around Superior. Westbound lanes on Highway 2 in Superior have
opened to two way traffic. There still are several road closures in
effect, please go to DouglasCountyWI.org or www.511wi.gov for more
detailed information. Please continue to follow all detours and road
closures.

The river gauge south of Superior has crested and continues to
recede as of 4 PM CDT. Around midnight the Nemadji River crested at

dangers of flooding.

For up-to-date road closure information visit DouglasCountyWI.org or
www.511wi.gov.

Please report flooding to your local law enforcement agency when you
can do so safely.

Road closures

Several roads and highways remained closed due to washouts from the heavy rains and flooding:

 

Highway 48 at the St. Croix River in Pine County is also closed due to a washout, according to MNDOT.

Check with the Minnesota Department of Transportation  or the Wisconsin Department of Transportation for the latest road closures.

Rain chances

Thankfully, there isn’t any heavy rain expected in the northland the next couple of days.

There will probably be some occasional scattered showers and even a few thunderstorms in the southern half of Minnesota into parts of Wisconsin Monday night into Tuesday, with a smaller chance on Wednesday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Monday night through Wednesday:

NOAA NAM simulated radar from Monday night through Wednesday, via tropicaltidbits

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of rain.

Temperature trends

Highs will be mostly in the 70s Tuesday, with a few spots reaching the lower 80s far north:

Twin Cities metro area highs are expected to reach the lower 80s Wednesday and Thursday, upper 70s on Friday.

I hope that you have a good week!
