The forecast is less friendly this morning for parts of the state, as we are having to increase moisture potential. Here in the short term today, there is not much change. Most of Ohio will turn out partly sunny, but will remain cool with strong north flow. We will keep an eye out in NW Ohio for a renegade shower or two, trying to push in toward midday and early afternoon out of Indiana. Tomorrow we continue to watch as the offshoot moisture from a cold front to our west works in. However, we are leaving moisture totals along, with a clouds and a few scattered showers. Rain totals will be no more than .25″ and generally will be a few hundredths to a tenth, with 60% coverage (mostly north of I-70). Temps will be significantly warmer. Our first tweak of the forecast is to add more moisture for Thursday, as lingering showers hold across a large part of Ohio. We can see additional rains of a few hundredths to half an inch with coverage at 70%. Friday will turn dry again, but will stay warm.
Unfortunately, the weekend looks more active. We had been looking for rain and thunderstorms on 1 day out of the 3 day holiday weekend…now we are raising that to 3 out of 3 days. Showers and a few thunderstorms can be around each day Saturday through Memorial Day Monday. Coverage each day will be from 50-60%, but combined for the 3 day period we should see coverage closer to 80%. Combined rain totals will be from .25″-1″, with the potential for .1″-.4″ each day. Stronger thunderstorms should stay well off to the west and south. The map at right shows cumulative rain potential through Memorial Day next Monday
We get a dry day for next Tuesday, the 28th, as our next system is pushing back just a bit. Scattered showers arrive Wednesday the 29th, mostly from I-70 north, but they look less intense. For now, we are pulling moisture back to .25” or less with coverage at 75%. Dry to finish the 10 day window and start the extended 11-16 day period next Thursday and Friday (30th & 31st).
Sun on the first will give way to clouds and we see rain arriving that night. That rain continues into June 2nd with combined moisture totals of .25”-1” and coverage at 80%. We are projecting 3 dry days behind that to finish the extended period for Monday the 3rd through Wednesday the 5th. There could be another system on the way for the 6th.
