Severe Storms For The Northeast U.S..; Heat And Fire Out West

A strong cold front will likely trigger severe thunderstorms and locally heavy rain on Friday from the Interior Northeast into the eastern Ohio Valley and northern Mid-Atlantic region, especially in New York state and Pennsylvania. Meanwhile, in addition to the ongoing heat wave in the West, fire weather concerns are increasing across the Great Basin into the Four Corners region. Read More >

This was a busy month for meteorologists in the Ohio Valley! Many rounds of thunderstorms rolled through the region, and on nine days of the month those storms were severe. There were 69 instances of severe weather reported across those nine days, mostly in the form of damaging wind gusts. Only two storms produced large hail, with one of them dropping hailstones the size of golf balls just north of Gamaliel in Monroe County on the 8th.

Rainfall amounts varied widely, with western parts of the region receiving much more rain than eastern sections. From Hoosier National Forest to the Bowling Green region 600% of the normally expected amount of rain in July fell. Bowling Green recorded the wettest July ever seen there. The Green River at Woodbury crested 7 feet above flood stage on the 9th. Meanwhile, the west side of Louisville and the northern Blue Grass counties north of Lexington were near or even a bit below normal.

The purple colors on this map show where extremely heavy rain fell during July. Western Kentucky was especially hard hit.

 

The heaviest rains during the month at Bowling Green fell on the 6th and 28th. Frequent thunderstorm activity throughout the month resulted in Bowling Green's wettest July on record.
