Gradual Warm-Up Begins

Brad Leave a comment

Winnipeg will finally see temperatures warm back towards seasonal values through the rest of the week as the Arctic grip on the region weakens.

Temperatures in Winnipeg will gradually moderate through the rest of the week, followed by a push of much warmer Pacific air. Today will be the last day of lingering cold as the Arctic ridge hangs back into the region just a bit longer. Winnipeg will see a high near -17 °C and light south winds under mainly sunny skies.

A weak upper-level disturbance will move through the region tonight, bringing some cloud and a few flurries to the Red River Valley. The cloud will help keep temperatures slightly warmer tonight with lows “only” around -22 °C.

Another ridge of high pressure will move across the region on Thursday in the wake of the overnight disturbance. This will bring partly cloudy skies to the region as temperatures climb to a high near -13 °C. Skies will clear out for Thursday night with a low near -25 °C.

Milder Pacific air will start pushing eastwards across the Prairies on Friday.

On Friday, the region should see mainly sunny conditions with temperatures climbing to a high near -12 °C. Temperatures will dip to a low near -17 °C on Friday night, but southerly winds will strengthen into the 20–30 km/h range overnight as a warm front moves towards the region. This front will also push some cloud into the region by Saturday morning.

Long Range Outlook

This weekend will bring a definitive close to the cold snap over the region as mild Pacific air washes over the province. Highs will climb to around -5 °C on Saturday to around 0 °C on Sunday with some breezy south-southwest winds. Some snow is possible on Saturday.

Highs may even climb above freezing for the first few days of next week before returning to near-seasonal values mid-week. A couple chances for snow exist through the first half of next week as a few disturbances slide southeastwards across the Prairies.

Today’s seasonal daytime high in Winnipeg is -8 °C while the seasonal overnight low is -18 °C.

Cooler, Cloudy Weather Ahead

Winnipeg will see plenty of cloud over the coming days as Thursday’s low pressure system clears out and a weaker one arrives.

The city will see mainly cloudy skies today with slight snow tapering off as the influence from yesterday’s low wanes. A cold front will sweep through the region this morning, keeping things windy as temperatures fall towards -9 °C by the end of the afternoon. The winds will taper off in the evening as a ridge slides southeastwards into the Red River Valley. Skies will stay mainly cloudy through the night with a low near -14 °C.

Moderate northerly winds near 40 gusting 60 km/h will gradually taper off through Friday afternoon.

On Saturday, the city will stay under the ridge for most of day with light winds. While a bit of snow is possible, the ridge should keep most of it suppressed through the day. Temperatures will rebound to a high near -6 °C. On Saturday night, a low pressure system will move into northern Manitoba and drag an occluding frontal wave into the province. Winnipeg will see a low near -10 °C with a chance for some light snow overnight.

On Sunday, Winnipeg will see more cloud cover and some light snow as the frontal wave collapses through the region. Temperatures will warm a bit with a high near -4 °C with light northwest winds. Another ridge will push into the region overnight, sending temperatures to a low near -15 °C under mostly cloudy skies.

Long Range Outlook

Near-seasonal temperatures will arrive to start next week with daytime highs finally dipping into the -10 to -15 °C range. A mid-week low pressure system will bring mild conditions and a chance for some more snow to the city, then near-seasonal temperatures will push back into the region with highs dipping into the mid-minus teens.

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

More Warm Weather Ahead

No notable changes to start the week for Winnipeg with more unseasonably mild temperatures ahead. A change in the weather will arrive for Thursday.

The Canadian Prairies will continue to see a zonal flow aloft this week, running along the northern edge of a broad upper-level ridge. This will keep the milder Pacific air coming and give Winnipeg dry, warm weather.

As a result, the city will see daytime highs of -2 to +1 °C over the coming days. Overnight lows will cool slightly over the next couple nights into the -5 to -7 °C range. On Wednesday, a low pressure system moving through the province will bring more cloud and warmth. This system will likely keep temperatures above freezing on Wednesday night.

Winds will stay light over the coming days. On Tuesday, areas along the Red River Valley’s western escarpment will see some breezy downslope winds, but they should ease to light by the central Red River Valley. On Wednesday night, the low moving across the province will strengthen winds in Winnipeg out of the south-southwest to 30 gusting 50 km/h by Thursday morning.

Downslope winds over the western Red River Valley will push temperatures above freezing on Tuesday.

Conditions will stay fairly dry over the coming days. A passing flurry is possible on Tuesday, but the next organized chance for precipitation will be Wednesday night as the low passes. Some rain showers are possible overnight, followed by a freeze early Thursday and more snow and wind.

Long Range Outlook

Thursday looks to be an unpleasant day across the region. Snow will move through the region on Thursday into Thursday night with a total likely near 5 cm. With the snow will come strong northwest winds into the 40–50 km/h range will entrench over the region that will linger into Friday. The combination of temperature falling below freezing on Wednesday night, fresh snow, and strong winds will likely lead to poor travel conditions through Thursday.

The passage of this low will shift Winnipeg into a slightly cooler weather pattern. Temperatures will still stay above seasonal values, but will be a bit more “wintery” than seen lately. Daytime highs are forecast to fall into the -5 to -10 °C range with lows into the minus teens.

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

Quiet, Mild Weekend Ahead

The ship will be staying the course in Winnipeg this weekend with little change to the weather.

Southern Manitoba will see quiet weather this weekend as upper ridging stays over the region into next week. This upper pattern will support a broad area of high pressure across the southern Prairies over the coming days.

Little change in the weather is on on the way this weekend with mild winter temperatures persisting across the southern Prairies.

As a result, Winnipeg will see little change in the weather. The city will see highs near -1 °C and lows in the low minus single digits. Cloud will stick around today as fog in the area slowly lifts, followed by clearing skies on Saturday. Winds will be light today and tomorrow, but pick up out of the south to around 20 km/h on Sunday as the high slumps south of the province.

Long Range Outlook

Warm weather continues into the start of next week with variable cloudiness. Temperatures will begin to cool a bit through the latter half of the week, but still staying above seasonal values. No significant snow is in the forecast.

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