Weather Set To Turn Warmer and Wetter

A large-scale pattern shift begins today that will bring warmer weather back to the region, but alongside the reprieve from the unseasonably cool temperatures comes a shift towards several days of unsettled weather.

Today will be a quiet day across the Red River Valley with sunny skies and a high near 15°C. Winds will be light as a ridge of high pressure moves across the region. Tonight will also bring fairly clear skies and a low near 4°C.

Warmer air will begin working into the region on Saturday, bringing with it partly cloudy skies as temperatures climb to a high near 19°C. Winds will pick up out of the east to around 30 km/h as a warm front sets up along the US border. Skies will remain partly cloudy overnight as temperatures dip to a low near 9°C with continued easterly winds at 20-30 km/h.

A warm front will lie along the US border on Saturday, with very warm temperatures just across North Dakota.

Sunday will be the turning point for Winnipeg as the first disturbance moves through the region. Winds will continue out of the southeast near 30 km/h until a cold front moves through sometime mid-day into the afternoon. This cold front will support an area of showers or thunderstorms as it moves through the region. As the front moves across southern Manitoba, skies will cloud up as temperatures climb to a high near 20°C.

The GDPS is forecasting a swath of precipitation extending all the way from central Alberta across Saskatchewan and into southern Manitoba Sunday through Sunday night.

Once the front passes, temperatures will cool a bit as the winds taper off. Expect a low near 6°C on Sunday night with partly cloudy skies.

Long Range

The forecast through the first half of next week shows several disturbances moving through the region, however exactly where and how much rain falls with them is still very uncertain.

Expect plenty of cloud, particularly into the middle of the week. Temperatures will be mild both Monday and Tuesday, however a brief cool-down will likely happen mid-week with highs dropping into the low teens.

Winnipeg’s seasonal daytime high is currently 19°C while the seasonal overnight low is 5°C.

Calm & Cool Conditions Ahead

Winnipeg will see plenty of sunshine through the second half of the work week, but temperatures will remain slightly below seasonal values.

Today will be the cloudiest day of the next few as an area of low cloud brought into the southern Manitoba overnight by a low pressure system in northwestern Ontario gradually moves out of the region. Once the cloud clears through the afternoon and evening, Winnipeg & the Red River Valley will be left with mainly sunny for Thursday and Friday.

A ridge of high pressure building into the region will keep winds northerly and light over the next few days.

A ridge of high pressure will keep temperatures cooler in the eastern Prairies and help much warmer air build into Alberta and parts of southern Saskatchewan

Daytime highs and overnight lows will be fairly constant; expect daytime highs between 14-16°C and overnight lows near 2-4°C through to Friday.

No precipitation is expected.

Long Range

The weekend continues to look pleasant with daytime highs climbing back towards seasonal and more sunny skies.

There are hints of some cloud cover possible on Sunday—perhaps even a chance of a shower—but most guidance suggests another sunny day. Next week will start off with more calm & warm weather.

Winnipeg’s seasonal daytime high is currently 18°C while the seasonal overnight low is 4°C.

Unsettled Monday, Then A Return to Calmer Conditions

Unsettled Monday, Then A Return to Calmer Conditions

Today will be rather unsettled across the Red River Valley as a trough of low pressure moving through the regions supports scattered showers and thunderstorms. After it passes, though, an omega block begins to develop, bringing more settled weather to the region.

Today’s main weather will be two rounds of showers that move through the Red River Valley. The first round will be early this morning, a continuation of showers and thunderstorms that developed in Saskatchewan last night and have pushed eastwards overnight. There is a chance we’ll also see some embedded thunderstorms with this band as it moves through. General morning rainfall will be around 5-10mm in many areas, but due to the convective nature of the precipitation there will be significant variability, with some areas potentially seeing nothing and others seeing higher amounts.

One guess at what the RADAR will look like later this morning as showers move through.

The second wave of showers will develop in the afternoon as a second low pressure centre moves through the region. This band will likely be more focused that the morning activity and primarily impact areas south of the bulk of the morning activity.

Aside from the rain, conditions will be fairly cloudy, although there may be an odd sunny break between the two batches of showers. Temperatures will be mild with a high near 19°C, but winds will be breezy out of the southeast at around 30 km/h. Temperatures will dip down to around 8°C tonight with clearing skies and winds flipping around to the northwest at 10-20 km/h.

Tuesday and Wednesday with both be much sunnier days with north to northwesterly winds. Tuesday will bring a high near 18 or 19°C with temperatures then dropping to a low near 7°C. Wednesday has quite a bit of uncertainty regarding the daytime high. The developing omega block will be pumping warmth across the western Prairies towards Manitoba, but an upper-level low will be moving westwards from Eastern Canada, pushing cooler temperatures into Manitoba from the east and northeast.

This will create a fairly sharp temperature difference somewhere across the southern part of the province, and with a relatively quick change from 19-20°C in the warm air to around 5°C in the cold air. Winnipeg looks to lie in the middle of this zone, with a high likely near 14°C, but a minor shift of this boundary to the north or south would substantially change the expected high temperature.

Long Range

The weather will continue fairly quiet through the remainder of the week with the cooler temperatures mid-week giving way to highs back near 19-20°C for Winnipeg by Friday. The weekend looks mild, but a chance for showers returns to the region on Sunday.

Winnipeg’s seasonal daytime high is currently 18°C while the seasonal overnight low is 4°C.

Summer-Like Weekend Ahead

We got a short forecast for you today: beautiful! Nothing but sunshine and warmth on the way for Winnipeg this weekend.

The weather over the coming days will be a result of the upper-level ridge we talked about on Wednesday, which is bringing sunny and warm weather to the region.

An upper-level ridge will be in place over Manitoba for the coming several days.

Winnipeg and the Red River Valley will see plenty of sunshine over the coming days with daytime highs in the 19-22°C range and overnight lows gradually warming from around 6°C up to 10 or 11°C by Friday night. Winds pick up out of the northeast today to 20-30 km/h, but then diminish for Saturday. Sunday will see a winds pick up out of the southeast once again to 20-30 km/h.

Long Range

The upper-level ridge will collapse on Monday as a shortwave digs into the Prairies, bringing with it a chance for some rain. Temperatures will remain mild with highs near 20°C though.

A large omega block is forecast to develop over the region next week.

Rapidly after Monday’s disturbance, an omega block — named such as the shape of the jet stream inside one resembles the greek letter Ω — will develop, rooted over the Canadian Prairies. While this will bring cooler, wet weather to both the west coast and eastern Canada, it will bring a prolonged stretch of warm and dry weather to southern Manitoba.

Enjoy getting outside in this fantastic spring weather!

Winnipeg’s seasonal daytime high is currently 17°C while the seasonal overnight low is 3°C.
