December 22, 2012 - December, to date, has been quite wet with most areas running an inch or two above normal precipitation in south-central New York, Pennsylvania and New Jersey. Only areas in southern Pennsylvania are running close to normal. Over the past 90 days, precipitation has been near normal in most locations. However, precipitation in Adams and York counties in southern Pennsylvania and Cape May county New Jersey is 4 to 7 inches above normal. Year to date precipitation for 2012 has been fairly typical overall. The wettest area has been in south-central Pennsylvania with amounts 4 to 7 inches above normal. The driest areas have been in much of northwest New Jersey along with the Philadelphia area and adjoining sections of New Jersey. In these areas, precipitation has been 6 to 10 inches below average.

Current (December 22) streamflow data from the U.S. Geological Survey shows that streamflows are much above normal, though closer to normal in southern New Jersey. Groundwater levels have rebounded thanks to recent precipitation and are mostly near or above normal.

As we approach the end of December, snow has begun to cover portions of the MARFC service area, mainly in south-central New York and the central portion of Pennsylvania. Here, up to a few inches are on the ground, but is (for now) hydrologically insignificant. There are indications that the amount of snow may increase significantly in the upcoming days and possibly weeks.

The weather outlook into early January calls for above normal precipitation along with below average temperatures. This time of year, this is likely to mean snow over many (though not necessarily all) parts of the region. The Climate Prediction Center's 30 day outlook for January, 2013 as well as the 90 day outlook for January, 2013 through March, 2013 calls for near average precipitation and temperatures.

The outlook for water resources into early 2013 looks very good. Recent above normal precipitation has delivered significant amounts of water to all of south-central New York, Pennsylvania, and New Jersey. Dormant vegetation, low sun angle, and a likely continuation of above average precipitation should ensure that water resources and supplies will remain abundant for the next couple of months.

In summary, the northern portion of the MARFC service area has abundant water resources and water supplies. These water resources are likely to remain stable or increase in the upcoming weeks. With above normal precipitation expected in the short term and then generally near normal precipitation expected in the longer term, water resources should remain abundant and no water shortages are expected for the next couple of months.
