Snowy Transition Into the Deep Freeze

Brad

A disturbance tracking through Manitoba will bring accumulating snow tonight followed by much colder temperatures.

It will be a seasonably cool day in Winnipeg today with a high near -16°C as clouds spread into the region ahead of the approaching disturbance. Winds will pick up out of the southeast this afternoon to 30 gusting 50 km/h, producing uncomfortable wind chills in the -25 to -30 range. Snow will spread across the Red River Valley later this afternoon, but will stay light until the evening. Temperatures will continue to rise through the night as the wind gradually eases.

Skies will stay cloudy on Thursday as the snow tapers off through the day. Winnipeg will likely end up with a total of 10 to 15 cm of fresh snow from this system. Temperatures will climb a bit to a high near -11°C. The cloud cover will begin to break up on Thursday night with winds picking up out of the west to around 20 km/h. Temperatures will head to a low near -22°C.

Southern Manitoba will see a widespread accumulating snow Wednesday night into Thursday with some areas receiving as much as 10 to 15 cm.

The sun will return on Friday, but unfortunately it’s because of a large Arctic ridge moving into the province. As a result, Winnipeg will see seasonably cold temperatures with a high of only -18°C. Those westerly winds will continue for much of the day, gradually diminishing through the latter half of the afternoon. Skies will be partly cloudy over the region for much of the day, but will clear completely for Friday night. With calm winds, temperatures will head to a low near -30°C.

Long Range Outlook

The cold weather will be sticking around for a while. Highs will generally be well below seasonal averages through the next week, except for Sunday when a passing low brings near-seasonal temperatures for a day. The sun should be around for Saturday, but it looks like mixed to cloudy conditions will develop for the end of the weekend through the first half of next week.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -24°C.

Cooler With Mid-Week Snow

Brad Leave a comment

Temperatures will cool to seasonably cool values in Winnipeg after the passage of a low pressure system on Monday. An accumulating mid-week snowfall will then lead to even colder temperatures heading into the weekend.

Winnipeg will enjoy sunny conditions for much of today with temperatures climbing to a high near -2°C. Winds will pick up out of the south-southwest to around 30 km/h midday, then shift west-northwest by the evening to 40 gusting 60 km/h. This wind shift will bring more cloud into the region along with flurries that will persist for much of the night. A cold front passing through overnight will shift the winds solidly northwest and send temperatures to a low near -18°C Tuesday morning. The flurries will taper off sometime late overnight or early Tuesday.

RDPS Forecast 10m Winds valid 21Z Monday January 6, 2020
Moderate west-northwest winds will spread into the Red River Valley again on Monday.

Through the day on Tuesday, a sprawling Arctic high will build into the eastern Prairies. The northwest winds near 30 gusting 50 km/h will continue into the afternoon before gradually diminishing as the high arrives. Temperatures will be much cooler in Winnipeg than the values seen lately with a high near -16°C. Temperatures will dip to a low near -26°C on Tuesday night with light winds under mainly clear skies.

On Wednesday, a sunny start to the day will bring increasing cloudiness through the afternoon. A low pressure system moving into the U.S. will push an inverted trough across southern Manitoba on Wednesday night. As it approaches on Wednesday afternoon, winds will pick up out of the southeast to 30 to 40 km/h as temperatures climb to a high near -16°C. The windy conditions, combined with fairly cold temperatures, will result in some blowing snow through the Red River Valley, but the severity will be significantly limited by minimal snow cover in some areas. Snow will begin late in the afternoon and continue for most of the night.

NAM Forecast 1km Reflectivity with Precipitation Type valid 03Z Thursday January 9, 2020
A broad area of moderate snow will spread across southern Manitoba on Wednesday evening.

Accumulations over an 18 hour period or so will reach up to 10–15 cm in the Red River Valley and 10–20 cm to the west-northwest over southwest and western Manitoba. Blowing snow may produce poor visibilities overnight as the moderate snow combines with the windy conditions.

Long Range Outlook

Seasonal temperatures will stick around for Thursday with a continued chance of flurries and cloudy skies. Clearing will begin pushing into the region on Thursday night, marking the arrival of a colder air mass. Daytime highs will drop into the -15 to -20°C range on Friday and stay there right into next week. Overnight lows will drop as well, varying through the -20 to -30°C range.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -23°C.

Mild and Windy Weekend Ahead

Brad

Winnipeg will see cloudy skies and warm temperatures for one more weekend before cooler temperatures return.

Winnipeg will see cloudy skies with a chance of flurries as another disturbance moves through the region today. Temperatures will be mild with a high near -2°C with light winds. A weak ridge of high pressure will cross the province tonight, keeping skies on the cloudier side and winds light. The city will dip to a low near -9°C.

The major weather maker for the weekend will move into the Prairies on Saturday. A rather strong low pressure system will begin pushing into central Saskatchewan on Saturday, bringing with it a strong push of mild Pacific air. Winnipeg will see more cloud on Saturday with increasing south-southeast winds to 30 gusting 50 km/h. Temperatures will climb to a high near -5°C, then continue to climb overnight to around -2°C. The winds will ease for a short period on Saturday night, then pick up out of the northwest to 40 gusting 60 km/h early Sunday morning as the low passes.

GDPS 10m Wind Forecast valid 18Z Sunday January 5, 2020
Moderate west-northwest winds will develop over southern Manitoba on Sunday in the wake of a departing low pressure system.

Sunday will be a windy day with winds gradually easing to 30 gusting 50 km/h as temperatures stay steady near -3°C. There will be a chance for a few flurries as the clouds finally begin pushing off to the east. The departure of the low will usher in a significant pattern change for our weather, bringing an end to the persistent seasonably mild conditions that have been in place for a while now. Temperatures will dip to a low near -12°C on Sunday night and continue to cool into next week.

Long Range Outlook

Winnipeg will likely see a fair amount of sunshine through the first half of next week, but daytime highs will slip from around -10°C into the mid-minus teens. A weak low is forecast to pass through mid-week, which will then usher in another push of colder air, sending highs even cooler towards -20°C for the end of the week. No significant snowfall is forecast.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -23°C.

Mild and Cloudy Weather Ahead for Winnipeg With Chance of Snow

Brad

Winnipeg will kick off the new decade with mild temperatures, cloudy skies, and a couple more chances of light snow.

A low pressure system will move through the province today, bringing mild temperatures and plenty of cloud cover. Temperatures will climb to a high near -2°C in Winnipeg today with even warmer highs of 0°C near the U.S. border. Snow will spread southeastwards through the Interlake into southeastern Manitoba today. The band of snow will pass north and east of Winnipeg, but flurries are possible this afternoon and evening. Further south, a second area of light snow will track near the American border, but mostly fall south of the border.

Northwest winds up to 20 km/h will develop tonight behind the low, as temperatures fall to around -10°C. Skies will stay mostly cloudy.

RDPS 2m Temperature Forecast valid 21Z Wednesday January 1, 2020
2020 will start off with seasonably mild temperatures across all of southern Manitoba.

Thursday will bring pleasant weather to the region with a high near -7°C under mostly cloudy skies. The chance for flurries will continue through the morning into the afternoon. No notable features will over southern Manitoba, leaving the region with calm winds. Temperatures will dip to -11°C on Thursday night under mostly cloudy skies.

A more organized low will move from SE Saskatchewan into the Dakotas on Friday. As it does, a second low will move into central Manitoba from northern Saskatchewan. The southern low will support an area of snow that will extend some distance northwards along a trough connecting the two. How far north that snow is able to run up the trough is the unknown that will make the biggest difference on Friday. For now, there’s nothing more to say other than that there’s a chance of snow in Winnipeg, but the likelihood increases heading south towards the U.S. border.

Aside from the snow, it will be another seasonably warm day with a high near -6°C and light winds. Any snow that developed would likely be out of the region for the afternoon. Skies stay cloudy on Friday night with a low near -10°C.

Long Range Outlook

Another low pressure system will move through the province this weekend, likely bringing snow to many parts of the province. Behind this low, colder air will begin working its way into the region again. To start off next week, temperatures are forecast to return to seasonal values with variable cloudiness.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -23°C.
