Special Weather Statement issued November 21 at 7:41PM EST by NWS State College PA

A several hour period of wet snow is likely early Friday as surface low pressure strengthens off the New Jersey Coast and upper level low pressure with cooling temperatures aloft moves east across Pennsylvania. Snow accumulations will be light and generally less than one inch. However, with forecast low temperatures between 30 and 34 degrees, some untreated roads and bridges could develop a light coating of slush creating slick travel conditions. Plan for the possibility of variable travel conditions and allow a little extra time for travel, especially if your route takes you over some of the ridge tops.
