The fine summerlike weather of September will give way to a temporary cooldown beginning Thursday afternoon as a cold front pushes through Southern Manitoba from the north. Thursday morning will start off much the same as September has been all month so far.. sunny and warm. Southwest winds of 20 to 30 km/h will allow temperatures to warm to 24 or 25 degrees by the noon hour before winds shift into the north by early afternoon. These northerly winds will tap much cooler air over central Manitoba, and our temperatures will likely be dropping though the afternoon to around 18c by evening. Temperatures will continue to drop Thursday night with a forecast low of +4C by Friday morning. Sunny skies and cool temperatures are forecast for Friday with highs only around 17C.
The good news is that the weather should be dry and mild through the weekend as a large ridge of high pressure dominates the weather picture. Temperatures will remain near normal with highs around 20C but with light winds and sunshine.. conditions will be ideal for outdoor activities. Temperatures are expected to rise above normal again next week as the ridge of high pressure moves east and southerly winds bring warmer air into southern Manitoba once again.
