An anomalously moist airmass with tropical moisture resided over much of Maryland on July 16th. This comes after several days of showers and thunderstorms, which left some areas with suppressed flash flood guidance. Slow moving thunderstorms developed on remnant boundaries and terrain circulations before propagating eastward. These storms produced localized rainfall amounts of two to five inches.
