Another round of rain..
WPC 24hr rainfall forecast (in inches) valid Wed to Thur evening
Another storm system is forecast to track across the Dakotas tonight and across SE Manitoba Thursday bringing another round of wet and possibly stormy weather to southern MB. Scattered showers and thunderstorms in advance of the system will push across southern Manitoba this evening and tonight before a steadier area of rain pushes across western MB through the Interlake overnight through Thursday. Locally heavy rainfall is possible within this band, with amounts of 25 to 50 mm possible in some areas by Thursday evening. Heaviest rainfall is expected in southeast SK where up to 70 mm of rain is forecast by Thursday evening. Here in Winnipeg and the RRV, lesser amounts of rain are expected.. on the order of 10-20 mm, however locally heavy downpours are possible with any thunderstorms that track though tonight especially near the US border. Rain will taper off Thursday evening across the Winnipeg area with clearing skies by Friday. Note also that strong northerly winds gusting to 70 km/h or more are expected behind this system by Thursday evening which may cause shoreline problems on southern ends of Lake Manitoba and Winnipeg Thursday night due to high water levels. Sunny and seasonable weather is expected Friday into the weekend with a warming trend for Sunday and Monday as temperatures rise towards the mid 20s again. Unfortunately, the warmup looks short lived as another system tracks through Tuesday with more showers, and a change to much cooler weather for mid to late week next week. In fact, it's possible southern MB may be seeing its first frosts of the season by the end of next week.
