A minor trough sags through the state today, triggering some clouds as it does. Precipitation is going to be limited from this, but we do still have to allow for a few hit and miss showers south of a line from Cleveland to Greenville with coverage of 60%. NW parts of the state end up with no new precipitation today. Tomorrow will be sunny and dry in all areas.
Thursday, rain spreads over most of the state as a cold front comes down from the north, and moisture lifts up from the SW, meeting over OH. We should see anywhere from a few hundredths to .5″ with coverage at 85% of the state. Only far NW areas will have a good shot at missing the moisture there. Significantly colder air comes in on the backside of that system.
WE are much colder for Friday and Saturday, with partly sunny skies likely both days. Sunday clouds increase and we can see some afternoon rain or snow showers over areas from I-70 north. Liquid equivalent precipitation totals are small, a tenth or two at best, but that still can keep a more damp feel, even if sloppy wet snowflakes decide to try and mix in. The best threat of wet snow would be in the overnight, as temps drop off.
Another surge of cold air takes our temps on another leg down to start next week. We will be well below normal Monday-Wednesday. The map at right are temps vs. normal around midnight Monday night. The purple is an area of temps 30-35 degrees below normal. That is brutal cold. We should see some sunshine off and on for Monday and Tuesday, but lake effect clouds and snow showers are possible over the state on Wednesday, mostly central and north. Mostly sunny skies are back for Thursday.
In the extended period, we have a chance of rain showers with moderating temps for Friday the 15th, bringing rains of .25″-.75″ to 80% of Ohio. Then drier, colder air returns for the 16th through 18th. Another strong system finishes out the 11-16 day extended period for Tuesday and Wednesday the 19th and 20th. Rains can be from half to 1.5′ with 100% coverage. So, our drier, potential harvest windows are better nearby than in the extended period.
