Moving into Wednesday, ridging over the western CONUS will broaden and approach the mid-Mississippi Valley region. This will increase temperatures back to near normal in the upper 80s. At the surface, high pressure will push off to the east and a warm front will move into the lower Ohio Valley. This front will bring increased moisture and lift to broad upper troughing. Looking to see isolated to scattered chances for showers and storms on Wednesday over southern and central Kentucky. Forecast soundings show PWATs around 1.7-1.8 inches, weak shear, and ample instability Wednesday afternoon. Though, mid-level lapse rates look poor. Given this environment, we could see a strong pulse storm or two, but severe weather is not expected at this time.

On Thursday, a shortwave will swing through the Great Lakes region and bring a weak cold front through the Ohio Valley. Current timing of the front is Thursday into Friday. Given the antecedent environment, would expected to see scattered showers and storms along and ahead of the cold front.
