Unsettled Weather Moving In

Winnipeg will see several days of cloudy, unsettled conditions as an upper low moves through the region.

The Canadian weather models keep all of today’s rain south of Winnipeg.

An upper low moving across the Prairies will drive the weather in the Red River Valley over the coming days. It will support a complex of low pressure systems that amalgamate into a larger single low that stalls out over NW Ontario. As this evolution of the system occurs, it will bring several waves of precipitation to the Winnipeg area.

The first wave of precipitation will move into the region today. Rain will spread northwards out of the Dakotas midday into the Red River Valley and last through the afternoon.

How far north the rain pushes will be a bit of question. It looks likely that much of it will remain just south of Winnipeg, but a brief period of rain is certainly possible through the early afternoon. Some snow will likely mix in with the rain in the evening with periods of a wintery mix lasting through the night. The precipitation will ease on Wednesday morning.

More rain will push in from the east in the afternoon. This wave of precipitation will affect the entire Red River Valley this time, Winnipeg included. The rain should become mixed with snow late in the day, then change over completely to snow overnight. A few flurries will taper off on Thursday morning, but skies will likely stay cloudy through much of the day.

A mix of rain and snow will fall across much of south-central and southeastern Manitoba Wednesday into Thursday morning.

Daytime highs over the next few days will hover around 3 or 4 °C with temperatures back to around freezing overnight. The wind will be quite noticeable over the coming days, though, making for chilly conditions. Moderate easterly winds will shift north overnight, then pick up to strong northwesterlies later Wednesday. These strong northwest winds of 40–50 km/h will persist through Thursday. The wind will finally begin to ease on Thursday night into Friday.

The week will end strong with a high in the 5–10 °C range and more sunshine. Temperatures will dip below freezing both Thursday night and Friday night.

Long Range Outlook

Temperatures will climb back above seasonal values on Saturday with a high near 10 °C. More cloud will move into the area ahead of another major low pressure system crossing the Prairies.

This system may bring some more precipitation to the region Sunday into next week, but there’s quite a bit of uncertainty at this point. Either way, a few days of seasonably warm weather and mixed to cloudier skies will start off the new week.

Today’s seasonal daytime high in Winnipeg is 7 °C while the seasonal overnight low is -5 °C.

Warmer Weather Moves Into Southern Manitoba

Springtime is on the way to southern Manitoba, but will also bring a wintry mix of precipitation on Tuesday evening.

RDPS Forecast Precipitation Type valid 06Z Wednesday March 16, 2022
A mix of rain, freezing rain, and snow will move east across southern Manitoba on Tuesday night.

The the polar vortex retreating into the High Arctic, milder Pacific air has begun to flood across the Prairies. Temperatures climbed above freezing across southern Alberta and Saskatchewan yesterday, and will continue into southern Manitoba today.

Temperatures will warm across southern Manitoba today, but the snowpack will limit highs to within a couple degrees above freezing. An approaching low pressure system will provide more cloud to the region today, followed by precipitation this evening.

Southern Manitoba will see a wintery mix of precipitation tonight. Rain is likely along and south of the Trans-Canada Highway corridor. North of that, freezing rain will fall through the Parkland and southern Interlake areas. And north of that, snow will cross through Swan River and the northern Interlake. Precipitation types will also mix along the boundaries, making for a bit of a mess in some areas.

In Winnipeg, 3–5 mm of rain seems most likely. When combined with the above-zero temperatures, this will work towards beginning to chip away at the snowpack in the area.

The precipitation will move out of the region early Wednesday, leaving behind cloudy skies, light winds, and temperatures hovering a degree or two above freezing. A cool front will sweep through on Wednesday evening bringing a few flurries to the region.

RDPS 2m Temperature Forecast valid 21Z Thursday March 17, 2022
Temperatures will struggle to climb much above 0 °C over the deep snowpack over the south-central and southeastern Prairies.

Mixed to cloudy skies will stick around for the rest of the work week. Daytime highs will climb a couple degrees above freezing while overnight lows dip below.

Long Range Outlook

Warm weather will continue through the weekend with highs above freezing and variable cloudiness. This week should provide conditions favourable for a gradual snowmelt with dew point temperatures largely staying below the freezing mark and temperatures largely hovering just a bit above freezing.

Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -11 °C.

Mid-Week Low Brings Warm Weather To An End

A low pressure system that will move through the region will bring an end to Winnipeg’s stretch of beautiful late-fall weather. Rain, snow, and cooler conditions are on the way.

But first, a couple more pleasant November days lie ahead for the city. Winnipeg will see plenty of sunshine over the next couple days with highs in the 8–10 °C. Winds will be breezy today out of the west at 20–30 km/h, then ease slightly for Tuesday. Overnight lows will dip to around the freezing mark.

On Wednesday, a low pressure system will move from Saskatchewan into southern Manitoba, spreading cloud and rain across the province. Most areas in the Red River Valley should see 5–10 mm of rain through the day. Winds will start out at 20–30 km/h out of the southeast, then ease to light as the low moves over the Red River Valley in the evening. Temperatures will be much cooler with a high near 3 °C.

Much of southern Manitoba will see rain on Wednesday.

Rain may become mixed with snow late in the day, then will change completely over to snow sometime overnight as temperatures drop below freezing.

Long Range Outlook

The seasons will change quickly this year as the region will look a lot more like winter by the end of Thursday. Moderate northerly winds of 30–40 km/h will develop behind the low and continue to usher cooler air into the region. Snow will continue through much of the day on Thursday with 5–10 cm accumulation likely by Thursday evening. Some periods of light snow will likely continue through Friday, and a bit of light snow may be possible with a weak low on Saturday.

Temperatures will hover near seasonal values right through the weekend with highs around the freezing mark. Overnight lows will dip into the mid-minus single digits.

Today’s seasonal daytime high in Winnipeg is +1 °C while the seasonal overnight low is -8 °C.

Mild Weather Continues Despite Unsettled Wednesday

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.

RDPS 24hr. Precipitation Accumulation Forecast valid 12Z Thursday October 28, 2021
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.
