A very chilly air mass, the coldest of the autumn season so far has settled into southeast Wisconsin. Low temperatures tonight will be in the teens inland and low-twenties near Lake Michigan. Skies become partly cloudy tonight with a major pattern shift leading to an extended period of dry weather and sunshine which begins tomorrow and could last through the rest of the week and next weekend. Tuesday will be very cold with high temperatures in the upper-thirties with plenty of sunshine. A gradual moderation in temperatures begins midweek and we could see fifties by Saturday, in time for deer hunting.
