Those tired of the left-over gloom from the weekend’s weather will be happy to know plenty of sunshine is on the way as a building upper-level ridge brings seasonal temperatures and plenty of sunshine.
The weather for much of this week will be dominated by an upper ridge building across the southern Prairies, bringing pleasant conditions for the end of September with slightly above normal daytime highs. The next few days will bring plenty of sunshine with just a few clouds to partly cloudy skies expected.
Temperatures will gradually climb to around 5-6°C above seasonal by the end of the week; daytime highs near 17°C today in Winnipeg will increase to near 20°C for Thursday and Friday.
Fortunately, it doesn’t appear the wind will pose too much of an issue either. Winds will be calm today, and then increase to around 10-20 km/h out of the south for Thursday and 15-25 km/h out of the south on Friday.
Long Range
The weekend forecast gets a little more complicated, but overall it’s looking like the weather should stay dry until the start of next week.
As the weekend progresses, a long-wave upper trough will dig over the western half of the continent. We should remain relatively unaffected by this with mild weather continuing through the weekend. Late Sunday into Monday, a shortwave will eject northeastwards out of the trough, moving into Southern Manitoba, and will bring some rain to the region. The timing of this is uncertain at the moment, but it looks likely that it won’t move into the province until late Sunday at the earliest.
So until that moves in, the weather should remain quite nice with mild temperatures and relatively light winds.
Winnipeg’s seasonal daytime high is currently 15°C while the seasonal overnight low is 4°C.
