CWS Forecast: Ridge and Valley Region 

Cool temperatures will begin to moderate across the Commonwealth on Tuesday and especially Wednesday before cooler air again filters back into the area behind a departing trough of low pressure later in the day Thursday. Scattered showers can be expected on Thursday across much of the state as this trough moves through. As the cooler air filters in on Friday, expect those scattered rain showers to transition to scattered snow showers. Saturday looks to bring the return of seasonably cool temperatures to much of the Commonwealth.
