Thunnderstorms???

Highs will top out at 53 today as spring like air mass moves in. Given shear and some CAPE, isolated thunderstorms are possible this evening. There is a marginal severe threat for Southern Indiana. Isolated hail is the main threat there. Rain/thunderstorms look to start shortly after nightfall tonight. (6-8p.m.) Temps tonight will hover in the mid to upper 40s. Colder air will move in tomorrow. Minor accumulations are expected. More on this later.
