With warm temperatures and dew points around 70°, the atmosphere will become increasingly unstable this afternoon. Scattered thunderstorms are forecast to develop by mid-afternoon across east-central Ohio.
There is a low chance that some storms today could be severe. The Storm Prediction Center has highlighted all of east-central Ohio in the Marginal Risk (1/5) for severe thunderstorms. A Marginal Risk is the lowest risk classification used by the SPC.
The primary concerns today will be damaging wind gusts and a potential for strong downbursts. Hail and heavy rainfall will also be possible.
The best time for thunderstorms in our area will be from mid-afternoon through this evening.
Otherwise, expect very warm temperatures and humid conditions today across the Valley. Afternoon highs will reach the upper 80s and with the humidity, heat index values will be in the low 90s.
Chances for a shower or thunderstorm will continue overnight and Wednesday. Severe thunderstorms are not expected tonight or Wednesday.
