Thunderstorms bring heavy rains just south of Winnipeg
A band of thunderstorms developed south of the city Friday evening and remained nearly stationary in an east to west band generally staying along and south of the Perimeter highway. While the city saw little or no rain, Oak Bluff reported at least 25 mm of rain while Sanford had 30-40 mm between 6 and 9 pm. The rain dropped off sharply north of Wilkes Ave with just a trace amount in Charleswood. That's what you call "local" downpours! Notice the distinct "outflow" boundary on the radar image (thin blue arched lines) produced by cool air flowing out of the thunderstorm activity to the south. Radar image is from 7:50 pm Friday evening.
