Timing Friday night rain and thunderstorms in the Valley

Published 3:17 PM Friday, March 27, 2020

Rain showers and thunderstorms will move into the Valley overnight with a warm front associated with a low pressure system advancing out of the Plains toward the Great Lakes. Upper-level support will be greatest in southern Ohio initially early tonight and this will keep rainfall fairly light before midnight. However, support for heavy rainfall will increase through Saturday morning and chances for thunderstorms will become more prevalent along the frontal boundary as it travels northward.

SIMULATED HI-RES RADAR indicates several rounds of showers and thunderstorms are likely tonight in east-central Ohio. Rain can be heavy at times primarily after midnight especially in thunderstorms. Localized flooding will be possible tonight and Saturday.

Locally, heavy rainfall will be possible in any early morning thunderstorms. Training thunderstorms could bring 1 to 2 inches of rainfall tonight through Saturday morning. Odds for showers and thunderstorms will decrease Saturday afternoon as the warm front lifts north of the region.

Severe thunderstorms are not expected. However, a few strong storms may produce hail. Temperatures will remain mild through the overnight.

SEVERE STORMS POSSIBLE SATURDAY
A warm, moist and unstable atmosphere on Saturday will bring a threat for severe thunderstorms to our area. Updates regarding the timing will be posted later today. Damaging wind gusts and large hail are the primary threats with Saturday’s storms. The threat for tornadoes is low (2%) but not zero.
