Warmer, Windy Weather Ahead

Brad

Winnipeg will see warm and windy weather this weekend with a chance of seeing the sun again!

A disturbance crossing Manitoba today will start bringing drier air into the province and help clear out some cloud. In the Red River Valley, southerly winds will pick up into the 20 to 30 km/h range this afternoon, but the clouds will linger. There will continue to be a chance for freezing drizzle or flurries as temperatures head to a high near -3°C. A trough moving through this evening will usher in westerly winds that will start to break up the cloud cover. Temperatures will dip to a low near -7°C as winds ease.

Saturday will mark the beginning of Winnipeg’s windy weekend as a warm front pushes into the region. Winds will pick up out of the south again to 30 gusting 50 km/h with more cloud than sun. Temperatures will climb towards 0°C through the day, then up above freezing in the evening as winds shift to the southwest. Skies will stay mixed overnight with temperatures dipping back below freezing for Sunday morning.

A warm front will push across the Red River Valley on Saturday evening, ushering in above-freezing temperatures.

A cold front will slump southwards through the Red River Valley on Sunday, bringing more cloud into the region and strengthening west-northwest winds. The Red River Valley will see winds strengthen to 30 gusting 50 km/h except for the western escarpment region where gusts up to 60 km/h will be likely. The organized snow associated with this system will likely stay north of Winnipeg, crossing through the southern Interlake.

The organized snowfall with this system will cross through the southern Interlake, leaving Winnipeg with a chance of flurries as the cold front slumps southwards.

The city will likely see mixed skies through the day with a chance of flurries. There could be a chance of patchy freezing rain, but it’s too early to say with any certainty. Winds will gradually taper off on Sunday night as skies clear with temperatures dipping to a low near -13°C.

Long Range Outlook

Temperatures return towards seasonal values to start next week as a ridge of high pressure builds into the region. The city will finally see some sunshine through the first half of the week with little cloud or snow expected. More cloud is forecast to move in through the second half of the week as warmer temperatures return.

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

Cloudy, Seasonably Mild Conditions Continue

Brad

Cloudy and seasonably mild conditions continue in Winnipeg this week.

Little change in the weather lies ahead for Winnipeg as the upper air pattern stays stagnant. Broad upper ridging is bringing seasonably mild conditions to the region, but has also trapped a huge area of low cloud over the eastern Prairies. As a result, the weather will be surprisingly consistent over the coming days.

Winnipeg will see daytime highs in the -6 to -8°C range over the next few days with overnight lows dipping down into the minus teens. Winds will stay light through the next several days. With all the cloud stuck in the region, some flurries will be possible, particularly in the evening and overnight hours when the temperatures dip a bit.

Long Range Outlook

More of the same is on tap for Thursday, but by Friday the pattern begins to change and the region will transition into a more unsettled pattern. The region will still be dealing with plenty of cloud, but a bit of sun will be possible heading into the weekend. With several disturbances expected to track through the region Friday through Tuesday, there’s also a good chance of seeing some accumulating snow. Right now, the best chances for snow look to be Thursday night, Friday night, and Sunday night into Monday.

Cooler weather is forecast to push back into the region next week.

Today’s seasonal daytime high in Winnipeg is -12°C while the seasonal overnight low is -23°C.

Mild Friday Followed by Winter Storm With Snow, Blowing Snow

Brad

A developing winter storm system will bring mild temperatures today followed by snow, blowing snow, and colder temperatures on Saturday.

Winnipeg will see mostly cloudy conditions today as temperatures climb to a seasonably warm -8°C. The warmer weather is moving into the region ahead of a potent low pressure system set to track across the Northern Plains later today. Much of the day will bring winds out of the southeast near 30 gusting 50 km/h, but they will diminish through the afternoon as a trough of low pressure moves into the Red River Valley.

Light snow will move into the region in the afternoon, then intensify through the evening and persist overnight. The wind will pick back up out of the northwest overnight to 30 gusting 50 km/h, combining with the snow to produce areas of reduced visibility in blowing snow. Winnipeg will see close to 10 cm of snow by Saturday morning with higher amounts expected to the southeast.

Moderate to heavy snow will develop over southern Manitoba on Friday evening.

Winnipeg will see temperatures remain steady near -17°C on Saturday with light snow continuing through much of the day. The wind will strengthen even more to 40 gusting 60 km/h, producing widespread blowing snow through the Red River Valley. Localized blizzard conditions may even develop, particularly through the western Red River Valley. The region will see about 2 cm of additional snow through the day. Winds will ease slightly to 30 gusting 50 km/h on Saturday night, bringing some improvement to the blowing snow across the region. Temperatures will dip to a low near -20°C on Saturday night.

Moderate to strong northwest winds will be in place over southern Manitoba on Saturday.

Everything will move out of the region on Sunday with diminishing winds and clearing skies. Temperatures will climb to a high near -16°C. Winds will shift to the west through the day as an Arctic high passes by to the southwest. Skies should be clear on Sunday night with a low near -26°C.

Long Range Outlook

For those tired of the cold, the long-range forecast is looking pretty good. Cooler weather will stick around for Monday, but then a large-scale pattern shift will allow milder Pacific air to spread across the Prairies. Much of next week should see daytime highs in the -5 to -10°C range with overnight lows dipping into the minus teens. No major snow events are in the forecast. So if you’re cold adverse, just make it through one more cold snap and you’ll have plenty to look forward to!

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -24°C.

Progressive Pattern Brings Mid-Week Cold Snap Followed Up By Mild Friday, More Snow

Brad Leave a comment

Winnipeg will see bitter cold settle over the region for the next couple days, but milder temperatures will quickly move back into the region alongside snow on Friday.

Cold air will continue to build into Winnipeg today with highs climbing to a seasonably cold -19°C. Winnipeg and area will see mostly cloudy skies through the day with some light snow likely. By the evening, around 2 to 4 cm of snow will have fallen in Winnipeg with amounts climbing closer to 5 cm along the International border. Winds will pick up to around 20 km/h this morning and then diminish this evening. A potent Arctic high will continue to push into Manitoba from the west tonight, sending temperatures plummeting to a low near -30°C with clearing skies.

Thursday will be a cold day across the region as that Arctic high slides across the region. Temperatures will top out at just -23°C with light winds and sunny skies. Then on Thursday night, the next low pressure system will begin forming over the southern Prairies and Northern Plains. This system will develop as a low pressure centre crossing the Dakotas with a broad inverted trough extending northwards into southern Manitoba. As it approaches on Thursday night, winds will pick up out of the southeast to around 20 km/h. Cloud cover will spread into the region through the night with temperatures rising to around -17°C by Friday morning.

On Friday, milder temperatures will spread into the Red River Valley as the inverted trough slides through. Winnipeg will see a high near -8°C with a southeast wind continuing at 20 to 30 km/h. More snow will develop over the region on Friday afternoon and continue through the night.

Long Range Outlook

The snow will taper off on Saturday with more seasonal temperatures returning to the region. Sunshine will return for Sunday and the start of next week as temperatures dip with highs dropping into the low minus teens. The cold will be short-lived, though, with near-seasonal temperatures expected to return mid-week.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -24°C.
