Winter Begins in Southern Manitoba

Brad Leave a comment

Cleanup continues across southern Manitoba as a wintery conditions settle into the region.

Winnipeg will see an unpleasant start to the day with the last bit of snow the region will see being blown about by northerly winds near 40 km/h. The low responsible for this wintery blast will start pushing off to the east today; as a result, snow across the region will come to an end this morning as winds ease to around 20 km/h. Skies will stay mostly cloudy with temperatures reaching a high of only around -2 °C.

Skies will cloud back over overnight as the next low to impact the region approaches. Temperatures will dip to a low near -10 °C with light winds.

Winnipeg will see cloudy skies on Saturday with temperatures rebounding to around -3 °C. More snow will move into the region with a weak low that will clip through the region into the Northern Plains. Snow will begin midday in the city and taper off to flurries in the evening. This system will produce close to 5 cm of snow near the U.S. border, but Winnipeg should only see around 2 cm. Systems like these can often track a bit further south than originally forecast, and if that comes to fruition then most of the snow will miss Winnipeg, lowering amounts down to 0–2 cm.

A clipper system will bring more snow to parts of southern Manitoba on Saturday.

A few flurries will be possible Saturday night with temperatures dipping to a low near -10 °C.

A broad ridge of high pressure over the region on Sunday should finally bring a little bit of sunshine back to the region. Winnipeg should see mixed skies with a cool high near -4 °C and light winds. Skies will cloud back over on Sunday night with temperatures dipping down to a low near -8 °C.

Long Range Outlook

A potent clipper system developing early next week will likely bring some more snow and rain to the region through the first half of next week.

Today’s seasonal daytime high in Winnipeg is 0 °C while the seasonal overnight low is -8 °C.

November Storm To Bring Snow, Wintery Mix to Southern Manitoba

Brad Leave a comment

The warm weather is on the way out thanks to a slow-moving storm system that will bring a mix of rain and snow to the province.

Winter is on the way for southern Manitoba. Precipitation will spread across the province through the morning hours, beginning as snow over much of western Manitoba and falling predominantly as rain over the Red River Valley. The precipitation will ease in the southwest corner of the province this evening, but will continue overnight through WestMan southeastwards through the Red River Valley and the southeastern corner of the province. Cooler air filtering in overnight will bring an end to all rain across the province as it switches over to snow.

The snow will continue across all of southern Manitoba on Thursday, including the southwest corner as snow returns to that area. Winds will intensify as a potent low pressure centre lifts towards Lake Superior while an area of high pressure builds into northern Manitoba. The Red River Valley will see northerly winds of 40–50 km/h combine with falling snow through the day, making for fairly miserable conditions across the region. Travel conditions will continue to deteriorate through the day.

Light snow will continue into Thursday night, finally tapering off closer to Friday morning. A few flurries will linger into Friday, but conditions should improve through the day.

This will be a major winter storm for many parts of the province. Here in Winnipeg, the city will likely see 5–10 mm of rain today, followed by 5–10 cm of snow tonight. By the time the snow tapers off on Friday morning, there could be quite a bit of snow on the ground. There’s some disagreement across models, and the near-freezing temperatures will complicate things, but it’s possible Winnipeg will see 15–25 cm of snow by Friday morning.

Winter will arrive in southern Manitoba this week with heavy snowfall across many areas.

Flurries will taper off on Friday, leaving behind cloudy skies and breezy conditions.

Other parts of the province will be hit even harder, with the potential for 40–50 cm of snow from portions of WestMan east-southeast across the Interlake and towards SE MB.

Temperatures in Winnipeg will hover around +3 °C today, then gradually cool towards the evening. Temperatures will drop to a low near -1 °C tonight, and then more or less hover there right through Thursday. Temperatures will dip to a low near -3 °C on Thursday night, and recover only a degree or two on Friday.

Long Range Outlook

After a brief break, another disturbance moving across the Prairies will bring some light snow to the region on Saturday afternoon. It will exit quickly, leaving cloudy skies for the rest of the weekend. Temperatures will hover just below seasonal values.

Today’s seasonal daytime high in Winnipeg is 0 °C while the seasonal overnight low is -8 °C.

Mid-Week Low Brings Warm Weather To An End

Brad Leave a comment

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.

RDPS Forecast 12hr. Precipitation Accumulation valid 00Z Thursday November 11, 2021
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.

Temperatures Set to Soar This Weekend

Brad Leave a comment

Winnipeg will see daytime highs climb over 10 °C above seasonal normals this weekend as a surge of Pacific warmth washes over the region.

Winnipeg will see very mild November weather over the next few days. While some of the mild air is in place already, today will be a semi-typical “transition day” for the Red River Valley. Temperatures will climb to around 10 °C in the city today with breezy southerly winds near 30 gusting 50 km/h. Cloud cover should increase today, beginning with partly cloudy skies this morning giving way to mixed to mostly cloudy skies this afternoon.

The southerly winds will ease and shift westerly this evening as a trough moves through the area. Skies should clear out behind it as temperatures dip to a low near +4 °C.

With a westerly flow in place for the weekend, even warmer daytime highs will move into the region. The region will see mainly sunny skies with light west-southwest winds. The high in Winnipeg will reach 13 or 14 °C, making for an absolutely beautiful early November day. Temperatures will fall to a low near +1 °C with partly cloudy skies on Saturday night.

RDPS 2m Temperature Forecast valid 21Z Saturday November 6, 2021
Very mild early November temperatures will spread across the southern Prairies this weekend.

More pleasant weather is on the way Sunday with highs back up into the low teens. Skies should be partly cloudy again with light winds. Lows will dip down again to around +1 °C.

Long Range Outlook

The beautiful weather will continue into the start of next week with highs near 10 °C on Monday and Tuesday. The overall pattern will begin to change mid-week as cooler air starts pushing southwards. Temperatures will slide back towards seasonal values with unsettled conditions through the second half of the week.

Today’s seasonal daytime high in Winnipeg is 2 °C while the seasonal overnight low is -6 °C.
