A few snow showers or flurries are possible Wednesday and Thanksgiving Day but little accumulation is likely.

By Thanksgiving Day, our temperatures will be more typical for January in Minnesota. 

Temperatures across Minnesota will bottom out Thanksgiving weekend. Overnight minimum temperatures will crash to subzero in the northwest with temperatures in the single digits south by the predawn hours of Saturday.

If next month is around normal, it will be the first real winter month in about two years given last winter was the mildest winter on record.

Welcome to what looks like a real Minnesota winter season ahead.
