Thunderstorm Outlook with Risk of Tornadoes in Alberta

 It was very foggy this morning in Regina, models show that as it clears up the thunderstorms also clear right out. Absolutely zero rain or anything close to a thunderstorm on both hrrr and NAM Nest forecast models across the eastern prairies this evening. Tuesday looks like our day. Tornadic storms from Alberta this afternoon and evening should arrive in southern Saskatchewan by Tuesday afternoon/evening according to the NAM Nest.

Sunday, August 17th, 2025 Moderate Risk for Saskatoon Regina and Yorkton #skstorm

Here is today's thunderstorm outlook plus current radar with lightning overlay which shows how active the weather is already as of 9am this morning. Forecast models suggest a strong storm popping up either at 3 to 4pm or 6 to 7pm depending on the model. Both showing the storm starting off in the Regina city area, one more spread out and dumping more rain than the other. Timing will be key today. There might be a very short window to film a storm today at Wascana Lake, should be a fun day!

 

Sunday Models: Potential Storms for Regina

 

The 12z runs of both NAM Nest and hrrr show thunderstorm activity in the city of Regina area Sunday evening, August 17th, 2025. Rainfall totals show a couple storms, one for the north side and the second will cover the city mostly on the south side later at night. Keep in minds these models change a lot from run to run. Radar and sky watching is the best way to know if there is a storm. The computer is just tossing out guesses. Not an official forecast, its Play by Play of Local and International Weather Events! 

Saturday Multi Sector Supercells

Here is today's thunderstorm outlook from PASPC showing multiple sectors in the yellow moderate risk zone. Tornado risk for Edmonton and areas to the east of the city today. Southern Saskatchewan is primed for a strong supercell along the southern border. Sunday looks much better for the city of Regina for multiple waves of storms. Generally today will be the western prairies.
