Snow will overspread the state today, with some significant lake effect snows in the northeast quadrant of Ohio. Snow coverage may not be quite as significant with 60% coverage of at least some snow, but the 2-5 inch totals in NE Ohio are still right on target, and will be around already this morning. While the snow tapers off in intensity and coverage this afternoon, we expect some hit and miss snow flurries to be around through the overnight and in spots even for the first half of tomorrow.
However, our next clipper is in faster, with snows developing Wednesday afternoon and going into early Thursday. We are increasing snow coverage to 80% of the state, and we will ride with 1-4 inch snows from NW Ohio across central and eastern parts of the state. Areas that do not see the 1 inch total can easily see a coating to an inch. This will be a nearly statewide event. But, since it comes in faster, it is likely gone faster as well. There should not be any new falling snow around anywhere in the state shortly after sunrise Thursday. The map above shows cumulative snow through Thursday midday.
Friday and Saturday look more active now, and we see several waves of snow moving through. We could add another coating to 2 inches over about 60% of the state those two days combined. SW parts of the state have the best chance of missing out, and also have the best chance of seeing temps climbing a bit higher for the period. Still, we look for less moderation in temps, as cold air looks to reassert itself.
Sunday afternoon into Monday we have another low moving through. This wraps some warm air up in front of it, but has significant snow potential on the backside. So, we can see a few hundredths to tenth of rain in southern and eastern Ohio Sunday afternoon, and then 1-3 inches of snow on the backside of the low Sunday night through Monday over the state.
We then turn a little drier for later Monday afternoon through midweek. Temps remain normal to slightly below. While we do see a large part of the state trying to climb above freezing, we do not see as strong of southwest flow now and think that any bump in temperatures will be minor. Lake snows and strong north winds are back by Thursday, and temps head back down.
The extended period still shows plenty of cold air, and we look for snows around the 21st into the 22nd. There should be good coverage over the state, but the question remains concerning any liquid that may try to mix in. Behind that, we are dry through Christmas weekend, with snow trying to develop out of an upper level low coming through the great lakes Christmas night into the 26th.
