A pair of low pressure systems working their way into the Prairies will spread snow eastwards into the Red River Valley today.

Under cloudy skies, Winnipeg will see temperatures climb to a high near -11°C today as snow develops through the morning hours. Once developed, the snow will persist through Friday night before tapering off on Saturday morning. Although it will snow for quite a while, it won’t be a particularly large snowfall event, with just 2 to 5 cm of snow expected in the Red River Valley. Further west, in parts of southwestern Manitoba and into the Parkland areas of western Manitoba, amounts will be higher with 4 to 8 cm expected by the time it tapers off. Temperatures will remain steady near -11°C tonight in Winnipeg with winds out of the east-southeast at 15 to 20 km/h.

Snow will taper off on Saturday morning, then some sunny breaks will work into the Red River Valley through the afternoon. Temperatures will climb to a high near -7°C with light winds. Mixed to cloudy skies are expected on Saturday night as temperatures dip to a low near -10°C.

Milder air will continue moving into the region on Sunday as Winnipeg climbs to a partly cloudy high near -4°C and winds out of the southwest at 15 to 20 km/h. Clouds are forecast to build back into the region on Sunday night, bringing a chance of flurries to the region as temperatures drop to a low near -7°C.

Long Range Outlook

Another big pattern shift will occur in the coming week, this time bringing the deep freeze.

A significant low pressure system will work its way across the Prairies on Monday and once it passes, a potent Arctic ridge is forecast to build into the Prairies from the northwest. This will usher a much colder air mass into the region that will plunge daytime highs down into the low minus teens by the later half of the week.

So get out there and enjoy the mild winter weather; it doesn’t look like it will be sticking around for too much longer!

Winnipeg’s seasonal daytime high is currently -10°C while the seasonal overnight low is -20°C.

Winnipeg will see several batches of light snow over the coming few days as temperatures slowly slide towards seasonal values.

Today will bring falling temperatures to Winnipeg as a cold front slumps south and brings another shot of light snow through the region. Not much snow will fall, perhaps 1 to 2 cm, and it should taper off by the afternoon. Winnipeg will see breezy northwesterly winds around 30 gusting to 50 km/h, but over the western Red River Valley they’ll be a bit stronger and closer to 40 gusting 60 km/h. The winds will taper off through the afternoon across the region as temperatures fall to around -9°C. Skies will remain mostly cloudy tonight as temperatures remain steady near -10°C.

Thursday will bring more cloud to the region with a chance of some more light snow as another weak upper-level disturbance slides across the region. Temperatures will climb to a high near -7°C with light winds. Some clearing will work into the region on Thursday night as temperatures dip to a low near -16°C.

Friday will bring mixed skies to Winnipeg, but the cloud will push back into the region in the afternoon as another Mackenzie clipper begins dropping southeastwards out of the Northwest Territories. Temperatures will reach a high near -11°C before the cloud thickens up in the afternoon.

Models are wavering a bit on the location, but snow will likely push into southwestern Manitoba in the afternoon and then eastwards into the Red River Valley on Friday evening. Temperatures will hover around the -10°C mark on Friday night. Total snowfall amounts are a bit in the air at this point, but around 2 to 5 cm looks probable for Winnipeg.

Long Range Outlook

The weekend looks mild as warmer air pushes eastwards into the province, bringing daytime highs back to around -4°C. Saturday will still bring plenty of cloud, but the sun may make a return on Sunday. At this point, it looks like Monday may be the warmest day with temperatures possibly climbing above freezing before cooler air begins working back into the region with seasonal temperatures returning mid-week.

Winnipeg’s seasonal daytime high is currently -10°C while the seasonal overnight low is -19°C.

Above-seasonal temperatures return to Winnipeg for the weekend at the cost of sunshine with mostly cloudy skies on the way. The prolonged period of cloudy skies will be supported by a convoy of low pressure systems over the next few days that will bring multiple bouts of light snow to the region.

Mild air is rebounding eastwards across the Prairies, however Winnipeg and the Red River Valley won’t quite get into the warm sector, remaining just to its east and under the storm track. While no major systems are on the horizon, Winnipeg will still see plenty of cloud and bouts of non-accumulating light snow.

The first system sliding southeastwards along the storm track will swing through early this morning, sweeping a cold front through the region and ushering in breezy northerly winds of 30 to 40 km/h. The cooler air won’t affect daytime highs too much; Winnipeg should still see temperatures climb to around -4°C midday. Slightly cooler air will push into the region through the afternoon, likely dropping the temperature to around -6°C or so by evening. The passage of the front and slightly cooler air moving in will combine to produce some light snow across the Red River Valley, but we don’t expect it to have much of an impact. No accumulation is expected from it, nor will it adversely impact travel conditions. Heading into Friday night, the Red River Valley will see some clearing, allowing temperatures to plummet in the cold air mass down to a low near -18°C.

Temperatures will rebound fairly quickly on Saturday morning as more cloud cover moves into the region as a warm front pushes eastwards into southern Manitoba. Temperatures will climb back up to a high near -4°C once again under cloudy skies. Winds will pick up out of the south to around 20 km/h in the afternoon, but diminish to 10 to 15 km/h fairly early in the evening. Once again, some non-accumulating light snow is likely in the afternoon as a weak low pressure system slides through the region. Skies will remain mainly cloudy overnight with temperatures remaining steady near -5°C.

On Sunday, Winnipeg will find itself under a stalled frontal boundary under a northwest flow aloft. It looks likely that the city will remain on the warmer side of the front, with cooler air to the northeast and warmer air to the southwest. Winnipeg should see a high near -3°C, but the far southwestern Red River Valley may reach as high as 0°C, while areas colder to the south basin of Lake Winnipeg see highs near -5 or -6°C. A couple very weak disturbances will slide southeastwards over the stalled front through the day, bringing another chance for some non-accumulating light snow through the day.

By late Sunday afternoon into the evening, a more organized low is expected to move into the region, bringing 2 to 4 cm of snow through the evening with temperatures slowly dipping to a low near -11°C.

Long Range Outlook

Next week will begin with a surge of colder air moving into southern Manitoba, but a return to well above-normal temperatures will push back into the region for Wednesday, bringing some light snow with it. The temperature roller coaster looks poised to continue, with colder temperatures then pushing back into the region for the end of the week into the weekend.

Winnipeg’s seasonal daytime high is currently -9°C while the seasonal overnight low is -18°C.
