A STORM SYSTEM WILL TRACK ACROSS THE OHIO RIVER VALLEY...TO JUST
SOUTH OF PENNSYLVANIA LATE SATURDAY. ANOTHER STORM WILL LIKELY
PASS NORTH OF PENNSYLVANIA MONDAY NIGHT OR TUESDAY...FOLLOWED BY
SOME OF THE COLDEST TEMPERATURES SO FAR THIS WINTER LATER NEXT
WEEK.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
LOCALLY HVY LAKE EFFECT SNOW HAS SHIFTED JUST TO THE NORTH OF THE
NEW YORK BORDER WITH MCKEAN AND WARREN COUNTIES...AFTER DUMPING
ANYWHERE FROM 3 TO 11 INCHES OF SNOW THERE. THE 12Z WRKARWS WELL-
DEFINED BAND OF 925-850 HPA THETA-E CONVERGENCE SUPPORTS THE AXIS
OF LES STAYING MAINLY TO THE NORTH OF THE NEW YORK STATE

ELSEWHERE...WEAK ISENTROPIC LIFT ALONG THE 275-280K THETA SURFACE
WILL MAINTAIN BKN STRATO CU AND OCCASIONAL FLURRIES ACROSS MUCH OF
CENTRAL AND WRN PENN...PRIOR TO A THICKENING SHIELD OF CIRRUS AND
ALTOSTRATUS ADVECTING IN FROM THE WEST LATE TODAY/THIS EVENING.

DOWNSLOPING FLOW WILL YIELD PTSUNNY SKIES ACROSS THE SUSQ
VALLEY...ALLOWING READINGS TO REACH TO THE M30S FOR AFTERNOON HIGHS.
ACROSS THE ALLEGHENIES...PERSISTENT STRATOCU LIKELY TO HOLD TEMPS
DOWN WITH MAX READINGS ONLY IN THE M20S.

WINTER STORM WATCHES WILL LIKELY BE UPGRADED TO WARNINGS ACROSS
MUCH OF CENTRAL AND NRN PENN WITH THE LATE AFTERNOON GRID/ZFP ISSUANCE.
LEANING MORE TWD ADVISORY AMOUNTS OF SNOW WITH SOME SLEET ACROSS
THE SOUTHERN TIER COUNTIES.

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
OPEN WAVE AT H5 TRAVERSING THE MIDWEST GAINS STRENGTH TONIGHT...WITH
STRONG SOUTHERN STREAM JET DYNAMICS A BIG INFLUENCE IN DRAWING
GULF MOISTURE NORTHEASTWARD INTO THE DEVELOPING SURFACE LOW ACROSS
THE OHIO VALLEY. ALL MODEL AND ENSEMBLE SOLUTIONS CONTINUE TO SHOW
A FAVORABLE SFC LOW TRACK ALONG/SOUTH OF THE MASON DIXON FOR
MODERATE TO HEAVY SNOWFALL ACROSS CENTRAL PA ON SATURDAY. LATEST
SREF DATA INDICATES SNOW WILL SPREAD EASTWRD ALONG BAROCLINIC ZONE
INTO CENTRAL PA BY LATE THIS EVENING...WITH HIGHEST /CATEGORICAL/
POPS TONIGHT INDICATED FOR THE I-80 CORRIDOR.

CURRENT GRIDDED SNOWFALL AMOUNTS ARE AT THE TOP END OF THE SREF
PLUME DATA. THESE AMOUNTS FELL OUT OF A MEAN BLEND OF HPC AND ALL
AVAILABLE MODEL AND ENSEMBLE DATA. THIS BLEND WAS USED IN ATTEMPT
TO MITIGATE UNCERTAINTY. THERMAL PROFILES FROM THE NAM/GFS/SREF
SUGGEST SOME FREEZING RAIN OR EVEN RAIN WILL BE PSBL SATURDAY ACROSS
THE SRN TIER DEPENDING ON EXACT STORM TRACK...THIS SHOULD TRIM
SNOWFALL TOTALS TO BETWEEN 2 AND 4 INCHES ALONG THE MASON DIXON LINE.
CLOUD LAYER TEMPS ARND -6C (WITH THE MAX UVVEL FOR MUCH OF THE
EVENT BELOW THE FAVORABLE DENDRITIC SNOW GROWTH THERMAL RIBBON OF
-12 TO -18C ALL THE WAY UP AT 10-15 KFT AGL) INDICATES THAT
RIMING/AGGREGATION WILL HOLD SNOW RATIOS CLOSE TO 10/1 FOR THIS
EVENT (SLIGHTLY HIGHER AROUND 12:1 ACROSS THE NRN PENN MTNS).

AN EXAMINATION OF THE LATEST ENS DATA CONTINUES TO POINT TOWARD
THE BEST CHC OF WARNING TYPE SNOWFALL ALONG AND JUST TO THE NORTH
OF THE I-80 CORRIDOR WITH WANING CONFIDENCE NEAR THE NEW YORK
BORDER AND ACROSS THE SOUTH. THAT SAID...A 6-8 INCH SNOWFALL
REMAINS WITHIN THE ENVELOPE OF SOLUTIONS THROUGHOUT THE CWA...AS
EVIDENCED BY SEVERAL 03Z SREF PLUME MEMBERS WITH QPF NR 1 INCH AT
BOTH BFD AND MDT. 09Z SREF MEAN LIQ EQUIVALENT QPF HAS EDGED UP BY
5-10 HUNDREDTHS ACROSS MUCH OF CENTRAL PENN WITH SIMILAR AMOUNTS
ACROSS THE FAR NORTH. A LATE AFTERNOON MIX WITH SLEET OR RAIN IS
STILL IN THE CARDS FOR THE FAR SOUTH BASED ON THIS 09Z RUN AND 12Z
OPERATIONAL NAM GUIDANCE.

AS THE LOW SLIDES NEWD OFF THE MID ATLC COAST...SNOW SHOULD TAPER
OFF SAT NIGHT...WITH SOME LAKE EFFECT/OROGRAPHIC SNOW SHOWERS
DEVELOPING ACROSS THE NW MTNS AND WESTERN HIGHLANDS.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
LK EFFECT REGIME SHOULD DIMINISH ON SUNDAY AS HIGH PRES NOSES IN
AHEAD OF THE NEXT CLIPPER ENTERING THE GRT LKS REGION BY MON. 00Z
NAEFS/ECMWF/GEFS SHOW THIS SYS PASSING NORTH OF PA MON NITE/EARLY
TUESDAY. HOWEVER...A LIGHT SNOWFALL APPEARS LIKELY TO ACCOMPANY
THIS SYS...ESPECIALLY OVR THE NW MTNS. HIGH CONFIDENCE CONTINUES
IN THE STRONG PNA LONGWAVE PATTERN...WITH ARCTIC AIR TO DOMINATE
THE ERN CONUS FOR THE SECOND HALF OF THE PD.
