From spring to winter in less than 24 hours. After sunshine and highs near 70 today, cold front tonight will bring rain over to snow and much colder temperatures for the middle and end of the week.
Rain will change over to snow late tonight, and we could see some slushy snow accumulations on elevated surfaces. Most of what sticks will melt quickly, so any travel impacts will likely be limited to bridges.
Lows are expected to bottom out around 29-32 degrees tonight into Wed morning across southern Indiana, and Wednesday night-Thursday morning across most of central and eastern Kentucky. Since we're still early in the growing season, freeze conditions could kill or damage sensitive vegetation.
