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!
