Astronomical Low Tide in Pennsylvania, February 20 to 21, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
612 AM EST FRI FEB 20 2015

.SYNOPSIS...
HIGH PRESSURE WILL MOVE EAST FROM THE OHIO VALLEY TO THE EAST
COAST TODAY. A LOW PRESSURE SYSTEM WILL TRACK FROM THE SOUTHERN
PLAINS NORTHEASTWARD INTO THE REGION SATURDAY AND BRING A COLD
FRONT THROUGH THE REGION ON SUNDAY. HIGH PRESSURE WILL BUILD
SOUTHEASTWARD BEHIND THE FRONTAL BOUNDARY EARLY NEXT WEEK. THIS
WILL BE FOLLOWED BY LOW PRESSURE SYSTEMS, ONE COMING UP THE EAST
COAST AND THE OTHER FROM THE GREAT LAKES ON WEDNESDAY. ANOTHER
AREA OF HIGH PRESSURE WILL BUILD INTO THE REGION BY THURSDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
6 AM UPDATE TO ADD A CLIMATE SECTION TO PUT THE CURRENT COLD INTO
CONTEXT...

OVERNIGHT WATER VAPOR SATELLITE IMAGERY SHOWS A PIECE OF ENERGY
SPLIT OFF FROM THE POLAR VORTEX OVER NORTHERN NEW ENGLAND. THIS
SETUP HAS DRAWN THE CORE OF ARCTIC AIRMASS DIRECTLY INTO THE
NORTHERN MID-ATLANTIC REGION EARLY THIS MORNING. THERE IS STILL A
RELATIVELY TIGHT PRESSURE GRADIENT ACROSS THE AREA, RESULTING IN A
CONTINUATION OF A BRISK W-NW WINDS THROUGHOUT THE NIGHT. WINDS
HAVE EVEN STRENGTHENED A BIT OVERNIGHT IN CONCERT WITH A PRESSURE
SURGE. THE WINDS HAVE PREVENTED TEMPS FROM PLUMMETING AFTER DARK,
BUT THEY ARE HELPING TO PRODUCE BITTERLY COLD WIND CHILLS BETWEEN
10 BELOW AND 20 BELOW ZERO ACROSS MOST OF THE FORECAST AREA. THE
REPORTED WIND CHILL AT MT POCONOS WAS AS LOW AS 29 BELOW ZERO. THE
WIND CHILL WARNING FOR THE POCONOS AND FAR NW NJ AND WIND CHILL
ADVISORIES FOR THE REST OF THE CWA ARE VERIFYING, SO NO CHANGES
TO THE HEADLINES ARE NEEDED.

THE UPPER TROUGH ASSOCIATED WITH THE POLAR VORTEX WILL LIFT
NORTHEASTWARD TODAY INTO EASTERN CANADA. AT THE SURFACE, A 1032
MB HIGH THAT IS CENTERED OVER KY EARLY THIS MORNING WILL BUILD
EASTWARD INTO THE MID ATLANTIC. W-NW WINDS WILL GRADUALLY RELAX
THROUGHOUT THE DAY AS A RESULT OF THE WEAKENING PRESSURE
GRADIENT.

WEIGHTED THE MAX TEMP FORECAST MORE IN LINE WITH THE NON-STATISTICAL
OUTPUT FROM THE HRRR/NCEP WRF-ARW. THIS WARMER GUIDANCE VERIFIED
WELL YESTERDAY WHILE THE MAV/MET EXHIBITED A COOL BIAS. MAXIMUM
SOLAR HEATING, INCREASING LARGE-SCALE SUBSIDENCE, AND A
DOWNSLOPING COMPONENT TO THE FLOW OFF THE MOUNTAINS WILL
CONTRIBUTE TO WARMING THE COLUMN. NONETHELESS, HIGHS WILL ONLY BE
IN THE TEENS, WHICH IS AN IMPRESSIVE 25-30F BELOW NORMAL.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
THE CENTER OF THE SURFACE HIGH IS FORECAST TO BUILD EASTWARD TOWARD
THE MID-ATLANTIC COAST TONIGHT. EXPECT WINDS TO BECOME LIGHT IN
THE EVENING WHILE SKIES WILL BE MOSTLY CLEAR. THIS SETUP WILL
ALLOW TEMPS TO DROP QUICKLY AFTER SUNSET. WENT BELOW GUIDANCE FOR
MIN TEMPS TONIGHT IN THIS FAVORABLE RADIATIONAL COOLING
SETUP, ESPECIALLY AFTER FACTORING THE FEW INCHES OF SNOW ON THE
GROUND IN MOST LOCATIONS. SUB-ZERO MIN TEMPS ARE FORECAST FOR THE
VALLEYS IN NE PA, NW NJ AND THE PINE BARRENS WHILE THE REMAINDER
OF THE AREA SHOULD BOTTOM OUT IN THE SINGLE DIGITS. THE DROP IN
TEMPS MAY SLOW DOWN OVERNIGHT AS MID AND HI CLOUDS OVERSPREAD THE
AREA AHEAD OF THE NEXT STORM SYSTEM.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
SATURDAY THROUGH SUNDAY NIGHT:

OVERALL IN THIS PERIOD THERE IS GOOD MODEL AND ENSEMBLE AGREEMENT
THAT OUR REGION WILL IN BETWEEN TWO HIGH PRESSURE SYSTEMS. ONE OF
THE HIGH PRESSURE SYSTEMS WILL BE DIVING INTO THE PLAINS, THE OTHER
WILL BE OFFSHORE. THESE WILL ALLOW FOR A STORM TO TRACK FROM THE
SOUTHERN PLAINS INTO NEW ENGLAND IN THIS PERIOD.

CLOUDS WILL BE ON THE INCREASE AHEAD OF A WARM FRONTAL BOUNDARY
SATURDAY WITH LOW PRESSURE TRACKING INTO THE LOWER OHIO VALLEY.
TEMPERATURES WILL GRADUALLY WARM INTO THE 20'S AND 30'S THROUGHOUT
THE DAY. OVERRUNNING MOISTURE WILL LEAD TO THE DEVELOPMENT OF
PRECIPITATION SATURDAY AFTERNOON. THERMAL PROFILES SUGGEST
PRECIPITATION SHOULD START AS SNOW. BY SATURDAY NIGHT, TEMPERATURES
WILL CONTINUE TO RISE AS OVERRUNNING MOISTURE ALONG THE WARM FRONT
LEADS TO THE DEVELOPMENT OF MORE PRECIPITATION AND CHANGING
P TYPES. IT IS ENCOURAGING TO SEE IN BUFKIT ANALYSIS OF
THE NAM AND GFS THAT A PRETTY SEAMLESS TRANSITION FROM SNOW TO RAIN
OCCURS. HOWEVER, NOT FULLY CONVINCED THAT LOW LEVEL COLD DOESN'T
HANG ON LONGER PARTICULARLY NW OF PHL AND INTO NORTHERN NJ. SO HAVE
EXPRESSED A MIX OF SNOW/ICE IN THE CURRENT FORECAST BEFORE THE
CHANGE TO RAIN. QPF FORECAST IS MAINLY DERIVED FROM THE SREF AND THE
WPC FORECAST. IT SHOULD BE NOTED THAT THE RGEM AND NAM 00Z MODEL
RUNS SHOW A THUMP OF SNOWFALL LATE SATURDAY AFTERNOON ALONG
INTERSTATE 95 FROM PHL SW. THIS MAY PROVIDE SEVERAL INCHES OF SNOW
IN A SHORT TIME. ON THE OTHER HAND, THE SREF AND ECMWF ARE SLOWER
AND AS A RESULT WARMER. THIS FORECAST TAKES BOTH OF THESE OUTCOMES
INTO ACCOUNT WITH SOME REAMING UNCERTAINTY.

BY SUNDAY, MODELS HAVE TRENDED FASTER ENDING PRECIPITATION ON SUNDAY
LEAVING US WITH A CHANCE OF SHOWERS THROUGH THE DAY, ICE MIX
POCONOS. EVEN WITH THAT SAID, SOME MELTING OF THE SNOWPACK AND RIVER
ICE COULD OCCUR WITH TEMPERATURES ABOVE FREEZING. BOTH OF THESE MAY
CONTRIBUTE TO SOME HYDRO ISSUES. STAYED CLOSE TO MAV/MET THROUGHOUT
MOST PERIODS PERHAPS A LITTLE WARMER SATURDAY NIGHT AND SUNDAY TO
ACCOUNT FOR THE WARMER SREF AND ECMWF.

MONDAY AND MONDAY NIGHT: YET ANOTHER POTENT BLAST OF COLD AIR COMES
IN. NOT EXPECTING MUCH IN TERMS OF TEMPERATURE RISES, NON-DIURNAL
TEMPERATURE TREND POSSIBLE. 925 MB TEMPS WILL BE AROUND -15C,
UNDERCUT ENSEMBLE GUIDANCE A LITTLE. OTHERWISE DRY AND COLD. WIND
CHILLS MAY GO BELOW ZERO AGAIN. POCONOS COULD REACH -20.

TUESDAY AND WEDNESDAY: STAYED CLOSE TO THE ENSEMBLE GUIDANCE FOR
MOST WEATHER ELEMENTS. THE GFS/GEFS AND ECMWF/ECMWF ENSEMBLE MEAN
ARE SPLIT ON IF ANOTHER LOW PRESSURE CAN COME THE COAST. ECMWF IS
THE MOST AGGRESSIVE BUT IS BACKING OFF, AS HAVE THE UKMET AND CMC.
WILL CONTINUE LOW CHANCE POP FOR NOW.

THURSDAY: CONTINUED COLD BUT DRY WITH ANOTHER ARCTIC HIGH PRESSURE
SYSTEM, UNDERCUT ENSEMBLE GUIDANCE AGAIN WITH TEMPERATURES IN THIS
PERIOD WITH 925 MB TEMPS MODELED AROUND -15C.

&&

.TIDES/COASTAL FLOODING...
THE LOW WATER ADVISORY FOR TODAY WAS EXTENDED THROUGH TONIGHT FOR
THE DELAWARE BAY AND THE ATLANTIC COASTAL WATERS. BLOWOUT TIDES WERE
OCCURRING OVERNIGHT AND ARE EXPECTED THROUGH THE NEXT COUPLE OF HIGH
TIDE CYCLES. CANNOT RULE OUT THE POSSIBILITY OF BLOWOUT TIDES
CONTINUING INTO SATURDAY MORNING ALTHOUGH NEGATIVE ANOMALIES SHOULD
BE WEAKENING IN RESPONSE TO THE LIGHT WINDS.

LOW WATER ADVISORY IS CONTAINED IN THE MWW PRODUCT. AN SPS IS IN
EFFECT FOR ASSOCIATED AREAS ALONG THE TIDAL DELAWARE RIVER.

&&

.CLIMATE...
THE ONLY DAILY MIN TEMP RECORD THAT WAS SET YESTERDAY (2/19) WAS AT
GEORGETOWN, DE. THE LOW OF 10F BROKE THE OLD RECORD OF 11F (1993).

CURRENT TEMPS AS OF 6 AM HAVE ALREADY SET NEW DAILY RECORD MIN
TEMPS FOR 2/20 AT ILG AND TTN; AND ARE WITHIN A FEW DEGREES OF THE
RECORD AT ALL OTHER CLIMATE SITES EXCEPT MPO.

THE CURRENT TEMP OF 3F AT PHL IS THE COLDEST TEMP FOR PHILADELPHIA
SINCE 20 JAN 1994 WHEN A LOW OF 1F WAS RECORDED. BEFORE TODAY,
THE LAST OCCURRENCE OF A MIN TEMP OF 3F OR LOWER IN THE MONTH OF
FEBRUARY FOR PHILADELPHIA WAS 5 FEB 1996. THE LAST OCCURRENCE WITH
A MIN TEMP OF 2F OR LOWER WAS 20 FEB 1979. THE DAYS OF 20 FEB 1979
AND 24 FEB 1889 ARE THE ONLY DATES ON RECORD THAT HAD A MIN TEMP
OF 3F OR LOWER THIS LATE IN THE SEASON.

EVEN SATURDAY MAY HAVE RECORD COLD AFTER MIDNIGHT BEFORE TEMPS
START RISING AHEAD OF THE NEXT ARCTIC COLD FRONT DURING THE
MORNING.

THOSE RECORDS LISTED BELOW... (POR = PERIOD OF RECORD BEGINS)
