A weak system will drop across the area Saturday night bringing the chance of a few sprinkles. && .NEAR TERM /THROUGH TONIGHT/... Surface high pressure over the upper Great Lakes will slowly slide to the southeast into tonight. The middle Ohio Valley will remain under the influence of this high, with mostly clear skies and light winds the result. Low temperatures will dip into the 50s. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... The high will remain the primary driver of Ohio Valley weather Friday and Friday night.

Surface high pressure remains overhead on Saturday. Weak southwesterly flow develops during the day. Forecast highs are in the middle 80s under partly cloudy skies.
