Things will seem decidely early-April as extremely cool air settles in over the eastern Prairies bringing another stretch of days with temperatures some 10-15°C below normal. Seasonal weather doesn’t look to return until the end of the week when the cold air finally begins being shunted off to the east.
We’ll see a mainly cloudy sky today as we remain stuck under cloud wrapping around the backside of the low pressure system that impacted Winnipeg and the Red River Valley over the weekend and the first half of the week. Accompanying the cloud cover will be extremely cool temperatures for mid-May; the daytime high today will only reach 6 or 7°C, 10-15°C below the seasonal high of 19°C. The cloud cover looks to begin clearing out ovenright as we drop down to a low of -4°C, again nearly 10°C below our seasonal low temperature for this time of year. No precipitation is expected today or tonight.
Tomorrow will bring a few clouds as we sit on the fringe of the organized cloud pushing off to our east and then see some afternoon cumulus clouds develop. Temperatures will moderate a little to around 10°C, however that’s still nearly 10°C below normal for this time of year. We’ll drop to a low of around -1°C overnight under clear skies.
Friday will bring plenty of sunshine with just a few clouds through the afternoon hours. We’ll see a high temperature of around 12°C as milder air continues to slowly push eastwards. There will be a few cloudy periods overnight as a weak disturbance moves thorugh and we’ll see an overnight low near 3°C. Precipitation is unlikely with this disturbance.
Returning to Near-Normal on the Weekend
Things will get back into form by the end of the weekend as the cold trough finally collapses and pushes well off to the east, allowing milder air to spill across the Prairies. Saturday looks like it will have a high somewhere in the mid-teens followed by temperatures near 20°C on Sunday. The weekend looks to be a bit of a mixed bag with sunny skies and relatively light winds on Saturday, but more cloud and stronger winds developing on Sunday as a warm front pushes into the region ahead of a low approaching from Wyoming. Areas all across Southern Manitoba may end up wtih the threat of some showers or rain activity by Sunday aftenroon. We’ll have more details on this system in Friday’s blog post.
