Water Resources Outlook - Southern MARFC Area

Map of the Southern Water Resources Outlook Region

January 22, 2015 January has been dry in western Maryland, the eastern panhandle of West Virginia, as well as central and western Virginia where precipitation amounts have been about an inch below normal. For Delaware, the rest of Maryland, and eastern Virginia, precipitation has been normal to an inch and a half above. Temperatures have been averaging normal to a degree or two below. Over the past 90 days, precipitation in western Maryland, the eastern panhandle of West Virginia, as well as central and western Virginia has been 2 to 3 ½ inches below average. The remainder of the area (Delaware, the rest of Maryland, and eastern Virginia) has been closer to average.

For calendar year 2014, precipitation for much of far western Maryland, the eastern panhandle of West Virginia, and west-central Virginia was 6 to as much as 13 inches below normal. On the other hand, northeast and central Maryland as well as northern Virginia were wet running 6 to 11 inches above normal. Temperatures for 2014 were near normal in Delaware but below normal in Maryland, West Virginia, and Virginia.

Snow is still fairly minimal with depths of 1 to as much as 5 inches reported in much of Maryland, the eastern panhandle of West Virginia, Delaware, and northern-most Virginia. The water equivalent in this snow, or the amount of water that will be released when it melts, is under ½ inch. This amount of snow will have minimal or no hydrologic significance.

Current (January 22) streamflow data from the U.S. Geological Survey shows that streamflows are near or below normal. Groundwater levels are averaging near normal.

The weather outlook into early February calls for near or above average precipitation with the above average most likely to be along the coast. Temperatures are expected to be below or even much below normal. The NWS Climate Prediction Center's 30 day outlook for February as well as the 90 day outlook for February through April calls for near average precipitation and temperatures.

The outlook for water resources and water supplies is good for the southern portion of the MARFC service area. Sufficient precipitation coupled with the time of year has offset longer term dry weather. However, longer term precipitation deficiencies are becoming evident for much of western Maryland, the eastern panhandle of West Virginia, and Virginia. This area will be monitored in upcoming weeks should precipitation remain low.
