Sunshine and lower humidity stick around before a rain chances return this weekendA beautiful stretch of late-July weather continues through Friday before widespread rain returns for the first weekend of August. A Cool and Comfortable Night AheadThe comfortable weather continues tonight as skies remain mostly clear and temperatures quickly cool after sunset. A disturbance is expected to move into the Ohio Valley Friday night into Saturday, bringing moisture and widespread rain back into the region. The system responsible for the weekend rain will be slow to move out, allowing lighter showers and possibly a few thunderstorms to linger into Sunday. Temperatures will also be held down by the additional clouds and rain, with weekend highs generally ranging from the upper 70s to mid-80s.
