Winter Storm, Warren

When: January 2, 11:00 PM EST
Where: Warren forecast zone
Reported by: EMERGENCY MANAGER
Coordinates: 41.815, -79.274 (the zone’s center; the record gives no point)

Deep low pressure moved northeast across the upper midwest bringing large amounts of moisture into Pennsylvania east of the system. Very cold air trapped over the state permitted the precipitation to fall as light snow through the afternoon and evening of the 2nd before changing to sleet and freezing rain overnight. Heaviest snows fell across the Laurel Highlands of Somerset County, with Mt. Davis and Somerset both reporting 8 inches. Snowfall accumulations varied across the central mountains from about 1 to 4 inches. Water equivalent of the melted precipitation ranged from a half inch to over 2 inches. Fortunately, the heaviest precipitation fell as sleet, and most of the heaviest precipitation including freezing rain fell late at night. Because of the timing of the worst weather, traffic accidents were limited. There were a few power outages reported from the combination of ice and strong winds early Sunday morning. Some rural areas closed schools Monday because of icy roads.
