WINTER STORM WATCH in effect for Franklin, Perry, Dauphin, Schuylkill, Lebanon and Cumberland Counties Wednesday night into Thursday.Warning

OVERVIEW:  Heavy snow will be possible Wednesday night into Thursday.  A strong storm will move up the east coast through the day Wednesday and continue towards the northeast Thursday. The storm track and northwestern extent of heavy snow is still somewhat uncertain.  Latest model data indicates the heaviest snow looks to set up across York, Adams and Lancaster Counties.  Areas north of the PA Turnpike in Franklin and Cumberland County, and north of I-81 in Dauphin and Lebanon County could pick up 4 to 6” of snow, however, south of the PA Turnpike in Franklin and Cumberland County and south of I-81 in Dauphin and Lebanon County, including the city of Harrisburg on south and east of there to the MD/PA border, may see anywhere from 6 to 10” with isolated higher amounts near a foot. Some of the latest model runs are showing sleet could mix in briefly which would also cut snow amounts down a bit.  We are sticking to our totals for now but will adjust if we feel the need to do so.
Snow 1

Snow develops anytime after 10pm Wednesday and continues through the day Thursday.  Some indications from the models show the snow lingering into early evening as moisture wraps around the departing storm.  Snow will be heavy at times during the morning commute.  Several inches will have accumulated by morning making traveling very difficult with snow covered roads.

TONIGHT:  Mainly clear skies right now will allow temperatures to drop fast.  Lows expected to dip anywhere from 3 below to 2 above zero.  The record at the Harrisburg International Airport is 0 set in 1979.  We’ll come close.  The forecast low is 1.
