June 8, 2013 - June is off to a wet start for many, but not everyone. In New Jersey and southeast Pennsylvania, 3 to 6 inches of rain has already fallen. Meanwhile, in central and northeast Pennsylvania, only about 1/2 inch has fallen. Elsewhere, it's been an inch or two. Precipitation over the past 90 days has been average to 2 inches above average in New Jersey and southeast Pennsylvania, mainly due to recent rainfall. The rest of Pennsylvania is 2 to 3 1/2 inches below average while south-central New York is near average.

Current (June 8) streamflow data from the U.S. Geological Survey shows that streamflows are above or much above normal in south-central New York, southeast Pennsylvania, and New Jersey, mainly due to recent rainfall. Flows are near normal in the rest of Pennsylvania. Groundwater levels are mostly near or above normal for early June.

The weather outlook for the next couple of weeks calls for near or above normal rainfall along with near average temperatures. The Climate Prediction Center's 30 day outlook for June calls for near average precipitation and temperatures. The 90 day summer outlook for June through August calls for near average precipitation and above average temperatures.

Hurricane season has begun and rains from a tropical system can bring significant rainfall to the Mid-Atlantic Region, as we have just seen. If or when this occurs, water resources and supplies can change quite quickly.

The outlook for water resources is fair to good in south-central New York and most of Pennsylvania. The outlook is good for southeast Pennsylvania and New Jersey. As is typical for this time of year, rainfall can be significant in one area while largely missing another. So, while there are wet and dry areas right now, this can change fairly quickly based on rainfall, and this has just happened. There are currently no strong signals that extended dry weather will settle in to the region any time soon. At the same time, there is also no guarantee that summertime showers and thunderstorms will reach every location. So, while good water resources and supplies are expected, it is also possible that some spots could see a relative lack of rain leaving the possibility of only "fair" conditions.

In summary, the northern portion of the MARFC service area has sufficient water resources and water supplies. These water resources and supplies are likely to maintain current levels or begin their typical slow long term summer decrease in the coming weeks, but remain sufficient, with no water shortages expected in the next several weeks. Near or above normal rainfall in the short term is expected to maintain the current status of water resources and supplies.

End.
