Cool, Cloudy Weather Continues

Winnipeg will continue to see seasonably cool conditions with skies staying on the cloudier side.

The city will see a chance for some early morning light snow as the disturbance that brought snow to the region yesterday pushes off to the east. After that, Winnipeg will see mostly cloudy skies with a few afternoon sunny breaks possible. Temperatures will climb to a high near +2 °C with light west-northwest winds. Skies will cloud back over tonight as another disturbance movs towards the region. Temperatures will head to a low near -5 °C.

Thursday will bring cloudy skies to the city with a chance of light snow. Snow will push into the province from North Dakota as the day progresses; it may reach Winnipeg as far north as Winnipeg, but will mainly impact areas south and southeast. Temperatures will reach a high near +1 °C and winds will pick up out of the north into the 20–30 km/h range.

As those northerly winds pick up, they will support the development of more lake-effect snow from the Manitoba Lakes. The winds are forecast to shift northwesterly overnight, which will rotate the Lake Manitoba band towards Winnipeg. The city will see a chance of flurries overnight as temperatures dip to -5 °C again.

Snow will graze across southern Manitoba on Thursday, followed by the development of more lake-effect flurries.

The cloud cover will finally break up on Friday, but persistent cloud cover form Lake Manitoba will keep skies mixed. The city will continue to see a chance of flurries as west-northwest winds of 20–30 km/h continue to bring a chance of flurries from Lake Manitoba. Temperatures will be a tad cooler with a high near +1 °C. The winds will turn westerly and ease on Friday evening with clearing skies. As long as those skies clear, then temperatures will head to a low near -12 °C.

Long Range Outlook

The weekend will bring a fair amount of sunshine with highs near the freezing mark and overnight lows in the -5 to -10 °C range. In fact…it’s much more of the same right through next week. Highs of -2 to 0 °C and overnight lows in the -5 to -10 °C range with variable cloudiness.

The only thing that could put a wrench in plans is if the lake-effect snow continues off Lake Manitoba into the weekend. If so, it won’t affect temperatures too much but the city could end up seeing some cloudy periods with a chance of light snow as well.

Today’s seasonal daytime high in Winnipeg is 8 °C while the seasonal overnight low is -2 °C.

Continuing Cool With Some Light Snow

Seasonably cool temperatures will continue in Winnipeg through the week with some light snow likely on Tuesday.

A persistent vortex over Hudson Bay continues to push Arctic air southwards across the Prairies. With little forecasted change in the long-wave pattern, below-normal temperatures will be the norm right into next week. Winnipeg will see highs climb just above freezing over the coming few days with overnight lows varying between around -3 or -4 °C and near -10 °C.

Today will bring partly cloudy skies to Winnipeg with a small chance of light snow from passing lake-effect clouds. Skies should clear out tonight as a ridge moves through, allowing temperatures to drop to a low close to -10 °C.

On Tuesday, a disturbance moving into the region will spread cloud into Winnipeg through the day. Light snow will spread through the province, reaching Winnipeg sometime mid- to late-afternoon. The city should see light snow through the night with a few centimetres accumulation possible.

Light snow will spread across southern Manitoba on Tuesday into Wednesday.

The snow will ease up on Wednesday morning, followed by a few sunny breaks through the day.

Long Range Outlook

The city will continue to see variable cloudiness with the occasional chance for some passing light snow. With little change to the long-wave pattern expected in the coming week, don’t expect any significant changes in our day to day weather either.

Today’s seasonal daytime high in Winnipeg is 9 °C while the seasonal overnight low is -2 °C.

Colder Weather Continues with Chance of Light Snow

Winnipeg will continue to see cool temperatures through the weekend, but cloudier conditions will bring a chance of light snow to the city.

Clouds streaming southeastwards off Lake Manitoba will bring Winnipeg mixed to mostly cloudy skies to start the day. These bands of lake-effect cloud will also likely produce a bit of light snow, but other than a dusting that makes the roads a little wet. The snow should taper off midday as a ridge of high pressure moves into the region and the northwest winds begin to ease. A bit of sun is likely this afternoon, but temperatures will stay cool with a high near +2 °C.

Tonight, the region will see increasing cloud cover as a low pressure system moves into the Dakotas. This system will bring some light snow to areas along the international border, but Winnipeg should just see some cloud. Temperatures will dip to a low near -5 °C.

Saturday will start with cloudy conditions across the region with temperatures climbing to a high near +2 °C. As the low pushes eastwards out of the Dakotas, northwest winds will strengthen across the region into the 30–40 km/h range. This will result in bands of lake-effect snow redeveloping sometime later in the day into the evening. Winnipeg will likely see cloud and snow from Lake Manitoba by the evening hours and persisting through the night. Winnipeg shouldn’t see much more than a dusting of snow, but areas northwest of the city could see 1–4 cm by Sunday morning. Temperatures will dip to -5 °C on Saturday night with winds easing.

Flurries from Lake Manitoba will move into Winnipeg by Saturday evening.

Winnipeg will continue to see bands of lake-effect cloud and intermittent light snow on Sunday. Temperatures will climb to a high near +2 °C with west-northwest winds in the 20–30 km/h range. Sunday night should bring partly cloudy skies to the region with temperatures heading to a low near -7 °C.

Long Range Outlook

Long-range forecasts continue to show cool weather for Winnipeg. Daytime highs may moderate into the mid-single digits next Tuesday and Wednesday, but then cooler air pushes back into the region with highs falling to the freezing mark by next Saturday. The region will likely see cloudier conditions next week with the occasional chance of light snow.

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

Cool with Snow to Start, But Spring Arrives Mid-Week

Winnipeg will have a cool and unsettled start to the week, but warmer spring conditions are on the way.

A cold front slumping southwards today will bring cool temperatures and mostly cloudy skies to Winnipeg. Northwest winds up to 30 gusting 50 km/h will keep temperatures to a high of just +3°C. A few flurries will be possible midday through the afternoon as general instability develops over the region. The clouds will clear out this evening with diminishing winds. A ridge of high pressure moving through overnight will send lows down to -10°C by Tuesday morning.

Another low pressure system will slide through the southeastern Prairies on Tuesday. While it will bring mild conditions to southeastern Saskatchewan and southwestern Manitoba, it will be much cooler in the Red River Valley. Highs will again sit near +3°C with breezy south-southeast winds of 30 gusting 50 km/h. Skies will cloud over in the morning as the low pushes into the southwest corner of the province, followed by some light snow through the afternoon hours. The winds will taper off in the evening with some fo the cloud cover breaking up. Temperatures will dip to a low near -2°C.

RDPS Precipitation Type/Rate Forecast valid 06Z Monday April 20, 2020
On Tuesday, a low pressure system will produce a swath of snow that moves from west-central Manitoba southeastwards into the Red River Valley.

Wednesday will mark the beginning of The Turnaround®. A more zonal flow will develop across the Prairies as the west coast upper ridge begins to collapse, allowing milder Pacific air to push eastwards. Winnipeg will see a high near +9°C with mixed skies and light winds. Skies will stay mixed on Wednesday night with a low near +2°C.

Long Range Outlook

The rest of the week finally looks to bring pleasant spring weather. With partly cloudy to mixed skies, Winnipeg will see several days of highs in the mid-teens with light winds. There may be a chance of showers (or perhaps even thunderstorms) in the second half of the week, currently looking like possibly on Wednesday night into Thursday morning. Even warmer weather looks likely for the weekend with highs climbing into the upper teens.

Today’s seasonal daytime high in Winnipeg is 12°C while the seasonal overnight low is 0°C.
