Two different scenarios featured by today's short and mid term forecast models. The hrrr shows more convection with storms over Regina, the NAM Nest is showing little to no convection for the city. Both models agree that the Estevan region will be in the DANGER ZONE from 4pm to at least 8pm. Regina might see more tornadic storms form later in the evening or overnight (7pm to 9pm and 1am). With experience of watching these patterns fold and unfold, our best guess is to put all of southern Saskatchewan on storm watch with southeastern areas ready to be on high alert in cast heat energy continues to over take the extreme humidity. Lack of ground water to the west will stir up winds, extreme humidity in the east may trigger tornadoes with this system.
A non-zero tornado risk has been added for both Alberta and southern Saskatchewan today. Extra rain showers overnight and this morning plus clearing out of smoke is increasing the possibility of strong thunderstorms, if anything they will be very discrete (small yet powerful) . More likely is the heat wave on Monday, with up to 35C/95F as a high temperature by 5pm. Perfect time to defrost the refrigerator!
