snow

Following a mild six days of December, when a number of locations approached or exceeded the 50° mark for highs, the bottom fell out of the thermometer. From the 7th through the 18th most of the northern half of the state failed to reach 40°, while southern locations only saw milder highs on the 14th, early on the 15th, and on the 17th. This includes the first sub-zero observation of the winter, when -1° was reached at Walpack (Sussex County) on the 17th and again on the 18th.
