Heavy downpours of July 10: flooding in Bloomingdale, D.C.

Doppler estimate rainfall totals. In some areas of D.C., these appear to be underestimates. (National Weather Service)
A weak area of low pressure passed over the D.C. area yesterday evening. As the atmosphere was flush with moisture, a localized, but intense band of thundershowers developed between central Fairfax county and north central Prince George’s county.

Torrential rain accompanied the slow-moving thundershowers (atmospheric steering currents were weak) - with some of the heaviest rain falling in the heart of the District of Columbia.
