August 16, 2014 - Rainfall in August has been very heavy for some,
but very little for others. Much of central Maryland, eastern
Virginia, and the Delmarva Peninsula is running 1 1/2 to 3 1/2 inches
above normal rainfall. On the flip side, much of west-central
Virginia has only had about an inch of rain so far in August.
Temperatures have been quite cool running 1 to more than 5 degrees
below normal so far. Over the past 90 days, dating back to the middle
of May, most areas have had near average rainfall plus or minus 1 to 3
inches. Much of central and western Virginia is 3 to 6 inches below
Current (August 16) 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 most of the rest of August calls for
above normal rainfall. Temperatures are expected to be near or below
normal to start the period but then become near or above normal. The
NWS Climate Prediction Center's 30-day outlook for August calls for
near normal rainfall and temperatures. The 90 day outlook for August
through October calls for near average rainfall and near or above
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. 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 above average
rainfall should maintain or improve water resources and supplies over
the next couple of weeks. But, should this rain not materialize, then
conditions in central and western Virginia will likely deteriorate
