Daily Potomac flow and demand update (Friday 07/30/2010)
Yesterday's storms resulted in accumulations of over a half inch of rain in certain localized areas of the basin near the Washington metropolitan area, causing flow at Little Falls to rise slightly. However, most upstream areas of the basin received little or no rain. There is a chance of thunderstorms this weekend, and the National Weather Service (NWS) quantitative precipitation forecasts (qpf) indicate that the majority of the basin may receive from 1/4 to 1 inch of rain over the next 48 hours.
