September 16, 2017 September rainfall to date has been about normal plus or minus an inch or two. Temperatures have been cool averaging 2 to 5 degrees below normal. Over the past 90 days, rainfall has been about average or up to 2 or 3 inches above for most areas. Parts of southeast Pennsylvania along with southern New Jersey are running 4 to 10 inches above.

Current (September 16) data from the U.S. Geological Survey shows that streamflows and groundwater levels are both normal or above normal.

The weather outlook through the rest of September calls for below or much below average rainfall, though amounts could increase late in the period. Temperatures are expected to be above or much above average. The NWS Climate Prediction Center's 30 day outlook for September calls for above average rainfall and below average temperatures. The 90 day outlook for September through November calls for near average precipitation and above average temperatures.

The outlook for water resources and supplies is good or very good for southern New York, Pennsylvania, and New Jersey. Little change is expected in the near term. For now, a dry weather pattern has settled in, but it is offset by a weakening sun and lower water usage. This will, however, be watched for the longer term.
