Winnipeg will see seasonably mild conditions over the next several days with an abundance of cloud cover.

Winnipeg will see the light snow that moved into the region yesterday persist for a few more hours this morning before tapering off. Cloudy skies will remain as temperatures climb to a high near +2°C this afternoon. Winds will stay light through the day. Tonight will bring more cloudy skies with temperatures dipping to a low near -3°C.

With a stagnant pattern in place over Winnipeg on Thursday, the city see similar conditions to Wednesday. Under mostly cloudy skies, temperatures will climb to a high near +3°C with light winds. There may be a few clear patches on Thursday night as temperatures dip to a low near -3°C again. Winds will increase to around 15 km/h by Friday morning.

A more organized disturbance will begin working its way towards Winnipeg on Friday as a large Pacific storm system begins pushing inland. Winnipeg will see mostly cloudy skies with a high near +3°C yet again. Winds, however, will be a bit more noticeable out of the east-southeast near 20 km/h. By late in the day, an area of snow will begin spreading across southwestern Manitoba into the Red River Valley. Winnipeg will likely see a couple cm of snow on Friday night as temperatures drop to a low near -2°C.

Long Range Outlook

Looking ahead to the weekend, Winnipeg will see more of the same with cloudy skies, highs near +3°C, and lows dipping just below freezing. Snow should taper off Saturday morning, then a more significant snowfall of 4 to 8 cm is forecast to move into the region on Sunday.

This second batch of snow is forecast to taper off on Sunday night, followed by gradual clearing in the Red River Valley through the first half of next week. Temperatures will remain relatively mild with highs a few degrees above 0°C and lows dipping a few degrees below.

Winnipeg’s seasonal daytime high is currently 1°C while the seasonal overnight low is -9°C.

Cloudy Conditions Continue

Seasonal temperatures will continue in Winnipeg this week, but with plenty of cloud and a bit of light snow.

Winnipeg will remain under cloudy to mostly cloudy skies for the next three days as a train of upper-level disturbances moves through the region. Temperatures will reach a high near -1°C under cloudy skies in Winnipeg today. Some light snow may develop in Winnipeg this afternoon as a weakling upper-level trough moves into Manitoba. The chance for light snow will continue tonight as temperatures dip down to a low near -7°C.

Tuesday will bring more cloudy skies to Winnipeg with a high near 0°C. The Red River Valley will continue to see a chance of light snow as the upper trough exits the province. All snow – if there is any – should taper off on Tuesday night as temperatures head to a low near -7°C.

Temperatures will climb above the freezing mark in Winnipeg on TuesdayWednesday will bring…more cloud to Winnipeg. Light winds over the coming 3 days will do very little to move the extensive area of cloud out of the region. So, under mostly cloudy skies Winnipeg should reach a high near +1 or +2°C. With more cloud around on Wednesday night, temperatures should dip to a low near -7°C yet again.

Long Range Outlook

Little change is forecast through the remainder of the week. Fairly cloudy conditions will remain in place, but temperatures will warm just a tad with highs climbing into the +3 to 5°C range. The weekend continues the cloudy prognosis, with increasing chances for light snow.

Winnipeg’s seasonal daytime high is currently 0°C while the seasonal overnight low is -10°C.

Winnipeg will see variable cloudiness and near-seasonal temperatures through the remainder of the work week.

Winnipeg will see pleasant days ahead despite slightly below-seasonal temperatures. The city will see variable cloudiness today and tomorrow as the last remaining cloud from Monday’s storm system drifts eastwards through the region. No snow is expected. Winnipeg should see high temperatures near -5 or -4°C and overnight lows dipping as cold as -15°C.

A low pressure system will be just west of the Manitoba border by Friday evening

Friday may start with a bit of sunshine, but cloud is forecast to begin moving in early in the day as a low pressure system approaches from Saskatchewan. Winds will pick up out of the southeast to around 20 to 30 km/h. Temperatures will reach a seasonal -3°C for a high, then dip down to about -6°C overnight under cloudy skies. The chance for light snow will increase after midnight as the low moves into Manitoba.

Long Range Outlook

Saturday morning will likely bring a bit of light snow to the region with accumulations of 2 to 3 cm possible. The snow will taper off as the low pressure system passes and winds switch to northwesterly. Mild temperatures will remain in place for Saturday, the near-seasonal temperatures return for Sunday.

Next week is looking fairly dry with a fair amount of sunshine. Temperatures should return to slightly above-seasonal values, with several days above-0°C days possible!

Winnipeg’s seasonal daytime high is currently -3°C while the seasonal overnight low is -13°C.

Snow Tapering Off As Winnipeg Digs Out

Brad Leave a comment

Snow will gradually taper off today as Winnipeg digs out of the biggest snow storm of the 2017/18 winter season.

The long-advertised winter storm has finally moved into the Red River Valley, bringing a variety of winter weather with it. Everything started off yesterday evening as rain and ice pellets moved into Manitoba from North Dakota. As the precipitation intensified, the rain switched over to heavy snow. In some places, notably near Letellier and west of Winnipeg, people got to experience the rare1 phenomenon known as thundersnow. Heavy snow set up along a southeast to northwest band that remained stationary for much of the night. Winnipeg found itself right under that band, and so far has seen as much as 15 to 20 cm of snow, with snow still falling in some parts of the city.

This storm has had significant impact on southern Manitoba. Through Sunday evening, many area highways began to close as the snow piled up and conditions became quite treacherous. As of 6:15 this morning, most major highways still remain closed. Additionally, the wet, heavy snow has resulted in power bumps or outages throughout Winnipeg and the Red River Valley. Manitoba Hydro’s power outage map shows a rather extensive area where the overnight snow has impacted the power grid.

Periods of snow will continue today as it streams northwestwards through the region. At times where Winnipeg may find itself outside the bands of snow moving through, there will be a slight chance of freezing drizzle. In Winnipeg, the snow should taper off by mid-to-late afternoon as drier air begins moving westwards from Ontario. The snow will continue over the western Red River Valley well into the evening, so travellers will still need to give themselves time and drive carefully if heading west once the highways re-open.

Temperatures will continue to be mild today with a high near 0°C. Winds will continue out of the east around 30 gusting to 50 km/h for the rest of the day. The chance for snow will taper off this evening, as will the winds. The clouds will begin to break up sometime after midnight as temperatures head to a low near -12°C.

Tuesday will bring mixed skies with some gradual clearing towards sunnier conditions in the afternoon. Temperatures will be near-seasonal with a high near -5°C. The winds will be lighter too at about 15 km/h out of the northeast. More clouds will move in overnight as the inverted trough that has been anchored near the Saskatchewan/Manitoba border begins shifting eastwards. Expect a low near -14°C on Tuesday night.

Wednesday will bring the inverted trough back through Winnipeg, bringing mostly cloudy skies and a chance of flurries as it moves through. Temperatures will remain similar to Tuesday with a high near -5°C and low overnight near -13°C. Winds will be light as the trough moves through.

Long Range Outlook

The remainder of the work week will bring variable cloudiness with temperatures climbing back towards 0°C for the weekend. A disturbance moving through at the end of the week may bring another batch of snow to Winnipeg. Forecasts currently show the possibility of 2-5 cm Friday night into Saturday morning. After that moves through, the weather looks fairly quiet with mild temperatures.

Dig out, enjoy the winter wonderland, and get ready for slush and puddles by the end of the week!

Winnipeg’s seasonal daytime high is currently -4°C while the seasonal overnight low is -14°C.
