Updated Rainfall vs Normal Since Early May

The first two weeks of May ended up above normal with the exception of Lake, Ashtabula and portions of Geauga counties. Rainfall averaged more than 1" above normal for 60% of the area.



Between May 15 and 31st conditions dried out significantly. More than 1" below normal during the second half of May for most areas.


The first week of June the frequency of more hyper-local rainfall has gone up.  Deficits are still widespread as of this writing (June 7).


This week, the Sonoran High (western ridge) and the Bermuda High sandwiched the central US low which has stalled allowing for disturbances to rotate around the low and into the Ohio Valley producing frequent afternoon/evening slow moving storms. Animation is from Monday through Thursday.


Dewpoints reached 70 for the first time this year.
