Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Mostly cloudy skies will be the foretell of a cold front that will swing through tonight. This will set the stage for a low pressure to develop just South of the Ohio River by tomorrow morning. Light snow will develop along Us 35 and points South by mid-morning. Areas South of US 35 will see the best chance for 1 to 2 inches of snow tomorrow. Near the Ohio river into places like Cincinnati there could be 2 to 4 inches of snow. Temperatures behind this system will fall into the lower teens tomorrow night causing area road ways to become very slick. Saturday will be colder as a another weak low moves in from the NW late in the day and overnight. A few locations Saturday night could see up to an inch of snow from this system. Sunday a warm front will begin to lift North bringing temperatures closer to freezing by late day. Monday a low pressure will bring warmer air in and allow rain showers to move into the region.
It still looks likely that very warm air may move in by Thursday, however warm air over snow pack and cold ground comes the possibility of fog and drizzle. A storm system by late week may bring heavy flooding rains on top of frozen ground and this could cause problems. Stay tuned.
