Rochester MN (KROC AM News) - Minnesota will be returning to the deep-freeze this weekend. After a brief reprieve, old man winter is sending another mass of Arctic air into the region and forecasters are saying the mercury will likely not reach zero on Sunday.

The National Weather Service has issued a Wind Chill Advisory for most of the state of Minnesota. It will be in effect in the Rochester area from 3 a.m. until noon on Saturday with the “feels like” readings expected to be around 25 below zero Saturday morning. Even colder air is forecast Saturday night and Sunday. The actual air temperature is predicted to drop well into the teens below zero and the wind chill readings could be as cold as -40 Sunday morning.

At this point, forecasters are predicting a modest warm-up by the middle of next week with seasonable weather by the end of the week.
