The dryness associated with record heat in the Mid Atlantic and Northeast has increased the extent of the minimal drought coverage in those areas. This week's U.S. Drought Monitor, released this morning, shows Maryland, Delaware, and New Jersey continuing with 100% in the Abnormally Dry (D0) category. Meanwhile, Virginia has increased from 80% to 85%. The extent of the dry area has expanded to the north, with the Northeast overall rising from 33% to 48%. The biggest increases are in Pennsylvania, rising from 56% to 91%, and New York (8% to 32%). Connecticut has also increased, from 67% to 79%. The Abnormally Dry area has crept northward into western Massachusetts; that state's coverage has increased from 0 to 25%.
In the Washington DC area, the mostly dry week has added to the accumulated deficit. The year-to-date precipitation totals and departures from average are:
Washington National: 9.22"/-24%
Washington Dulles: 9.51"/-24%
Baltimore (BWI): 10.86"/-18%
