Alberta Clipper Brings Blizzard, Plunging Temperatures

A potent Alberta Clipper is bringing very strong winds and blowing snow to southern Manitoba this morning. In its wake, a surge of Arctic air will send temperatures plummeting back to bitterly cold values.

RDPS 10m Wind Forecast valid 15Z Tuesday February 1, 2022
Strong northwest winds will bring blizzard conditions to the Red River Valley on Tuesday morning.

Starting the day today, the clipper has moved off to the east and brought strong northwest winds as high as 60 gusting 80 km/h to the Red River Valley. This, combined with the 5–10 cm of snow overnight, is producing widespread blizzard conditions through the Red River Valley. Temperatures have also fallen from a high close to 0 °C near midnight into the -10 to -15 °C range. The snow will taper off today as temperatures continue to fall towards -20 °C by the end of the day.

Those strong winds will ease to 40 gusting 60 km/h by the end of the day. This will ease the blizzard conditions, but areas of poor visibility in blowing snow will likely persist across the region into the evening hours.

The wind will ease Tuesday night as skies clear and temperatures head to a low dipping below -30 °C. Extreme cold warnings may be issued if enough wind persists to hit -40 wind chills (only 10–15 km/h winds will be needed).

Bitterly cold temperatures with lows into the -30s will return to southern Manitoba later in the week.

Mid-week will bring plenty of sun but temperatures will stay quite cold with highs in the -20 to -25 °C range and lows dipping into the -30 to -35 °C range. Extreme cold warnings are all but a certainty on Wednesday night.

A weak disturbance will begin to push a little bit of warmer air into the province on Thursday night, bringing some cloud and a chance of some light snow. Skies should clear out again for Friday.

Long Range Outlook

The end of the work week will continue cold, but a substantial push of warm air and cloud will move into the region Friday night. Another 5–10 cm of snow could fall by Saturday evening.

After that, the region will see variable cloudiness with a general warming trend to the forecasts. Next week looks like it could be a return to seasonably mild temperatures with highs climbing back above -10 °C.

Today’s seasonal daytime high in Winnipeg is -11 °C while the seasonal overnight low is -21 °C.

One More Snow, Then The Deep Freeze Moves In

The Red River Valley will be grazed by a little more snow today, then a bitterly cold air mass will entrench itself over the region.

Very cold temperatures will move into Southern Manitoba by Wednesday morning and will persist into the weekend.

If the dump of snow yesterday wasn’t quite enough for you, a little more snow is possible this morning. One last disturbance will move through the region this morning, bringing 4–8 cm of snow to southeastern Manitoba. This area of snow will also graze the Red River Valley with 2–5 cm possible along a southwest to northwest line draped across the area.

The snow will clear out this evening, leaving behind clear skies as bitterly cold temperatures push into the region.

The big weather story for the rest of the week will be the cold temperatures that will stay locked over the region. Daytime highs will be around 15 °C below seasonal in the -30 to -25 °C range right to Saturday. Overnight lows will vary, but there is the potential for some very cold nights with lows dipping below -35 °C. Extreme cold warnings are a certainty for the region in the days ahead as wind chill values of -40 or lower are likely unavoidable.

A few flurries may be possible later this week, but the organized snowfall will be over for a bit after today.

Long Range Outlook

Forecasts have temperatures moderating beginning on Sunday and lasting through much of next week. This warmer weather will come with some snow as well with chances both next Monday and mid-week.

Today’s seasonal daytime high in Winnipeg is -12 °C while the seasonal overnight low is -22 °C.

Deep Freeze To Slowly Ease This Week

Winnipeg will gradually come out of the grip of bone-chilling cold that’s been in place over the last 10 days.

The polar vortex will slowly shift eastwards this week, allowing warmer temperatures to return to the Prairies. The temperature climb, unfortunately, is relegated mainly to the second half of the week. In Winnipeg, highs will only climb from around -23 °C today to -20 °C on Wednesday with a bit of a southerly wind at times. Overnight lows will hover in the low minus thirties.

Wednesday will be a turning point for southern Manitoba where the bitter cold finally begins to break down.

Long Range Outlook

The rest of the week will bring partly cloudy skies to Winnipeg as temperatures climb back to seasonal values by Saturday. No notable snowfall is in the forecast between now and next week.

Temperatures will likely climb above seasonal values and close to the freezing mark by Sunday or Monday. Get the shorts ready!

Today’s seasonal daytime high in Winnipeg is -8 °C while the seasonal overnight low is -19 °C.

Bitter Cold Continues Through The Weekend

The polar vortex will keep Winnipeg in its grip with dangerously cold temperatures persisting this weekend.

Below-seasonal temperatures will continue this weekend as the polar vortex keeps dangerously cold Arctic air locked over the region. Daytime highs will stay in the mid- to lower minus twenties over the next few days with overnight lows dipping into the minus thirties.

It’s still really cold.

Winds will be light in Winnipeg through the weekend, but with temperatures so cold wind chill values of -40 to -50 will be regular across southern Manitoba this weekend.

Skies will stay mainly sunny.

Long Range Outlook

This bitterly cold weather pattern will finally break down through the course of next week. The polar vortex will begin to weaken and push off to the east through the first half of the week. As it then curls back northwards and reforms over the Arctic, milder Pacific air will begin to spill eastwards over the Prairies.

Daytime highs next week will tart off in the -15 to -20 °C range, but will climb to slightly above seasonal values in the -5 to -10 °C range by the end of the week. Overnight lows look to stay in the -20s through Wednesday night, then begin to warm heading towards next weekend.

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -19 °C.
