Mild Weather Challenges Record, Then Slumping Towards Seasonal

Brad Leave a comment

Temperatures will climb well above freezing today and challenge a daytime high record over 100 years old. The significant warmth will ease through the remainder of the weekend, but temperatures are still expected to remain above-normal into the beginning of next week.

Winnipeg will see a cloudy and mild start today with temperatures starting out near 0 or +1°C. Temperatures will climb through the day, reaching a high near +5°C as the sun starts breaking out from behind the clouds later this afternoon. This high will challenge the current daily record high for January 19th of 5.6°C, set first in 1900 and then tied again in 1908. Winds will be out of the southwest at 20 to 30 km/h, gusting at times to 40-50 km/h. Skies will remain partly cloudy for the evening, then cloud back up overnight as a cold front slowly slumps southwards out of the Interlake. Winnipeg will see a low near -8°C.

A mild air mass will bring daytime highs near 5°C to the Red River Valley today

Saturday will bring mixed skies to the city – looking cloudier in the morning and a but sunnier in the afternoon – with a high near -2°C. It’s quite a bit cooler than Friday, but still well above the seasonal high of -13°C. There isn’t too much else to say! Saturday night will see mainly cloudy skies and a low near -8°C. Sunday will bring mixed to cloudy skies with a high near -5°C and a low near -10°C. Winds will remain light.

Long Range Outlook

The first half of next week will bring variable cloudiness to Winnipeg with temperatures continuing to trend towards seasonal values. No significant snow is on the horizon. All things considered, it’ll be beautiful January weather!

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

Cold Conditions Continue through the Weekend

A slight warm-up on Sunday won’t make much of a difference: cold weather continues into the first half of next week.

Winnipeg will be locked under the influence of a sprawling Arctic high that will keep daytime highs around -20°C both today and tomorrow under sunny skies. Temperatures will once again dip back down towards -30°C tonight, but some cloud pushing into the area late Saturday ahead of some warmer air pushing in will temper the cold a bit and keep overnight lows to around -25°C. Winds will be light at 10 to 20 km/h today, tonight and tomorrow. Winds will pick up out of the south on Saturday night to around 20 to 30 km/h as skies cloud over.

A few flurries will move thorugh portions of southern Manitoba on Sunday morning.

A passing low pressure system will bring some light flurries to the Red River Valley on Sunday morning as slightly warmer air pushes into the region. Temperatures should climb to a relatively balmy – but still below seasonal – minus 16°C or so with winds shifting to the northwest midday and picking up to around 30 km/h. Skies will clear out overnight as temperatures head to a low near -28°C.

Long Range Outlook

Early next week will see bitter cold return to the region as another Arctic high arrives. Highs will fall into the mid-minus twenties on Monday with overnight lows again near -30°C. A big change is on the horizon, though, as the large-scale weather pattern begins a pretty significant shift and an upper-level ridge starts building into the Prairies. By mid-week, daytime highs are expected to climb towards -5°C, with the potential of near-0°C highs by the end of the week!

This shift to milder weather will come with variable cloudiness with little chance of snow.

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

Below-Seasonal Temperatures Return to Winnipeg

Tuesday offered brief relief from the cold, but with the passage of a cold front late in the day, cooler air has returned to the region sending daytime highs back into the -20s.

Over the next couple days, the weather for Winnipeg and the Red River Valley will be a result of an Arctic high slumping southwards through the province. This will produce partly cloudy skies both Wednesday and Thursday, with daytime highs in the -21 to -19°C range. Tonight will be the coldest night in the remainder of the week with lows dipping down to around -28 or -29°C, while Thursday night will bring a slightly warmer overnight low in the mid-minus 20s.

Much of Manitoba will be under the influence of an Arctic high on Wednesday and Thursday

Friday will bring mainly sunny skies, but winds will pick up out of the south-southeast later in the day to 20-30 km/h as the high centre moves towards Lake Superior and milder air starts to work in from the west. Winnipeg should see a high near -19°C, with cloud cover beginning to increase in the evening hours. Temperatures will climb overnight as the clouds thicken up and milder air begins working into the region, reaching around -16°C by Saturday morning. Some light snow will be possible over southwestern Manitoba, but at this point it seems unlikely that it would manage to push eastwards into the Red River Valley.

Long Range Outlook

This weekend has the potential to bring seasonal to slightly above-seasonal temperatures with daytime highs climbing into the -11 to -8°C range and overnight lows in the mid-minus teens. This is thanks to a low pressure system that will move through northern Manitoba; while there may be a chance for some light snow as it moves through, the accumulating snowfall will likely remain through northern and central Manitoba.

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

Winnipeg Set For A Mild Weekend, But A Big Cool Down Looms on Horizon

Brad Leave a comment

The mild weather Winnipeg has seen lately will last for a few more days, but a low pressure system that tracks across the northern United States on Sunday night will usher in a major pattern change which will allow Arctic air to spill southwards across the Prairies, bringing significantly colder temperatures to southern Manitoba.

Warm, unremarkable weather is on tap for Winnipeg today and tomorrow as a slack flow remains over the region with just a few very weak upper-level disturbances moving through. A weak upper-level disturbance moving into the region will bring increasing cloudiness today as temperatures head to a high near +1°C. No precipitation is expected and winds will remain light. Temperatures will dip down to a low near -7°C tonight with the clouds clearing out by Saturday morning.

Winnipeg will see partly cloudy skies on Saturday with temperatures rebounding to a high near 0°C with light southerly winds. Temperatures will then dip to a low near -6°C on Saturday night with increasing cloudiness.

Everything begins to change on Sunday as a low pressure system develops across the northern Plains of the United States. There’s still a fair amount of uncertainty associated with this low; some models want to keep it relatively progressive and move it through South Dakota, while others develop a more potent Colorado Low that lifts northeastwards towards Thunder Bay. Either way, it should bring mainly cloudy skies to the region on Sunday with a chance for snow moving in on Sunday night. Given the significant uncertainty with this system, an update on what to expect will be posted sometime Saturday evening or Sunday morning.

Long Range Outlook

Without question, the biggest aspect of the long-range forecast is the dramatic cool-down that will occur next week.

By Tuesday morning a much cooler air mass is forecast to be in place over the province

As Sunday’s low pushes eastwards, a large upper-level ridge will build over British Columbia, remaining anchored over the Rockies. A large upper-level trough will develop over eastern North America, bolstered by the incoming low pressure system from the Northern Plains.

This pattern will result in a steady northwesterly flow over the Prairies, setting up an Arctic pipeline that will usher much colder air southwards into the Prairies. It appears that by mid-week, daytime highs in Winnipeg may fall into the mid-minus teens. Another way: by the middle of next week, Winnipeg’s daytime highs may fall to what the seasonal overnight lows are for this time of year.

So, enjoy the mild weather while it lasts, by this time next week it will be a whole lot colder than it is now!

Winnipeg’s seasonal daytime high is currently -7°C while the seasonal overnight low is -16°C.
