The first frost of the season for Woodbury could arrive early Sunday morning, according to the National Weather Service.

The agency has issued a freeze watch from 1 a.m. to 8 a.m. Sunday for all of central and southern Minnesota.  

A “cold dome of high pressure” will move in behind a cold front Friday, according to the weather service. That will create clear skies and calm winds Saturday night, which will allow temperatures to fall as low as the mid-20s outside urbanized areas.

In the urban core, temperatures will likely be in the mid-30s, but frost is possible even if temperatures don’t dip below freezing.

A freeze watch means low temperatures that could kill crops and sensitive vegetation are possible.
