Widespread freeze tonight.. warmer weather for end of week into next week
The first blast of fall like weather pushed into southern Manitoba yesterday, resulting in below normal temperatures, gusty north winds, lake effect precipitation and frost over parts of southern Manitoba this morning. Well below normal temperatures continued today with brisk northwest winds keeping temperatures only near 10C this afternoon. For tonight, a ridge of high pressure over Saskatchewan will build over southern Manitoba bringing clearing skies and light winds. This will lead to a widespread freeze over southern Manitoba by Thursday morning, with overnight lows of -1 to -4C forecast in most areas. (Downtown Winnipeg and areas along the MB lakeshores should escape the freeze tonight) The first frost over Winnipeg and the Red River valley usually isn't until the third week of September, so this year's first frost is arriving about a week earlier than normal. Sunny and milder weather will develop Thursday into Friday as the high pressure ridge pushes east and we get into a moderating southerly flow. A frontal system pushing in from the west threatens showers for Sunday.
