May 6, 2014 - April ended with a big storm for much of Maryland and Virginia leaving a large swath of above normal rainfall in the southern portions of the MARFC service area. Breaking April rainfall down into regions, most of the Delmarva Peninsula saw normal to an inch or so above normal rainfall. The northern Delmarva Peninsula was 2 to 4 inches above normal. Northeast and central Maryland along with much of northern and central Virginia had 2 to 6 1/2 inches above normal rainfall. (And further west) western Maryland, the eastern panhandle of West Virginia and western Virginia were near normal plus or minus an inch. Temperature-wise, after 3 months of below or much below average temperatures, April ended nearly normal (plus or minus up to a degree or so) for most of the southern portion of the MARFC service area. Over the past 90 days, northern Delaware, northeast and central Maryland, as well as northern and central Virginia are running 3 to 7 1/2 inches above normal for precipitation. Meanwhile, far western Maryland and much of the eastern panhandle of West Virginia are 1 1/2 to 2 1/2 inches below average. If your area wasn't mentioned, then about average amounts of precipitation have fallen.

Current (May 6) streamflow data from the U.S. Geological Survey shows that streamflows are near normal in the west, above or much above normal elsewhere. Groundwater levels are above or much above normal.

The weather outlook for the next couple of weeks calls for near or below normal rainfall in the near term but then above average rainfall is likely to return. Temperatures are expected to be near or above normal. The NWS Climate Prediction Center's 30-day outlook for May calls for near normal precipitation and temperatures. The 90 day outlook for May through July calls for near average precipitation along with above average temperatures.

The outlook for water resources and supplies has been downgraded to "fair" for far western Maryland and adjacent portions of the West Virginia panhandle. Significant precipitation (including the most recent storm) has been missing this area meaning long term dryness continues. As we enter the warm season, this will be an area of concern should long term dry weather continue. Recently, the far western Virginia counties (to a lesser degree) have also been missing out on the heaviest precipitation. This is the "good" region and will be monitored closely for rainfall in the upcoming weeks. 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.

End.
