Prior to the weekend’s rain, the annual deficit rainfall deficit at DCA had passed 5” and drought conditions had creeped into the eastern suburbs. The year-to-date rain of 5.75” was just 0.2” above the lowest output on record since 1871. After Sunday, the rainfall deficit stands at an improved but still lacking 3.97”. In other words, we need water to keep coming and, fortunately, it’s in the forecast.

Dulles Airport received 0.96” and BWI 1.33”.
