Scattered light precipitation moves across the state today, but really has very little moisture to truly work with. Right now we will look for a few hundredths to a tenth or two over 50% of the state. A lot of the moisture may end up coming out as clouds and spotty drizzle. Still, we can’t call the day precip free, even if action is very, very light. Better action develops overnight tonight into tomorrow. The best rains are south, and far NW Ohio may miss out on precipitation. However, we are leaving rain totals at .1” to 1.25”, and that upper end range total will be limited to areas near the river in south central Ohio. The heaviest rains remain farther south in KY, but probably do not move north with any regularity.
We are dry from Saturday afternoon to midday Sunday. Weak high pressure drifts across the state in that period and acts as a bit of a place holder in there while cold, arctic air starts to blast in. We should see some sunshine in there, particularly Saturday afternoon.
Sunday afternoon, snow arrives over the state. Northern areas have the best potential. Our official forecast is for 1-3 inches from I-70 northward. We won’t even rule out a 4 inch total here and there along the US 30 corridor and up into NE Ohio. But, farther south the snow never really materializes well, so a coating to half an inch is all we see in areas south of 70 where it snows, and a large part of southern Ohio may see no snow. Statewide coverage we will put at 60% for snow on Christmas eve. By Christmas morning, everything is clear of the state, and sunshine is trying to come back. The map above shows potential 24 hour snow totals ending shortly after sunrise Christmas Morning.
Dry Tuesday through Thursday with high pressure in control and cold air continuing to batter the region. Sunshine should dominate for Tuesday and Wednesday. Thursday night and Friday we have another push of snow for the state, with accumulations likely in the 2-4 inch range. Statewide coverage of snow will be 75%.
While cold air stays, we are starting to see our New Year’s Eve weekend storm event come back into focus. A strong low wants to lift northeast for next Saturday, the 30th. It has ample moisture with it, and could trigger significant snows over the state. Models have been flip flopping on this system for several days, so it’s nothing to get too super excited about yet. But, it is something we are monitoring, as it may send 2017 out with a flourish and start 2018 with a bang.
