A low pressure system is moving up from Texas this evening, allowing light rain to overspread the region. Temperatures will likely be cold enough across southern Indiana and north-central Kentucky overnight to allow for freezing rain. A Winter Weather Advisory has been issued for our northern counties tonight through 11 AM EST on Saturday where 0.1" to 0.25" of ice could accumulate. The map below highlights those counties affected by the advisory. The purple highlighted counties have already begun their advisory (as of 6 PM EST) and the other pewter highlighted counties will begin their advisory at 1 AM EST Saturday.
As the aforementioned low pressure system enters into the Ohio Valley, an increased chance for thunderstorms exists over the highlighted counties in the map below. Not only is there a chance for thunder to rumble, but a slight risk is in place for severe thunderstorms. The primary threat with any severe storms that does develop is damaging winds, although the possibility of an isolated tornado or small hail cannot be ruled out. Please stay well informed of the latest weather information throughout tonight.
