What happened

The episode as NWS PHI wrote it up.

A wintry mix of sleet and freezing rain fell across most of Eastern Pennsylvania on the 1st. Sleet accumulations ranged from an inch or two in the Poconos to little if any toward Philadelphia. Ice accretions reached up to around half an inch in the Poconos. The wintry mix caused many accidents. In the Poconos, the accretion of ice on tree limbs and power lines caused scattered outages. Many schools north and west of Philadelphia were closed.

Precipitation began as a mixture of sleet and freezing rain between 5 a.m. and 7 a.m. EST across most of Eastern Pennsylvania. In the local Philadelphia area, precipitation started as plain rain. As warm air moved in northward at the surface, the freezing rain changed to plain rain in the Philadelphia northwest suburbs by 8 a.m. EST and in Berks County and the Lehigh Valley by 10 a.m. EST. Ice accretions averaged around one tenth of an inch in the Philadelphia northwest suburbs and two tenths of an inch in Berks County and the Lehigh Valley. In the Poconos, the cold air was never completely scoured and precipitation fell as freezing rain over the plateau region until it ended that evening.

In Monroe County layers of ice burdened branches and utility wires on February 1st, which caused power outages. Wires sagged or snapped under the weight of the ice, which resulted in some pole fires during the night of February 1st. A multi-vehicle crash at the start of the evening rush hour on February 1st forced the closure of Interstate 380 south between the Tobyhanna and Gouldsboro exits. Back roads were tricky as motorists had to dodge downed branches. In Lehigh County, a hit-and-run accident occurred in Washington Township as icy road conditions resulted from freezing rain. The crash happened at 6:00 PM EST as an unknown driver was traveling west on Main Street in Slatedale and lost control of the vehicle due to icy patches on the road surface. The vehicle crashed into a building on Main Street and the driver left the scene. In Berks County 911 dispatchers handled more than two dozen calls which reported accidents between 5:30 AM EST and 8:00 AM EST, due to freezing rain icing up roadways. Many of the accidents involved vehicles sliding off icy roads into ditches or trees. There were no reports of serious injuries. Westbound traffic on Interstate 78 was blocked for about three hours near the Krumsville exit about 7:00 AM EST by a crash which involved several tractor-trailers. Eastbound Interstate 78 traffic was not moving much, because one lane was blocked during much of the morning as a result of crashes. Also, Interstate 78 was closed between the Kutztown exit 35 (Route 737) and Lenhartsville exit 40 (Route 143) for several hours because a tractor-trailer accident. It reopened around 9:30 AM EST. A multi-vehicle crash occurred at about 5:45 AM EST at Pricetown Road and Route 73 in Ruscombmanor Township. In Muhlenberg Township, Crystal Road was closed near Spring Valley Road after a four vehicle, chain reaction, crash occurred at about 6:15 AM EST. Several other vehicles slid into walls or other cars on the road. No one was injured, but the road remained closed for more than two hours because tow trucks had a difficult time getting up the hill to remove the vehicles. In Brecknock Township, a sport utility vehicle slid off Maple Grove Road near Alleghenyville Road at about 6:40 AM EST, then turned onto its side after going down a 10-foot embankment. The driver was not hurt. In Chester County the State Police barracks at Embreeville reported 23 crashes in the area between 5:00 AM EST and 9:00 AM EST though most were minor.

The low pressure system that caused the wintry mix moved from Mississippi on the evening of January 31st northeast through the Ohio valley on the morning of the 1st. It reached western Pennsylvania during the afternoon of the 1st and passed near Scranton, Pennsylvania at 7 p.m. EST on the 1st before heading northeast into New York State. Preceding this low pressure system, a fairly strong high pressure system (around 1040 millibars) was able to leave a large pool of cold air in place at the surface across Eastern Pennsylvania that was difficult for the low pressure system to scour.

Area forecast discussion, Feb 1, 2:44 AM EST, 2 hours 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
244 AM EST FRI FEB 1 2008

.SYNOPSIS...
LOW PRESSURE, OVER THE TENNESSEE VALLEY THIS MORNING, WILL RACE
NORTHEAST AND REACH NEW YORK STATE THIS EVENING. THE ASSOCIATED
WARM FRONT WILL MOVE NORTH OF THE REGION THIS MORNING, AND THE
STRONG COLD FRONT WILL PUSH OFFSHORE TONIGHT. HIGH PRESSURE WILL
THEN BUILD OVER THE REGION SATURDAY THROUGH EARLY MONDAY. ANOTHER
WET SYSTEM WILL APPROACH FROM THE WEST MONDAY NIGHT.

&&

.NEAR TERM /THROUGH TONIGHT/...
TODAY IS GOING TO FEATURE EVERYTHING FROM SNOW/SLEET/FREEZING
RAIN/STRONG WINDS/POSSIBLY SVR TSTMS/SOME STREET-SMALL STREAM
FLOODING/...LOCUST COME LATER.

HIGH PRESSURE IS RETREATING TO THE NORTH AS THE BIG STORM TAKES
SHAPE OVER THE TENNESSEE VALLEY. THE STORM WILL REACH THE OHIO
VALLEY THIS AFTERNOON SPREADING PRECIPITATION ACROSS THE ENTIRE
REGION. TEMPERATURES THIS MORNING ARE IN THE UPPER 20S TO LOWER
30S MOST SPOTS. WE ARE EXPECTING TO SEE A RAPID CHANGEOVER TO RAIN
DURING THE LATE MORNING AND AFTERNOON BUT ALSO THERE WILL BE SOME
ICE ACCUMULATING NORTHWEST TO NORTH FROM THE DELAWARE VALLEY.
LATEST SOUNDING DATA UNCHANGED FROM LAST RUN WITH THE GREATEST
THREAT IN THE NORTHERN THREE ZONES. RAPID 80H WARMING WILL TAKE
PLACE THIS MORNING SO SOME AREAS MAY NOT GET THE DURATION,
HOWEVER, THE PRECIPITATION IS EXPECTED TO COME IN HEAVY WHICH WILL
OFFSET THE DURATION. A QUICK .25 INCH OF ICE IS POSSIBLE IN THE
NORTHERN ZONES AND .10 OF AN INCH IN THE LEHIGH VALLEY. ELSEWHERE
.05 TO .10 OF AN INCH OF ICE BEFORE THE CHANGE OVER.

THERE WILL BE A STRONG BELT OF WINDS JUST ABOVE THE SURFACE AHEAD OF
THE LOW, AND WITH, AND BEHIND THE FRONT. SITUATION TODAY MAY NOT
REACH WIND CRITERIA BUT IT WILL BE WINDY NONETHELESS. MORE
IMPORTANTLY, CONVECTION IS GOING TO PLAY A MAJOR ROLE IN
TRANSPORTING SOME OF THE STRONGER WINDS DOWN TO THE SURFACE. SURFACE
TEMPERATURES WILL REACH INTO THE LOW TO MID 50S IN THE THUNDERSTORM
THREAT AREA.

SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON INTO THE EARLY
EVENING FOR THE AREA EXTENDING SOUTH FROM PHILADELPHIA. IT IS
POSSIBLE THAT SEVERE THUNDERSTORM WARNINGS MAY BE NEEDED IN THOSE
AREAS.

THE PRECIPITATION WILL BE TAPERING OFF FROM THE SOUTHWEST TO
NORTHEAST DURING THE EVENING HOURS AND END ALL-TOGETHER BY
DAYBREAK SATURDAY. THE RAIN WILL END AS SNOW SHOWERS NORTHERN
ZONES.

TEMPERATURES OVERNIGHT UNDER 30 DEGREES FROM THE LEHIGH VALLEY
NORTH AND 30 TO 35 SOUTHERN AREAS.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
THE LOW TRACKS TO MAINE BY SATURDAY MORNING WITH DIMINISHING WINDS
ACROSS THE MID ATLANTIC STATES. TEMPERATURES REMAINING MILD ON
SATURDAY FOLLOWING THE FRONT AND DROPPING IN THE 20S MOST AREAS.
HIGH PRESSURE WILL BUILD OVER THE REGION INTO SUNDAY BUT AN UPPER
LEVEL SHORT WAVE MOVES THROUGH WITH AN INCREASE IN CLOUDS BUT NO
PRECIPITATION. HIGHS ON SUNDAY REMAINING MILD FOR EARLY FEBRUARY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
UNLIKE YESTERDAY AT THIS TIME, THERE IS SOMEWHAT BETTER MODEL
AGREEMENT IN THE LONG TERM, AND THE AGREEMENT HAS MOVED THE GFS INTO
THE POSITION AS THE MODEL TOWARD WHICH TO LEAN.

WE STILL START IN A PATTERN WITH A MID LEVEL TROF WELL TO THE WEST,
BUT NOW THERE IS SOME AGREEMENT THAT RIDGING OVER THE EAST WILL
CATCH US FOR THE BEGINNING OF THE WORK WEEK. THAT RIDGING SHOULD BE
PAST US BY TUESDAY, ALLOWING THE WESTERN TROF TO ADVANCE EAST WITH
AN ATTENDANT SURFACE LOW PRESSURE SYSTEM, COMPLETE WITH A LEADING
WARM FRONT AND A TRAILING COLD FRONT.

IT STILL LOOKS LIKE THE SURFACE REFLECTION LOW PRESSURE SYSTEM WILL
PASS WELL TO OUR WEST WITH THE SURFACE WARM FRONT TRYING TO MAKE
PROGRESS THROUGH OUR REGION MONDAY NIGHT OR TUESDAY, WHILE THE COLD
FRONT NOW LOOKS TO CROSS THE REGION TUESDAY NIGHT OR EARLY
WEDNESDAY. WE, OF COURSE, FACE THE POSSIBILITY OF SOME TRAPPED COLD
AIR LEADING TO A PERIOD OF SLEET OR FREEZING RAIN IN THE MONDAY
NIGHT TO EARLY TUESDAY TIME FRAME, ESPECIALLY NORTHWEST. HOWEVER,
THE RETREATING SURFACE HIGH DOES NOT LOOK THAT STRONG OR COLD, NOR
IS IT WELL-ENTRENCHED. FOR NOW, WELL STAY WITH THE SIMPLE TYPES OF
PRECIPITATION AND SEE IF/HOW SUBSEQUENT RUNS CHANGE THE SCENARIO.

THE GFS HAS NOW PICKED UP ON THE OLD ECMWF IMPULSE ALONG THE
TRAILING COLD FRONT, ALTHOUGH IT IS NOT THAT STRONG. THE ECMWF HAS
NOW DOWNPLAYED SAID IMPULSE. WE ARE GOING WITH A FAIRLY SLOW COLD
FRONTAL PASSAGE GIVEN THE MID LEVEL PATTERN OF A POSITIVE TILT TROF
AND THE FRONTAL IMPULSE, BUT THE AIR MASS BEHIND THE FRONT IS NOT
VERY COLD AND THIS DOES NOT APPEAR TO CAUSE ANY MAJOR WINTER WEATHER
CONCERNS AT THIS TIME. THE END OF LONG TERM APPEARS DRY.

&&

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
THE VFR CONDITIONS ACROSS THE AREA EARLY THIS MORNING WILL QUICKLY
DETERIORATE BY SUNUP WITH IFR CONDITIONS EXPECTED FOR MUCH OF THE
DAY. THERE WILL BE PERIODS WHEN CONDITIONS MAY IMPROVE TO MVFR OR
MAYBE EVEN VFR FOR AWHILE, BUT THE UN-PREDICTABILITY OF ANY
IMPROVEMENTS PRECLUDED ME FROM INCLUDING THEM IN THE TAFS.
PRECIPITATION WILL BE MAINLY RAIN OVER THE DELAWARE VALLEY AND SRN
NJ TAF SITES BUT A TEMPO GROUP FOR PL FOR A FEW HOURS AFTER 12Z WAS
RETAINED FROM THE PREVIOUS TAFS. ACROSS KRDG AND KABE A PERIOD OF
FZRA AND PL IS EXPECTED THIS MORNING BEFORE CHANGING TO RA THIS
AFTERNOON. CB GROUP INCLUDED FOR THE AFTERNOON WITH A CHC OF THUNDER
INDICATED IN STAT GUIDANCE.

LLWS WAS INCLUDED FOR A FEW SITES IN THE 00Z TAFS, AND I HAVE CHOSEN
TO EXPAND THE LLWS TO ALL SITES SINCE THE LLWS CRITERIA IS CLOSE AT
ALL AREAS AND THE E WIND NEAR THE SFC WILL SWITCH AROUND TO S OR SE
AROUND 5O TO 60 KT AT 925 MB AFTER 18Z.

CONDITIONS WILL IMPROVE AFTER 02Z TO 04Z AFTER A COLD FRONT CROSSES
THE TAF SITES. SCT TO CLR CONDITIONS WILL BE INCLUDED IN THE 12Z
TAFS FOR EARLY SATURDAY MORNING.

EXTENDED OUTLOOK...FINE WEATHER EXPECTED SATURDAY THROUGH SUNDAY
NIGHT. LOWER CONDITIONS WITH RAIN MAY ARRIVE LATER MONDAY.

.MARINE...
WINDS AND SEAS ARE IN THE PROCESS OF BUILDING ON THE WATERS ATTM,
AND SCA CONDITIONS WILL BUILD INTO A GALE THIS MORNING ACROSS THE
WATERS. THE CURRENT GALE FLAGS WILL REMAIN AS IS WITH THE EXPIRATION
TIME OF 06Z STILL LOOKING OK AS WELL. ALTHOUGH THE GALE GOES INTO
EFFECT AT 6AM IT MAY NOT BE UNTIL LATER THIS MORNING UNTIL THE GALES
GUSTS BECOME FREQUENT. ONCE THE FRONT CROSSES THE WATERS THIS
EVENING, ANOTHER PERIOD OF FREQUENT GALE GUSTS ARE EXPECTED.
CONDITIONS WILL IMPROVE AFTER MIDNIGHT WITH CONDITIONS SETTLING BACK
TO SCA LATER TONIGHT. THE NEXT SHIFT CAN CHANGE THE ENDING TIME
ACROSS THE WATERS IF NEEDED.

OUTLOOK...BETTER WEATHER ACROSS THE WATERS SATURDAY THROUGH TUESDAY,
THEN SCA OR GALE CONDITIONS POSSIBLE LATER TUESDAY NIGHT INTO WED AS
ANOTHER LOW MOVES TO THE WEST.

&&

.HYDROLOGY...
THE CHANGEOVER IS ANOTHER MATTER. QPF AMOUNTS FROM THIS MORNING
THROUGH THE LATE EVENING HOURS COULD BE 1.5 TO 2.0 INCHES IN SOME
AREAS AND THAT IS LIKELY TO POSE A THREAT ON THE HIGHWAYS THIS
AFTERNOON AS PONDING OCCURS, AND WE TURN ATTENTION TO THE POTENTIAL
FOR SMALL STREAM FLOODING. MARFC WORKED WITH 1.75 INCHES AND SEVERAL
STREAMS WENT OVER FLOOD STAGE.

WITH THE 1 TO 2 INCHES OF RAIN POSSIBLE, AREAS UP NORTH WHERE THE
GROUND IS PROBABLY MORE FROZEN WOULD BE MORE SUSCEPTIBLE TO RAPID
RUNOFF. ALTHOUGH WIDESPREAD FLOODING IS NOT EXPECTED, A FEW OF
OUR QUICKER RESPONDING CREEKS WILL NEED TO BE WATCHED. WE WILL
CONTINUE TO MONITOR THIS, HOWEVER ATTM NO HEADLINES BUT WILL
MAINTAIN A MENTION IN THE HAZARDOUS WEATHER OUTLOOK FOR MOST
AREAS.
