Snow Gives Way to Sunny but Cool Weekend

Snow will come to an end over the region today as the storm that’s been stalled over the region finally moves east. Sunnier skies will return for the weekend as a high pressure system settles over the province.

RDPS MLSP & 10m Wind Forecast valid 18Z Saturday April 22, 2023
A broad area of high pressure will settle across the eastern Prairies this weekend.

Snow continues to wrap into southern Manitoba this morning, but conditions will improve through the day. As the low responsible for our weather continues to trundle eastwards into Ontario, snow gradually weaken and taper off over southern Manitoba. It will be a bit of a slick and slippery morning as temperatures dip below zero and combine with fairly strong northerly winds near 50 gusting 70 km/h.

Temperatures will rebound to a high of only around +2 °C.

Skies will clear out tonight as winds ease to around 20 km/h. Temperatures will dip to a low in the mid-minus single digits.

For th weekend, a ridge of high pressure will build into the region and bring cool but settled conditions. Winnipeg and area will see variable cloudiness through the weekend with daytime highs in the mid- to upper-single digits. Overnight lows will likely dip into the -5 to -10 °C range.

Long Range Outlook

Next week will start off with quieter weather as temperatures gradually move towards more seasonal values. Some rain may be possible across the region late next week.

Today’s seasonal daytime high in Winnipeg is 13 °C while the seasonal overnight low is 0 °C.

Temperatures Gradually Easing Back Towards the Freezing Mark

Below-seasonal temperatures will continue in Winnipeg this week as temperatures gradually ease back towards the 0 °C mark. The cool conditions and strengthening sun will help flood conditions a bit by gradually evaporating water from the snow pack over the region.

Temperatures will begin a push back towards seasonal values later this week.

The coldest night of the week is now behind us, and the Arctic high responsible for it is gradually shifting off to the southeast. Temperatures will remain cool today with highs once again near -10 °C and lows dipping back to around the -20 °C mark tonight. At least we’ll see plenty of sunshine!

After that, a gradual warm-up will begin as the Polar Vortex begins to weaken over Hudson Bay. This won’t mean a huge warmup for us though, because rather than shifting back into the High Arctic, the Polar Vortex will still stay relatively far south and keep a northwesterly flow over the region. Daytime highs will jump back into the -5 to 0 °C range mid-week with overnight lows in the -10 to -15 °C range.

The region will see some cloud on Thursday as a low pressure system drops out of the Northwest Territories into central Manitoba. Any snow will likely remain well to the north of Winnipeg, perhaps not even moving out of central Manitoba. More sun should return to the region on Friday, but some cloud might work its way into the region as a low passes by to the south of the province.

Long Range Outlook

Heading into the weekend, temperatures will finally reach freezing, with highs of above zero even possible. A system passing through the region on Sunday will bring some more cloud to the region along with a chance of snow.

Today’s seasonal daytime high in Winnipeg is 4 °C while the seasonal overnight low is -7 °C.

Relatively Pleasant Spring Weather Ahead

It will be relatively pleasant spring conditions in the Winnipeg area over the next few days as seasonably cool temperatures combine with a mix of sunshine and flurries.

An Arctic cold front will sweep through southern Manitoba to end the weekend, bringing colder weather to start next week.

While the seasonal daytime high for the region has finally climbed above the freezing mark, temperatures in Winnipeg will run just a tad on the cool side over the coming days. Highs will climb very close to freezing today and tomorrow, with the more snow-free urban parts of the city possibly reaching the seasonal high. Overnight lows will dip into the -5 to -10 °C range tonight.

A cold front will swing through the region on Saturday, bringing mixed skies to the region with a slight chance of flurries overnight. Winds will pick up out of the north into the 20–30 km/h range and then ease with the flurries overnight. Overnight lows will dip into the -15 to -20 °C range behind the front.

Temperatures will cool off a bit for Sunday with highs dipping back towards the -5 °C mark. There will be a bit more sun, which means again that some areas will likely see temperatures climbing closer to the freezing mark if they have less snow. Another cold front will swing into the region on Sunday night, ushering an Arctic air mass back into the province along with some more flurries.

Long Range Outlook

Seasonably cool weather will start off next week with overnight lows close to -20 °C and daytime highs in the -5 to -10 °C range. It will start to warm up mid-week followed by a chance for some snow in the second half of the work week.

Today’s seasonal daytime high in Winnipeg is +2 °C while the seasonal overnight low is -9 °C.

Arctic Blast Brings Bitterly Cold February Temperatures

The Polar Vortex has dropped southwards out of the High Arctic, once again bringing a surge of bitterly cold temperatures to the Canadian Prairies.

The Polar Vortex has dropped southwards out of the High Arctic, once again bringing a surge of bitterly cold temperatures to the Canadian Prairies.

Temperatures falling into the minus 30s on Wednesday night will combine with light winds to produce wind chill values of -40 or colder across many parts of the southern Prairies on Wednesday morning.

Temperatures will plummet well below seasonal values in Winnipeg this week as cold air from the Polar Vortex spills into the region. Daytime highs will sit several degrees below the seasonal overnight lows through the rest of the work week. A high near -20 °C today will fall into the mid-minus 20s on Wednesday, then gradually recover back towards -20 °C again through Thursday and Friday.

This cold air will be represented at the surface by a potent Arctic High that extends from Yukon Territory southeastwards into the Prairies before turning east through NW Ontario. This feature will also send overnight lows tanking, dipping into the -25 to -30 °C range most nights, with a chance for a couple lows below -30. 

The bitterly cold temperatures combined with light winds will likely result in extreme cold warnings at times over the coming days.

That cold will bring plenty of sunshine to the region. The one exception will be on Thursday when a passing low in the United States spreads some cloud across the region. The cold air over southern Manitoba should keep any snow south of the border, though. The sun will return on Friday.

Long Range Outlook

Fortunately, the batter cold won’t likely stick around for very long. By the weekend, a series of potent low pressure systems moving through the Atlantic will help dislodge the Polar Vortex and pull it eastwards. This will allow a more westerly flow to develop over the Prairies and bring warmer weather back to the region.

This will bring mixed skies to the region as temperatures gradually warm with near-seasonal temperatures back in the region by Sunday.

Next week will bring variable cloudiness to the city with a couple chances of some light snow and mild temperatures.

Today’s seasonal daytime high in Winnipeg is -7 °C while the seasonal overnight low is -17 °C.
