Tonight into Friday night
A 1025 mb surface high, currently over the western Dakotas and eastern Montana, will gradually build east across the Upper Mississippi River Valley. Skies will gradually clear tonight and then this high will provide mostly clear skies and light winds into Friday night.
Low temperatures tonight and Friday night will range from the mid- 30s to mid-40s. There may be some patchy to areas of frost in central and north-central Wisconsin. High temperatures on Friday will be in the lower 60s.
Saturday and Saturday night
A Canadian cold front will approach the area from the Northern Plains on Saturday and then move southeast through the area on Saturday night. There should be enough moisture convergence for a few showers to form along the front north of Interstate 90.
High temperatures will be in the lower and mid-60s. Low temperatures will range from the lower 40s to lower 50s.

High pressure will provide dry weather. High temperatures will be in the lower and mid-60s on Sunday and Monday, and in the mid- to upper 60s on Tuesday. Low temperatures on Sunday and Monday nights will range from the mid-30s to mid-40s. There may be some patchy to areas of frost in central and north-central Wisconsin.
