WINTER STORM WARNING in effect Wednesday night into Thursday for York, Adams and Lancaster Counties.
WINTER STORM WATCH in effect for Franklin, Perry, Dauphin, Schuylkill, Lebanon and Cumberland Counties Wednesday night into Thursday.
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 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.
TOMORROW: Plenty of sunshine to start the day but clouds will be increasing from the south as the next storm moves in. Temperatures rebound only to the low to mid 20s which continues well below the average for this time of the year.
VALENTINES DAY: Looks like most of the day will be dry and quiet. Temperatures will be warmer and closer to average in the upper 30s. The next clipper system comes in Friday evening and may provide a few light snow showers late.
WEEKEND OUTLOOK: Temperatures will continue cold and below average with morning lows in the teens and 20s and highs around 30° There will be another quick moving system Saturday night into Sunday morning which may produce some light snow flurries or light snow showers.
EARLY NEXT WEEK: Looks like temperatures warm a bit with rain showers possible late Monday. Highs Tuesday could reach 42°!
