A ridge will keep central Indiana mostly sunny Tuesday and limit thunderstorm chances for south despite the proximity of fronts. A short wave over the plains moves east-southeast Tuesday night to bring more thunderstorms late Tuesday and Wednesday. Turning cooler through the period with another cold front Thursday.
