As skies start to clear tonight temperatures will begin to plummet. Lows around most of southern WI will drop into the low 30s causing a frost tomorrow morning. A few of our northern counties including Juneau, Adams, and Marquette will see lows in the 20s causing a hard freeze.
Expect a rather cool Saturday with mostly sunny skies early with increasing afternoon clouds. Highs will range from the low to mid 50s.
Showers will be possible as early as Saturday evening across extreme SW WI near Platteville with rain becoming likely tomorrow late night for everyone.
Showers will last into Sunday morning, but I expect a decent break in the rain during Sunday afternoon. Highs will make in to near 60 degrees with more rain expected Sunday night into Monday morning.
