Stettler, Alberta is in for a stretch of warm and mostly sunny weather through Saturday, perfect for outdoor plans, before a shift to cloudier and wetter conditions arrives for the weekend. Environment Canada calls for daytime highs climbing to 25°C on Friday under sunny skies.
As of Wednesday afternoon, the temperature at the Stettler weather station sat at 21.4°C with moderate west-northwest winds at 17 km/h and comfortable humidity. The forecast shows a high of 24°C on Wednesday, cooling slightly to 21°C Thursday under a mix of sun and cloud, then warming to 24°C on Saturday. Overnight lows will range from 7°C to 11°C, near the seasonal norm of 10°C.
A pattern change is expected Saturday night as an active storm track slides across the Rockies into central Alberta. Saturday night’s forecast includes a 60 per cent chance of showers, and the unsettled weather looks to stick around through Monday. Sunday has a 40 per cent chance of showers and Monday a 60 per cent chance, with highs of just 19°C both days. No weather alerts are in effect at this time.
The weekend cooldown is part of a broader August pattern that The Weather Network says will bring above-normal temperatures to much of the Prairies but also periods of stormy weather spilling east from British Columbia. For Stettler, the best days for outdoor activities remain Wednesday through Saturday, before the rain chance ramps up Sunday and Monday.
