Flood Watch Covers Thursday Morning

The National Weather Service has issued a Flood Watch through 2 p.m. Thursday for Franklin County and much of central Ohio. Multiple rounds of showers and thunderstorms could produce brief heavy downpours, with runoff affecting creeks, streams, low-lying areas and highway dips.

Showers and thunderstorms are possible from the morning into early afternoon, and the chance of precipitation reaches about 60%. Rainfall totals are not specified, but stronger or repeated storms could create locally higher amounts and sudden flooding.

Friday Brings A Brief Break

The alert ends Thursday afternoon. Friday should be cooler, with a break in rainfall expected later in the day.

Saturday is expected to be mostly sunny and climb to around 84. Thunderstorms are possible Saturday afternoon into Sunday evening.

Storm Chances Return For Sunday

Sunday looks unsettled, with showers and storms possible.

The weekend forecast remains active, while drivers should avoid flooded roads and never enter water covering a roadway.
