Low pressure moved west to east along a stationary boundary draped across far northern Virginia and Maryland. Thunderstorms associated with this low pressure produced very high rainfall rates with the aide of a moisture laden atmosphere. Flash flooding and other nuisance flooding was reported across northern Fairfax County during the morning from rainfall amounts of 2 to 4 inches in less than 3 hours.
