Precipitation chances

Western Wisconsin could see some showers today.

Northeastern Minnesota and northwestern Wisconsin have a chance of rain-snow showers Tuesday night into Wednesday morning.

Looking ahead, northern Minnesota could see rain showers on Thursday, which then mix with or change to snow Thursday night and continue into Friday.

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential precipitation pattern Thursday through Friday morning:

Green indicates rain and blue indicates snow on the loop.

Temperatures in the lowest couple of thousand feet above the ground will be very important in determining how soon the rain changes to snow.

Northern Minnesota and northwestern Wisconsin could see some accumulating snow Thursday night into Friday morning.

In the Twin Cities metro area, the rain could change to a rain/snow mix Thursday night into early Friday.

Some light accumulation on grassy areas is possible in the northeast metro early Friday morning.
