Mostly sunny skies statewide today and we expect a warmer afternoon. South winds will develop though the day which will fuel the warmer surge. Clouds will be on the increase tomorrow, but for the time being, we think that we stay rain free.
Thursday, a few scattered showers dance through Ohio, but they really don’t have much available moisture to send our way, at least through the daytime hours. Coverage will only be 25%, and we can see clouds mix with sunshine in areas that do not get an isolated shower or two. Moisture really ramps up Thursday night. Rain and thunderstorms Thursday night through Friday end up hitting 70% of the state with totals in a wide range, from .1”-1. The heavier totals will be largely dependent on thunderstorms.
The weekend looks pretty nice, at least for 90% of the time. We are partly to mostly sunny Saturday, and then sunshine starts Sunday before clouds increase. Scattered showers develop over the western half to third of Ohio Sunday evening and continue through the overnight. Moisture totals once again do not look that impressive, at a few hundredths to .3”, but we really don’t need anymore moisture! Scattered showers linger over 60% of Ohio Monday, bringing an additional quarter of an inch or less.
Strong south winds arrive for next Tuesday and will bring in much warmer air. This air will lead to an increase in instability and provide fuel for a significant thunderstorm outbreak Tuesday night. Sun will be followed increasing clouds Tuesday, also signaling a big change. Rain and thunderstorms come in Tuesday night and continue through Wednesday. Rain totals look to be from 25″-1″ with 90% coverage. Thursday turns out partly sunny but turn cooler. The map at right shows 10 day cumulative rainfall potential.
The extended period still has rain for Friday the 24th, mostly in the afternoon and evening. Totals will be from .2” to .5” and coverage will be 80%. We are dry for the start of the Memorial Day weekend Saturday and Sunday. However, Memorial Day itself now looks wet, with rain and thunderstorms for Monday the 27th, and those run right into Tuesday the 28th. Rain totals run from half to 2” and we expect 100% coverage for the event. Finally, we end the extended period with a partly sunny, dry day for Wednesday the 29th.
