The final weekend of May will finish the month with cooler than normal conditions along with a chance of showers Saturday night into Sunday morning. High pressure building in for Saturday will give a sunny but cool start to the weekend, with patchy frost early Saturday morning outside the city. Afternoon highs are expected to reach 15 or 16C, but light winds and sunny skies will make those temperatures feel warmer. A system tracking through southern Manitoba Saturday night will bring a few showers across southern MB Saturday night into Sunday morning, with even a chance of some scattered thunderstorms. The unsettled weather should move off Sunday morning leaving partly sunny skies and afternoon temperatures near 20C. So all in all, it shouldn’t be too bad a weekend, but those waiting for summerlike weather will have to continue to wait. Model guidance is not suggesting any change to above normal conditions over southern MB through the next week or two. As for May, it looks like it will finish with a mean temperature around 8.3C at Winnipeg airport, some 4 degrees below normal, and the 15th coolest May since 1872.
