Mild Weather Continues

Warm temperatures will continue in Winnipeg as a slow-moving upper ridge continues its trek eastwards across the Prairies.

An upper ridge over the Prairies is bringing mild conditions to Winnipeg with plenty of sunshine. WIth the storm track deflected well to the north, the city will see dry conditions over the coming days. It will be easy to enjoy the late-fall warmth!

Winds will stay relatively light today out of the west up into the 20–30 km/h range. On Thursday, though, a low crossing the northern Prairies will strengthen winds in the Red River Valley out of the south into the 30–40 km/h range. On Friday, the city will likely see light winds to start the day then pick up out of the northeast as a large low complex begins to develop in the United States.

Much of southern Manitoba will see mild temperatures with daytime highs in the upper teens on Tuesday.

Overnight lows will also be mild over the coming nights with values in the low to mid-single digits.

Long Range Outlook

As we mentioned on Monday, a potent Colorado Low is forecast to develop this weekend and move into the southern Prairies. Forecast models are beginning to gather some consensus on the track of the system, trending towards a track that takes the low across southeast Saskatchewan on Sunday, western Manitoba on Sunday night, and northeastwards towards Hudson Bay on Monday.

This system will likely produce a swath of 20 to 50 cm of snow on its western and northern flanks, which would put it across southern Saskatchewan northeastwards into west-central Manitoba and onwards to Hudson Bay. This heavy snow combined with winds gusting up to 80 km/h would likely produce widespread blizzard conditions across the affected areas.

All major forecast models have a potent winter storm moving into the Prairies on Sunday.

To the south and east of this low track, some light snow or rain is possible, as well as the potential for a broad area of low cloud and drizzle. Temperatures could stay rather warm in the southeastern quadrant of the storm with highs potentially climbing into the low teens.

Regardless of the storm track, this system will usher in much cooler weather for next week with daytime highs dropping below freezing for the rest of the week.

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

Beautiful November Weather Ahead

The forecast is short and sweet to start the week: sunny and warm!

A broad upper ridge building across the Prairies has finally arrived in southern Manitoba. As a result, it will bring plenty of sunshine as temperatures climb into the low teens right through the next few days.

The southern Prairies will enjoy a late-year warm spell with temperatures in the teens across much of the region.

Winds will also be light through the coming days, generally no more than 15–25 km/h.

There really isn’t much to say! Enjoy this nice stretch of mild November weather!

Long Range Outlook

Conditions will turn cloudier towards the end of the week as the upper ridge begins to collapse and a couple lows track across the central Prairies. Temperatures will stay warm until Thursday, then begin cooling towards seasonal values.

Weather models are all showing a fairly potent winter storm developing this weekend in the form of a Colorado Low. There is still a large discrepancy on the track of the low, but there is good agreement that this storm could bring 20 to 30 cm of snow along a swath somewhere through the southeastern Prairies.

While there’s little agreement in where the snow will fall right now, but regardless of that, this system will usher in much cooler conditions for next week. Daytime highs will fall back below seasonal values through the first half of the week.

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

Mild Weather Continues

Winnipeg will continue to see seasonably mild and windy weather this weekend.

Temperatures will climb into the mid-teens quickly this morning, but a cold front passing midday will cap the high near 16 °C. Behind the front, breezy northwest winds up to 40 gusting 60 km/h will develop for the afternoon hours. Although the front will bring some clouds to the region, there will be plenty of sun through most of the day.

The winds will taper off this evening as a ridge of high pressure builds in from the north. Winnipeg should see a low near +1 °C with partly cloudy skies.

Temperatures will be a bit cooler on Saturday as the ridge leaves the region. Winnipeg will see mostly sunny skies with a near-seasonal high around 13 °C. Winds will pick up out of the south in the afternoon to 30 gusting 50 km/h and then increase to 40 gusting 60 km/h overnight. These southerly winds will bring a surge of warm air northwards and the city will see a mild overnight low 10 °C.

The Red River Valley will see mild temperatures with daytime highs climbing into the low 20s on Sunday.

A low pressure system passing through on Sunday will bring mostly cloudy skies to the region for the day. Winds will continue out of the south at 30 to 40 km/h, continuing to tap into warmer air. This will send high temperatures to around 20 °C. There will be a little bit of instability in the region through the afternoon hours that may result in a few showers or thunderstorms. The chance is low in the Red River Valley and much more likely that the southeastern corner of the province.

Winds will shift to the southwest and ease to 20 km/h on Sunday night with mixed skies. Temperatures will still stay seasonably mild with a low near 8 °C.

Long Range Outlook

Temperatures will shift back towards seasonal values through the first half of next week. Many forecasts show cooler weather moving in for the second half of the week with daytime highs dipping into the 5–10 °C range. Dry weather is forecast to continue through much of the week.

Today’s seasonal daytime high in Winnipeg is 12 °C while the seasonal overnight low is 1 °C.

Summer Scorcher Leads to Unsettled Weather

The summer heat will gradually wane over the coming days as unsettled conditions move into the region.

A large upper ridge over the Prairies will bring another day of scorching weather to southern Manitoba. With blazing sunshine, Winnipeg will see temperatures soar to a high near 34 °C. Dew point temperatures will stay in the mid- to upper teens, producing humidex values near 40 through the afternoon.

Tonight, a low pressure system will slide across the province, dragging a cold front with it to the east. That will bring some cloudiness to the city overnight as temperatures dip to a low near 16 °C. Heading through the second half of the night, Winnipeg will see a low chance of showers or thunderstorms as the low moves into the Red River Valley.

Scorching hot summer temperatures will be in place across the southern Prairies today.

On Thursday, any chance of rain will come to an end in the morning as the low moves off to the east. Temperatures will quickly rise to a high near 32 °C with partly cloudy skies for the rest of the day. The winds will shift to the north for the afternoon behind a weak cold front that moves through the area. Temperatures will dip to a low near 16 °C on Thursday night with a few clouds.

On Friday, a shortwave moving eastwards will run along a warm front draped across southern Manitoba. Skies will be mixed to cloudy with a good chance of some showers or thunderstorms through the day. Winnipeg should see a high near 26 °C, but it will be sensitive to the exact placement of the warm front and how much sun manages to poke out. If it ends up a tad on the sunnier side, temperatures could climb as high as 30 °C. Some marginally severe thunderstorms may be possible and there is the potential for some training storms resulting in locally high rainfall accumulations in bands parallel to the warm front.

The unsettled conditions will clear out on Friday evening with temperatures dipping to a low near 17 °C.

Long Range Outlook

The weekend will bring more settled conditions back to the region with seasonably warm highs in the upper 20s. On Sunday, a weak disturbance passing through may bring the chance for thundershowers back to the region.

Today’s seasonal daytime high in Winnipeg is 24°C while the seasonal overnight low is 11°C.
