Overview
- Louisville set a record at 75 degrees Sunday before temperatures crashed into the 20s Monday, with a wind chill as low as 4 degrees reported in the metro.
- A quick-hitting line of showers and thunderstorms Sunday night produced widespread 40–50 mph gusts and peaks near 60 mph along its path.
- Numerous alerts accompanied the line, including a tornado watch for Orange, Lawrence, Jackson and Jennings counties in Indiana during the evening.
- The strongest storms moved through between about 9 and 11 p.m., with the worst pushing east of the area by around midnight.
- Post-frontal winds kept Monday wind chills in the teens to single digits and prompted a wind advisory near Cincinnati, while forecasters now eye light New Year’s Eve snow of a dusting to roughly a half inch that could slick late-night roads.
