Today will be the mildest day of the holiday weekend as gusty southerly winds push temperatures up to 18-20C over southern MB with morning sunshine giving way to high cloudiness during the day. A southerly breeze will keep temperatures mild tonight, with lows of 10-12C . Early Monday however, a sharp cold front will sweep across southern MB from the north, bringing strong northerly winds and falling temperatures. In Winnipeg, the front is expected to pass through between 5 and 8 am, dropping temperatures from sunrise values near 12C to about 5C during the morning, remaining steady or recovering only slightly in the afternoon. This will lead to a widespread frost Tuesday morning across southern MB with morning lows of –2 to -5C likely under clear skies and light winds.
Cooler than normal weather is expected for much of the upcoming week with showers possible Wednesday. The good news is that long range guidance is finally indicating a nice prolonged warmup by next weekend with temperatures in the 20s, hopefully taking us through the end of May.
