Heavy rain is done in the west and central part of Ohio this morning, but we have rain holding on over the eastern third to quarter of the state. This rain will likely linger into midday before pushing east into PA. Cold air is rushing in on the backside of the moisture, driven by strong NW flow across the great lakes. Temps are shifting to well below normal levels, but honestly look to be a little bit better here than farther west in Indiana today. The northern half of Ohio will see temps in the 30s to low 40s, while the southern half of the state will push into the mid and upper 40s still. We likely see our coldest air overnight tonight. Adding insult will be strong NW winds, making it feel even colder. Light moisture holds over the state through the entire day, but there will be significant holes in the precipitation coverage. We are not looking at liquid equivalent being any more than a few hundredths to perhaps a tenth of an inch, but with temps being where they are, we have to allow for wet snow to fly over northern areas pretty much at will. And, we can see rain mix in too.
Tomorrow seems colder over a larger part of the state and looks to have more moisture around, particularly up north. The map shows temps tomorrow afternoon as compared to normal. From I-70 northward, we would not be surprised to see a coating to an inch of wet snow from midnight tonight through tomorrow. There likely is nothing developing farther south tomorrow. But, the chilly air is not leaving anytime soon, and we see clouds reluctant to break up in the south.
Dry weather is in for overnight tomorrow night through the bulk of Wednesday.
Our first tweak of the forecast (from last week’s thoughts) is to push our midweek action back slightly. While we now see most of Wednesday dry, clouds build late in the afternoon. Scattered light rain showers then break out closer to overnight Wednesday night and then linger though most of Thursday. Rain totals still look to be from a few hundredths to .25”, but we are increasing coverage to 80% of the state. The best rains will be from US 30 northward.
Dry Friday, Saturday and Sunday. This is our next slight change in the forecast – the dry weekend. Temps stay cool for the end of the week and start of the weekend, as we continue to see mostly NW flow dominate the eastern Corn Belt. However, on Sunday, winds turn more S and SW ahead of our next system for early next week. This should allow temps to moderate back closer to normal. WE do not expect a big push above normal, but still, Sunday will likely end up bringing the warmest temps of the next 7 days.
Clouds will slowly increase through the day Monday, but we should stay dry, while action develops off to the west. Our next system pushes into Ohio overnight Monday night into Tuesday morning. This low pressure circulation will be coming up from the SW. Scattered showers fall statewide through Tuesday and into early next Wednesday. Rain totals are expected to be around .25”-1” over 70% of the state. The heaviest action seems to set up through central Ohio, but this projection is nearly 10 days out…so a lot can happen between now and then.
We should be dry for the start of by Wednesday evening, and strong Canadian high pressure slowly sinks off to the southeast. That keeps the region dry for the night of the 25th along with the 26th and 27th, which is another forecast change, also in our favor. This should bring impressive southwest flow up on the backside of the high for the 27th. That southwest flow will warm us to near normal temperature levels. A cold front works in from the northwest for the 28th and 29th. Rains with that front remain in the half to 1” range with coverage at 80% of the state. Behind that we look dry for the remainder of the month into early may. However, that dry forecast is rooted in yet another Canadian high, so that means we likely see a cold finish to April and start to May, with temps a good 5-15 degrees below normal.
