Southern Manitoba

(south of 53°)

     

Discussion :

  
Significant heat will quickly return to the south today with daytime highs back into the upper 20's or low 30's expected across many areas. The heat will be in place for the next 2 to 3 days. This is due, in part, to an almost stationary high pressure area situated in southeastern Manitoba with ridging to the northeast and west. The air mass is stable so there is very little chance for any precipitation today or tomorrow. There is a strong zonal flow from west to east bringing a return of the smoky conditions for today and tonight.

Northern Manitoba will see scattered showers today and overnight as the cold front moves east. There will be a greater concentration of showers and possibly thunder showers in the vicinity of the cold front. Also, strong southwest to westerly winds with gusts up to 50 kph ahead of the cold front will be followed by strong north to northwesterly winds gusting up to 60 kph behind the cold front.
