Low pressure passed across southern Wisconsin early this morning and will move across northern Lake Michigan and Upper Michigan during the day. This low pressure system brought periods of light freezing rain and drizzle to southern Wisconsin on Sunday and Sunday evening, before most of the freezing precipitation changed over to mainly rain.
For today, increasing west-northwest winds will carry colder temperatures across southern Wisconsin. This will change any lingering light rain and drizzle over to occasional light snow and flurries. Accumulations will remain light, mostly under an inch.
Temperatures will fall below freezing as the colder air sweeps in from the west. The below freezing temperatures could cause any untreated wet roads and walks to refreeze.
