January 15, 2019 January precipitation has been about average, plus or minus a half inch or so. Temperatures have been running 4 to 6 degrees above normal. Over the past 90 days, precipitation has been 2 to 4 inches above average in southern New York and the northern half of Pennsylvania. In the southern half of Pennsylvania and in New Jersey, amounts have been 4 to 8 inches above. For calendar year 2018, precipitation was mostly 15 to 30 inches above normal, a very wet year for the Mid-Atlantic.

Generally 1 to 3 (and scattered areas of 4) inches of snow is on the ground in southern New York, southern Pennsylvania, and southern New Jersey. The water equivalent of this snow (or the water in the snowpack that will be released when the snow melts) is around one half inch or less.

Current (January 15) data from the U.S. Geological Survey shows that streamflows are near or above normal. Groundwater levels are much above normal.

The weather outlook into late January calls for above or much above average precipitation and below normal temperatures. This would suggest quite a bit of snow and/or ice. The NWS Climate Prediction Center's 30 day outlook for January 2019 as well as the 90 day outlook for January 2019 through March 2019 calls for near average precipitation and temperatures.

The outlook for water resources and supplies is very good or even excessive in spots with little change expected in the next week or two.
