Chillier on Saturday; no soaking rains in the forecast

River flooding and overland flooding due to snowmelt have caused several road closures in Minnesota.

Don't even think about driving around the closure barriers. Here's a cautionary tale from Lac qui Parle County in western Minnesota Thursday:

Just 12 inches of moving water can carry away a small car:

Rain/snow chances

Most of Minnesota hasn't seen significant rain or snow in the past two weeks. The dry spell is welcome, as many rivers are at moderate or major flood stage.

Northern Minnesota could see some scattered rain and snow showers Friday afternoon into Friday night. The showers are expected to break up a bit as they move into central Minnesota Friday evening.

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

As always, updated weather information can be heard on the Minnesota Public Radio Network, and you’ll also see updated weather info on the MPR News live weather blog.

Minnesota could also see some rain/snow showers late Sunday and Sunday night.

Some rain showers will be possible across much of Minnesota and western Wisconsin next Wednesday and Thursday.

Temperature trends

Most of Minnesota and western Wisconsin will see highs in the 40s Friday afternoon. The metro area should top out in the upper 40s. Our average Twin Cities high temperature is 48 degrees this time of year.

Saturday will be breezy, with highs in the 30s in most spots:

The Twin Cities metro area could touch 40 degrees.
