MADISON, Wis. (WMTV) - Sunday morning lows start off in the upper 30s and lower 40s. This morning’s Frost Advisory in Juneau/Adams counties expires after sunrise. However, another may be necessary tonight. So, if you pulled the plants in - keep them in for another night!

High-pressure moves over Wisconsin today into Monday. Highs return into the lower 60s under plenty of sunshine. A calm wind & clear sky overnight will allow lows to drop into the upper 30s and lower 40s again. Low-lying areas will be susceptible to frost development. Sensitive plants should be brought indoors.

After early sunshine, clouds grow late Monday ahead of an approaching low-pressure system. Scattered showers are possible late Tuesday - with the better rain chances arriving Wednesday. Moderate-heavy rain is possible. Rainfall amounts could top 0.5″-1″. This kind of rainfall would help offset our month & year-to-date rainfall deficit. Highs during this mid-week period will only top out in the upper 50s - near 60°.

The rain wraps up by Thursday with highs climbing towards 70°F on Friday. A warmer & more humid weekend is looking likely. A few showers are possible with a potential cold front bringing storms next Sunday.
