May 19, 2014 - So far, May rainfall has ranged from below normal in New Jersey to above normal in southern New York and central Pennsylvania. In New Jersey, rainfall has been generally near normal to about an inch below normal. Much of eastern Pennsylvania has seen about average rainfall. But for the rest of Pennsylvania and southern New York, rain has been an inch or two above normal. It has been warm so far with temperatures running 2 to nearly 4 degrees above normal. Over the past 90 days, most of the northern portion of the MARFC area has had about average precipitation plus or minus an inch or two. Southeast Pennsylvania has been the wettest region running 2 to 4 inches above average for precipitation.

Current (May 19) streamflow data from the U.S. Geological Survey shows that streamflows are running much above normal. Groundwater levels are, on average, above or much above normal.

The weather outlook for the rest of May calls for near or above average rainfall. Temperatures are expected to begin the period below normal but, for most of this period, be above normal. The NWS Climate Prediction Center's 30-day outlook for June calls for near average rainfall along with near or below normal temperatures. The 90 day outlook for June through August calls for near average rainfall and near or above average temperatures.

The outlook for water resources is good across southern New York and much Pennsylvania and is very good across southeast Pennsylvania and all of New Jersey. Recent above normal rainfall has largely eliminated any long term dryness but will have to continue in New York and Pennsylvania for this outlook to become "very good." Additional rainfall (likely to be above normal), suggests that further improvement is possible. Precipitation in New Jersey and southeast Pennsylvania remains sufficiently above normal and likely ensures that very good water resources and supplies will continue well into summer.
