While skies will be clear for many overnight, there will be an area of clouds develop and move south. Where those clouds form will impact overnight temperatures. For now, it looks like the best chance for frost is across NE and southern areas. Some frost could also form across the west. That's why frost and freeze alerts kind of make a U-shape around Indy.
Wednesday is another cool day across the Hoosier State. Partly sunny skies come with highs in the middle 50s. The wind will be lighter, so that will help.
Wednesday night into Thursday morning brings the best chance of widespread frost and freeze conditions to the area. After that, temperatures gradually moderate as we approach the weekend.
