Brad Leave a comment

It will be a warm week in Winnipeg with seasonably warm temperatures continuing.

RDPS 2m Temperature Forecast valid 18Z Thursday February 22, 2024
Temperatures will climb back above freezing on Thursday, but a strong cold front will move through later in the day.

Sorry that we’re a day late, but fortunately, the weather’s a broken record these days and we didn’t miss much. The weather through the rest of the work week will be driven by a low pressure system moving through northern Manitoba over the next 24 to 48 hours. As it moves into the province today, more warm air will spread into southern Manitoba. This will bring cloudier skies to Winnipeg and area as temperatures climb to a high close to the freezing mark this afternoon. The cloud cover will break up tonight as westerly winds pick up and temperatures fall to a low in the -10 to -5 °C range.

On Thursday, with Winnipeg firmly in the warm sector of this system temperatures will quickly climb to a high just above freezing before a cold front sweeps through later in the afternoon. The cold front will bring some cloud and a chance of flurries to the region as it moves through, along with northerly winds to around 30 gusting 50 km/h. Skies will clear quickly behind the front as an Arctic high drops southwards through the province. Temperatures will head to a low in the -20 to -15 °C range with light winds on Thursday night.

For Friday, the region will see near-seasonal temperatures with a high near -7 °C under mainly sunny skies. Southerly winds will strengthen through the day in the return flow from the departing high. Another low pressure system tracking through the north will be pushing a warm front eastwards into the province through the day. By Friday evening, the warm front will likely be draped through western Manitoba; it will continue to push eastwards through the night, bringing more cloud to the Red River Valley but keeping overnight lows mild near -10 °C.

Long Range Outlook

Winnipeg will move into the warm sector of this second low pressure system on Saturday. The warmer air mass should combine with moderate westerly winds to help send daytime highs well above freezing; Winnipeg will likely see temperatures climb into the 5 to 10 °C range on Saturday afternoon.

The warmest air will move out of the region on Saturday night, but it will stay mild across the region. Sunday should bring daytime highs closer to 0 °C to the region.

Next week wills tart warm, but a strong cold front is forecast to move through on Tuesday. This would usher an Arctic air mass back into the Prairies and send temperatures tack to below-seasonal values for a couple days. That said, the cold snap is expected to be short with milder weather returning by the end of the week.

Today’s seasonal daytime high in Winnipeg is -7 °C while the seasonal overnight low is -17 °C.

Warmer Weather Returns Quickly to Winnipeg

It’s a cold start to the day in Winnipeg, but the first cold night marks the end of this cold snap; warmer weather is surging back across the Prairies.

RDPS 2m Temperature Forecast valid 21Z Saturday February 17, 2024
Warmer weather will spread across southern Manitoba on Saturday.

The cold weather this morning will break quickly as westerly winds move into the region with a warm front pushing through. Temperatures will warm from the mid-minus 20s this morning to an afternoon high near -10 °C. Westerly winds will pick up through the day to around 30 km/h in Winnipeg. The sun will make an appearance this morning, but skies will cloud over through the day.

The winds will continue through the night with temperatures near -10 °C. There will be a chance of flurries overnight.

Saturday will bring cloudy skies to Winnipeg with a few sunny breaks possible in the afternoon. Behind the warm front, daytime highs will climb into the -5 to 0 °C range with breezy westerly winds up to 40 km/h.   Temperatures will then dip to a low near -10 °C under partly cloudy skies on Saturday night.

Light northerly winds will continue on Sunday with a cooler high than Saturday, topping out near -5 °C in the afternoon. Winnipeg should see plenty of sunshine, though, which will be a nice change from the recent warmth. It will be another cool night on Sunday night as a cold front slumps through southern Manitoba. Overnight lows will likely dip into the -20 to -15 °C range with mainly clear skies.

Long Range Outlook

An upper ridge will continue to build across the Prairies next week, keeping temperatures near to slightly above-normal through the first half of the week. A cold front will begin to slump southwards mid-week, bringing a chance of snow to the region followed by cooler temperatures to end the week.

The pattern after that is uncertain, but it looks like the region could be in for near-seasonal temperatures with more frequent chances for snow heading through the weekend and into next week.

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

Light Snow Leads to Brief Cold Snap

A disturbance passing through southern Manitoba later today will bring light snow followed by moderate northwest winds. Colder air will slump into the region behind it for the end of the work week, but temperatures will rebound quickly through the weekend.

RDPS 24hr. Snowfall Forecast (10:1 SLR) valid 12Z Wednesday February 14, 2024
A low pressure system will leave a swath of fresh snow across southern Manitoba on Tuesday.

Winnipeg will sit under mainly cloudy skies today with southerly winds picking up to around 30 km/h ahead of a low pressure system moving in from the west. Temperatures will be mild with highs near -4 °C this afternoon. Light snow will move across southwest Manitoba today and reach Winnipeg by mid- to late-afternoon.

The snow will continue eastwards through the evening, tapering off to flurries overnight with around 2–3 cm of fresh snow left behind. Temperatures will dip to lows in the -10 to -5 °C range across the Red River Valley tonight.

It will be pleasant on Wednesday with highs again near -5 °C and westerly winds in the 20 to 30 km/h range. With that warmth will come more cloudy skies, though. A cold front will sweep through the region later Wednesday, bringing breezy northwest winds and cooling temperatures. Skies will likely clear out on Wednesday night, letting temperatures drop to a low in the mid-minus teens.

Thursday will finally bring sunshine to the region with northwest winds of 20 to 30 km/h and a high in the -15 to -10 °C range. Unfortunately, those winds will make it feel like it’s in the -20s. An Arctic high will continue to slump southwards through the Prairies through Thursday night; as it drops south, the winds will ease in southern Manitoba and temperatures will head to a low likely near -25 °C.

Long Range Outlook

Southern Manitoba will be under the grip of the Arctic high on Friday. The region will see plenty of sunshine with highs that struggle to climb into the -20 to -15 °C range.

The axis of coldest air will then shift off to the east for the weekend. Temperatures will return to near-seasonal values with breezy westerly winds on Saturday. The near-seasonal temperatures should persist into next week, then likely be followed with another surge of Pacific air that will send temperatures back towards freezing.

Fortunately, it looks like the region should see plenty of sun this weekend which will be a welcome change from the copious amounts of cloud cover the region has seen over the last while!

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -19 °C.

Snow Tapers off With a Cooler Weekend Ahead

Lingering flurries will taper off across southern Manitoba today as the Colorado Low shifts off to the east. Behind it, northerly winds will diminish as cooler temperatures settle into the region.

RDPS 2m Temperature Forecast valid 15Z Sunday February 11, 2024
Although it won’t be particularly cold for early February, the weekend will bring cooler temperatures than the region has seen recently.

It will be the most wintery day seen in weeks across southern Manitoba today as snow tapers off and the region is left with northerly winds of 30 to 40 km/h. There may be blowing snow in western Manitoba, but the recent warmth and limited new snow in the Red River Valley should prevent it from being much of an issue here. Notable will be how much cooler it will be in Winnipeg than recently. Despite that, temperatures will stay above normal values across the region. Winnipeg’s daytime high should reach around -8 °C today and mainly cloudy skies will keep things mild tonight with a lows dipping into the -15 to -10 °C range.

Saturday will bring mostly cloudy skies to the region as an upper trough swings into Manitoba. Highs will bounce back to around -5 °C with light northwest winds. Temperatures will dip back to around -10 °C on Saturday night under cloudy skies. There will be a chance of light snow overnight as the upper trough moves through the region.

Winnipeg might see sunshine on Sunday as light southwest winds develop across the region. Daytime highs should reach back into the -5 to 0 °C range as warming moves eastwards across the Prairies with a building upper ridge. Temperatures will dip back down into the -10 to -5 °C range on Sunday night with variable cloudiness.

Long Range Outlook

The first half of next week will bring variable cloudiness to southern Manitoba with northerly winds and daytime highs in the -5 to 0 °C range. A cold front will slump into the region in the second half of the week, bringing near-seasonal temperatures as highs slump towards -10 °C along with a chance of flurries.

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -20 °C.
