October 13, 2013 - A major storm brought drenching rains to the southern halves of Pennsylvania and New Jersey. 2 to 9 inches of rain have been common so far in October for these areas with a few spots getting over 10 inches of rain. Further north in Pennsylvania and in south-central New York, an inch or two has fallen so far this month which is normal or a bit above. The northern half of New Jersey has missed most of the rain where only 1/2 to an inch has fallen, leaving this area below normal. As for rainfall over the past 90 days, most of central and northeast Pennsylvania along with northern New Jersey are 2 to 5 inches below average rainfall. Elsewhere, rain has been average to as much as 5 (even 6 or 7) inches above average. Recent heavy rainfall has wiped out or significantly decreased recent precipitation deficits.

Current (October 13) streamflow data from the U.S. Geological Survey shows that streamflows are running from near to above normal except for the southern half of Pennsylvania and southern New Jersey. Here, flows are much above normal. Groundwater levels are mostly around normal levels with some scattered readings both above and below normal.

The weather outlook through late October calls for around normal precipitation with temperatures about typical for this time of year. The NWS Climate Prediction Center's 30-day outlook for October calls for near average precipitation with temperatures above or even much above normal. The 90 day outlook for October through December calls for near average precipitation and temperatures.

The outlook for water resources is very good across much of the northern half of the MARFC service area. In areas of the northern half of Pennsylvania and northern New Jersey, the outlook is good. Recent heavy rainfall has considerably eased the concern for dryness. Further, as we continue to move deeper into autumn and the strength of the sun continues to lessen, dryness concerns lessen. As a whole, water resources and supplies are sufficient or abundant.

End.
