Colder Weather to Push Into Southern Manitoba

There will be a shift in the weather across southern Manitoba this week as a cold front sweeps through the region and ushers in wintery temperatures. The cold snap will be short-lived, though, with a relatively quick return to near-seasonal conditions.

An Arctic high will begin pushing into the Prairies on Wednesday night and allow colder air to spill southwards through the region.

After a rather busy period over the last few weeks, it’s nice to be back with some time to forecast. I hope you’ve all been able to enjoy the pleasant extended warmth so far this November. The cold weather will come eventually, so it’s nice to keep it at bay as long as possible late into the year.

Heading through the rest of the week, the main weather system will be a clipper-like system that tracks across the southern Prairies on Tuesday night into Wednesday. Daytime highs will continue to sit around 0 °C or a bit warmer as northwest winds taper off and shift to light southerlies. Winnipeg will see plenty of sun today, but some cloud will move in tonight and stick around into Wednesday morning.

A cold front will sweep through the region later on Wednesday, ushering in moderate northwest winds of 30 to 40 km/h. Skies will clear out with the winds and temperatures will begin to drop. An Arctic high will slump into the region, bringing much cooler weather with it.

For the second half of the week, overnight lows will dip into the minus teens; likely into the -15 to -20 °C range Wednesday and Thursday night, and then moderating into the -10 to -15 °C range for Friday night. Daytime highs will also follow suit, dipping into the -5 to -10 °C range.

Long Range Outlook

A disturbance will move into the region on the weekend, bringing some cloud and a chance for some light snow as well. With the cloud will come temperatures that moderate back towards seasonal values, dipping slightly cooler at times.

Today’s seasonal daytime high in Winnipeg is -4 °C while the seasonal overnight low is -12 °C.
