Warm Weather Ahead

Winnipeg will see daytime highs climb above freezing right through the weekend.

A broad upper ridge of the Prairies will bring plenty of sunshine and warmth to Winnipeg over the coming days. Both Friday and Saturday will bring plenty of sun to the city along with highs near 6 °C. The winds will stay light today, but a low pressure system moving from Saskatchewan into northern Manitoba will bring southerly winds of 40 gusting 60 km/h to the Red River Valley on Saturday. Lows will dip to around -6 °C tonight and just below freezing on Saturday night.

Mild temperatures will spread across the Red River Valley on Sunday.

On Sunday, Winnipeg will see mostly cloudy skies as a low and associated trough moves through the province. No notable precipitation will fall over southern Manitoba, but skies should stay mostly cloudy through the day. It will be warm with a high near 8 or 9 °C, but will be a few degrees warmer than that over the western Red River Valley. Winnipeg may climb over that high if the westerly winds arrive earlier in the day or a bit more sunshine materializes. Winds will ease midday into the 20–30 km/h range, then shift westerly as the trough passes.

Winds will ease Sunday night with lows near -2 °C and partly cloudy skies.

Long Range Outlook

Conditions will turn a little more unsettled next week as low pressure system moves out of the Northern Plains into the region. Winnipeg may see some rain or snow on Tuesday, followed by some sun and slightly cooler — but still seasonably mild — temperatures.

Today’s seasonal daytime high in Winnipeg is -4 °C while the seasonal overnight low is -14 °C.

Spring-Like Warmth To Start The Week

A Pacific low will bring breezy westerly winds and temperatures well above freezing to southern Manitoba today.

A Pacific low crossing the province has pushed a warm front through overnight, bringing breezy westerly winds near 30 km/h and a mild air mass to the region. Temperatures will climb to a high near 6 °C this afternoon in Winnipeg with even gustier winds as high as 40 gusting 60 km/h developing. A weak cold front will push through this afternoon, bringing more cloud cover and a chance of a few showers turning to flurries this evening.

The wind will shift northwestwards overnight as it eases and temperatures will dip to a low near -6 °C. Skies will stay partly cloudy.

The southern Prairies will see spring-like warmth today.

On Tuesday, Winnipeg will see mostly cloudy skies as an Alberta Clipper drops from Saskatchewan into the Dakotas. Winnipeg shouldn’t see any snow from this system, but areas over the southwest corner of the province may receive as much as 5–10 cm of snow with amounts diminishing heading eastwards into the Red River Valley. Temperatures will warm back up to a high near -2 °C with a light north wind. The cloud cover will break up a bit on Tuesday night as temperatures dip to around -15 °C.

A ridge will move across the province on Wednesday bringing quiet weather to the region. Temperatures will climb to a high near -8 °C with light northwest winds and mixed skies.

Long Range Outlook

Another strong Pacific low will move across the Prairies in the second half of the week, bringing warm and windy weather back to southern Manitoba on Thursday. Heading into Friday, some rain or snow is possible, followed by a strong cold front on Friday night. Colder temperatures will move back in for the weekend with lows potentially dipping back into the mid-minus twenties. The cold weather will be short-lived, though, with near-freezing highs forecast to return early next week.

Today’s seasonal daytime high in Winnipeg is -6 °C while the seasonal overnight low is -17 °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.
