Another weak upper air disturbance will pass through the lower Ohio Valley tonight. Most of the dynamic energy is moving across the southern Great Lakes, but the heat and humidity over us has grown into a large concern for its thermodynamic energy contributions. As a result, an outbreak of thunderstorms looks likely for this evening and tonight. The Storm Prediction Center has us in a “slight risk” area for tonight; I’d prefer to use their soon-to-come Marginal Risk category. Gusty winds and some brief heavy downpours should move across the area roughly between 8 P.M. and 1 A.M. Chance for an isolated severe storm will be diminishing as the evening wears on.
Looks like the same story again tomorrow.
