Ohio Ag Weather and Forecast — May 15, 2018

An active pattern continues through the next week to 10 days. In fact, we have expanded our active pattern to have rain chances somewhere over Ohio for 7 of the next 10 days. That’s right, only 3 full dry days are dry over the next 10 days!

Showers and thunderstorms move across the state today. Action kicked off last night with thunderstorms moving into NW Ohio. The shower and thunderstorms today will end up with 80% coverage of the state, and we look for rain totals to be mostly from .25”-1”. Thunderstorms can be strong later today in east central Indiana, leading to some 2”+ rain totals on an isolated basis.

The moisture works south overnight tonight through tomorrow. Tomorrow will have most of the showers staying south of I-70, while the northern half of the state gets a bit of a break. However, down south, we likely see a few hundredths to .3” with 70% coverage south of I-70. The best rain totals will be in southeast Ohio tomorrow.

Thursday is our first dry day for the state. We should see good sunshine and temps above normal.

Moisture moves back into the state on Friday, surging up from the south and southwest. Then scattered showers hold in over the state through Saturday and Sunday. Coverage is not all the spectacular each day (60% Friday, 50% Saturday, 60% Sunday) but we all likely see rain at least a once or twice through that period. Combined rain totals will be from .3”-1”

Monday features some carryover from the weekend rains, but totals are minor, and coverage will be less than 30%. WE can see up to an additional quarter inch of rain with the best coverage in the far south.

Tuesday and Wednesday will be mostly dry, our second and third (also final) dry day of the 10day period the state. Our next wave shows up overnight Wednesday, the 23rd and hits most of Ohio through the 24th. That system brings .1”-.6” over the state, with coverage at 70% of the state.

So…we have plentiful moisture through the next 10 days. The map shows cumulative 10-day totals for all of Ohio. Temps over the next 10 days remain mostly normal to above normal. The warmer temps will help to fuel better thunderstorm development…which is one reason some of our precipitation ranges are wide in our forecast. The key takeaway, though, is that we have very very minimal chances of seeing any kind of back to back dry window to work with for field work over the next 10 days. We still think we can dry down in the 11-16 day forecast window, as high pressure works in from the NW.
