Areas of frost early Monday; warming trend this week

We all know this spring-time drill.

Temperatures are expected to drop into the 30s across most of Minnesota and western Wisconsin late Sunday night into early Monday morning.  You can cover your flowers and tender outdoor plants before going to bed Sunday night. Some people bring small potted plants indoors to protect them from frost.

Frost advisories cover much of Minnesota (including the Twin Cities metro area) and parts of western Wisconsin from 1 a.m. to 8 a.m. on Monday:

NWS Twin Cities

Traverse and Big Stone counties of west-central Minnesota will be in a freeze warning from 1 a.m. to 9 a.m. Monday.

Temperature trends

Temperatures recover nicely Monday afternoon, with highs in the lower 60s across much of Minnesota and western Wisconsin:

It’ll be a nice change from our chilly weekend temps, but we’ll still be on the cool side of normal. Our average high temp is 71 degrees this time of year in the Twin Cities metro area.

Twin Cities metro area highs are projected to reach around 60 degrees on Tuesday, followed by lower 70s Wednesday. We could reach the mid to upper 70s Thursday and Friday.

Snow northeast

Duluth airport reported 2.4 inches of snow Sunday.  The Duluth harbor weather station reported mostly rain all day. Parts of far northwestern Wisconsin had already reported several inches of snow by Sunday evening:

You can check snow reports as they are posted by the NWS. If you hover over any point on their map, it will show you the exact location and time of the snow measurement.

A rain/snow mix will continue Sunday evening around Duluth and southward into Pine county as well as portions of northwestern Wisconsin.  Higher elevations in far northwestern Wisconsin could see mainly snow.

You can check for forecast updates from the National Weather Service office in Duluth.

Tuesday rain

Rain is expected to move into Minnesota and western Wisconsin on Tuesday and continue in some locations into early Wednesday. The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from Tuesday through Wednesday morning:

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.

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.

I hope that you have a good week!
