It will be a windy transition day in Winnipeg today as a warm front pushes across the region. Heading through the weekend, a mild Saturday will give way to unsettled conditions on Sunday.

A warm front will push eastwards across the province today, bringing afternoon cloud and breezy southerlies to Winnipeg. Temperatures will climb to a high near 13 °C with south winds increasing to 40 gusting 60 km/h midday. The city will see a sunny start to the day, but clouds will move in for the afternoon ahead of the warm front. There may be a slight chance of a rain shower in the evening as the front moves through, then skies will clear up for the night. The city will see a low near 5 °C with easing winds.

An upper ridge over the region will bring mild weather to Winnipeg on Saturday. Under partly cloudy skies, the city will see a high near 21 °C with northerly winds up to 20 km/h.

Spring Weather Here to Stay

A broad pattern change will bring Winnipeg milder spring conditions through the next week.

While today won’t be quite as beautiful as Tuesday was, the city will enjoy a great start to the day. Under mixed skies temperatures will quickly climb to a high near 15 °C with light winds. Winnipeg will find itself close to a SW–NE frontal boundary that will slide eastwards in the afternoon. By late-afternoon, moderate northerly winds of 30–40 km/h will push cooler temperatures into the region. The frontal passage will bring cloudier skies with a few showers late in the day into the evening hours.

Cooler temperatures will push in overnight with diminishing winds. Skies will clear out with a low near -3 °C.

The cool temperatures won’t stick around, though. On Thursday, temperatures will quickly rebound back to a high near 12 °C. The city will see plenty of sunshine with partly cloudy skies and winds will be light much of the day. Northwest winds will pick up to around 20 km/h this evening as an area of high pressure moves in. Temperatures will dip to a low near -1 °C overnight with clear skies.

A warm front will move into Manitoba on Friday, bringing windy conditions to the Red River Valley and much warmer conditions to the southwest corner of the province.

Friday will start off sunny, but an approaching warm front will bring clouds for the afternoon. Temperatures will climb quickly through the morning to a high near 16 °C. Southerly winds ahead of the front will strengthen into the 30–40 km/h range for the afternoon. This warm front will support some rain as it pushes east, but it will stay well north of the Red River Valley. The rain is forecast mainly for central and northern Manitoba and it should stay dry this far south.

The clouds will break up on Friday night with gradually easing winds and a mild low near 6 °C.

Long Range Outlook

Winnipeg’s weekend looks great with plenty of sunshine and highs in the mid- to upper-teens. The seasonal temperatures will continue into the start of next week, but a few disturbances moving through on Tuesday/Wednesday are forecast to bring more cloud and a chance of showers to the region.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 2 °C.

Spring Warmth Returns to Winnipeg

Brad Leave a comment

Temperatures will warm in Winnipeg over the coming days as milder air spread across the southern Prairies.

A strong upper-level flow will keep plenty of cloud cover over Winnipeg today. The cloudy conditions will keep things a bit cooler with a high near 12 °C. Winds will stay light out of the southeast through the day. The cloud will move out of the region tonight, leaving clear skies by Tuesday morning with a low near + 3°C.

On Tuesday, a dry trough of low pressure will move in, bringing with it a push of warmer air. Highs will climb into the upper teens under sunny skies with light winds. The cooler air will encroach on the region Tuesday night with temperatures dipping back to a low near +2 °C.

As long as winds are able to turn southerly, Winnipeg will see mild temperatures on Wednesday.

The cooler weather will be temporarily pushed northwards on Wednesday as a compact low pushes into the region from Saskatchewan. Winds will increase out of the south into the 20–30 km/h range with temperatures climbing close to 20 °C. The day will start off sunny, but the cloud will build into the region through the afternoon. The one caveat to highs will be that this system stays far enough north to bring a southerly flow to Winnipeg. If it slumps further south and Winnipeg’s winds stay light or northerly, then temperatures will likely only reach the low teens.

A cold front will sweep through on Wednesday night, bringing breezy northerly winds, cloudy skies, and a chance of showers or flurries. Temperatures will head to a low near the freezing mark.

Long Range Outlook

A ridge of high pressure will bring near-seasonal temperatures to the region on Thursday and Friday. Heading into the weekend, warmer weather is forecast to return, shifting the general weather pattern into seasonal mildness. Daytime highs right into next week are forecast to generally sit in the 15–20 °C range with overnight lows of 4–8 °C. The region should see plenty of sun, but a couple passing systems may bring some showers to the region later in the weekend into the beginning of next week.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 2 °C.
