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 temperatures.

Hurricane season has begun and tropical weather systems can bring flooding rains to the Mid-Atlantic Region. For now, the tropics are quiet.

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.
