December 18, 2013 - December has been quite wet or white to date with 2 to over 3 1/2 inches of precipitation. This is much above normal. Much of this has been snow and/or ice, so these amounts represent the rain and water equivalent of the snow and ice that has fallen. Overall, long term dry conditions are dwindling. For the past 90 days, Delaware, much of Maryland, far eastern portions of the West Virginia panhandle, as well as northern and eastern Virginia are running near to over 3 inches above average. Elsewhere, precipitation has been 1 to 2 1/2 inches below average. Calendar year 2013 is winding down. To date, Delaware, most of Maryland east of the Chesapeake Bay, and much of central and southern Virginia is 5 to more than 10 inches above normal. A small dry area is Allegany County, MD and Mineral County, WV where amounts have been 5 to 7 inches below normal. Elsewhere, amounts are within a couple of inches of normal.

As for snow, 2 to 7 inches of snow covers the ground in northern and western Maryland, the eastern panhandle of West Virginia, and northernmost Virginia. Elsewhere in the southern portion of the MARFC service area, little or none is on the ground. The water equivalent in this snow, or the amount of water that will be released when the snow melts, is 1/2 to nearly 1 1/2 inches and, in the absence of a heavy rain event, is not considered to be hydrologically significant.

Current (December 18) streamflow data from the U.S. Geological Survey shows that streamflows are near or above normal. Groundwater levels are generally near or above normal.

The weather outlook through the end of the month and year calls for near or above average precipitation. Temperatures are expected to be mostly near or above normal. This outlook suggests that some portion of the snow will likely melt during this period. The NWS Climate Prediction Center's 30-day outlook for December as well as the 90 day outlook for December, 2013 through February, 2014 calls for near average precipitation and temperatures.

Recent storminess has essentially eliminated dry conditions and the weather outlook suggests that rain and melting snow will likely contribute further to water supplies and resources. The outlook for water resources and supplies is good or very good across all of the southern portion of the MARFC service area. Water resources and supplies are sufficient to abundant.

End.
