowing snow was an issue causing severely reduced visibilities in and around the city. An additional 2.0 cm of snow fell overnight bringing the total for this system to 6 cm in the city.

     The bulk of the snow has ended for now, other than for the odd flurry or two this afternoon and evening. Another band of snowfall is expected tomorrow night. We're only expecting about 1 to 3 cm with it however, so it is not expected to be very significant. The main story will be the cold for the next few days as overnight lows dip close to -20°C tonight, and we could possibly even get as low as the mid minus twenties locally. Things wont warm much in the afternoon as highs remain in the minus teens. These cold temperatures are expected to continue until late week as another clipper system is expected to move in. Another couple cm will be possible with that.

     The way this month is going, this may be the first colder than normal November since 2003!

Mild For a Few Days

     Daytime highs are expected to rise above zero through most of southern Manitoba today thanks to brilliant sunshine and a southerly or southeasterly flow. Areas with minimal snowcover and heavily forested will warm the most, such as in southeastern Manitoba. Sprague, which doesn't have much snow on the ground, has already risen to 7°C as of 11 AM and only saw a morning low of -2°C. In Winnipeg, we are expected to reach about 1 or 2°C at the airport, but within city limits highs between 3 and 5°C are not out of the question locally. This will allow for some of this snow cover to melt.

     Mild weather is expected to continue Monday through to Wednesday with daytime highs above zero expected. Again warmest temperatures will remain in southeastern Manitoba and within the city limits of Winnipeg.

     Cooler and more unsettled weather is expected late week with the potential for some insignificant snowfall (appears to only be about 2-5 cm at this point) which will likely slicken roads again.

     Beyond that, no major prolonged cold outbreaks expected in the next 2 weeks.
