Rochester, MN (KROC-AM News) - Here we go again. The National Weather Service says portions of southeastern Minnesota are in the bullseye for a potent winter storm which is expected to pull even colder air into the region later this week.

Fillmore and Houston Counties are included in a Winter Storm Warning that also covers parts of northeastern Iowa and a portion of southwest Wisconsin. The rest of southeastern Minnesota, including a section of south-central Minnesota, and a wide area of Wisconsin are under a Winter Weather Advisory. Both the warning and the advisory have been posted from midnight Monday through midnight Tuesday.

Areas of snow are expected to develop late tonight and continue into the evening on Tuesday. At this point, the National Weather Service is predicting the Rochester area and others included in the Winter Weather Advisory could see 3-6 inches of new snow by tomorrow night. The snowfall totals in the warning area could be as high as 8 inches.

The responsible low-pressure center is then forecast to pull in a mass of Arctic air that could push the low-temperature readings into the teens below zero early Friday when the high temperature may not even reach zero. It is predicted to warm up slightly for the weekend with highs from 5 to 10 above zero.
