What happened

The episode as NWS PHI wrote it up.

A wintry mix of precipitation including some heavy snow fell across Eastern Pennsylvania on the 22nd. The heaviest snow occurred near the New Jersey border. Precipitation started as snow throughout the area around or just after Midnight EST on the 22nd. As warmer air moved in aloft, precipitation changed quickly to sleet and freezing rain during the morning in and around Philadelphia, around Noon EST in Berks County, the Lehigh Valley and the far northern Philadelphia suburbs and during the late afternoon and early evening in the Poconos. Precipitation changed to plain rain in and around the local Philadelphia area during the afternoon of the 22nd, but remained intermittent light freezing rain elsewhere until the event ended during the evening of the 22nd. Snow and sleet accumulations averaged 3 to 6 inches. Ice accretions were generally around one-tenth of an inch.

The wintry precipitation caused many traveling problems around the region. In and around the Philadelphia area many suburban schools were closed for the day. In Philadelphia, the Philadelphia International Airport experienced delays of up to four hours. Peco Energy reported less than 100 customers had lost power during the storm around the Philadelphia Metropolitan area. Philadelphia’s transit agency reported widespread delays on its buses, trolley, and train lines. The Philadelphia public and parochial schools opened during the morning, but then closed at Noon EST. SEPTA trains experienced delays of up to 30 minutes and the R6 Bala Cynwyd service was suspended. In Chester County, West Chester and Immaculata Universities were also closed. There were numerous reports of spinouts and cars on the shoulder due to slippery conditions. At 9:45 AM EST near Phoenixville, two young boys suffered minor injuries when the sled they were on went into the road and was hit by a passing car. In Bucks County, police reported several cars slid off the road and into ditches and each other, especially across the upper portions of the county, during the morning of the 22nd. Numerous accidents were also reported in Montgomery County.

Across Berks County and the Lehigh Valley: a tractor-trailer jackknifed during the early morning hours, which temporarily shut down one lane of westbound Interstate 78 between Exit 45 (Route 863) in Lehigh County and Exit 40 (Route 737) in Berks County. The truck hit the center barrier before it jackknifed across the westbound lanes about 4:15 AM EST. The highway was reopened at about 7:10 AM EST. In Berks County, many of the roads became icy once again during the night of the 22nd. At about 1030 PM EST, police responded to an accident which involved a car that rolled onto its side on U.S. Route 422 in Lower Heidelberg Township. Someone was trapped in the wreckage, however it was unknown if anyone was injured. Several schools were closed on the 22nd. In the Lehigh Valley: The Allentown Police Department reported a few minor traffic accidents due to the slippery conditions. In Northampton County the on-and off-ramps to Pennsylvania State Route 33 from Pennsylvania State Route 248 were closed around 5:00 AM EST in Lower Nazareth Township because a jackknifed tractor-trailer. The ramps reopened about 7:00 AM EST. PPL reported 23 customers were without power at 5:30 PM EST on the 22nd in Lower Saucon Township because of vehicle accidents.

In the Poconos all the Carbon County schools were closed. In Monroe County, a snow-covered road was blamed for a two-vehicle crash that occurred at about 2:33 AM EST along SR209 at Horseshoe Drive in Polk Township. Mainly minor injuries were reported.

Actual accumulations included 7.5 inches in Delaware Water Gap (Monroe County), 6.3 inches in Marshalls Creek (Monroe County), 6.0 inches in Bangor and Walnutport (Northampton County), 5.5 inches in Quakertown (Bucks County) and Albrightsville (Carbon County), 5.2 inches in Allentown (Lehigh County) and Pine Valley (Philadelphia County), 5.0 inches in Levittown (Bucks County), 4.8 inches in Willow Grove (Montgomery County), 4.5 inches in Villanova (Delaware County), 4.0 inches in Bechtelsville (Berks County), 3.5 inches in Tredyffrin (Chester County), 3.4 inches in Palmerton (Carbon County), 3.3 inches in Royersford (Montgomery County), 3.2 inches in Reading (Berks County) and at the Philadelphia International Airport, 3.0 inches in Downingtown (Chester County), Conowingo (Cecil County), 0.8 inches in Millington (Kent County), 0.6 inches in Denton (Caroline County) and 0.4 inches in Easton (Talbot County).

The wintry mix was caused by a low pressure system that formed along the Gulf Coast States during the afternoon of the 21st. This low pressure system moved northeast and reached Mississippi on the morning of the 22nd and the Tennessee Valley during the early afternoon of the 22nd. A secondary low pressure formed along the South Carolina coast that morning and reached Cape Hatteras early that afternoon. The secondary low pressure system continued to move northeast and by 7 p.m. EST on the 22nd was located about 125 miles east of Long Beach Island, New Jersey. It passed just south of Nova Scotia overnight. The surface high pressure system that preceded the low left a cold and dry air mass in place for precipitation to start as snow. Since the high pressure system moved offshore, enough warm air in came in from the Atlantic to change the precipitation over to plain rain near Philadelphia. But, farther inland, northeast winds fed colder air into the state and prevented temperatures from rising above freezing.

Area forecast discussion, Feb 21, 5:31 PM EST, 5 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
531 PM EST THU FEB 21 2008

.SYNOPSIS...
LOW PRESSURE OVER THE GULF COAST STATES WILL MOVE TO THE TENNESSEE
VALLEY TONIGHT. SECONDARY LOW PRESSURE WILL FORM OFF THE CAROLINA
COAST FRIDAY AS THE LOW TO THE WEST DISSIPATES. THE NEW AREA OF LOW
PRESSURE WILL THEN INTENSIFY SLOWLY AS IT HEADS NORTHEAST AND OUT TO
SEA FRIDAY NIGHT. HIGH PRESSURE IS FORECAST TO GRADUALLY BUILD IN
FROM THE WEST OVER THE WEEKEND AND INTO MONDAY. A LOW PRESSURE AREA
SHOULD MOVE THROUGH THE OHIO VALLEY TUESDAY AND MOVE OFF THE COAST
TUESDAY NIGHT.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
IT WAS DECIDED TO UPGRADE THE WINTER STORM WATCH TO A WARNING FOR
MOST OF THE ZONES THAT HAD BEEN WATCHED, AND TO ISSUE A WINTER
WEATHER ADVISORY FOR THE REST OF THE AREA DUE TO THE ADVANCING
STORM SYSTEM. IT IS FORECAST TO BRING A MIXED PRECIPITATION EVENT
FOR THE SOUTHEASTERN AREAS, A MAINLY SNOW AND SLEET EVENT WELL
NORTHWEST, AND A MESSY MIX IN BETWEEN.

ESSENTIALLY, THE COLDER GFS AND EUROPEAN MODELS WERE ACCEPTED FOR
THIS EVENT FOR THE WARNING AREA, BASED ON RECENT PAST PERFORMANCE
AND EXPECTED LOW LEVEL WIND AND THERMAL PROFILES.

WARM ADVECTION HIGH CLOUDS WERE IN THE PROCESS OF ADVANCING ON
THE AREA FROM THE WEST-SOUTHWEST AT LATE AFTERNOON, AND THESE WILL
LOWER OVERNIGHT. THE ONSET OF PRECIPITATION IS FORECAST FOR
SHORTLY AFTER MIDNIGHT FOR OUR WESTERN ZONES, WHICH IS ABOUT WHAT
THE FASTER GFS HAS, WITH SNOW (WHICH IS THE PRECIPITATION TYPE
THAT WILL DEVELOP TONIGHT BASED ON MODEL SOUNDINGS) SPREADING TO
OUR NORTHEASTERN ZONES BY VERY LATE TONIGHT. ALL AREAS SHOULD BE
SNOWING BY MORNING, WITH ACCUMULATIONS FROM AN INCH OR TWO
SOUTHWEST TO LESS THAN AN INCH NORTHEAST.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/...
THINGS REALLY START TO GET INTERESTING IN THE FRIDAY PERIOD. WARM
AIR SHOULD RATHER QUICKLY MOVE INTO OUR FAR SOUTHEASTERN ZONES,
AND BY LATE MORNING, RAIN SHOULD BE MIXING IN, WITH A CHANGEOVER TO
PLAIN RAIN COMPLETED BY EARLY AFTERNOON. THIS WILL HOLD SNOW
AMOUNTS DOWN TO AN INCH OR POSSIBLY TWO, BUT IT WAS FELT THAT THE
IMPACT ON THE MORNING COMMUTE ALONE DICTATED THAT AN ADVISORY BE
IN PLACE.

FURTHER NORTHWEST, SAY FROM THE CENTRAL NEW JERSEY COAST
SOUTHWESTWARD TO CENTRAL DELAWARE AND OUR SOUTHERN NORTHEAST
MARYLAND COUNTIES, IT WILL TAKE SOME TIME FOR THE CHANGEOVER TO
OCCUR, SO SNOW AMOUNTS COULD BE A LITTLE HIGHER AND BE AUGMENTED
BY A PERIOD OF SLEET TOO. IT WAS FELT THAT SURFACE TEMPERATURES
WILL BR RISING, TOO, SO FREEZING RAIN SHOULD NOT REAR ITS UGLY
HEAD HERE.

HOWEVER, FOR THE I-95 AND ROUTES 295 AND 1 CORRIDOR, SURFACE WINDS
MAINTAINING OR BACKING TO A NORTHEAST DIRECTION MAY KEEP COLDER
AIR IN PLACE FOR A LONGER TIME, AND THIS LEADS TO A THREAT OF
SLEET AND ESPECIALLY FREEZING RAIN. THIS THREAT IS ENHANCED FOR
THE NORTHERN AND WESTERN PHILADELPHIA SUBURBS, WHERE THE 32 DEGREE
ISOTHERM ON THE EUROPEAN MODEL IS ALONG THE DELAWARE RIVER, AND
THE LATEST (18Z) GFS MOS GUIDANCE IS A DEGREE COLDER ON THE 3
HOURLY TEMPERATURES (AS WELL AS THE MAXIMUM TEMPERATURE) AS COMPARED
WITH ITS PREVIOUS RUN, AND AGAIN SHOWING NORTHEAST WINDS. INTERNAL
GUIDANCE FROM HPC AGREES WITH THIS, SHOWING A SWATH OF 0.10 TO
0.25 INCH ICING IN OUR NORTHERN AND WESTERN ZONES UP THROUGH THE
LEHIGH VALLEY, WITH LESS ICE FURTHER NORTH AS MORE SNOW AND SLEET
PREDOMINATE. LIQUID PRECIPITATION AMOUNTS ARE FORECAST TO BE IN
THE 1/2 TO 3/4 OF AN INCH RANGE, LOCALLY 1 INCH. SO, SNOW AMOUNTS
ARE SHADED FROM AN INCH OR TWO SOUTH, AS MENTIONED, TO 2 TO 4
INCHES IN THE ADVISORY AREA IN THE ROUTE 1 AND I-95 CORRIDOR, UP
TO 4 TO 8 INCHES FOR OUR FAR NORTHERN ZONES WHERE COLDER
TEMPERATURES WILL LEAD TO HIGHER ACCUMULATIONS WITH LESS SLEET AND
RAIN. LATER FORECASTERS ARE URGED TO CONSIDER UPGRADING ADVISORY
COUNTIES ON THE CUSP OF THE WARNING AREA TO A WARNING (SUCH AS
MIDDLESEX NJ, CECIL MD, NEW CASTLE DE, AND DELAWARE PA) IF IT
APPEARS THAT ICE AMOUNTS WILL BE ENHANCED DUE TO LOWER FRIDAY
AFTERNOON TEMPERATURES.

GENERAL PRECIPITATION SHOULD START TO TAPER OFF LATER FRIDAY
EVENING, BUT COLDER AIR MOVING BACK SOUTH AND EAST COULD KEEP SOME
LIGHT SNOW FOR A PERIOD OR TWO, ALONG WITH SOME LIGHT DRIZZLE OR
FREEZING DRIZZLE AS MODEL SOUNDINGS DECREASE THE SATURATION. THE
WARNINGS AND NORTHERN ADVISORIES WERE DISCONTINUED AT 06Z
SATURDAY, BUT WERE ENDED AT LATE AFTERNOON FOR THE SOUTHEASTERN
ADVISORY AREA AND AS EARLY AS EARLY FRIDAY AFTERNOON FOR THE FAR
SOUTHEAST.

OTHERWISE, HIGH PRESSURE WILL GRADUALLY BUILD IN LATER SATURDAY.
UNTIL THEN, THERE COULD BE ANOTHER WEAK SURGE OF PRECIPITATION,
AND, BASED ON LOW LEVEL TEMPERATURES, IT COULD BE SNOW, OR RAIN OR
SNOW.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
HIGH PRESSURE WILL PROVIDE FAIR WEATHER SUNDAY NIGHT INTO MONDAY
NIGHT. MOISTURE RUNNING AHEAD OF LOW PRESSURE MOVING IN FROM THE
WEST WILL CAUSE INCREASING CLOUDINESS MONDAY NIGHT WITH THE CHANCE
FOR A FEW SNOW SHOWERS NORTH LATE. THE LOW IS EXPECTED TO TRACK
NORTHEAST INTO NEW YORK STATE TUESDAY NIGHT. THIS WILL ALLOW MILD
AIR TO OVERSPREAD THE FORECAST AREA AND BRING RAIN TUESDAY. THE
RAIN MAY BE MIXED WITH SNOW NORTH, ESPECIALLY EARLY IN THE DAY.
THE COLD FRONT ASSOCIATED WITH THE LOW WILL CROSS THE AREA TUESDAY
NIGHT BRINGING COLDER AIR BACK INTO THE REGION. THE PRECIPITATION
MAY CHANGE BACK OVER TO SNOW OR FLURRIES MOST AREAS BEFORE ENDING
WEDNESDAY MORNING. AS HIGH PRESSURE PUSHES IN FROM THE WEST AND
THE LOW EXISTS TO THE NORTHEAST, A COLD NORTHWEST FLOW WILL SET
IN. THIS WILL CONTINUE THE THREAT OF SNOW SHOWERS AND FLURRIES
FOR THE NORTHERN MOUNTAINS LATER WEDNESDAY INTO THURSDAY. ELSEWHERE
FAIR COLD WEATHER WILL PREVAIL.

&&

.AVIATION /22Z THURSDAY THROUGH TUESDAY/...
FOR KRDG, KABE, KTTN, KPNE, KPHL, KILG, KMIV AND KACY, THE CLEAR
SKIES WILL GIVE WAY TO HIGH CIRRUS THIS EVENING AND THEN A LOWERING
OF THE CLOUDS OVERNIGHT. SNOW IS EXPECTED TO DEVELOP BETWEEN 07-10Z
FROM WEST TO EAST. A PERIOD OF MODERATE SNOW IS ANTICIPATED FROM
10-14Z. THE SNOW SHOULD CONTINUE THROUGH THE 18Z AT ABE/RDG. AT
TTN/PNE/PHL/ILG...THE SNOW SHOULD CHANGE TO FZRAPL 14-16Z AND THEN
TO RAIN AROUND 18Z. TTN MAY HOLD FREEZING PCPN UNTIL 18Z.
ACY/MIV...THE TIME OF ANY MODERATE SNOW SHOULD BE ONLY AN HR OR TWO
BEFORE THE PCPN CHANGES TO RAIN BY 15Z. HOWEVER, EVEN ACY/MIV MAY
SEE A PERIOD OF FREEZING RAIN AND SLEET TOO.

ONCE THE PCPN ARRIVES, VFR CONDITIONS WILL DETERIORATE RAPIDLY TO
IFR WITH SOME LIFR CONDITIONS POSSIBLE IN ANY PERIODS OF HEAVIER
SNOW.

FRIDAY AFTN...IFR CONDITIONS ARE ANTICIPATED TO CONTINUE, AND EVEN
ABE/RDG SHOULD SEE MIXED PCPN. FRIDAY EVENING, THE PCPN COULD
TRANSITION BACK TO SNOW/SLEET AND FZRAIN DOWN TO NEAR PHL.

LONGER RANGE...VFR CONDITIONS SHOULD RETURN SATURDAY, ALTHOUGH SOME
MVFR CONDITIONS COULD LINGER INTO SAT MORNING. THE NEXT THREAT OF
SIGNIFICANT PCPN IS NEXT TUESDAY .

&&

.MARINE...
SCA WERE DISCONTINUED THIS MORNING. ALTHOUGH WE WILL HAVE AN AREA OF
LOW PRESSURE TO DEAL WITH ON FRIDAY AND FRIDAY NIGHT, THE GRADIENT
ASSOCIATED WITH THE LOW LOOKS TOO WEAK FOR ME TO ISSUE AND SCA
HEADLINES AT THIS POINT. BY FRIDAY NIGHT, ONCE THE NEW LOW
REDEVELOPS OFF THE COAST, SEAS MIGHT INCREASE TO 5 FT ON THE OCEAN
LATE FRIDAY NIGHT OR SAT MRNG.

HIGH PRESSURE IS EXPECTED TO BUILD IN FROM THE WEST FOR SATURDAY
AFTERNOON, SUNDAY AND MONDAY. ANOTHER AREA OF LOW PRESSURE COULD
ALLOW WINDS AND SEAS TO REACH SCA CRITERIA LATE TUE OR TUE NIGHT.
