Seasonably Mild Conditions Return to Winnipeg

Brad Leave a comment

Winnipeg will see temperatures once again climb slightly above seasonal values over the next couple days.

A low pressure system advancing across the Prairies will send temperatures back above freezing in Winnipeg. With plenty of sunshine today, southerly winds will increase into the 30–40 km/h range. The breezy southerlies mark the arrival of a warm air mass, though, and the city should see a near-seasonal high around 0 °C. Some cloud cover will push into the region on Friday night with temperatures heading to a low near -5 °C.

Saturday will bring mostly cloudy skies to Winnipeg as a low pressure system crosses the province. The wind will ease in the morning as the low arrives and temperatures will climb to a high near +2 °C. The low will push out of the region on Saturday evening, ushering in northwest winds of 30–40 km/h with a good chance of some flurries through the night. Temperatures will dip to a low near -6 °C.

A low pressure system crossing Manitoba will bring above-freezing high temperatures back to the Winnipeg region on Saturday.

The breezy northwest winds will persist through much of Sunday, keeping temperatures a bit cooler with a high near -3 °C. Skies will stay mostly cloudy through the morning, but a bit of afternoon sunshine seems likely. While the broader area of flurries will move off, Winnipeg will continue to see a chance of lake-effect flurries until the winds ease off in the evening. The city should see mixed skies on Sunday night with temperatures dipping to a low near -10 °C.

Long Range Outlook

Next week looks to bring variable cloudiness to Winnipeg with his in the -5 to -2 °C range. No notable snowfall events are in the forecast.

Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -9 °C.

More Snow on the Way

Winnipeg will see another batch of light snow beginning later today as a low pressure system pushes across the region.

It’s a clear but cool start to the day in Winnipeg with temperatures in the mid-minus teens. Temperatures will gradually climb through the morning, then pop up to around -2 °C as cloud cover moves into the region. The city might see occasional light snow as the cloud moves in, but a more organized area of snow will push into the region early this evening. The snow will continue through the night as temperatures dip to a low near -7 °C.

Light snow will continue through much of tomorrow as a northwest wind ushers in a cooler air mass and lake-effect flurries from Lake Manitoba follow the broader area of snow. By the time it tapers off later in the day, Winnipeg should see 3–6 cm of new snow from this system. Those northwest winds near 20 km/h will keep things cool with temperature barely recovering to a high near -6 °C. Clearing should push into the region on Thursday night with temperatures dipping to a low near -12 °C.

Light snow will spread across southern Manitoba later today with a west-east swath forecast to receive 2–5 cm.

The region will see partly cloudy skies on Friday with temperatures rebounding nicely. Winnipeg’s high should reach around -1 °C and dip to only -5 °C on Friday night as more cloud cover moves in.

Long Range Outlook

Another low pressure complex consisting of a low ejecting northeastwards out of the American Plains combined with an upper-level disturbance crossing the Prairies will bring cloud and snow to the region this weekend. Temperatures will be mild with highs near the freezing mark, but light snow will likely begin again on Saturday night and continue on Sunday. Another 4–8 cm of snow may be possible with this system as it moves through.

Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -9 °C.

Cooler Weather Ahead

A much cooler air mass building across the Prairies in the wake of yesterday’s Colorado Low will push across southern Manitoba today.

Winnipeg will see breezy westerly winds near 30 gusting 50 km/h today that will usher in cooler temperatures. As the day goes on, skies will cloud over and temperatures will dip to around -4 °C by the evening. Skies will stay on the cloudier side tonight as the wind drops off and temperatures head to a low near -9 °C.

On Tuesday, Winnipeg will see some sunny breaks as temperatures climb back to a high near -4 °C. The cloud cover should clear out by evening leaving Winnipeg with just a few clouds overnight and a low near -13 °C.

A cooler air mass in Manitoba will send overnight lows into the -10 to -20 °C range on Tuesday night.

A weak disturbance will move towards the region on Wednesday, pushing cloud back into the Red River Valley. Temperatures will climb to a high near -1 °C. The city will see a chance of light snow heading into Wednesday night, but no notable accumulations are expected. Temperatures will head to a low near -11 °C.

Long Range Outlook

Cooler weather will stick around for Thursday and Friday as another Arctic ridge moves across the region. Some lake-effect snow will be possible on Thursday in the wake of the disturbance moving through. Some milder weather is possible on the weekend with highs potentially climbing back above the freezing mark.

Today’s seasonal daytime high in Winnipeg is 1 °C while the seasonal overnight low is -7 °C.

Colorado Low Brings Cloudy, Mild Weather to Winnipeg

Brad Leave a comment

Winnipeg’s temperatures will continue above seasonal values as a Colorado Low pushes warmer air northwards. This storm system will bring blizzard conditions with 30 to 50 cm of snow across parts of southern Saskatchewan into central Manitoba as well as a swath of rain and freezing rain. Winnipeg will avoid the worst of it with comparatively pleasant conditions.

Today will mark the transition from the mild, dry Pacific flow of the past few days towards a developing Colorado Low. Winnipeg will see northerly winds in the 20–30 km/h range today. Those winds will keep things cooler with a high near 5 °C under mixed skies. The winds will ease a bit tonight as they shift to the east under cloudy skies. Temperatures should dip to a low near 0 °C.

On Saturday, the storm system will be gathering strength south of the border and supporting a blanket of cloud cover across southern Manitoba. Temperatures should reach a high near 7 °C with easterly winds at 15–25 km/h. The cloud cover and a push of warmer air from the Colorado Low will keep temperatures mild on Saturday night with a low near +3 °C.

A potent Colorado Low will bring winter storm conditions to parts of southern Saskatchewan and Manitoba Sunday into Monday as it spreads heavy snow, ice pellets, freezing rain, and rain across the region.

Sunday will start with a warm front pushing northwards through the Red River Valley. It will bring some drizzle or light rain as it moves through, with mild temperatures afterwards. Winnipeg should see a high near 12 °C but could end up ±2–3 °C depending on the exact low track. A cold front will sweep through on Sunday evening, bringing another chance of showers. Winds will sift to the west overnight as temperatures head to a low near -1 °C.

Long Range Outlook

Much cooler air will push into the region behind this system, triggering more lake-effect precipitation off the Manitoba Lakes on Monday. Winnipeg may end up seeing some flurries through the day as the winds gradually taper off. Things should settle down for Tuesday and the rest of the week, but highs will likely hover just below freezing.

The long-range forecast looks fairly dry with near-seasonal temperatures.

Today’s seasonal daytime high in Winnipeg is 2 °C while the seasonal overnight low is -7 °C.
