May 19, 2014 - So far in May, much of Maryland, Virginia, and the eastern panhandle of West Virginia have had 1 to 3 inches of above average rainfall. The northern parts of the Delmarva Peninsula and even parts of southeast Virginia are running 1/2 to 1 inch below normal rainfall. Temperatures have been very warm running 3 to 6 degrees above normal to date in May. Over the past 90 days, northeast and central Maryland, as well as northern and central Virginia are running 3 to 7 inches above normal for precipitation. Meanwhile, far western Maryland and much of the adjacent eastern panhandle of West Virginia are 1 1/2 to 2 1/2 inches below average. Elsewhere, about average amounts of precipitation have fallen.

Current (May 19) streamflow data from the U.S. Geological Survey shows that streamflows are much above normal. Groundwater levels are above or much above normal.

The weather outlook for the rest of May calls for near or below normal rainfall. Temperatures are expected to be near or above normal. The NWS Climate Prediction Center's 30-day outlook for June calls for near or above normal rainfall and near normal temperatures. The 90 day outlook for June through August calls for near average precipitation and near or above average temperatures.

The outlook for water resources and supplies has improved to "good" for far western Maryland and adjacent portions of the West Virginia panhandle now that a significant storm brought much needed rain to this region. Long term dryness continues, but has eased for the time being. The far western Virginia counties are also within the "good" region. Elsewhere in Maryland, Delaware, and Virginia, very good water resources and supplies exist. The expectation of near or above average rainfall should ensure that water resources and supplies remain abundant for at least several more weeks in this area.
