Heat wave will break with gusty storms and welcome rain


COLUMBUS (WCMH) — Our fourth day in a row with a high in the low 90s, coupled with high humidity, pushed the heat index to 100 again Sunday afternoon in Columbus, before scattered storms developed with locally heavy rain and gusty winds southeast of the city.

A slow-moving weak cold front over Indiana will be the focus for additional showers and storms tonight and Monday, some accompanied by gusty winds, frequent lightning and heavy rain.

Clusters of strong storms moved across northern Ohio Sunday evening, triggering numerous warnings for wind, flash flooding, and even a tornado warning for parts of Wood and Seneca counties.

The cold front will shift winds to the northwest as it sags south overnight from the lower Great Lakes across Ohio, ending the four-day heat wave, but will hang up as a low-pressure wave ripples east on Monday.

Temperatures will be markedly cooler (70s) Monday and Tuesday, then return to seasonable levels, but with comfortable humidity, under high pressure stretching from the mid-Mississippi to the Ohio Valley midweek.

Today is also the anniversary of the hottest temperature on record in Columbus (106 degrees), which was tied on July 14, 1936. These readings were observed during the Dust Bowl era, when scorching heat waves built eastward from the seared Plains, where overgrazing contributed to soil loss and heat absorption.

In southeastern Ohio, an all-time record high of 113 degrees occurred at Gallipolis on July 21, 1934.

Tonight: Showers and storms, sticky. Low 73

Monday: Showers tapering off mid-afternoon. High 78
Tuesday: Lots of sun, pleasant. High 78 (60)
Wednesday: Sunny. High 81 (58)
Thursday: Mostly sunny. High 84 (60)
Friday: Partly sunny. High 86 (61)
