What happened

The episode as NWS PHI wrote it up.

A protracted event of light snow, sleet and especially freezing rain caused traveling difficulties and accidents in Eastern Pennsylvania from the evening of the 8th through the overnight on the 9th. While precipitation amounts were not heavy and occurred intermittently, untreated roadways were treacherous. Ice accumulations averaged around one tenth of an inch and snow and sleet accumulations in the Lehigh Valley and Poconos averaged around one inch with lighter accumulations if any in the rest of Eastern Pennsylvania. Many schools on the 9th had delayed openings.

Across the Poconos, precipitation actually started as rain on the afternoon of the 8th. It changed to freezing rain on the evening of the 8th and to sleet overnight. Precipitation changed to snow during the mid morning on the 9th and ended during the early morning on the 10th. Across the Lehigh Valley, precipitation started as rain early on the 9th. It changed to freezing rain just before sunrise on the 9th with sleet occasionally mixing in. Precipitation changed to snow during the late afternoon on the 9th and ended during the early morning on the 10th. Across Berks County and the northern Philadelphia suburbs, precipitation started as rain early on the 9th. It changed to freezing rain around sunrise on the 9th. Sleet mixed in with the freezing rain during the day on the 9th and the freezing rain changed to snow during the evening on the 9th and ended by the early morning on the 10th. Across the local Philadelphia area, freezing rain occurred during the morning and afternoon of the 9th (along with a little sleet) and spotty freezing drizzle occurred overnight on the 9th.

Representative ice accumulations included 0.20 inches in Huffs Church (Berks County) and Mount Pocono (Monroe County), 0.125 inches in Pennsbury Township (Chester County) and Canadensis (Monroe County), 0.10 inches in Perkasie (Bucks County), Allentown (Lehigh County) and Reading (Berks County), and around 0.05 inches at the Philadelphia International Airport, Pottstown (Montgomery County) and Doylestown (Bucks County).

Representative snow and sleet accumulations included 1.8 inches in Saylorsburg (Monroe County), 1.7 inches in Lehighton (Carbon County), 1.1 inches in Jim Thorpe (Carbon County) and Martins Creek (Northampton County), 1.0 inch in Mount Pocono (Monroe County), 0.6 inches in Hamburg (Berks County), 0.4 inches at the Lehigh Valley International Airport, 0.2 inches in Quakertown (Bucks County) and 0.1 inch in Reading (Berks County).

The wintry mix of precipitation was caused by the combination of waves of low pressure on a frontal boundary that supplied the moisture and precipitation and an arctic high pressure system to the north of the boundary that supplied the low level cold air. As this boundary sagged southward, the precipitation sagged southward with it. At 7 a.m. EST on the 8th, the high pressure system was centered over James Bay and the frontal boundary across the Lehigh Valley. By 7 p.m. EST on the 8th, the frontal boundary moved southwest and cleared all of Eastern Pennsylvania with a wave of low pressure in northwest Pennsylvania. At 7 a.m. EST on the 9th, the frontal boundary was located over the Delmarva Peninsula with a wave of low pressure forming along it and a decaying low pressure system in central Pennsylvania. At 7 p.m. EST on the 9th, the frontal boundary was approaching Cape Hatteras, North Carolina and at 7 a.m. EST on the 10th dropped into northern Florida. By then, waves of low pressure were too far offshore to affect Pennsylvania.

Area forecast discussion, Feb 8, 9:54 PM EST, 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
954 PM EST SUN FEB 8 2015

.SYNOPSIS...
A COLD FRONT WILL SLOWLY DROP SOUTH OF OUR AREA TONIGHT THROUGH
LATE MONDAY. MEANWHILE, AN AREA OF LOW PRESSURE WILL TRACK ALONG
THIS FRONT, PUSHING TOWARD THE MIDDLE ATLANTIC COAST MONDAY AND
EXITING TO THE SOUTH AND EAST OF OUR AREA ON TUESDAY. ANOTHER LOW
PRESSURE SYSTEM WILL ARRIVE ON THURSDAY FOLLOWED BY AN ARCTIC
FRONT. ARCTIC HIGH PRESSURE WILL THEN BUILD INTO THE AREA FOR
FRIDAY AND SATURDAY. A CLIPPER TYPE SYSTEM DROPS DOWN THROUGH THE
REGION LATE SATURDAY INTO SUNDAY, FOLLOWED BY COLD HIGH PRESSURE
FOR EARLY IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
AT 02Z, A WAVE OF LOW PRESSURE WAS LOCATED ALONG A COLD FRONT OVER
THE OHIO VALLEY. THE FRONTAL BOUNDARY EXTENDS SOUTHEASTWARD ACROSS
CENTRAL VA AND THE LOWER DELMARVA. WITH OUR AREA SITUATED ON THE
COOL SIDE OF THE BOUNDARY, COLDER AIR IN THE LOWEST 1500 FT WILL
CONTINUE TO ADVECT IN FROM THE NORTHEAST TONIGHT. THE SOUTHERN
FRINGE OF THE VERY COLD AIR FROM THE ARCTIC HIGH PRESSURE OVER
NORTHERN QUEBEC WAS MOVING INTO SOUTHERN NEW ENGLAND (TEMPS IN THE
TEENS) AND LONG ISLAND (TEMPS IN THE 20S).

USED A BLEND OF THE RAP/HRRR AND NAM (AFTER TAKING INTO ACCOUNT A
DEGREE OR TWO COLD BIAS IN THE NAM) FOR TEMPS, WHICH BOTH HAVE A
FAIRLY GOOD HANDLE OF THE LOW-LEVEL THERMAL STRUCTURE. SUB-FREEZING
OVERNIGHT LOW TEMPS ARE FORECAST FOR MUCH OF CENTRAL AND NORTHERN NJ
AS WELL AS EASTERN PA.

BACKED OFF ON POPS THIS EVENING ACROSS MOST OF THE AREA WITH
MEASURABLE PRECIP CONFINED TO I-80 NORTHWARD. THE LATEST HIRES
MODELS (HRRR, WRF-ARW AND WRF-NMM) SIMULATE A LIGHT BAND OF MAINLY
LIQUID PRECIP OVERSPREADING NORTHEASTERN PA AND NORTHERN NJ
OVERNIGHT. LIGHT ICING IS EXPECTED ACROSS THESE AREAS WITH SURFACE
TEMPS AOB FREEZING. THERE MAY BE SOME VERY LIGHT FREEZING RAIN OR
FREEZING DRIZZLE DEVELOP IN THE COLD SPOTS TO OUR THE NORTH OF
PHILA. THERE IS STILL SOME UNCERTAINTY REGARDING 1) IF PRECIP
REACHES AS FAR SOUTH AS PHILA AND 2) IF TEMPS FALL BELOW FREEZING
BY THE TIME IT DOES. WE WERE ERRED ON THE SIDE OF CAUTION WITH
THIS ONE, ESPECIALLY CONSIDERING THE ONSET TIMING COINCIDING CLOSE
TO THE START OF THE MORNING RUSH. SEE /WSWPHI/ FOR MORE INFORMATION
CONCERNING THE WINTER WX ADVISORIES.

ALSO, MODEL SOUNDINGS SHOW ENOUGH COLD AIR WORKING INTO THE AREA
FOR A SLEET AND SNOW TO MIX IN WITH FREEZING RAIN BY EARLY
MORNING NORTH OF I-80.

FOG HAS ALSO DEVELOPED IN THE COLD SECTOR WITH VSBYS BELOW 1 MILE
ALONG THE PA TURNPIKE AND I-195 CORRIDOR. EXPECT THIS FOG TO SHIFT
SOUTHWARD OVERNIGHT WHILE THE DRIER AIR ERODES THE NORTHERN SIDE OF
THE FOG ZONE.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/...
THE LOW PRESSURE SYSTEM WILL MOVE FROM NRN VIRGINIA TO A POSITION
OFF THE VA CAPES BY MON EVENING. THE PCPN SHIELD WILL CONTINUE
ACROSS THE AREA. P-TYPE ISSUES CONTINUE WITH MOSTLY RAIN SOUTH AND
SOME LIGHT SNOW NORTH AND A LARGE AREA OF MIXED PRECIP ACROSS MUCH
OF THE AREA. COLDER AIR WILL INFILTRATE FROM THE NORTH WITH TEMPS
PROBABLY REMAINING STEADY OR ONLY RISING A FEW DEGREES DURING THE
DAY. PRECIP WILL BECOME MORE FROZEN N TO S THROUGH THE DAY. WINDS
WILL INCREASE DURING THE MORNING...MOSTLY FROM THE E AND THEN WINDS
WILL TURN NE DURING THE AFTERNOON.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
MONDAY NIGHT THROUGH TUESDAY...THE SYSTEM WILL START TO WIND DOWN BY
THIS TIME AND WE WILL SEE PRECIPITATION END FROM NORTHWEST TO
SOUTHEAST. PTYPE WILL VARY BUT WILL CHANGEOVER TO A MIX OF
SNOW/SLEET BEFORE ENDING AS MAINLY SNOW IN OUR AREA. SOME OF OUR
SOUTHERN AREAS MAY END A MIX OF SNOW AND RAIN.

FOR TUESDAY...COLD AIR WILL BE FILTERING DOWN ACROSS OUR AREA AND
WILL CERTAINLY FEEL COLDER, ESPECIALLY ACROSS OUR SOUTHERN AREAS
WHERE TEMPERATURES WILL HAVE BEEN IN THE 40S/50S THE PREVIOUS DAYS.
HIGHS WILL RISE INTO THE 30S ACROSS THE REGION. THE PRESSURE
GRADIENT ACROSS THE REGION WILL REMAIN TIGHT AND THE WIND WILL
BECOME QUITE GUSTY DURING THE DAY.

WEDNESDAY THROUGH SUNDAY...WEAK HIGH PRESSURE WILL NOSE DOWN FROM
THE NORTH ON WEDNESDAY BUT DOES NOT LAST FOR LONG. LOW PRESSURE
TRACKING ACROSS THE GREAT LAKES WILL DIVE SOUTHWARD ACROSS OUR AREA
WEDNESDAY NIGHT INTO THURSDAY, THEN QUICKLY MOVE TO THE NORTH AND
EAST AS IT DEEPENS. NOT A TON OF MOISTURE LOOKS TO ACCOMPANY THIS
FEATURE BUT WE WILL STILL SOME SNOW FALL AS IT MOVES THROUGH.

ARCTIC HIGH PRESSURE WILL BUILD ACROSS THE REGION ON FRIDAY AND THEN
SHIFT OFFSHORE LATER SATURDAY. THE GRADIENT BETWEEN THE BUILDING
HIGH AND DEPARTING LOW WILL BE QUITE STRONG WITH STRONG CAA TAKING
PLACE. THIS WILL RESULT IN WINDY CONDITIONS AND VERY COLD WIND CHILL
VALUES.

A CLIPPER TYPE SYSTEM WILL DROP DOWN INTO OUR AREA FROM THE
NORTHWEST LATE SATURDAY INTO SUNDAY. THIS WILL BRING US ANOTHER
CHANCE FOR SOME SNOW, MAINLY ACROSS THE NORTHERN AREAS. TEMPERATURES
ON THE BACKSIDE OF THIS FEATURE LOOK TO BE BITTERLY COLD WITH GUSTY
WINDS, RESULTING IN VERY COLD WIND CHILLS ONCE AGAIN.

&&

.AVIATION /01Z MONDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

LOW CLOUDS HAVE ALREADY DEVELOPED FROM PHL NORTHWARD, RESULTING IN
IFR/LIFR CIGS. VSBYS HAVE ALSO BEEN REDUCED TO AS LOW AS 1/2 SM AT
PNE AND TTN IN DENSER FOG. EXPECT THE STRATUS TO EXPAND
SOUTHEASTWARD INTO RDG/ILG/ACY LATE THIS EVE AND MIV OVERNIGHT.
LIGHT RA/DZ EXPECTED TO DEVELOP AFTER MIDNIGHT AT ABE AND RDG,
THEN IN THE EARLY MORNING AT TTN/PNE/PHL. TEMPS NORTH OF PHL WILL
BE CLOSE TO FREEZING, SO ADDED FZRA/FZDZ AS WELL.

P-TYPE ISSUES CONTINUE INTO MON WITH MOSTLY IFR ACROSS THE AREA.
NE WINDS INCREASE WITH GUSTS 20KT AROUND DAWN...CONTINUING THROUGH
MONDAY.

OUTLOOK...
MONDAY NIGHT THROUGH TUESDAY...MIXED PRECIPITATION, CHANGING OVER TO
SNOW, IS EXPECTED TO BE TAPERING OFF THROUGH MONDAY NIGHT INTO
TUESDAY MORNING. MVFR CONDITIONS EARLY, THEN BECOMING VFR. NORTH
NORTHWEST WINDS AROUND 10 TO 15 KNOTS WITH GUSTS UP TO 20 KNOTS
THROUGH THE AFTERNOON.

WEDNESDAY...MAINLY VFR CONDITIONS EXPECTED WITH INCREASING
CLOUDINESS TOWARD THE AFTERNOON/EVENING. NORTH TO NORTHWEST WINDS
BECOMING WEST, THEN SOUTHWEST LATE.

THURSDAY...SOME SNOW SHOWERS, WITH LOWER CEILINGS AND VISIBILITIES,
ARE POSSIBLE AS A LOW PRESSURE SYSTEM CROSSES THE REGION. OTHERWISE,
MAINLY VFR CONDITIONS EXPECTED. WEST TO NORTHWEST WINDS AROUND 10 TO
15 KNOTS WITH GUSTS UP TO 20 KNOTS.

FRIDAY...VFR CONDITIONS ARE EXPECTED. NORTHWEST WINDS INCREASING TO
15 TO 20 KNOTS WITH GUSTS UP TO 30 KNOTS, ESPECIALLY SOUTH AND EAST
OF KPHL.

&&

.MARINE...
WINDS AND SEAS NEAR SCA CRITERIA AT 930 PM OVER THE NNJ WATERS AS
COLDER AIR ARRIVES.

WE MAY BE STARTING THE SCA TONIGHT OVER THE NJ WATER AND THEN THE
DE WATERS MONDAY AS NORTHEAST WINDS INCREASE. WINDS ON THE BAY
WILL PROBABLY HOLD A FEW KNOTS LOWER. SEAS ACROSS THE NRN WATERS
WILL INCREASE TO AROUND 5-7FT. RAIN WILL OVERSPREAD THE AREA LATE
TONIGHT AND LAST INTO MONDAY. AREAS OF FOG ALSO EXPECTED.

OUTLOOK...
MONDAY NIGHT THROUGH TUESDAY...A TIGHTENING PRESSURE GRADIENT IN
RESPONSE TO THE DEPARTING LOW TO OUR EAST AND A BUILDING HIGH TO OUR
WEST WILL CAUSE WINDS TO GUST IN EXCESS OF 25 KNOTS AND THE
POSSIBILITY OF 34 KNOTS GUSTS IS POSSIBLE. CONFIDENCE IS HIGHER THAT
GALE FORCE GUSTS WILL OCCUR OVER OUR SOUTHERN WATERS BUT THE
POTENTIAL FOR GALE FORCE GUSTS EXISTS ACROSS ALL OF OUR WATERS, WITH
THE EXCEPTION OF THE UPPER DELAWARE BAY.

WE HAVE ISSUED A GALE WATCH FOR MONDAY NIGHT INTO TUESDAY EVENING
FOR OUR OCEAN WATERS AND THE LOWER DELAWARE BAY.

WEDNESDAY...SEAS AND WINDS WILL GRADUALLY START TO DIMINISH AND
SHOULD FALL BELOW SMALL CRAFT ADVISORY CRITERIA BY THE AFTERNOON.

THURSDAY AND FRIDAY...ANOTHER SYSTEM WILL CROSS THE REGION THURSDAY
FOLLOWED BY HIGH PRESSURE FOR FRIDAY. THE GRADIENT BETWEEN THESE
SYSTEMS WILL ONCE AGAIN CAUSE WINDS TO BECOME GUSTY WITH THE
POTENTIAL FOR GALE FORCE GUSTS TO OCCUR. FREEZING SPRAY WILL ALSO
REMAIN POSSIBLE DURING THIS TIME.

&&

.CLIMATE...
WE EXPECT TO BEGIN POSTING RECORD LOWS EARLY THIS WEEK FOR 2 OR
MORE OF THE DAYS IN THE FEBRUARY 13-16 TIME FRAME AS TWO RATHER
STRONG COLD SURGES OF AIR MOVE INTO OUR AREA. THESE COLD SURGES
WILL BE USHERED IN BY DEVELOPING CLIPPERS...A RATHER IDEAL SITUATION
APPEARS TO DEVELOPING FOR A VERY COLD 5 DAY PERIOD FRIDAY-TUESDAY.
