July 15, 2013 - "Wet wet wet" best describes the weather over the past month or so. Through mid-July, 3 to over 6 inches of rain has fallen in Delaware, eastern Maryland, and Virginia. Lighter amounts of 1 1/2 to 3 1/2 inches have fallen in the rest of Maryland and the eastern panhandle of West Virginia. For the past 90 days, western Maryland, the eastern panhandle of West Virginia, and parts of northern Virginia have seen near normal rainfall, while areas further south and east have seen 3 to more than 11 inches above normal rainfall.

Current (July 15) streamflow data from the U.S. Geological Survey shows that streamflows are much above normal in Delaware, Virginia, and the eastern panhandle of West Virginia. In central Maryland, flows are about normal. Groundwater levels are generally near or above normal.

The weather outlook through late July calls for below normal rain and above normal temperatures early in the period. Then, near or above normal rainfall will return along with near normal temperatures. The NWS Climate Prediction Center's 30-day outlook for July shows equal chances of temperatures being below normal, normal, or above normal, while above average rainfall is expected. The 90-day outlook for July through September indicates essentially equal chances of both temperatures and precipitation being below normal, normal, or above normal.

Hurricane season is underway and rains from a tropical system can bring significant rainfall to the Mid-Atlantic Region. The tropics are currently quiet in the Atlantic Ocean and Gulf of Mexico.

The outlook for water resources across the southern half of the MARFC service area is very good. No areas of drought or water supply shortages currently exist, and none are expected to form during the next few weeks. At this time a sustained dry weather pattern is not indicated and, in fact, a normal or wet weather appears to be likely.
