A storm system is expected to move through the Ohio Valley Tuesday night and Wednesday, bringing windy and colder conditions, along with accumulating snow. Rain and possibly a few thunderstorms will develop Tuesday night. By late Tuesday night and into Wednesday morning, colder air moving into the area will change the rain to snow. At this point, it appears the northern sections of central Indiana will see the most snow from this system, where several inches of accumulation are possible. Lower snowfall amounts are expected farther south.
