After a cold and wet April, May is shaping to have temperatures normal or slightly warmer than normal with rainfall near normal.
Except for rainfall later this week (with best chances north of I-70) rainfall will be at or below normal for the first half of May. The exception will be the northern tier of counties in Ohio which should at least get normal rainfall maybe a bit above.
It does appear the second half of May will turn somewhat wetter which should cause May to average out the drier and wetter patterns to near normal rainfall.
With more drying and warmer temperatures, that is some good news in Ohio for getting crops going in a big way.
The NOAA/NWS/OHRFC 16-day rainfall maps shows the highest risk area for 2-4 inches of rain the next few weeks from extreme northern Ohio into northern Indiana back into Illinois and Iowa.
