Cooler temps return this week; soaking rains Tuesday

Frost potential later in the week

Weather didn’t interfere with our outdoor plans this weekend. We had plenty of sunshine and most of Minnesota had a dry weekend.

Temperatures will retreat a bit on Monday, then they will slide even more on Tuesday.

The average Twin Cities high temperature is 57 degrees on April 15. The metro area will see Monday highs in the upper 60s to around 70.

Monday high temperatures are expected to range from 50s in far northern Minnesota to 70s in the far south:

Soaking rains Tuesday and Tuesday night

The northern half of Minnesota will have the best chance of scattered showers on Monday, but an isolated shower is also possible elsewhere in Minnesota and in western Wisconsin.

A slow-moving low pressure system will bring periods of rain and some embedded thunderstorms to Minnesota, Iowa and Wisconsin Tuesday and Tuesday night. Some showers could linger into Wednesday morning.  

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) Forecast System model shows the potential precipitation pattern from 1 a.m. Tuesday to 4 p.m. Wednesday:
