Temperatures were twenty degrees colder today but with the light wind and eventual sunshine, it was still a pleasant December day with highs in the upper 30s. Our clear skies will allow temperatures to fall into the upper 20s near Lake Michigan with low 20s expected inland. Clouds roll in by Saturday morning with a big storm system that will bring rain showers by midday with highs in the upper 40s. The heaviest rain and even a few thunderstorms roll in Saturday night and into early Sunday morning with just hit and miss showers through the afternoon with highs in the mid-50s. Rain totals will be highest in the north with most spots in southeastern Wisconsin picking up a half an inch to an inch of rain.
A light wintry mix of rain and snow is possible on Monday as the cold air starts to plunge in with a high of 40 degrees early, falling into the 30s by the afternoon with a strong wind. Skies will slowly be clearing on Tuesday with seasonal temperatures in the low 30s but we will stay dry for New Year's Eve with temperatures in the mid-20s at midnight.
