.Short Term Forecast...

Tonight and Friday (October 6-7)

Big weather changes on the way!

Clouds will be on the increase early to mid evening with rain developing as it spreads SW-NE into the Northland.

Rain continues overnight but as temperatures fall, rain will mix with and change over to snow in parts of north central and northeast Minnesota.

A few thunderstorms are also possible tonight mainly over eastern Minnesota and northern Wisconsin as elevated instability increases tonight.

Low pressure is forecast to track from north central Kansas to west central Lake Superior by daybreak Friday.  This is a very dynamic but also a quick moving storm so its effects won't stick around very long in our area.

Winds will shift around a bit through Friday with directions going from southwest to north-northwest and then back to the west or southwest.  Wind speeds 10 to 20 mph but higher gusts are expected.

Expect a few more rain showers Friday afternoon mostly over northern portions of Minnesota.
