A line of thunderstorms ahead of a warm front produced heavy rain across the northern Red River valley Friday morning. The storms rolled into Winnipeg about 5 am and continued through much of the morning, dumping 25 to 40 mm of rain across the city by 10 am. A lightning strike even knocked off part of a church tower downtown around 6:45 am. The line of thunderstorms settled just south of the city between 8 and 10 am, dumping heavy rains of 50 to 80 mm from Elm Creek through Starbuck and La Salle to Landmark. (see map below) The showers and thunderstorms this morning are a prelude to what is expected to be a wet weekend over the Red River valley with additional showers and thunderstorms through Saturday into Sunday that threatens more heavy rain. This will elevate local flooding concerns if the heaviest rainfall occurs in areas already hit hard by heavy rain today.
