May 13, 2013 - The past week was quite wet with 2 to over 6 inches
of rain for most of the southern portion of the MARFC service area.
The exception was the central and lower Delmarva Peninsula and
southeast Virginia where 1/2 to 1 1/2 inches of rain fell. As a
result, most of this area is above or much above normal rainfall for
May except for the same areas just mentioned where rain has been about
normal plus or minus an inch or so. Precipitation over the past 90
days has been near normal plus or minus an inch or two over much of
the area with a few localized wetter areas in Virginia. Year to
date precipitation is mostly around normal plus or minus an inch or
two except for central and western Virginia. Here, precipitation has
been 2 to 6 inches above normal.
Current (May 13) streamflow data from the U.S. Geological Survey
shows that streamflows are mostly above to much above normal.
Groundwater levels are generally near normal.
The weather outlook through the next couple of weeks calls for
around or somewhat above normal rainfall. Temperatures are expected
to average out to about normal for the period, though both above and
below normal days are likely. The Climate Prediction Center's 30 day
outlook for May calls for near normal precipitation and temperatures.
The 90 day outlook for May through July calls for near average
precipitation and above normal temperatures.
The outlook for water resources has improved to good or very good
in the south and good in the north. Significant recent rainfall has
led to this improvement and has significantly reduced the long term
dryness in Maryland, the eastern panhandle of West Virginia, and
northern Virginia. Should rainfall dip to below normal, water
resources may become increasingly stressed in the upcoming weeks and
months. This does not, for now, appear to be the case.
In summary, the southern portion of the MARFC service area has
sufficient (even abundant) water resources and water supplies. These
water resources are likely to maintain current levels or begin their
typical long term decrease in the upcoming weeks but remain sufficient
with no water shortages expected in the next several weeks.
