Ohio Ag Weather and Forecast, May 9, 2019

A few tweaks to the forecast today, but we are not changing the total number of events coming through. Our biggest event is here today. After seeing temps spike yesterday, we have truly energized the atmosphere and given plenty of ammunition for today’s front to shoot off fireworks. Rain and thunderstorms will arrive later this morning and midday, then spread across the rest of Ohio through this afternoon, tonight and the first part of tomorrow. We are going to increase the upper end of our rain totals for this event thanks to slightly better thunderstorm chances tonight, but in all honesty the best thunderstorms fire off to our west in Indiana. So, look for rain totals of .25”-1.25” with the upper end of the range heavily dependent on thunderstorms

Friday afternoon we start to see some clearing, and end up with a mix of clouds and sunshine; It will be cooler behind the frontal boundary passage. There should be good evaporation, although we may not quite attain maximum levels. Winds will be strong from the north and northwest. Clouds build again on Saturday, and our next round of precipitation arriving faster. Showers develop Saturday late afternoon or evening and continue through a large part of Sunday. The thunderstorms happen overnight Saturday night and Sunday morning, then the rest of Sunday scattered showers end and clouds take a while to break up. We can see some afternoon sun over the western third of Ohio Sunday.  Rain  totals from the entire event will be from .25″-1.5″ with coverage at 80% of the state.

We return to dry weather Monday and Tuesday. Sunshine should dominate through that period. We are pushing our next system back a day, arriving Wednesday late morning to midday There we see  scattered showers yielding a few hundredths up to .4” over 90% of the state. Dry weather with partly to mostly sunny skies finishes out the 10 day window for Thursday, Friday and next Saturday. Temps will be near normal. The map at right shows rain totals through the next 10 days.

In our latest look at the extended 11-16 day window, we remain confident that we have a couple of dry days to start. Showers arrive late on the 20th into the 21st and are on track for .25”-1” with coverage at 70%. We may see a few showers linger into early the 22nd with 30% coverage, mostly north.
