Yet another snow system is crossing the state this today. Snows do not look overly impressive to the north and west, and we are leaving snow totals at a coating to 2 inches in NW Ohio. The strongest snows run through a widening channel centered on a line from Cincinnati to just north of Wheeling. In that area we can see easily 2-5 inches of snow, and perhaps more on the eastern side of the state. We also think we need to bend the bigger accumulations up into NE Ohio too, thanks to some lake enhancement. All told, most of the state sees snow this morning through midafternoon, and some of us will see a significant amount. Everything is done by mid to late afternoon, and we even expect sun to come out over western Ohio as the day wears on.
High pressure drifts over Indiana overnight tonight and will set up over southeast Indiana and southwest OH by tomorrow morning. This will bring colder air back, and we do expect some spotty subzero temps tomorrow morning, mostly in NW parts of the state
Our next snow event for Friday has shifted farther north. The best snows Friday spread across MI, but we think we have to keep snow in the forecast for far northern Ohio, and particularly action near or over the lake. Most of what we are keeping an eye out on will be north of US 20, but clouds and the odd bit of snow can drift down closer to US 30. Still, most of the state stays dry for Friday, and we actually see some pretty good warming for most of Ohio. Temps can be freezing or above all the way up to near US 20, and sun will be a dominant player south of I-70.
However, we do not escape the snows. What Mother Nature takes out for Friday, she puts in for Saturday overnight and Sunday. We now see a much stronger secondary wave coming for that period, 1-4 inches of snow to 90% of the state. We see much heavier snows to the west and north, so we really dodge a bit of a bullet here, but still, it is more snow for later in the weekend that we had been looking for. This is a new wrinkle. Previously, we had been looking at most moisture coming out in a warm front scenario on Friday, and little action with the cold frontal passage. In fact, the cold front was not as dramatic in terms of temperature change. This change moves the best precipitation to the cold front passage for the last half of the weekend. It also can lead to a larger coverage area for snow.
Bitter cold air is in for Monday. We expect subzero temps over most of the northern half to northwest quadrant of the state Monday morning. A slow moderation in temps comes for Tuesday, although temps stay chilly. Then Wednesday we see normal to above normal temps statewide, with most of the state above freezing for highs. Clouds are in for next Thursday, and we can’t rule out scattered light snow showers for next Thursday night (the 15th) into Friday, although the best chances for snow may be limited to the northern half to third of the state.
The extended forecast is unchanged, with only 1 threat of precipitation coming for the 19th into the 20th. The system still looks strong, and we think we can see up to 1.5” of liquid equivalent precipitation.
