Through 2 AM, widespread rain continues with freezing rain building in north of I-90 as temperatures cool. Precipitation stays rain for areas south of I-90. Where temperatures are at freezing, ice may begin to accumulate on elevated surfaces. Road temperatures remain in the mid to upper 30s so not expecting any road impacts in the near term but will keep an eye out as the night progresses.
A winter storm moves through the region tonight into Thursday, leading to a belt of freezing rain in west central to central Wisconsin. Moderate to high impacts to travel are expected tonight into midday Thursday. Adjust plans now.
In addition to our freezing tonight, the upcoming storm system brings a risk for severe thunderstorms to southwest Wisconsin and parts of northeast Iowa. Hail and damaging winds are the primary risks with secondary risks of localized flooding and a tornado possible.
Precipitation starts out at rain for most locations but then many locations along and north of Interstate 90 see freezing rain with occasional sleet overnight tonight. Tomorrow, conditions warm up, causing precipitation to switch back to rain with potential for thunderstorms in the afternoon.
Freezing rain is ahead for a good chunk of the region. This can be more dangerous than snow as ice can form on pavement, particularly on bridges and overpasses. Be alert for falling branches and powerlines. Avoid driving if there is or recently was freezing rain.
