A storm system will move through the area starting late on Tuesday afternoon, with the heaviest snow falling over night. I expect most in Allegheny County will awaken to 3-6″ of snow, with lighter periodic snow showers continuing throughout the day on Wednesday. Showers will continue overnight Wednesday and linger throughout the day Thursday. Total from Tuesday through Thursday evening should fall in the 4-8″ range.
In addition to the early cold, Lake Effect snow will continue to spread periodic showers throughout the remainder of November. I am also watching for the potential for another snow storm during the first week in December.
