A storm system will move through the Midwest early this holiday week. This afternoon will be cloudy and breezy with areas of fog and rain showers, possibly mixing with light snow at times. High temperatures will reach the upper 30s. Widespread rain and fog will continue tonight, and may mix with snow northwest of Madison. Temperatures will fall into the middle 30s by early Tuesday morning. As the low pressure system moves more northeast on Tuesday, areas of light rain, drizzle, and fog will persist. High temperatures will be quite mild on Tuesday, reaching 40 degrees. Rain will mix with or change to light snow Tuesday night.
As the low pressure system over Wisconsin moves to the northeast it will merge with another low pressure system moving up from the Gulf Coast. This will cause the merged system to stall to our northeast as it intensifies into Christmas Eve day. Christmas Eve will be cloudy and breezy with a chance for snow. A better chance for snow showers will stay east of Wisconsin. High temperatures on Christmas Eve should drop back to the middle 30s. Christmas Day will be variably cloudy and a bit breezy with highs reaching the middle 30s.
There is a chance for light snow Friday as another system moves through Wisconsin. Highs will reach the lower 30s.
The weekend will be quiet with partly sunny skies each day. Saturday will be breezy and colder with highs in the middle 20s. Sunday will be seasonably cold with highs in the middle 20s.
