The first freeze of the season is expected tonight

A freeze warning and frost advisory are in effect for much of the state.

Cover up those plants, the first freeze of the season is expected Monday night. 

The National Weather Service in the Twin Cities says much of the state could see temperatures at or below freezing overnight. 

The forecast shows highs on Monday ranging from the upper 40s in northwestern Minnesota to the lower 60s in the southeastern part of the state. 

But as high pressure builds across Minnesota Monday night, the sky will clear, helping create a "perfect set up" for frost and below-freezing temps, the National Weather Service says

The forecast has overnight lows will drop to the lower 20s in northern Minnesota, while far southeastern Minnesota will see temps in the upper 30s. 

Highs Tuesday will be in the 50s, the National Weather Service says. 

Freeze warning in effect

Chilly overnight temperatures have prompted the weather service to issue a freeze warning for much of the state from Monday night into Tuesday morning. 

This means below freezing temps are "imminent or highly likely," which will kill crops and sensitive vegetation. 

A frost advisory is in effect for the Twin Cities and much of south-central Minnesota. This means widespread frost is expected, so you should cover up sensitive outdoor plans or they may die. 

The only area that has escaped these chilly weather alerts is Rochester and the southeast corner of the state (see map below).
