FIRST...MAJOR WINTER STORM OF THE SEASON SO FAR ACROSS CENTRAL PENN.
WARM CONVEYOR BELT...AND THE NOSE OF A SWRLY 55 KT 850 MB JET WILL
CONTINUE TO SUPPLY ABUNDANT MOISTURE AND LIFT FOR STEADY PRECIP
THROUGH THE MID MORNING HOURS TODAY. TEMPS ALOFT HAVE JUMPED SEVERAL
DEG LEADING TO A CHANGEOVER TO FREEZING RAIN FOR ALL AREAS SOUTH OF
INTERSTATE 80. RADAR BRIGHT BAND AND SFC OBS SHOW A MIXED BAG OF
PRECIP BETWEEN I-80 AND STATE ROUTE 6...WITH ALL SNOW NEAR THE NEW
YORK BORDER.
HEAVY ICE ACCUMULATION OF AROUND 0.5 OCCUR ACROSS THE MUCH OF THE
CENTRAL RIDGE/VALLEY REGION...AND MIDDLE SUSQ VALLEY WITH SLIGHTLY
LESSER AMOUNTS ACROSS THE LAUREL HIGHLANDS WHERE PRECIP RATES HAVE
BEEN LOWER.
NEAR SFC TEMPS LOOK ON TRACK TO WARM TO JUST ABOVE FREEZING ACROSS

UPPER BYLR TEMPS BECOME SUFFICIENTLY COLD FOR SCATTERED LAKE EFFECT
SNOW SHOWERS ACROSS THE NRN AND WESTERN MTNS TONIGHT...BUT A LOW
SUBSIDENCE INVERSION AND A FAIR AMOUNT OF SHEAR LATER TONIGHT WILL

850 MB TEMPS MODERATE QUICKLY ON FRIDAY WITH PARTLY SUNNY SKIES
(MSTLY SUNNY FOR SEVERAL HOURS ACROSS THE SE) FOLLOWED BY THICKENING
HIGH CLOUDS SPREADING IN FROM THE WEST LATE IN THE DAY.
BIG MODEL DIFFERENCES (ETA/GFS) FOR THE NEXT SHORT WAVE/SFC LOW
APPROACHING FROM THE SW FRIDAY NIGHT. GFS SUGGESTS A MUCH WETTER AND
SOMEWHAT COLDER ATMOS THAN THE ETA...WHICH KEEPS THE BULK OF ITS QPF
NEAR AND JUST SOUTH OF THE MASON/DIXON LINE. LEANED TOWARD A BLEND
OF BOTH (SOLELY FOLLOWING THE GFS WOULD LEAD TO MUCH HIGHER POPS

PARTS OF CENTRAL PENN LATE FRIDAY NIGHT/SAT MORNING.
