Today's Risk Map - "Extreme Instability"

Something to keep an eye on today... extreme instability along the international border should keep the risk of tornadoes about the Montana/North Dakota/Saskatchewan border intersection. The heavy rains are expected in south western Saskatchewan this morning and burn off with day time heating. Storms will fire up later this afternoon in Montana and remnants could drift into the southern most area of south east Saskatchewan. Risk of storms will be highest after 6pm for Estevan.

Moderate Risk for areas along the southern Manitoba/Saskatchewan border. Chance of a tornado, large hail, damaging winds and intense lightning.

Peak intensity of these storms will be between 3pm and 8pm.

Storms Ramping Up Today, Look Out For Tomorrow!

Widespread severe thunderstorms late this afternoon, strengthening into the evening and then running all night. Hot and humid air today will give rise to strong thunderstorms including supercells with golfball size hail and wind gusts up to 100km/hr. On Thursday morning, the remnants of today's storms will quickly emerge in south east Saskatchewan and move into southern Manitoba with near maximum force. This will be a dangerous situation. Areas from Yorkton to Winnipeg should prepare now for extremely severe weather tomorrow afternoon and into the evening.
