Ohio Prepares for Snowstorm, Cold Snap Grips Region. The calm of high pressure will briefly settle over Columbus and Cincinnati before a snowstorm sweeps through Ohio this Friday. The National Weather Service (NWS) has announced that high pressure moving northeast will offer cold but clear conditions today and tonight. However, foregone is the reprieve as an incoming storm system is expected to batter the area with snow from Friday afternoon into the night, inviting the high pressure’s return for the weekend.
