Tonight, clouds will increase across the Tri-State as our weather pattern begins a noticeable transition. Temperatures only fall to around 71, with a light southerly wind helping bring warmer and more humid air into the Ohio Valley.
Wednesday stays mostly sunny and turns hot and humid, with highs in the low 90s and the heat index potentially climbing into the near 100s. The reason is high pressure shifting east while a strong ridge over the Southeast sends warmer, moisture-rich air northward. A frontal zone sitting to our north will occasionally send disturbances our way, which most likely will happen in the afternoon at the peak heat of the day.
A small shower or thunderstorm chance develops Wednesday night before Thursday turns mostly sunny and remains hot, with highs in the low to mid 90s. Another small chance of storms arrives Thursday night. By Friday, the ridge begins weakening and temperatures back off somewhat, with mostly sunny skies and highs in the upper 80s.
Saturday looks mostly sunny and warmer again, reaching around 90. The forecast becomes less certain heading deeper into the weekend as the ridge breaks down. Sunday brings a better chance for showers with partly sunny skies and highs in the upper 80s.
