Areas of dense fog will reduce visibilities to 1/2 mile or less this morning. In areas where there is dense fog, reduce speeds and increase distance between the vehicle in front of you.
Rain will transition to snow tonight into Wednesday with winds picking up out of the west/northwest. Areas along and north of I-90 have generally between 1 to 3 inches possible, with the highest amounts towards north central Wisconsin. Snow is expected to be light and fluffy so the wind will likely cause it to blow around though it shouldn't be enough to drift. The Wednesday morning commute and holiday travel will be impacted.
Winds out of the northwest will increase late Tuesday night into Wednesday with gusts between 40-45 mph possible across the region. There is also a low chance (15 to 25%) for gusts over 50 mph. This, coupled with falling snow early Wednesday, could create reduced visibilities which impact the Wednesday morning commute and holiday travel along and north of I-90. Be sure to give yourself extra time on the roads.
Along with the chances for rain and snow, temperatures are expected to plummet Wednesday with high temperatures in the 20s to low 30s and lows in the teens to low 20s. Subsequent wind chills will be the coldest of the season with single digit to near zero apparent temperatures Thursday and Friday morning.
