August 10, 2013 - Rainfall in July varied quite a bit. The wettest areas were in south-central New York north of Binghamton, southeast Pennsylvania, and much of western New Jersey. In these areas, rainfall was 1 to 4 inches above normal. On the other hand, portions of central and northeast Pennsylvania along with northeast New Jersey were an inch or two below normal. July temperatures were 2 to 4 degrees above normal. The first week or so of August has been wet for south-central New York, much of eastern and southern Pennsylvania, and northern New Jersey where 1 1/2 to 4 inches of rain has already fallen. Elsewhere, near normal rain has fallen. Rainfall over the past 90 days has been about average (plus or minus an inch or two) for parts of south-central New York and most of Pennsylvania. But, New York around, north, and east of Binghamton, eastern Pennsylvania and New Jersey have seen 4 to more than 10 inches more rainfall than what is typical. This sounds confusing, but indicates the scattered nature of rainfall for this time of year.

Current (August 10) streamflow data from the U.S. Geological Survey shows that streamflows range from near to much above normal in the northern half of the MARFC service area. The wetter areas are, as expected, where the heaviest rain has been falling. Groundwater levels are near or above normal.

The weather outlook for the next couple of weeks calls for generally near normal rainfall. Temperatures are expected 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 indicates that rainfall should be near average and temperatures are expected to be near or possibly above normal.

Hurricane season is entering its' more active period and rains from a tropical system can bring significant rainfall to the Mid-Atlantic Region. The tropics are currently mostly quiet in the Atlantic Ocean and Gulf of Mexico. Rain from a tropical system is not expected in the near term.

The outlook for water resources is very good across the northern half of the MARFC service area. Though not all areas have been receiving the heaviest rains, when taken as an average, water resources and supplies are abundant. Long range weather outlooks are not indicative of a long spell of dry weather, though the rather lengthy period of above normal rainfall may be easing up.

End.
