December 8, 2014 - November precipitation was quite light in
southern New York and most of Pennsylvania where only 1 1/2 to 2 1/2
inches fell. Southeast Pennsylvania and New Jersey were wetter with 3
to over 5 inches of precipitation. Temperatures for November averaged
2 to 4 degrees below normal. The first week of December has already
brought 1 to 2 inches of precipitation with more on the way. Over the
past 90 days, precipitation for southern New York, Pennsylvania, and
northwest New Jersey has been running 2 to 5 inches below average.
The rest of New Jersey and southeast Pennsylvania has been around
normal plus or minus an inch or two.
Current (December 8) streamflow data from the U.S. Geological
Survey shows that streamflows are running near or above normal.
Groundwater levels are below normal in much of the eastern half of
Pennsylvania and the Catskill Region of New York. Elsewhere,
groundwater levels are near normal.
The weather outlook through the next couple of weeks calls for
above normal precipitation early in the period but then below normal
precipitation. Temperatures are expected to begin the period around
average but then warm to above average levels. The NWS Climate
Prediction Center's 30 day outlook for December calls for near average
precipitation and above average temperatures. The NWS Climate
Prediction Center's 90 day outlook for December, 2014 through
February, 2015 calls for near average precipitation and temperatures.
The outlook for water resources and water supplies is "good" across
southern New York, Pennsylvania, and New Jersey. This is an
improvement in the Catskill Region of New York, parts of Pennsylvania,
and the northern half of New Jersey. Dry conditions have persisted
for much of the past few months interrupted by only brief wet periods.
However, recent above or even much above normal precipitation along
with the expectation of additional significant precipitation has led
to an improvement in the outlook. In fact, additional improvement is
likely as a result of the next significant storm system. With the
onset of winter, degradation in water resources and supplies is
unlikely and further improvement may occur quite quickly if wet
weather were to persist.
