Early Taste of Spring Continues, Winter Storm Looms on Horizon

Brad Leave a comment

Winnipeg will see March will kick off the same way February ends: with high temperatures near 0°C bringing an early taste of spring to the region.

The mild weather Winnipeg has seen over the past couple days isn’t going anywhere. A mild Pacific flow will continue through the rest of the work week, bringing near-freezing highs to the region. Tonight and Thursday night will both see overnight lows near -10°C.

Winnipeg will see plenty of sun as well. A few clouds will move through the Red River Valley today, but then mainly sunny skies will be in place through Thursday and much of Friday. Some cloud will begin moving into the region late Friday ahead of a low pressure complex organizing in the United States. The cloud cover will keep Friday night’s low warmer, only dipping down to around -3°C.

Long Range Outlook – Winter Storm Brewing

The weather will turn more unsettled for the weekend as a series of low pressure systems move through the region. Mild temperatures will continue in Winnipeg, but cloudy skies will persist through the weekend into the first half of next week.

There will be a couple of chances for snow – or even a rain shower – through the weekend. Come Sunday night through Monday, what may end up as the biggest storm thus far in the 2017/18 winter season moves through. While it’s too early to put much trust in any of the forecasts, some guidance suggests Winnipeg and the Red River Valley may see over 25 cm of snow with this storm system.

A complex, slow-moving low pressure system may bring Winnipeg the biggest winter storm of the 2017/18 season on Sunday night into Monday.

For now, just keep it in mind that there is the chance for a major snow storm to start next week. If you have travel plans involving driving on Monday, consider contingency plans just in case.

Until then, enjoy the beautiful sunshine and mild temperatures!

Winnipeg’s seasonal daytime high is currently -5°C while the seasonal overnight low is -15°C.

Windy Saturday Brings Seasonal Temperatures Back

Brad Leave a comment

Winnipeg will see a mixed bag of conditions over the coming days as seasonal temperatures build back into southern Manitoba.

Winnipeg will finally move towards seasonal temperatures as the icy grip of Arctic air is shown the door by milder Pacific air spreading eastwards across the Prairies. To round out the work week, Winnipeg will see mainly sunny skies once a bit of morning cloud moves out of the region. Temperatures will climb to around -8°C, just a tad warmer than it was yesterday. Skies should remain mainly clear tonight with temperatures dipping down to around -17°C.

Warmer air will push into the region for Saturday, but it will come with those wonderful southerly winds that Winnipeg so often receives when warmer weather is on the way. Temperatures will climb to a high near -5°C, but those southerly winds will strengthen to 30 to 40 km/h with gusts up to 60 km/h by Saturday afternoon. Skies will start off sunny, but by mid- to late-afternoon, cloud will begin moving into the region from the south. The wind will taper off through the evening as skies continue to cloud over. Some light snow will move into southern Manitoba overnight, but nothing more than a skiff is expected. Besides bringing the snow, the cloudy skies will help temperatures remain a bit milder with a low near -11°C expected in Winnipeg.

Winnipeg will see some light snow move through the area on Saturday night into Sunday morning.

Winnipeg will see cloudy skies on Sunday with any remaining light snow tapering off in the morning. Winds will be much lighter, and temperatures will climb to a high near -4°C. Winnipeg may see some clear breaks on Sunday night, but more cloud will begin pushing in early Monday morning as another low pressure system moves into the region.

Long Range Outlook

Milder temperatures look like they’re here to stay, with seasonal to slightly above seasonal temperatures remaining in place for much of next week. Precipitation still looks minimal, though, with no significant snow expected in the coming week.

Winnipeg’s seasonal daytime high is currently -6°C while the seasonal overnight low is -16°C.

Arctic Chill On Monday Gives Way to Warming Trend

Brad Leave a comment

After a cool Monday, Winnipeg will undergo a slow and steady climb back towards seasonal temperatures under variable cloudiness.

Today will be the coolest day of the upcoming week in Winnipeg as an Arctic ridge moves through the region, bringing high temperatures -17°C. Winds will remain light through the day, but Winnipeg will see clouds work in through the afternoon from the south as a storm moving through the Northern Plains spreads clouds well northwards of its path. Temperatures should dip to a cool low near -22°C tonight with a fair amount of cloud remaining over the city.

Cloudy skies will remain over the city on Tuesday as a weak warm front pushes into the region from the northwest. Temperatures will be quite a bit milder than Monday with highs forecast to climb to around -12°C with light northerly winds continuing. We may see a bit of non-accumulating light snow through the day as temperatures hover right in a favourable zone for spontaneous snowflake creation, but nothing particularly notable is expected. Temperatures will dip to a low near -21°C on Tuesday night under clearing skies and a light west-southwest wind.

Wednesday looks to bring the sun back to Winnipeg with just a few clouds around as another low pressure system tracks through central Manitoba. Temperatures will continue trending warmer with a high near -10°C and winds will continue out of the southwest at 10 to 20 km/h. Skies should remain mainly clear on Wednesday night with a low near -17°C

Long Range Outlook

It’s finally looking as if the persistent polar vortex near Southampton Island in Hudson Bay that has resulted in steady north-northwesterly flow over much of the Prairies – and associated cold air outbreaks – is finally going to be shifting off to the east and weakening this week.

This will allow temperatures to moderate from the well below-seasonal values Winnipeg has seen for so much of February; by the end of the week, high temperatures may climb slightly above-seasonal! The warm weather won’t be coming with much of a risk for precipitation either, so all in all, it looks like a gradual moderating trend towards seasonal to slightly above-seasonal temperatures!

Winnipeg’s seasonal daytime high is currently -7°C while the seasonal overnight low is -17°C.

A Breezy Break from the Arctic Chill

Brad Leave a comment

Winnipeg will see variable cloudiness over the next several days with breezy conditions while the city is given a brief reprieve from unseasonably cold temperatures.

Today will be a considerably more pleasant day in Winnipeg than yesterday was, with a much warmer high near -8°C this afternoon as a weak low moving into the Interlake ushers a seasonal air mass into the region. Winds will be a bit breezy out of the south this afternoon, strengthening to around 20 to 30 km/h and producing wind chill values in the -15 to -20 range. This will still be much more pleasant than the -35 wind chills Winnipeg saw for much of Thursday. Winnipeg should see plenty of sun through the first half of the day, but clouds will begin moving into the region in the afternoon as the low approaches, with skies becoming cloudy by mid-afternoon. Expect cloudy skies on Friday night with just a slight chance of some non-accumulating light snow. Winnipeg should see a low near -15°C.

Saturday will see skies clear out early in the morning with temperatures recovering to a high near -10°C. Winds will be breezy out of the west at around 30 gusting to 50 km/h, creating wind chill values near -20. The Arctic front will slump back southwards on Saturday evening, bringing more cloud to the region as temperatures drop to a low near -21°C. There will be just a slight chance of some non-accumulating light snow on Saturday night.

Winnipeg will find itself north of the Arctic front once again on Sunday morning.

With Winnipeg behind the Arctic front once again on Sunday, temperatures will be well below seasonal with a high near -17°C. Any cloud left in the region should clear out midday, and winds will be out of the north at around 10 to 15 km/h, creating wind chill values near -25. With clear skies much of Sunday night, temperatures will drop to a well below-seasonal low near -25°C.

Long Range Outlook

In what is becoming a notable trend, Winnipeg’s long-range forecast continues to lack any significant precipitation, with nothing more than a trace of precipitation forecast in the next 7-10 days. Passing systems will bring some cloud to the region, but generally speaking, things will remain dry. Below-normal temperatures will likely persist into the middle of next week, but then a trend towards more seasonal temperatures is expected.

Winnipeg’s seasonal daytime high is currently -8°C while the seasonal overnight low is -18°C.
