What forecasters said that day
The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this winter weather advisory went out at Jan 5, 10:08 AM EST, 5 hours 18 minutes earlier.
Area forecast discussion, Jan 5, 10:08 AM EST, 5 hours 18 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1008 AM EST MON JAN 5 2015
.SYNOPSIS...
ARCTIC HIGH PRESSURE BUILDS INTO THE AREA TODAY AND TONIGHT. A
SERIES OF CLIPPER SYSTEM IS EXPECTED TO PASS THROUGH THE AREA
TUESDAY AND WEDNESDAY. HIGH PRESSURE BUILDS BACK INTO THE AREA
THURSDAY. ANOTHER CLIPPER SYSTEM MAY MOVE THROUGH THURSDAY NIGHT
AND FRIDAY FOLLOWED BY THE RETURN OF HIGH PRESSURE FOR THE
WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE MORNING SFC ANALYSIS SHOWS 980MB LOW PRES OVER THE GULF OF ST
LAWRENCE AND 1042MB HIGH PRES OVER THE MID-MS VLY...WITH RESULTING
STG PRES GRAD OVER THE MID-ATLANTIC REGION. NW WINDS ARE GUSTING TO
THE UPPER 20S/LOWER 30S KT RANGE AND A LITTLE STRONGER OVER THE HIER
TERRAIN NW. MORNING SOUNDINGS SHOW THE AIR MASS WELL MIXED UP TO
ABOUT 800MB. THE ASSOCD STRONG LOW-LVL COLD ADVECTION WILL RESULT IN
A NON-DIURNAL SLOWLY FALLING TEMP TREND DURING THE DAY TODAY. STLT
IMAGERY SHOWS CLOUD STREAMERS COMING OFF LAKE ERIE AND ACROSS PA
INTO NJ...BUT ANY SNOW FALLING OUT OF THE CLOUDS IS NOT LIKELY TO
REACH THE GROUND DUE TO THE INCREASINGLY DRY AIR MASS. NO
SIGNIFICANT CHANGES WERE MADE TO THE CURRENT FORECAST.
PREVIOUS DISCUSSION BELOW...
THE ARCTIC COLD FRONT LIES WELL OFFSHORE AND WILL CONTINUE TO PUSH
EASTWARD THROUGHOUT THE DAY WHILE STRONG COLD AIR ADVECTION
CONTINUES BEHIND ITS DEPARTURE. THE COLDER AIRMASS IS ALSO MUCH
DRIER AS DEWPOINTS ARE FORECAST TO DIP INTO THE SINGLE DIGITS BY
LATER THIS EVENING IN MOST PLACES. FORECAST SOUNDINGS CONTINUE TO
SHOW DEEP LAYER NEARLY DRY-ADIABATIC MIXING, UPWARDS OF 800MB, TODAY
ALLOWING FOR GOOD DOWNWARD MOMENTUM TRANSFER OF 35 KNOTS OF WINDS.
DON'T EXPECT 100 PERCENT MIXING, AT LEAST NOT TO 800MB, BUT NUMEROUS
GUSTS CLOSE TO 35 MPH ARE QUITE POSSIBLE THROUGH THE AFTERNOON HOURS
BEFORE SOME DECREASE IS EXPECTED.
SOME OF THE HI-RES GUIDANCE IS TRYING TO SHOW A FEW LAKE EFFECT
STREAMERS PUSHING THROUGH THE REGION LATER THIS AFTERNOON. IN
PARTICULAR THE NMMB IS SHOWING A CONNECTION ALL THE WAY BACK TO
NORTH OF CLEVELAND, OH. FIGURING WITH THE DRYING AIRMASS AND A
STRONG WESTERLY DOWNSLOPING FLOW IT'S DOUBTFUL WE SEE MORE THAN
FLURRIES THIS AFTERNOON, AND MOST OF IT SHOULD BE CONFINED TO THE
NORTHERN ZONES. LAPSE RATES, AS STATED ABOVE, ARE VERY STEEP BUT MAY
NOT BE ENOUGH TO GET THESE PROJECTED STREAMERS TO PUSH DEEP ENOUGH
INTO OUR CWA AS THE TERRAIN TO OUR WEST COULD SHRED THEM APART
BEFORE REACHING US.
TEMPERATURES TODAY ARE PRETTY ODD IN THAT WE WILL NOT BE
EXPERIENCING A DIURNAL TREND...WE WILL CONTINUE TO FALL THROUGHOUT
THE DAY RATHER THAN WARM. CURRENTLY WE ARE SITTING IN THE LOW TO
MID-40S IN MOST PLACES AND EXPECT TO BE BELOW FREEZING NORTH AND
WEST OF THE CITY BY LATE MORNING...BY LATE AFTERNOON SOUTH AND EAST
OF THE CITY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
GUSTS SHOULD BECOMING TO AN END BY LATE EVENING AS HIGH PRESSURE
MOVES OVERHEAD LOWERING THE SUBSIDENCE INVERSION QUITE A BIT. WE
STILL SHOULD HAVE A DECENT LOW-LEVEL LAPSE RATE IN PLACE WITH A
TIGHTER THAN NORMAL PRESSURE GRADIENT SO DON'T EXPECT TO LOSE THE
WINDS COMPLETELY...SUSTAINED AROUND 5 TO 10 MPH TONIGHT.
INCREASING CLOUD COVER FROM THE WEST-SOUTHWEST AHEAD OF THE QUICK
MOVING CLIPPER SYSTEM EJECTING OUT OF THE OHIO VALLEY. THE TRACK
CURRENTLY LOOKS TO PASS RIGHT ALONG OR JUST SOUTH OF THE MASON DIXON
LINE BEGINNING LATE TONIGHT. SNOW SHOULD BEGIN TO OVERSPREAD FROM
THE WEST CLOSER TO DAYBREAK TOMORROW MORNING WHICH MAY AFFECT THE
START OF MORNING RUSH HOUR.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
THE MAIN WEATHER STORY IN THE LONG TERM WILL BE THE COLD THIS WEEK.
TEMPS WILL LIKELY STAY BELOW FREEZING THROUGH SATURDAY FOR A
MAJORITY OF THE AREA. THE HEART OF THE ARCTIC AIR THAT TAKES AIM
AT OUR REGION LATE WEDNESDAY AND THURSDAY WILL BE ON PAR WITH THE
COLD OUTBREAK THAT WE EXPERIENCED LAST YEAR IN LATE JANUARY.
A CLIPPER SYSTEM EMBEDDED IN THE POLAR JET STREAM IS FORECAST TO
TRACK FROM THE OHIO VALLEY TO THE MID ATLANTIC ON TUESDAY. THE DAY
SHIFT YESTERDAY NOTED A SOUTHWARD SHIFT IN THE MODEL GUIDANCE WITH
THE TRACK OF THE DISTURBANCE AND AXIS OF SNOWFALL. THERE HAS BEEN
BETTER RUN TO RUN CONSISTENCY WITH THE LATEST 00Z MODELS BUT THEY
STILL TRENDED A BIT SOUTHWARD COMPARED TO YESTERDAY'S GUIDANCE.
MODELS SIMULATE THE RELATIVELY GREATER ISENTROPIC LIFT AND
FRONTOGENETICAL FORCING WITH THIS SYSTEM TO PASS SOUTH OF
PENNSYLVANIA TURNPIKE AND I-195 TUESDAY MORNING, WHICH WAS USED AS
A PROXY TO DRAW THE HIGHEST POPS AND SNOWFALL AMOUNTS. HOWEVER,
ACCUMULATIONS WILL BE LIGHT SINCE THE LIFT APPEARS TO BE MODEST
AND MOSTLY CONFINED TO THE MID-LEVELS. ADDITIONALLY, THIS SYSTEM
WILL BE A FAST MOVER (ABOUT A 6 HOUR WINDOW FOR SNOW). THIS IS
LOOKING LIKE A 1-2 INCH EVENT EVEN WITH SNOW RATIOS BETWEEN 12:1
AND 15:1. WE MAY EVEN SEE LOCALLY HIGHER AMOUNTS TO 3 INCHES
ACROSS SOUTHEASTERN PA/SOUTHERN NJ/NORTHERN DELMARVA. THE SNOW IS
EXPECTED TO COINCIDE WITH THE MORNING RUSH, WHICH HEIGHTENS THE
POTENTIAL FOR ADVERSE IMPACTS ON TRAVEL ESPECIALLY SINCE TEMPS
WILL BE IN THE 20S AND SNOW WILL HAVE AN OPPORTUNITY TO ACCUMULATE
ON ROADWAYS. THE SNOW IS EXPECTED TO TAPER OFF DURING THE AFTERNOON
AND SHOULD BE JUST ABOUT OUT OF HERE BY THE EVENING RUSH.
ANOTHER ALBERTA CLIPPER IS FORECAST TO MOVE THROUGH THE REGION ON
WEDNESDAY. LIFT WITH THIS SYSTEM WILL BE MUCH WEAKER THAN ITS
PREDECESSOR AND MOISTURE LIKELY GETS SQUEEZED OUT BY THE MOUNTAINS
TO OUR WEST. NONETHELESS, SOME OF THESE SNOW SHOWERS AND FLURRIES
SHOULD MAKE IT INTO OUR AREA GIVEN THE STEEP LAPSE RATES UP TO 700
MB. LOCALIZED SNOWFALL ACCUMULATIONS WOULD GENERALLY BE UNDER AN
INCH ALTHOUGH HIGHER AMOUNTS ARE POSSIBLE IN THE POCONOS.
A BRISK NW WIND AND STRONG CAA IN THE WAKE OF WEDNESDAY'S CLIPPER
WILL PROVIDE A REINFORCING SHOT OF ARCTIC AIR. 850 MB TEMPS OF -24
TO -27C ARRIVE WEDNESDAY NIGHT. THE COLDEST NIGHT AND DAY IN ALMOST
A YEAR ARE EXPECTED FOR WEDNESDAY NIGHT AND THURSDAY. BELOW ZERO
WIND CHILLS ARE POSSIBLE FOR JUST ABOUT THE ENTIRE FORECAST AREA
EARLY THURSDAY. A WIND CHILL ADVISORY MAY BE NEEDED FOR THE POCONOS
AND FAR NORTHWEST NJ WHERE FORECAST WIND CHILLS ARE BETWEEN 10 AND
20 BELOW. THE LATEST MAX TEMP FORECAST FOR THURSDAY TRENDED SLIGHTLY
WARMER AS THE CORE OF THE COLD AIR IS NOW ANTICIPATED TO RETREAT
FASTER. HOWEVER, IT'S STILL SEVERAL DEGREES BELOW THE LATEST WPC
GUIDANCE.
WINDS BACK OUT OF THE SOUTHWEST AND AIRMASS MODERATES FURTHER
THURSDAY NIGHT AS THE CENTER OF THE ARCTIC HIGH SHIFTS OFF THE
SOUTHEAST COAST AND THE NEXT CLIPPER SYSTEM CROSSES THE GREAT LAKES.
REGARDLESS, IT WILL STILL BE COLD THURSDAY NIGHT EVEN FOR JANUARY
STANDARDS. THE BEST FORCING WILL RESIDE NORTH OF THE AREA. LOW
CHANCES OF SNOW SHOWERS CONTINUES TO BE ADVERTISED FOR NORTHEAST
PA/NORTHWEST NJ OVERNIGHT THURSDAY.
THE AFOREMENTIONED CLIPPER IS FORECAST TO MOVE THROUGH THE NORTHEAST
STATES ON FRIDAY WITH ARCTIC AIR WORKS BACK INTO THE AREA THOUGH
THIS AIRMASS WILL NOT BE QUITE AS COLD AS MIDWEEK'S. WINDS WILL BE
BREEZY AGAIN DURING THE DAY.
ANOTHER PIECE OF THE ARCTIC HIGH IS EXPECTED TO BUILD BACK INTO THE
FOR THE FIRST HALF OF THE WEEKEND. THE COLD WILL CONTINUE WITH TEMPS
ABOUT 10-15 BELOW NORMAL.
THERE IS SOME INDICATION THAT SOUTHERN STREAM ENERGY ORGANIZES OVER
THE SOUTHEAST STATES THIS WEEKEND. BOTH THE 00Z GFS AND ECMWF HINT
AT AN INVERTED TROUGH SHARPENING JUST OFF THE EAST COAST. DEPENDING
ON WHERE THE TROUGH AXIS DEVELOPS AND THE EVOLUTION OF THE UPPER
SHORTWAVE TROUGH TO OUR SOUTH, MIXED PRECIP MAY IMPACT PORTIONS OF
THE AREA LATE IN THE WEEKEND. THERE IS STILL A LOT OF UNCERTAINTY
THIS FAR OUT.
&&
.AVIATION /15Z MONDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

PEAKING THIS MORNING IN THE LOW-30 KNOT RANGE AND SUBSIDING INTO THE
MID-20 KNOT RANGE LATER THIS EVENING.
TONIGHT..VFR. GUSTS SHOULD DROP OFF LATE THIS EVENING LEAVING US
WITH 10 TO 12 KNOTS OF SUSTAINED WINDS THROUGH
MIDNIGHT...DECREASING A BIT FURTHER THEREAFTER. INCREASING CLOUD
COVER EXPECTED AHEAD OF THE NEXT QUICK MOVING LOW PRESSURE SYSTEM
ARRIVING BY LATER TUESDAY MORNING.
OUTLOOK...
TUESDAY...LIGHT SNOW EXPECTED TO OVERSPREAD THE TERMINALS TUESDAY
MORNING. IFR/LIFR VSBYS POSSIBLE IN HEAVIER SNOW. THE SNOW QUICKLY
EXITS THE AREA FROM SW TO NE IN THE AFTERNOON
TUESDAY NIGHT...VFR AND LIGHT WINDS.

THURSDAY AND THURSDAY NIGHT...WINDS RELAX THRUOUT THE DAY AND
BECOMING LIGHT AT NIGHT. VFR.
FRIDAY...WEST WINDS BECOME BREEZY AGAIN. VFR.
&&
.MARINE...
THE GALE WARNING FOR DELAWARE BAY HAS BEEN REPLACED WITH A SMALL
CRAFT WARNING AS OF 1000 AM. WINDS OVER THE BAY WILL CONTINUE TO
GUST UP TO THE 25-30KT RANGE THIS AFTERNOON BEFORE DIMINISHING
THIS EVENING.
PREVIOUS DISCUSSION BELOW...
TODAY...GALES EVERYWHERE THROUGH THE MORNING HOURS BEFORE SOME
SUBSIDING SHOULD OCCUR ON THE DELAWARE BAY...END TIME IS CURRENTLY
10AM THERE...6PM ON THE OCEAN FRONT.
TONIGHT...SCA GUSTS LIKELY THROUGH THE LATE EVENING HOURS BEFORE
FALLING BELOW CRITERIA. HIGH PRESSURE PASSING OVERHEAD TONIGHT SO
THE WINDS SHOULD SLACKEN QUITE A BIT AFTER MIDNIGHT.
OUTLOOK...
TUESDAY...NO HAZARDS EXPECTED ON THE WATERS
TUESDAY NIGHT...SOUTHWEST WINDS INCREASE. POTENTIAL FOR SCA
CONDITIONS LATE TUESDAY NIGHT.
WEDNESDAY AND WEDNESDAY NIGHT...WEST-NORTHWEST WINDS GUSTING 30-40
KT ARE EXPECTED. GALES ARE LIKELY, ESPECIALLY OVER THE COASTAL
WATERS.
THURSDAY AND THURSDAY NIGHT...GUSTY NORTHWEST WINDS WILL GRADUALLY
DIMINISH TO SMALL CRAFT ADVISORY CRITERIA. THERE MAY BE A BRIEF
PERIOD OF SUB SCA ADVISORY CONDITIONS BEFORE WINDS INCREASE AGAIN
LATER THURSDAY NIGHT.
FRIDAY...WEST WINDS BECOME GUSTY. SCA LIKELY ALTHOUGH THERE IS A
POTENTIAL FOR NEAR GALE-FORCE GUSTS.
&&
.TIDES/COASTAL FLOODING...
CURRENT TIDAL DEPARTURES ARE SHOWING ANYWHERE FROM A HALF TO THREE
QUARTERS OF A FOOT BELOW. IF OUR CURRENT DEPARTURES PERSIST, WHICH
LOOKS LIKELY GIVEN WE WILL HAVE THE SAME STRENGTH OFFSHORE FLOW THIS
AFTERNOON, WE SHOULD REMAIN OUT OF REACH OF BLOW-OUT TIDES. THAT
BEING SAID, TIDAL SURGE GUIDANCE CONTINUES TO INDICATE THAT WE GET
CLOSE TO BLOW-OUT CONDITIONS ALONG THE OCEANFRONT AND DELAWARE/
RARITAN BAYS SO WE WILL NEED TO CONTINUE TO MONITOR THE SITUATION.
ANOTHER FRONTAL PASSAGE COULD PRODUCE A SECOND ROUND OF BLOWOUT
TIDES WEDNESDAY AND THURSDAY.
