What happened

The episode as NWS PHI wrote it up.

Snow fell across Eastern Pennsylvania from the evening of the 1st into the evening of the 2nd. Snowfall averaged four to eight inches across the region, with some locally higher amounts around Philadelphia. Many snow emergencies were declared. The combination of strong winds and heavy snow made travel difficult and made it tough for road crews to keep thoroughfares opened. Numerous accidents occurred and major interstates were snarled. There were many fender benders, spin-outs and slides into other vehicles. The Mid-Atlantic AAA responded to 2,600 calls for assistance throughout their region. Most schools were closed on Monday March 2nd. Some universities and colleges in and around Philadelphia also cancelled classes. Many meetings and sporting events were postponed on the 2nd.

Snow began across the local Philadelphia area during the early evening of the 1st and spread north through the Poconos shortly after midnight EST on the 2nd. The heaviest snow associated with the nor'easter occurred farther to the east. Snow ended during the late afternoon, except during the evening in the Poconos.

The worst reported accidents occurred along Interstate 78 in Berks County on the 2nd. On Westbound Interstate 78 about 8 a.m. EST, a one vehicle accident closed one lane for about 45 minutes. At about 9 a.m. EST, on eastbound Interstate 78, two vehicles collided and one person was injured. Within the hour another seven multi-vehicle accident near exit 35 (Lenhartsville) occurred. A 45-year-old man and a 42-year-old woman were injured. A vehicle that stopped before the crash was rear ended twice. A thirteen mile stretch of the eastbound interstate was closed from Shartlesville to Krumsville until 420 p.m. EST. The eastbound closures for a little while extended to Pennsylvania State Route 100 in Lehigh County. Farther to the west at 1030 a.m. EST, two tractor trailers collided on eastbound Interstate 78 and forced the closure from exits 19 (near Strausstown) to 23 (Shartlesville). Around Noon EST, two separate four vehicle collisions occurred on westbound Interstate 78. A tractor-trailer that stopped before one accident was struck by another vehicle and the driver was injured. The westbound side of the interstate was closed until 845 p.m. EST from exit 40 (Krumsville) to exit 23 (Shartlesville). Elsewhere in Berks County, many accidents were reported in Jefferson, Richmond and Wyomissing. In Reading, the West Shore Bypass (U.S. Route 422) was slowed to a crawl after a serious accident. | |In and around the local Philadelphia area, SEPTA reported day long 15 minute delays on their commuter rail lines. Amtrak had to cancel or cut back on a dozen Northeast Corridor trains. PennDot reported more than 50 vehicles became stuck on the interstates in and around the city. A tractor-trailer jack-knifed on the Schuylkill Expressway near Gladwyne (Montgomery County) forcing the closure of the westbound lanes for about an hour on the morning of the 2nd. About 245 flights were cancelled at Philadelphia International Airport. In Bucks County, a police officer was injured in a traffic accident in Bensalem. In Delaware County, traffic accidents caused about 3,000 homes and businesses to lose power.

In the Lehigh Valley, a serious accident that resulted in an injury occurred in Wilson Borough (Northampton County). In the Poconos, two tractor-trailers collided on Interstate 80 westbound in Carbon County. Two injuries occurred and the interstate was closed. In Monroe County, accidents were reported in Lehman, Jackson, Long Pond, East Stroudsburg and Hamilton. In Jackson Township, a woman injured her hand after her vehicle skidded off the road and into a tree.

Snowfall totals included 9.5 inches in Perkasie (Bucks County), 9.0 inches in Williams Township (Northampton County), 8.4 inches in Coatesville (Chester County), 8.3 inches at the Philadelphia International Airport, 8.0 inches in East Nantmeal (Chester County), Villanova (Delaware County) and Royersford (Montgomery County), 7.5 inches in Morgantown (Berks County), 7.0 inches in Drexel Hill (Delaware County) and the Roxborough section of Philadelphia, 6.7 inches in Furlong (Bucks County), 6.3 inches in Wynnewood (Montgomery County), 6.0 inches in Exton (Chester County) and Boothwyn (Delaware County), 5.5 inches in Doylestown (Bucks County) and Emmaus (Lehigh County), 5.0 inches in Tobyhanna (Monroe County), 4.2 inches in Reading (Berks County), 4.1 inches at the Lehigh Valley International Airport and 4.0 inches at Delaware Water Gap (Monroe County) and Tatamy and Forks Township(Northampton County).

The winter storm was caused by a nor'easter that moved east of the region. The nor'easter low pressure system moved from the Georgia and South Carolina border at 7 a.m. EST on the 1st to about 150 miles east of the Atlantic City coast at 7 a.m. EST on the 2nd. It was passing through the Canadian Maritimes during the morning of the 3rd. Heavy snow bands associated with the gravity wave occurred during the pre-dawn hours on the 2nd when most of the heaviest snow fell.

Area forecast discussion, Mar 1, 3:51 PM EST, 3 hours 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
351 PM EST SUN MAR 1 2009

.SYNOPSIS...
LOW PRESSURE WILL MOVE NORTHEAST ALONG THE EASTERN SEABOARD
TONIGHT AND THEN PASS TO THE EAST OF NEW JERSEY MONDAY BEFORE
MOVING UP OVER MARITIME CANADA LATE ON MONDAY NIGHT. HIGH
PRESSURE IS THEN FORECAST TO BUILD IN FROM THE WEST FOR THE MID
WEEK PERIOD. A WARM FRONT FROM THE SOUTHWEST IS FORECAST TO ARRIVE
LATE IN THE WEEK.

&&

.NEAR TERM /THROUGH MONDAY/...
THE WINTER STORM WILL ARRIVE THIS EVENING.

SNOW SLEET AND RAIN WILL CONTINUE TO HEAD NORTHWARD ACROSS THE
EASTERN MARYLAND SHORE AND CENTRAL DELAWARE THIS EVENING. IT WILL
CONTINUE TO MOVE NORTHWARD AND SHOULD ARRIVE IN THE FORM OF ALL
SNOW WHEN IT GETS TO WILMINGTON DELAWARE AND THE PHILADELPHIA
METROPOLITAN AREA BETWEEN 5 AND 7 PM. THE SNOW WILL THEN SPREAD
NORTHWARD THROUGHOUT THE AREA BY 10 PM.

MODELS ARE IN GENERAL AGREEMENT WITH THIS SYSTEM WITH SOME SUBTLE
DIFFERENCES, MAINLY IN PTYPE SOUTH. FOLLOWING TRENDS AND AFTER A
LOOK AT THE GFS WHICH SHOWS SOME WARMING AT H8 IN THE MIDDLE OF
THE NIGHT, IT LOOKS AS THOUGH THERE WILL BE SOME MIXED PCPN ALONG
THE COAST AND EXTREME SOUTHERN DELAWARE FOR A GOOD PORTION OF THE
EVENT EARLY TONIGHT. EVEN SO, THE PCPN DOWN THERE SHOULD START AS
A MIXED PCPN EVENT, THEN TURN TO SNOW FOR AWHILE THIS EVENING,
THEN MIX AGAIN OVERNIGHT BEFORE TURNING TO ALL SNOW EARLY MONDAY
MORNING. OVER THE REST OF THE AREA, PROFILES INDICATE A SNOW
EVENT, HOWEVER, SOME LEFTOVER WARMTH FROM THE DAYTIME COULD ALLOW
FOR SOME SLEET OR EVEN SOME LIGHT RAIN AT THE ONSET OF PCPN THIS
EVENING UP TO WILMINGTON. FARTHER NORTH...ALL SNOW IS FORECAST.

AS ARCTIC HIGH PRESSURE TRIES TO BUILD IN FROM THE WEST WHILE THE
LOW MOVES BY TO THE EAST, THE WINDS INCREASE LATE TONIGHT AND
REMAIN GUSTY ON MONDAY. THIS COMBINED WITH THE SNOW SHOULD MEAN
BLOWING AND DRIFTING SNOW LATE TONIGHT AND MONDAY. THE SNOW MAY
START OUT MOIST THIS EVENING, BUT IT SHOULD BECOME DRY AND
FLUFFY LATE TONIGHT ALLOWING FOR IT TO GET BLOWN AROUND BY THE
WINDS LATER TONIGHT AND MONDAY.

SNOWFALL AMOUNTS WERE TWEEKED A BIT LOWER THIS CYCLE AS QPF
AMOUNTS DONT LOOK QUITE AS HIGH AS PREVIOUSLY FCST. THE SNOW
SHOULD FALL HEAVY AT TIMES TONIGHT, BUT THERE LOOKS LIKE THERE MAY
BE A LULL IN THE PCPN LATE AS WE LOSE SOME OF THE INFLUENCE OF THE
OFFSHORE LOW. HOWEVER, AS THE UPPER LOW CROSSES MONDAY MORNING,
THERE COULD BE SOME MESOSCALE BANDING AND THIS COULD ENHANCE
SNOWFALL RATES ONCE AGAIN. THEREFORE, EVEN THOUGH SNOW MAY LIGHTEN
UP LATE, WE SHOULD NOT THINK THE STORM IS OVER.

I DID NOT DROP SNOWFALL AMOUNTS THAT MUCH DUE TO THE LOWER QPF
FCST SINCE I EXPECT SNOW RATIOS TO BE AS HIGH AS 12:1 AND MAYBE
15:1.

ONE LAST ITEM, I WOULD NOT BE SURPRISED TO HEAR ABOUT ISOLATED
EMBEDDED TSTMS. IF IT HAPPENS, IT COULD OCCUR AT 2 DIFFERENT
TIMES, ONCE WITH THE STRONG LIFT MOVING NORTH FROM VA/NC AND AGAIN
AS THE UPPER LOW MOVES THROUGH ON MONDAY MORNING.

BEHINE THE UPPER LOW...ON MONDAY AFTERNOON, THE SNOW SHOULD TAPER
OFF TO SCATTERED SNOW SHOWERS. MEANWHILE, THE ARCTIC HIGH BUILD IN
FROM THE WEST AND BITTERLY COLD AIR ARRIVES. TEMPERATURES MAY FALL
THROUGH THE DAY ON MONDAY WITH THE COLD ADVECTION AND WIND CHILLS
WILL MAKE IT FEEL BELOW ZERO NORTH AND

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
WITH A FRESH SNOW COVER EXPECTED TO BE IN PLACE, AND THE MAV/MET
GUIDANCE INITIALLY WITHOUT THE SNOW COVER, THE COLDER OF THE
GUIDANCE WAS USED TO FCST TEMPERATURES AS ARCTIC HIGH PRESSURE
BUILD IN FROM THE WEST. WHAT MIGHT KEEP TEMPERATURES FROM GETTING
EVEN COLDER WILL BE THE GUSTY WINDS THAT SHOULD PREVENT IDEAL
RADIATION FROM MAKING IT EVEN COLDER AT NIGHT ON MONDAY NIGHT.
HOWEVER, AS THE AIRMASS MODIFIES A BIT TUESDAY NIGHT, THE HELPFUL
RADIATIVE EFFECTS OF THE SNOW SHOULD MAKE IT AS COLD OR MAYBE
COLDER THAN MONDAY NIGHT.

OTHERWISE, THE HIGH BUILDING IN FROM THE WEST SHOULD BRING MOSTLY
CLEAR SKIES.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
TEMPERATURES CONTINUE TO REBOUND AS AN AREA OF HIGH PRESSURE MOVES
ACROSS THE EASTERN UNITED STATES MIDWEEK, ALLOWING FOR SOME NICE DRY
WEATHER. TEMPERATURES WEDNESDAY WILL BE MAINLY IN THE 30S BUT WILL
WARM ON THURSDAY AND FRIDAY, NEAR NORMAL CONDITIONS, INTO THE 40S
ACROSS THE REGION.

AS THE HIGH MOVES OFF TO THE SOUTHEAST AND EVENTUALLY OFF THE
CAROLINA COAST, A LOW PRESSURE SYSTEM WILL DEVELOP OVER THE CENTRAL
PLAINS. THE WARM FRONT FROM THIS LOW WILL APPROACH THE REGION FROM
THE SOUTHWEST LATE THURSDAY, CROSSING ON FRIDAY. THE FRONT WILL THEN
BE PUSHED BACK SOUTH AS A COLD FRONT SATURDAY. THIS SYSTEM WILL
BRING A CHANCE FOR RAIN AND SNOW THROUGH THE WEEKEND. ANOTHER SYSTEM
WILL DEVELOP IN THE PLAINS STATES AND WORK ITS WAY EASTWARD FOR THE
END OF THE WEEKEND.

WITH THE AMOUNT OF ACTIVITY IN THE NEAR TERM, WE CHOSE TO USE HPC
GUIDANCE WITH CONTINUITY THROUGHOUT THE FORECAST PERIOD.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

A MODERATE NOREASTER WILL BE AFFECTING THE AREA TONIGHT AND MONDAY.
THE CURRENT MVFR CONDS AT MOST OF OUR TAF SITES WILL BE
DETERIORATING TO IFR THIS EVENING AS THE STORM WINDS UP...AND
EVENTUALLY LIFR OVERNIGHT WITH VSBYS 1/2 TO 3/4 MILES IN MODERATE
SNOW AND CIGS BELOW 1000 FT. THIS IS EXPECTED TO BE PREVAILING COND
FOR MUCH OF THE NIGHT. STRONG NNE WINDS WILL CAUSE PROBLEMS WITH
BLOWING SNOW. RDG AND ABE ARE FARTHER FROM THE STORM CENTER AND
SHOULD LESS SEVERE CONDS AND FOR A SHORTER TIME.

CONDS SHOULD IMPROVE SOMEWHAT LATE TONIGHT AS THE MAIN BAND OF SNOW
MOVES NORTH OF THE AREA. HOWEVER...SOME LIGHT TO OCCASIONALLY MDT
SNOW SHOULD CONT THROUGH THE MORNING...AND STRONG GUSTY WINDS WILL
CONTINUE FROM THE NNW RESULTING IN BLOWING SNOW. BY MIDDAY THE
PRECIP SHOULD BE MOSTLY OVER AND CONDS SHOULD IMPROVE TO HIGH MVFR
OR VFR DURG THE AFTERNOON. STRONG NW WINDS WILL CONTINUE HOWEVER
WITH GUSTS 25 TO 30 KT.

OUTLOOK...
WINDS SHOULD DIE DOWN BY WEDNESDAY AS HIGH PRESSURE MOVES OVER THE
EAST COAST. WEATHER SHOULD BE GENERALLY BENIGN FOR THE REST OF THE
WEAK.

&&

.MARINE...
A MODERATE NOREASTER WILL BE HEADING ACROSS CAPE HATTERAS THIS
EVENING AND THEN NE TO NEAR CAPE COD BY TOMORROW AFERNOON. THE
SURFACE LOW CENTER IS NOT PARTICULARLY DEEP BUT THERE IS A STRONG
PRESSURE GRADIENT BETWEEN THE LOW AND HIGH PRESSURE CENTERED N OF
THE GRTLKS. THUS NE WINDS ARE FCST TO INCREASE TO GALE FORCE TONIGHT
AS THE LOW MOVES OFF CAPE HAT AND THEN BACK TO THE NW AS THE LOW
MOVES N OF THE COASTAL WATERS MONDAY MORNING. WINDS WILL DECREASE
SMWHT LATER MON AFTERNOON BUT STRONG SMALL CRAFT CONDS WILL LIKELY
CONTINUE THROUGH MONDAY NIGHT AND MUCH OF TUESDAY AS THE HIGH
PRESSURE BUILDS IN FROM THE WEST.

SEAS ARE ALREADY RUNNING RATHER HIGH...11 FT AT THE DEL BAY BUOY
44009...BECAUSE OF PERSISTENT NE WINDS. INCREASING WINDS WILL BUILD
THE SEAS FURTHER TONIGHT. AS WINDS BACK TO THE NW MON MORNING THE
FETCH BECOMES SHORTER AND SEAS SHOULD BEGIN TO SUBSIDE. SEAS WILL
CONTINUE TO GRADUALLY DIMINISH THROUGH TUE AND TUE NIGHT ALONG WITH
THE WINDS.

MIXED PRECIP WILL DEVELOP OVER THE FORECAST WATERS THIS EVENING AND
THEN BECOME MOSTLY SNOW OVERNIGHT. HEAVY SNOW AT TIMES WILL RESULT
IN SEVERELY RESTRICTED VSBYS.

&&

.TIDES/COASTAL FLOODING...
SOME MINOR COASTAL FLOODING IS EXPECTED TONIGHT AROUND THE TIME OF
HIGH TIDE. TIDES ARE ALREADY RUNNING 1 TO 1.5 FT ABOVE NORMAL DUE TO
THE SUSTAINED NE WINDS. STORM SURGE IS FCST TO INCREASE TO 2 FT OR
SLIGHTLY HIGHER OVERNIGHT ALONG THE NJ AND DE ATLANTIC COAST AS NNE
WINDS INCREASE TO GALE FORCE ON THE W SIDE OF THE DEEPENING LOW
PRESSURE. ALSO THE WINDS MAY TEND TO PUSH WATER AGAINST THE S SIDE
OF DELAWARE BAY. THE MAIN THREAT WILL BE AROUND NEXT HIGH TIDE WHICH
WILL BE AROUND MIDNIGHT ALONG THE ATLANTIC COAST...AND A COUPLE OF
HOURS LATER ON THE DELAWARE BAY. BY THE NEXT HIGH TIDES WINDS WILL
HAVE SHIFTED TO OFFSHORE THUS ELIMINATING THE FLOODING THREAT.
