Light precipitation moves in later tonight and departs around mid-morning Tuesday. Whether it falls as drizzle, freezing drizzle, or snow hinges on the EXACT combination of multiple factors that are difficult to pin down. Any icing amounts will be light and are most favored over northeast Iowa into southwest Wisconsin. Bottom line, if you have travel plans tonight into Tuesday morning, keep an eye on the forecast and road conditions as any amount of ice could turn roads slick.
Above normal temperatures return to the forecast with highs each day continuing to warm up slightly. Some light drizzle/freezing drizzle will be possible tonight and Tuesday night but temperatures by midweek should warm enough to keep all precipitation chances Wednesday and beyond as rain. Accumulations through Thursday will be light overall with overall rain chances increasing by Friday where more significant accumulations look to be possible.
