The summer heat that’s been in place over the region this week will come to an end as a cold front sweeps southwards.
Before the cooler weather arrives, though, southern Manitoba will have one more hot day. Another low pressure system moving towards the province will push more warm air into the southern portion of the province today. Daytime highs will again climb up to around 30 °C with plenty of sunshine this afternoon.
Conditions will finally change tonight when a cold front sweeps southwards. It will bring a chance of showers or thunderstorms to the region overnight into Saturday morning as it moves through. Temperatures will dip into the upper teens as light northerly winds develop.
The chance of rain will taper off on Saturday morning as north winds pick up into the 20–30 km/h range. Temperatures will climb up into the low- to mid-20s in the afternoon under partly cloudy skies. Heading into the night, temperatures will drop into the mid-teens with light north winds.
Sunday will bring a repeat of Saturday as a broad area of high pressure builds into the province. Temperatures will again climb into the low- to mid-20s under partly cloudy skies. Winds will be light out of the north through the day. Clouds may move in on Sunday evening as temperatures dip down into the low teens.
The other notable change for the weekend is that while lingering humidity may stick around through Saturday, much drier air will push into the region by Sunday, offering relief from the more humid weather of the past week.
Long Range Outlook
Next week will bring seasonably cool temperatures with daytime highs in the 20–25 °C range and overnight lows in the 10–15 °C. A partly cloudy start to the week could turn unsettled mid-week, but settled conditions should develop for the end of the week.
Today’s seasonal daytime high in Winnipeg is 26 °C while the seasonal overnight low is 13 °C.
