However, the approach of fall can be sensed in occasional cooler breezes and sporadic thunderstorms that may offer brief respite from the summer heat.

Comparing August to July, a subtle shift towards milder temperatures becomes noticeable, especially towards the end of the month. The transition from the peak summer heat to the more temperate climate of September is gradual and often accompanied by increased rainfall.

Areas like the Allegheny Plateau might experience varied precipitation, contributing to the overall weather pattern in August. The state's topography, including features like the Chesapeake Bay and the Potomac River, continues to play a significant role in shaping the climate.
