DAYS 1-5 (DECEMBER 16-20)
Low pressure brings wet weather into the region during the course of the day today although a few pockets of sleet are possible at the onset of the rain, then colder air arriving from above and from the northwest will attempt to change rain to sleet/snow, most successfully in higher elevations west and north later this evening and moving southeastward thereafter but as precipitation tapers off. Leaving yesterday’s numbers the same for now. Blustery, colder air in control much of Monday and Tuesday as it dries out. Moderating temperatures at midweek and may get wet by the end of December 20 with the next low pressure system from the west.
