Map of the Southern Water Resources Outlook Region

August 26, 2014 - Rainfall in August has been just about average, plus or minus an inch or so, for most of the southern portion of the MARFC service area. Much of central Maryland, northern Virginia, and even the central Delmarva Peninsula are running 1 1/2 to 3 1/2 inches above normal rainfall. Temperatures have been quite cool running 1 to 4 degrees below normal so far. Over the past 90 days, most areas have had near average rainfall plus or minus 1 to 2 inches. Parts of central and western Virginia are 3 to over 4 1/2 inches below normal. On the wetter side of things, parts of central Maryland and northern Virginia are 3 to over 6 inches above normal.

Current (August 26) streamflow data from the U.S. Geological Survey shows that streamflows are normal to above normal. Groundwater levels are near or above normal.

The weather outlook through the first week or so of September calls for below normal rainfall for the next week or so but then above normal rainfall. Temperatures are expected to be near or above normal. The NWS Climate Prediction Center's 30-day outlook for September calls for near normal rainfall and temperatures. The 90 day outlook for September through November calls for near average precipitation and above average temperatures.

Hurricane season is underway and tropical weather systems can bring flooding rains to the Mid-Atlantic Region. For now, no tropical system is threatening the Mid-Atlantic Region.

The outlook for water resources and supplies is good for Maryland, the eastern panhandle of West Virginia, Delaware, and much of Virginia. The outlook is fair for central and western Virginia due to an extended period of dryness. However, recent rain has eased this dryness a bit. It is common in the summer for some areas to get quite a bit of rain while nearby areas get very little. But over the longer term of weeks and months, most areas have been receiving sufficient rain to maintain good water resources and supplies. The exception, as mentioned above, is in central and western Virginia. Region-wide, the expectation of near or above average rainfall should maintain or improve water resources and supplies over the next couple of weeks.
