Columbus Forecast

Friday Forecast

Overnight: showers, chance of thunderstorms, cooling to the upper 50s by morning. Friday: showers, chance of thunderstorms, cooling to the lower 50s by evening, wind north 12-19 m.p.h. Friday night: showers, chance of thunderstorms, low in the mid 40s. Saturday: showers, chance of thunderstorms, high in the lower 50s, wind northeast 11-17 m.p.h.

Discussion

A cold front will move slowly across Ohio during the overnight hours. Showers and thunderstorms will move over the state behind the front. Northerly winds will transport colder air over Ohio after the front passes. A surface low over western Tennessee will move north along the front toward Ohio on Friday. Convergence into the low will enhance rising motion and showers and thunderstorms will continue to develop. The surface low and an upper low will be over Ohio on Saturday. Cold air in the upper low will make the air more unstable and the chance for showers and thunderstorms will continue.
