Saskatoon Forecast
Today
It was an extremely mild start to the day with temperatures only dropping back to 14 degrees this morning.
Mostly sunny skies and a breezy south-southeasterly wind kicked once daybreak hit, helping to warm us up into the mid 20s by late morning.
This is expected to be Saskatoon’s second hottest day so far this year with an afternoon high in the low 30s, feeling like 33 or 34 with humidity, as clouds roll back in with a chance of showers and thunderstorms later today.
Tonight
Clouds will linger overnight as the upper ridge that brought in the heat breaks down, but the cloud cover will keep us fairly mild with a low in the mid teens.
Friday
An upper trough and low pressure system sweep through the province tomorrow destabilizing our atmosphere, keeping us mostly cloudy and bringing in a chance of afternoon showers and thunderstorms.
Winds will also transition to the west during the day, picking up to 30 km/h with gusts upwards of 50 km/h as we warm up to around 27 degrees before cooling back into the mid 20s later on.
Weekend
We’ll get into a cooler northwesterly flow Saturday with wind gusts upwards of 60 km/h possible under a mix of sun and cloud with a daytime high in the mid 20s.
Sunday winds will ease a bit as we get into some more sunshine with an upper ridge poking back in and helping to warm us back up into the high 20s for a daytime high.
Work Week Outlook
That ridge will be short-lived, starting to break down by mid-week with mostly cloudy skies and a chance of showers moving in, dropping daytime highs from 27 degrees Monday, back into the mid 20s.
