...Short Term Forecast...

Tonight (September 15)

Low pressure will continue to move through the northern Plains tonight while a warm front lifts north out of southern Minnesota.  Occasional rain across the area tonight with a few thunderstorms also possible.  Lows will be in the 50s to lower 60s with south or southeast winds at 5 to 15 mph.

Friday (September 16)

An area of low pressure will move northeast out of western Minnesota while an upper level trough moves east into the Upper Midwest -- The combination of these features along with a cold front which will move through the Northland on Friday will lead to more rain chances.  A few thunderstorms are also expected tomorrow and there's at least a low risk for a strong storm or two but severe weather is not expected.  Highs will be in the 60s to lower 70s with lows in the 50s to around 60 degrees.  Winds tomorrow will be out of the south, southwest or southeast at 10 to 15 mph.  Winds tomorrow night will be out of the west or south at 5 to 15 mph.
