Another blast of arctic air is heading our way. Temperatures slowly dropped through Monday afternoon, bringing much colder air for the overnight hours. Tuesday and Wednesday highs will only make it to the upper teens with subzero wind chills expected and snow showers are possible again on Tuesday afternoon and night. Meanwhile, the National Weather Service has issued a Cold Weather Advisory for the ridges of Westmoreland, Indiana and Fayette counties along with eastern Preston and Garrett counties in Maryland from 1 a.m. Tuesday through 10 a.m. Wednesday, where wind chills could get as low as -11 degrees. Snow showers will also be around at times starting Tuesday afternoon from lake effect snow. On and off snow showers are possible through Thursday. The big headline is the cold stretch that will continue through midweek, Wednesday morning wind chills will be back below zero. Make sure to limit time outdoors, wear warm layers if you are heading out, and keep pets inside.
