Temperatures will continue to stay well above seasonal averages as Winnipeg’s mild winter continues.

A series of low pressure systems will move across the province over the coming days, bringing mild temperatures with them. The first one moved into the province overnight, bringing temperatures up to -2 °C with moderate southerly winds. The city will see some light snow first thing this morning as the winds taper off. A cold front will pass later this morning, bringing brisk northwest winds up to 40 gusting 60 km/h as skies clear. These winds will usher in colder air and send temperatures falling through the afternoon to around -10 °C. The winds will drop off this evening with temperatures falling to a low near -19 °C.

On Saturday, the city will see increasing cloudiness with strengthening southerly winds as the next low approaches. Temperatures will climb to a high near -5 °C with southerly winds in the 30–40 km/h range. The winds will ease on Saturday evening with some of the cloud cover breaking up. Temperatures will head to a low near -14 °C with some northwest winds picking up to 30 km/h as a cold front sweeps through. A few flurries will be possible along the cold front as it moves through.

Another surge of mild air will push into Manitoba on Saturday.

Warmer air will once again build back into the region on Sunday as the next low begins developing over Alberta. Skies will cloud over through the day with light snow likely Sunday night as the low moves through. The city will see a seasonably mild high near -4 °C and temperatures steady near -5 °C overnight.

Long Range Outlook

Next week will start off with more mild weather with highs near -5 °C and overnight lows in the -10 to -20 °C range.

Temperatures Remaining Above-Normal in Winnipeg

Winter will continue to be MIA as daytime highs continue to climb above freezing this week.

Another broad upper ridge spreading across the Prairies will keep mild Pacific air in place over the region.

To start the day, Winnipeg may see a bit of cloud or fog. If it does show up, things should clear out relatively quickly and leave behind mainly sunny skies. Temperatures will climb to a high just above 0 °C. The city will see light westerly winds through most of the day. More cloud will spread through the region tonight with lows dipping to around -4 °C.

On Tuesday, the city will see a few more clouds as a trough moves across the region. Winds will pick up out of the west midday behind the trough into the 20–30 km/h range. Once those westerlies kick in, temperatures should jump nicely for the afternoon and reach a high near +4 or 5 °C. Skies will mostly clear tomorrow night with winds easing and a low near -3 °C.

All of southern Manitoba will see mild temperatures climbing above freezing on Tuesday afternoon.

Temperatures will again climb above freezing to a high near +3 °C on Wednesday in Winnipeg. The city will enjoy partly cloudy skies with westerly winds picking back up into the 20–30 km/h range. More cloud will work into the region on Wednesday night with easing winds. The city should see a low near -3 °C again.

Long Range Outlook

The latter half of the week will likely see a fairly large pattern shift that will usher a return to more wintery conditions to the region. Forecasts show s strong winter storm moving from the Dakotas through Minnesota and into NW Ontario on Thursday through Saturday. This system will likely graze across portions of southern Manitoba and may bring accumulating snow to the region.

Behind this system, the upper ridging will over western North America will collapse, and the Polar Vortex will strengthen and slump into southern Nunavut. This will allow cooler air to spill southwards out of the Arctic and return temperatures closer to seasonal values for the weekend into next week. Winnipeg will likely see daytime highs in the -6 to -12 °C range this weekend and into the first half of next week. Overnight lows are forecast to dip into the mid-minus teens.

Today’s seasonal daytime high in Winnipeg is -8 °C while the seasonal overnight low is -17 °C.

Warm Weather Continues

There’s no sign of typical winter conditions in Winnipeg this week with temperatures remaining well above seasonal values right through the weekend.

Persistent upper ridging over the Prairies will keep a mild Pacific air mass over the region and keep typical winter conditions at bay. Winnipeg will see a warm day today with a high near +1 °C as skies clear later this morning. Westerly winds will continue through the day at 15 to 25 km/h. Temperatures will dip to a low near -8 °C tonight under mainly clear skies. Tomorrow will be more or less a repeat of today, but with nothing but sun and light winds.

Much of the southern Prairies will see temperatures climb above freezing over the coming days.

On Friday, slightly cooler temperatures will move into the area behind a weak upper-level disturbance. Skies will likely be a mix of sun and cloud and winds will be light. Skies will stay partly cloudy through the night with temperatures dropping to a low near -10 °C.

Long Range Outlook

Temperatures climb right back to near the freezing mark this weekend, with even warmer temperatures likely building in to start next week. Cloudier conditions forecast to move into the region on Tuesday, followed by a return to seasonal temperatures near the end fo the week.

Today’s seasonal daytime high in Winnipeg is -7 °C while the seasonal overnight low is -16 °C.

Mild Weather Continues

Warm temperatures will continue in Winnipeg as a slow-moving upper ridge continues its trek eastwards across the Prairies.

An upper ridge over the Prairies is bringing mild conditions to Winnipeg with plenty of sunshine. WIth the storm track deflected well to the north, the city will see dry conditions over the coming days. It will be easy to enjoy the late-fall warmth!

Winds will stay relatively light today out of the west up into the 20–30 km/h range. On Thursday, though, a low crossing the northern Prairies will strengthen winds in the Red River Valley out of the south into the 30–40 km/h range. On Friday, the city will likely see light winds to start the day then pick up out of the northeast as a large low complex begins to develop in the United States.

Much of southern Manitoba will see mild temperatures with daytime highs in the upper teens on Tuesday.

Overnight lows will also be mild over the coming nights with values in the low to mid-single digits.

Long Range Outlook

As we mentioned on Monday, a potent Colorado Low is forecast to develop this weekend and move into the southern Prairies. Forecast models are beginning to gather some consensus on the track of the system, trending towards a track that takes the low across southeast Saskatchewan on Sunday, western Manitoba on Sunday night, and northeastwards towards Hudson Bay on Monday.

This system will likely produce a swath of 20 to 50 cm of snow on its western and northern flanks, which would put it across southern Saskatchewan northeastwards into west-central Manitoba and onwards to Hudson Bay. This heavy snow combined with winds gusting up to 80 km/h would likely produce widespread blizzard conditions across the affected areas.

ECMWF Forecast Precipitation Type/Rate valid 00Z Monday November 9, 2020
All major forecast models have a potent winter storm moving into the Prairies on Sunday.

To the south and east of this low track, some light snow or rain is possible, as well as the potential for a broad area of low cloud and drizzle. Temperatures could stay rather warm in the southeastern quadrant of the storm with highs potentially climbing into the low teens.

Regardless of the storm track, this system will usher in much cooler weather for next week with daytime highs dropping below freezing for the rest of the week.

Today’s seasonal daytime high in Winnipeg is 2 °C while the seasonal overnight low is -6 °C.
