September 11, 2014 - Rainfall in August was just about average,
plus or minus an inch or so, for most of the southern portion of the
MARFC service area. Parts of central Maryland, far western Maryland,
northern Virginia, and even the central Delmarva Peninsula were 2 to 4
inches above normal rainfall. Temperatures were quite cool running 1
to 3 1/2 degrees below normal. As for September, rainfall has been an
inch or less for most areas. The exception is the southern half of
the Delmarva Peninsula and southeast Virginia where 2 1/2 to over 8
inches has fallen to date. Temperatures have been warm running 3 to 5
1/2 degrees above normal. Over the past 90 days, many areas have had
near average rainfall plus or minus 1 to 2 inches. On the dry side,
parts of central and western Virginia are 3 to nearly 5 inches below
normal. On the wetter side of things, far western Maryland and
southeast Virginia are 3 to 6 inches above normal.
Current (September 11) streamflow data from the U.S. Geological
Survey shows that streamflows are normal, though some flows in far
western Virginia are below normal. Groundwater levels are near or
The weather outlook for the next couple of weeks calls for near
average rainfall and below average temperatures. The NWS Climate
Prediction Center's 30-day outlook for September along with the 90 day
outlook for September through November calls for near average
precipitation and above average temperatures.
We are at the peak of hurricane season, which has been fairly quiet
to date. Tropical weather systems can bring flooding rains to the
Mid-Atlantic Region. But 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. Region-wide, the expectation of near
average rainfall should maintain the current status of water resources
and supplies over the next couple of weeks.
