Wednesday PM Update:
A fast moving storm system will bring messy weather for the upcoming and last full Christmas shopping weekend. There is a small chance that it will include wintry weather for parts of the Local 6 area but most of the precipitation will come in the form of rain showers and a few thunderstorms.
Very cold air will be in place Thursday but then milder air will begin to push in Friday during the day giving us highs in the 40's. By sunset Friday, temperatures may briefly drop into the 30's and lead to the advancing rain mixing with a little sleet, mainly in Missouri. All precipitation will turn to rain as temperatures then rise to near 60 degree during the day on Saturday. The cold front will then approach Saturday evening bringing the highest chance for showers and thunderstorms, then arctic air to follow. This is when rain showers may turn to snow showers as the colder air arrives behind the front overnight. Where snow showers persist, a coating will be possible to mainly grassy and elevated surfaces. With temperatures also plummeting into the 20's, patchy black ice will also be possible.
