7 PM UPDATE:
We are starting to dry out after a cold front brought one last downpour to the Miami Valley. Through the event, Bellefontaine picked up 2.14 inches of rain and Dayton recorded 1.27 inches of rain. We now have a surplus of 1.89 inches for the month of May. There is still a 1.54-inch deficit for the year in Dayton.
Behind this cold front we will continue to see wind gusts around 20-30 mph through about 10 p.m. After that the wind will begin to calm. The skies will begin to clear and temperatures will fall into the 30s.
A Frost Advisory is in place for all of the Miami Valley except Warren and Clinton County. Frost formation is likely and sensitive plants should be covered. There’s a low risk for frost Monday night and a higher risk again on Tuesday night as temperatures stay well below normal.
