July 21, 2014 - The scattered nature of summer-time rainfall has
been obvious so far in July with amounts ranging from as little as 1
1/2 inches to over 6 inches to date. The wettest areas have been in
the Catskill Region of New York, east-central Pennsylvania, and much
of New Jersey. The driest areas have been scattered in Pennsylvania.
But, summer-time thunderstorms and heavy rain can change this fairly
quickly. July temperatures have been fairly typical so far averaging
about normal plus or minus a degree or so. Over the past 90 days,
much of southern New York, the northeast quarter of Pennsylvania, and
far southern New Jersey have had near average rainfall. The Catskill
Region of New York as well as the remainder of Pennsylvania and New
Jersey is running 2 to 5 inches above average.
Current (July 21) streamflow data from the U.S. Geological Survey
shows that streamflows are running near to above normal. Groundwater
levels are near or above normal.
The weather outlook into early August calls for above average
rainfall. Temperatures are expected to be near normal early in the
outlook but then to be below normal. The NWS Climate Prediction
Center's 30-day outlook for August as well as the 90 day outlook for
August through October calls for near average rainfall and
Hurricane season has begun and tropical weather systems can bring
flooding rains to the Mid-Atlantic Region. For now, the tropics are
The outlook for water resources and water supplies is good or very
good across southern New York, Pennsylvania, and New Jersey. The only
area that had been experiencing long term dryness was far southern New
Jersey, but short term rainfall has eased this dryness. Elsewhere,
though rainfall has been hit or miss at times for short periods, the
longer term of weeks and months has brought sufficient rain to just
about all areas to maintain good or very good water resources and
supplies. Further, additional rainfall suggests that good or very
good conditions will continue for the next several weeks.
