Warming Up in Winnipeg

Brad Leave a comment

The weather is going to warm up in Winnipeg this week as an upper ridge builds across the Prairies.

Despite the cold start to the day, today will be a pleasant change from the weather of the past few days in Winnipeg. With the worst of the Arctic ridge to the east, the city will see temperatures climb to a high near 7 °C under sunny skies. Winds won’t be too much of an issue, either, staying light out of the south. Weak ridging will stay over the region tonight which, combined with the light southerly wind, will allow temperatures to fall back to a low near -6 °C.

On Thursday, some warmer air will begin pushing towards Manitoba as an upper ridge builds eastwards. This will bring a few clouds back along with southerly winds of 20–30 km/h. Temperatures will climb to a high near 8 °C in the city. More cloud will push in overnight as a low pressure system begins moving eastwards out of Alberta. With that cloud will come more warm air and southerly winds up to around 30 km/h. This combination of cloud and wind will keep the overnight lows seasonally mild at around +2 °C.

Mild Pacific air will sweep across the Prairies over the remainder of the week.

Friday will bring mostly cloudy skies to the region as a low pressure system crosses the province. The southerly winds will gradually weaken through the day as a trough moves into the Red River Valley. Temperatures will be held back a bit by the cloud cover, but the area should still see highs near 9 or 10 °C. There may be a slight chance of rain showers on Friday evening, but much of the precipitation associated with this system should be weakening as the trough advances eastwards. Temperatures will stay mild on Friday night as the trough passes and winds shift westerly. Winnipeg will see a low near +3 °C.

Long Range Outlook

The seasonally warm weather will stick around for the weekend with highs climbing into the low teens. Overnight lows should stay above freezing through the weekend. A change in the weather looks to arrive next Wednesday when a system moving through the Prairies brings several days of unsettled conditions as it sweeps the Arctic front back south across the region. Near-seasonal temperatures should return in the second half of next week.

Today’s seasonal daytime high in Winnipeg is 3 °C while the seasonal overnight low is -6 °C.

Cool Start To The Work Week

Brad Leave a comment

November is off to a seasonably cool start as highs in the low single digits send cloud cover streaming off the Manitoba Lakes.

A brisk northwesterly wind will keep temperatures cool and skies cloudier in Winnipeg. The city will see temperatures climb only to around 3 °C today with mixed skies as low cloud streams southwards off the Manitoba Lakes. The lakes are also producing some rain showers/snow flurries, but the winds should keep that activity out of the city. Breezy northwest winds of 30 gusting 50 km/h will pick up late morning and make for a rather chilly afternoon.

The winds will ease this evening as they shift a bit more westerly. This change in direction may end up bringing a few snow flurries into the city from Lake Manitoba overnight. Temperatures will dip to a low near -3 °C with cloudier skies.

An Arctic high will bring cold temperatures to the southern Prairies on Wednesday morning.

On Tuesday, the wind will continue to shift westerly and ease as an Arctic ridge slumps into the region. This will bring partly cloudy skies to the city with a high around 2 °C. Skies will clear out on Tuesday night, allowing temperatures to plummet to one of the coldest nights of the season. Lows will dip to around -9 °C.

Winnipeg will see sunny skies on Wednesday with temperatures recovering to around +4 °C. It will be a nice day with light winds. Temperatures will dip back down towards -6 °C or so on Wednesday night.

Long Range Outlook

The second half of the week will see a collapse of the upper low sitting over NW Ontario while an upper ridge builds across the Prairies. This will bring a new push of mild Pacific air into the region. Daytime highs will climb back towards the 10 °C mark by the end of the week. Conditions should stay dry until cooler air begins pushing back into the region sometime in the middle of next week.

Today’s seasonal daytime high in Winnipeg is 3 °C while the seasonal overnight low is -6 °C.

Mild Friday Gives Way to Late Fall Chill

Warmer weather will stick around for one more day in Winnipeg before a major pattern change brings seasonal conditions back to the region.

Temperatures will continue to climb well above seasonal averages in Winnipeg today. Under partly cloudy skies, southerly winds up to 30 gusting 50 km/h will push highs up to around 11 °C. A low pressure system tracking across the Prairies will push cloud cover into the region tonight as temperatures dip to a low near 7 °C.

The pattern change begins on Saturday as the aforementioned low crosses the province. Winnipeg will see cloudy skies as winds shift northwesterly through the day. Those winds will strengthen up to 40 gusting 60 km/h in the afternoon. This system will bring a chance of showers to the region, but the bulk of precipitation will fall to the north. Temperatures will hover around the 7 °C mark through the day, then drop quickly in evening as colder air begins filtering southwards into the region. Temperatures will dip to low around the freezing mark with northwest winds of 20–30 km/h.

A low pressure system will spread rain across potions of southern Manitoba on Saturday.

In the wake of the low, the cool air and northwesterly winds will generate quite a bit of low cloud and precipitation that streams off the Manitoba Lakes. This should keep skies mostly cloudy in Winnipeg on Sunday, and depending on the exact wind directions, the city may end up seeing some snow flurries or rain showers through the day. Temperatures will slowly rebound to a high around 4 °C with breezy northwest winds near 30 gusting 50 km/h.

The winds will finally ease on Sunday night as temperatures dip to a low near -1 °C.

Long Range Outlook

Cloudier conditions will continue through the first half of next week as cool temperatures and northwest winds continue to produce cloud off the Manitoba Lakes. With the air mass over the region continuing to gradually cool, the chance for rain showers or snow flurries will likely continue through the first part of the week.

Conditions will settle for the second half of the week as winds shift westerly, but temperatures will stay near or slightly below seasonal values for the rest of the week.

Today’s seasonal daytime high in Winnipeg is 6 °C while the seasonal overnight low is -4 °C.

Mild Weather Continues Despite Unsettled Wednesday

Brad Leave a comment

Winnipeg will continue to see seasonably mild temperatures even as a disturbance moves through the province today.

It’s back to cloudy skies in the city today with rain lifting northwards out of the Dakotas. Period of rain will begin later this morning in Winnipeg with 5–10 mm possible by the end of the day. Heavier rain will fall to the east with 10–20 mm likely over the eastern Red River Valley into the southeastern corner of the province. Despite the rain, it will be seasonably warm today with a high near 9 °C. The breezy southeasterly winds in the area this morning will diminish through the day.

The rain will shift off to the east tonight, but skies will stay cloudy for the rest of the night. Temperatures will dip to a low near 4 °C.

Rain will spread through much of eastern Manitoba over the next 24 hours with many areas seeing at least 5–10 mm.

Thursday will continue to be seasonably warm in Winnipeg. Temperature swill climb back to around 11 °C with northwest winds near 20 km/h. Skies will be cloudy for much of the day, but some clearing should work its way in through the afternoon. Skies should completely clear out in the evening as a ridge of high pressure moves over the region. Temperatures will dip below the freezing mark on Thursday night.

And finally, to wrap up the work week, Friday will bring beautiful late-October weather to the area. With plenty of sunshine temperatures will climb to a high near 12 °C. Winds will be breezy out of the south at 30–40 km/h, though. A few clouds will begin working into the region in the afternoon as the next low pressure system begins its approach.

Cloudier skies will move in for Friday night and Winnipeg will see a chance of showers as the low crosses the province. Temperatures will once again stay mild with a low near 5 °C.

Long Range Outlook

Behind Friday’s low, Arctic air will flood across the Prairies and usher seasonal to below-seasonal temperatures into the region. Breezy northwest winds will send temperatures into the low single digits by the end of the weekend. The surge of colder air will generate a lot of lake-effect precipitation — both rain and snow — that will affect the region for several days. The return to cooler conditions looks to continue through the rest of next week.

Today’s seasonal daytime high in Winnipeg is 6 °C while the seasonal overnight low is -3 °C.
