Warmer-than-Seasonal Temperatures Continue

Although the second half of the week will see cooler temperatures than have been in place over the past 5 days, daytime highs will nonetheless still remain above the seasonal values near -2°C. Perhaps one of the biggest differences over the next few days will be that it will be significantly cloudier than seen over the past several days which will likely slow down the melting a little bit. Highs near or above 0°C will continue to keep the City of Winnipeg a slushy, sloppy mess, so don’t put away that spare bottle of windshield washer fluid yet!

A low pressure system developing in Alberta & forecast to track eastwards across the Prairies will bring continued warm weather alongside plenty of cloud.

Today will be a mostly cloudy day in Winnipeg with a chance for some non-accumulating light flurries as a weak warm front(fn) slides northeastwards through the region. After the passage of the front, there may be a rogue sunny break, but overall skies should remain mostly cloudy as temperatures climb to near +1°C with an easterly breeze. Cloud cover will thicken up tonight as the main support for the advancing low from Alberta begins pushing towards our region. Skies will be overcast tonight with temperatures remaining steady near 0°C.

Wednesday
+1°C / ⇒ 0°C
Mainly cloudy with a chance of morning flurries

Thursday
5°C / -1°C
Cloudy; chance of evening showers or flurries

Friday
3°C / -2°C
Mainly cloudy

Thursday will be an overcast day through the Red River Valley with light winds as a low pressure system tracks right across the region. Temperatures will be warmer – highs should be near 5°C – and no precipitation is expected through much of the day. Heading into the evening, a chance for some showers or flurries will spread into the Red River Valley alongside northwesterly winds to 20-30km/h behind the passage of a trough. The chance for some flurries will persist through the overnight period as temperatures drop to around -2°C.

Friday will be another mainly cloudy day. A few light flurries may linger into the morning hours, but in general most of the day will see no precipitation. Highs will climb to near +3°C with a chance for some sunny breaks in the afternoon. Skies will clear through the evening as we head to a low near -2 or -3°C.

Near-Seasonal In The Long-Range

This weekend looks to bring another surge of warmth to Southern Manitoba on Sunday that will push daytime highs into the upper single-digits, but looking further than that, near-seasonal temperatures are expected. This translates to daytime highs around the 0°C mark or so. The odd day here or there of slightly warmer-than-normal is possible, but all in all it appears that Winnipeg will be transitioning into a fairly dry, seasonal March pattern next week.

Fortunately, with daytime highs above 0°C many days and little snow expected, the erosion of the snowpack in the Red River Valley will continue over the coming week. With little snow expected, many regions in the valley could see snow-free conditions by the end of the weekend. This is particularly significant as areas of snow-free ground will warm up significantly more than snow-covered ground. As we head into the coming weeks and warmer and warmer air begins moving in, it won’t be uncommon to see 10°C temperature differences over short distances based solely on snow-cover.

After the bone-chilling February experienced in Winnipeg, there are no complaints to be had with how March has unfolded so far and looks to continue!

Warmth Arrives For The Weekend

The wait is over: the warmer weather has arrived. Today will mark the first day of a huge swell of warm air spreading eastwards across the Prairies over the next week that will bring seasonal to above-seasonal temperatures to the region. The warmer weather will be joined by a couple chances for flurries over the next few days as well thanks to multiple weak disturbances rippling along the edge of the warmer air.

Friday
-3°C / -10°C
Increasing cloudiness; a few evening flurries

Saturday
-2°C / -8°C
Mixed skies with a chance of evening flurries

Sunday
0°C / -4°C
Mixed skies

Today will start off sunny but see increasing cloud as temperatures will climb to around -3 or -2°C this afternoon. A weak low pressure system moving through the Interlake will bring the potential of flurry activity through the Red River Valley as it passes this evening, but any amounts from the system would be minimal. Temperatures will drop to around -10°C tonight.

Saturday will bring mixed skies with temperatures once again climbing towards the -2°C mark under mixed skies. Another low tracking through the region will bring another chance for some very light flurry activity through the late afternoon & evening hours. Expect an overnight low near -8°C.

Sunday will be the warmest day of the next few with temperatures climbing to the freezing mark. Skies will likely be mixed with somewhat breezy northwesterly winds to 20-30km/h. Sunday night will bring a balmy low of around -4°C.

Warm Weeks Ahead

Fortunately for us, the warm weather looks like it’s going to stick around for a while. The NAEFS 8-14 day outlook is showing a decent probability of above-normal temperatures while only a brief mid-week cool-down looks on the cards for next week.

With the relatively low amount of snow on the ground, we may be heading into positively spring-like weather!

Big Warm-Up on the Way

A significant large-scale shift in the upper-level weather patterns will result in a rather abrupt end to the cold snap that has plagued Manitoba through much of February and allow seasonal to above-seasonal temperatures to spread eastwards through the Prairies. Unlike the brief warm-ups that occurred through February that lasted perhaps a day or two, since this warming trend will be supported by a shift in the upper-level pattern, the warmer weather is looking like it will remain in place for at least 1-2 weeks.

Wednesday
-17°C / -26°C
Mainly sunny

Thursday
-9°C / ⇒ -10°C
Increasing cloud; chance of flurries

Friday
-2°C / -10°C
Mixed skies

Today will be the last straggling cold day of the bunch with daytime highs struggling into the minus teens. Unfortunately, a breezy northwesterly wind to 20-30km/h will be making things feel quite cool. A few clouds may be seen through the day, however an approaching Arctic ridge of high pressure should keep things fairly sunny. Temperatures will drop to around -26°C tonight with light southerly winds as the ridge slides by to our south.

Thursday will mark the transition towards significantly warmer weather. After a cold start to the day, southerly winds will gradually strengthen to nearly 40km/h as a warm front pushes into the province. We’ll see increasing cloud through the day which may result in some flurry activity at some point through the afternoon/evening. Temperatures will climb to around -9°C. Heading into the evening, winds will shift to the west and diminish; temperatures look like they’ll remain fairly steady around -10°C through the night with a slight chance of flurries continuing under mainly cloudy skies.

The warm weather will keep on pushing eastwards for Friday. Winnipeg should see high temperatures climbing to around the -2°C mark under mixed skies and fairly light winds. Temperatures will drop to around -10°C on Friday night.

Warm Weather Keeps on Coming

For winter-weary Winnipeggers, it’s nothing but good news in the long-range. Warmer weather – either near-seasonal to above-seasonal – is expected to persist for quite a while for the region. A broad upper-level ridge is forecast to shift from being centred over the west coast further eastwards into the Prairies.

The result will be a flow of milder Pacific air spreading eastwards through the Prairies, resulting in daytime highs near the freezing mark. Given the lower-than-normal snowpack, we may potentially see a fair amount of snow melt thanks to the stronger sun & milder temperatures over the coming weeks.

Cooling Down Again

We’ll have a warm, but windy, Monday before another arctic cold front comes through, returning below-normal temperatures to the region.

Monday will be warm and windy as strong southerlies develop

Monday
-6°C / -18°C
Mainly sunny

Today will be warm, but windy as a strong southerly flow develops ahead of a cold front. Wind speeds will be 40km/h gusting to 60km/h, making it feel significantly colder than it will actually be. High temperatures in the mid to upper minus single digits will end up feeling more like -15 to -20 when you factor in the wind.

Tuesday
-16°C / -24°C
Mainly cloudy with flurries

An arctic cold front will move through early on Tuesday, ushering in colder weather once again. As the cold front goes through we’ll also see some flurries, but accumulations will be small. Wind speeds will really pick up in association with this front, with north-west winds of 40km/h gusting to 60km/h for much of the day. This will send wind chill values close to -30.

Wednesday
-21°C / -28°C
Mix of sun and cloud with chance of flurries

Wednesday will be even colder than Tuesday as arctic air becomes entrenched in southern Manitoba. High temperatures will be near -20, with the wind chill making it feel more like the -30s. We may also see some light flurries throughout the day as the low-levels of the atmosphere become unstable.

Long Range

Long range models suggest we’ll begin to see more frequent warm weather by next weekend. This will be the result of a western ridge extending further east into Manitoba. That doesn’t mean all the snow is suddenly going to disappear, but it will certainly be more pleasant. March 1 was the beginning of meteorological spring, so it’s just a matter of time before spring actually arrives!
