One more day of spectacular warmth and sunny skies today before things change. Expect highs around 19 or 20°C today with just some high cloud. It will be becoming windier this afternoon with S/SE winds 40 gusting to 60 km/h possible. A few thunderstorms will be possible along the Saskatchewan Border today as well, especially this morning.
Tonight begins the turn around. A cold front will be slicing through southern Manitoba overnight and in the morning Saturday. A few showers will be possible along the front, and perhaps a rumble of thunder. Widespread and organised thunderstorms look unlikely thanks to limited instability and moisture. We should not see any significant accumulations. A couple mm possible in the heavier showers, but generally it's just a few sprinkles. Watch the comment section of this post for updates.
It will be much colder behind this system. Wrap-around precipitation may move in by Saturday afternoon and evening, but it doesn't look like we'll get significant accumulations with the worst staying to our north. It will be windy again tomorrow with westerly winds over 50 km/h expected by afternoon.
We will be spared the worst we can say. This system is expected to bring significant snow to parts of Saskatchewan tonight. Areas north of Regina and Yorkton could see in excess of 20 cm! That would be accompanied by strong winds creating whiteout conditions. Travel is not advised in Saskatchewan tonight and tomorrow for obvious reasons.
The cooler weather will continue for for most of next week before a warmup late in the week just in time for the weekend.
