We transition to a wetter pattern today. The thing is, a large part of Ohio will end up with not much action today. The front heading toward us is a slow moving front, which is part of the reason it has developed so strongly. Showers start to nose into far NW Ohio around midday, and will spread a bit through NW and west central Ohio into the evening. The true significant rain and thunderstorm action spreads across Ohio tonight through Friday and another round Saturday. Rain totals for that period will become in at .75″-2.5″. It will be a very wet period with rain coverage at nearly 1o0% of the state. Winds bump up tomorrow and will stay strong into the start of the weekend, drawing down much colder air. Temperatures tomorrow will be 10-20 degrees colder than yesterday and today. The map at right shows cumulative rain potential for today through Sunday morning. Clouds hold over most of Ohio even on Sunday on the backside of this system, but we might be able to break some sun through late.
Scattered showers return to start off next week. Rains on Monday will yield .25”-.75” as a front sags across the state. This will bring 80% rain coverage. Tuesday rains linger in southern and southwest Ohio, bringing a quarter of an inch or less, with only 30% coverage. The rest of the state sees a mix of clouds and sun. Wednesday, clouds build again, with rains in the afternoon and through Wednesday night from US 30 southward. This batch of moisture produces .1”-.5” rain totals with coverage at 70% of the state. All told, the rains can easily be over an inch for the first 3 days of next week combined…and again we see no significant drying.
We finish the 10 day forecast window with partly to mostly sunny skies next Thursday and Friday. Saturday the 27th we see a few scattered showers with the potential for a few hundredths to .25” of rain and coverage of 60% of the state. Then we have 2 more dry days with sunshine Sunday (28th), and sun followed by late day clouds on Monday the 29th.
Rain returns for Tuesday the 20th and there is potential for half to 1 inch totals. The rains linger Wednesday morning, May 1st, in northern and northeastern parts of the state, but we expect clouds to give way to sun over the rest of the region. Sunshine remains the dominant feature to finish the extended window for Thursday and Friday the 2nd and 3rd, but cooler air is also coming back. In fact, we are watching Thursday night into Friday morning closely (the overnight of the 2nd), as we think there could be some frost potential there. Stay tuned.
