The period from this Thursday afternoon through Thursday morning of next week (19th) is likely to see intervals of the coldest air of the season, with several mornings of subzero cold over the greater than 4 inch snow pack along and north of Interstate 78 in PA/NJ. The coldest morning should be Monday February 16. For some of the urban areas this might be coldest February outbreak since February 1996.

Wind chill of 10 to 25 below zero (25 below reserved mostly for the Poconos), can occur on 2 or 3 mornings, including both Sunday and Monday mornings.

People outdoors for extended periods of time need to be prepared for these harsh-very cold conditions. Check your heating fuel to ensure you have enough to last through this rather cold period ahead.

Snow will probably cause hazardous travel for the Thursday evening commute (12th) over Pennsylvania and the north two thirds of NJ. This will be associated with a quickly departing clipper storm redevelopment east of the Delmarva.

More extensive and possibly heavier amounts of snow are possible Saturday afternoon and night (14th) with the next clipper redevelopment east of NJ. This promises to be a larger and stronger storm. The proximity of its development to the coast will govern snowfall amounts. There is still uncertainty.

Strong winds in the wake of these developing storms may cause isolated power outages. Timing for these strong winds are early Thursday night and again Saturday night into Sunday. Gusts to 45 mph are possible.

Wintry precipitation is possible again next Tuesday or Wednesday the 17th-18th. For more information on this weather event visit the Mount Holly Weather Site at:
