AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
453 PM EDT FRI JUN 1 2012
.SYNOPSIS...
LOW PRESSURE OVER THE NORTHERN GREAT LAKES WILL SEND A TRAILING COLD
FRONT THROUGH THE REGION DURING THE OVERNIGHT AND EARLY SATURDAY.
OVER THE WEEKEND, WEAK HIGH PRESSURE WILL BE FOUND OVER THE
SOUTHEASTERN STATES, AND LOW PRESSURE WILL LINGER NEAR THE NEW
ENGLAND COAST. WITH LOW PRESSURE REMAINING TO OUR NORTH INTO EARLY
NEXT WEEK, A FEW WEAK DISTURBANCES WILL SWING THROUGH OUR REGION. BY
MIDWEEK, HIGH PRESSURE TO OUR WEST MAY GRADUALLY SPREAD INTO THE
MID ATLANTIC.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
BASED ON A CONFERENCE CALL WITH SPC AT 445 PM...TORNADO WATCH 333
HAS BEEN EXTENDED JUST SLIGHTLY TO INCLUDE BERKS COUNTY. THERE IS
CONCERN THAT THE CELL CURRENTLY SHOWING STRONG ROTATION IN
LANCASTER COUNTY WILL HOLD TOGETHER AS IT MOVES NORTH. THIS CELL
IS EXPECTED TO MISS CHESTER COUNTY...WHICH IS WHY THAT COUNTY WAS
NOT INCLUDED IN THE TORNADO WATCH. THIS TORNADO WATCH EXPIRES AT 9
PM...SO ADDITIONAL DECISIONS WILL NEED TO BE MADE AS THE EVENING
WEARS ON.
WITH THE ADVANCING FRONTAL SYSTEM, THE MODEL WARM
FRONT MAKES IT AS FAR NORTH AS ABOUT RDG TO PHL TO JUST N OF ACY,
AND SO THE BEST INSTABILITY WOULD RESIDE FROM ABOUT THERE SOUTH IF
IT PLAYS OUT. ALTHOUGH SHEAR INCREASES AS ONE MOVES NORTH, THERE
IS GOOD SHEAR OVER THE ENTIRE FORECAST AREA. THAT PUTS THE
SOUTHERN AND PART OF THE WESTERN FORECAST AREA UNDER A THREAT OF
SEVERE WEATHER. WE NOTE THAT THE MODELS CONTINUE TO PUT OUR AREA
IN THE FAVORED QUAD OF AN UPPER JET TO OUR NORTHWEST (IN FACT,
THERE NOW APPEARS TO BE A COUPLET WITH OUR FORECAST AREA IN THE
FAVORED REGION). GOOD ISENTROPIC LIFT LEADS EARLY IN THE PERIOD AT
300K AS WE MOISTEN, AND THEN WITH THE ENERGY ROTATING AROUND THE
MID LEVEL VORTEX COMES GOOD MID LEVEL Q-VECTOR CONVERGENCE. THERE
IS VERY GOOD LOWER LEVEL FRONTOGENESIS, AND THERE IS SOLID
DIFFERENTIAL DIVERGENCE BETWEEN H925 AND H250. THE RATHER ROBUST
H850 TO H925 JET AXIS PASSES EAST DURING THE LATE EVENING, AND IT
CARRIES WITH IT VERY MOIST AIR (H850 DEW POINTS IN EXCESS OF 12
DEG C). AT MID LEVELS, H700 THETA E VALUES REACH 325K. PWATER
VALUES EXCEED 1.75 INCHES OVER OUR AREA, AND WE HAVE GOOD UPSLOPE
FLOW TO BOOT. THERE ARE ELEVATED CAPES PROGGED NORTH OF THE FRONT,
SO THE OLD FORECASTER'S RULE OF THUMB COMES INTO PLAY REGARDING
THE DOUBLING OF PWATER VALUES FOR MAXIMUM POINT RAINFALL. THIS HAS
MADE US PUT UP A FLASH FLOOD WATCH OVER AREAS WHERE THE THREE-HOUR
FFG VALUES ARE LESS THAN 2.5 INCHES AND/OR WHERE FFH VALUES ARE
SIMILARLY LOW. BASICALLY, THAT COVERS MOST OF THE AREA NEAR AND
NORTH OF THE I-95 CORRIDOR.
THE COLD FRONT IS FORECAST TO MOVE ACROSS THE AREA BY AROUND
DAYBREAK, AND WE EXPECT THAT TO PUT AN END TO RAINFALL AND ANY
THREAT OF SEVERE WEATHER. TEMPERATURES ARE CLOSE TO GUIDANCE AND
CONTINUITY.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
A DRY AND TOLERABLY BREEZY DAY IS FORECAST FOR SATURDAY. WE EXPECT A
FAIR AMOUNT OF CUMULUS TO DEVELOP, BUT THE MODELS INDICATE A
SUBSIDENCE CAP THAT SHOULD KEEP ANY SHOWERS FROM DEVELOPING.
TEMPERATURES AGAIN ARE CLOSE TO GUIDANCE AND CONTINUITY.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
OVERALL, UNSETTLED WEATHER IS ANTICIPATED TO START THE LONG TERM
PERIOD. MODEL GUIDANCE INDICATES A SURFACE LOW DEVELOPING NEAR THE
REGION DURING SATURDAY ALONG AN OCCLUDED FRONT. BY SATURDAY NIGHT,
THE LOW PRESSURE AND FRONT WILL BE SHIFTING TO OUR NORTH AND EAST.
MEANWHILE, THE PARENT LOW PRESSURE SYSTEM BACK OVER THE GREAT LAKES
WILL GRADUALLY CONSOLIDATE AND TRANSFER ITS ENERGY TO THE EAST, FROM
SUNDAY INTO EARLY NEXT WEEK. THIS MORE ENERGIZED LOW PRESSURE IS
PROGGED TO LINGER NEAR THE NEW ENGLAND COAST THROUGH ABOUT TUESDAY
OR WEDNESDAY, WITH A BLOCKING PATTERN IN PLACE. IN ADDITION TO THESE
LARGER SYNOPTIC FEATURES, A FEW SHORTWAVES ARE EXPECTED TO ROTATE
AROUND THIS OVERALL SYSTEM FROM SUNDAY THROUGH TUESDAY. HOWEVER, THE
EXACT TIMING AND STRENGTH OF THIS SHORTWAVE ENERGY CIRCLING THE
BROADER SYSTEM IS A BIT UNCERTAIN AT THIS TIME, WITH MODEL
DIFFERENCES BETWEEN THE GFS, EURO, AND OTHERS. ANY CONVECTIVE
ACTIVITY AT THIS TIME APPEARS TO BE MAINLY DIURNALLY DRIVEN, AND
MODEL SOUNDINGS INDICATE SUFFICIENT INSTABILITY, ESPECIALLY DURING
THE AFTERNOON TO EVENING TIMEFRAME. THUS, WE HAVE MAINTAINED THUNDER
AND THE HIGHER POPS SUNDAY THROUGH TUESDAY IN THE AFTERNOON TO EARLY
EVENING PERIODS, WITH LOWER POPS AT NIGHT. WITH MORE MODEL
CONSENSUS, WE WILL REFINE THE TIMING OF SHOWERS AND THUNDER DURING
THIS PERIOD.
BY MIDWEEK, THERE ARE SOME INDICATIONS THAT THIS PATTERN WILL
FINALLY CHANGE, WITH THE BROAD, CLOSED LOW PRESSURE MOVING AWAY AND
WEAKENING. HOWEVER, THE UPPER TROUGH MAY LINGER OVER THE AREA,
PROVIDING THE POSSIBILITY FOR SHOWERS/THUNDER DURING THE AFTERNOON
TO EVENING TIMEFRAME OF WEDNESDAY AND THURSDAY. MEANWHILE, SOME
MODEL GUIDANCE ALSO SHOWS SURFACE HIGH PRESSURE TO OUR WEST POSSIBLY
SPREADING EASTWARD INTO OUR REGION DURING THIS MIDWEEK PERIOD. BUT
WITH AN UPPER TROUGH STILL NEARBY, WE HAVE KEPT THE SLIGHT OR LOW
CHANCE POPS IN THE FORECAST FOR NOW.
WHAT IS RATHER APPARENT WITH THIS OVERALL SYNOPTIC PATTERN IS THAT
TEMPERATURES LOOK TO BE AROUND TO SLIGHTLY BELOW NORMAL THROUGH MUCH
OF THE LONG TERM PERIOD. WE USED CONTINUITY BLENDED WITH MOS OR HPC
GUIDANCE THROUGH THE PERIOD.
&&
.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
MVFR CEILINGS HAVE DEVELOPED OVER THE SOUTHERN TAF SITES, AND THEY
MAY BE STUBBORN EVEN OUTSIDE OF RAIN UNTIL THE COLD FRONT MOVES
THROUGH. OTHERWISE WE START THE TAF PERIOD WITH VFR CONDITIONS ON
EAST TO SOUTHEAST WINDS OF 10 TO 15 KT WITH GUSTS AT OR SOMEWHAT
ABOVE 20 KT, AND WE BRING THE DIRECTION AROUND TO SOLIDLY SOUTHEAST
AT THE TWO SOUTHERN TAF SITES DURING THE EVENING. WE ALSO BRING
CONDITIONS DOWN TO MVFR IN RAIN WITH OCCASIONAL IFR IN CONVECTION AT
ALL SITES. THE CONVECTION IS EXPECTED TO OCCUR MAINLY DURING THE
EVENING AND TO BE ELEVATED AT THE NORTHERN TAF SITES. THE SOUTHERN
TAF SITES WOULD EXPERIENCE STRONG WIND GUSTS IF STRONG SURFACE-BASED
CONVECTION AFFECTS THEM, BUT WE HAVE NOT FORECAST SUCH GUSTS WITH
THE 18Z PACKAGE. WE CARRY LLWS OVER THE TWO SOUTHEASTERN SITES FROM
MID EVENING INTO THE OVERNIGHT PERIOD. WE BRING CONDITIONS BACK TO
VFR FROM WEST TO EAST WITH THE COLD FRONTAL PASSAGE CENTERED AROUND
DAYBREAK. SATURDAY IS EXPECTED TO BE A DAY WITH WEST WINDS GUSTING
TO NEAR 20 KNOTS, VFR CUMULUS CLOUDS AND NO VISIBILITY RESTRICTIONS.
OUTLOOK...
SATURDAY NIGHT...VFR CONDITIONS WITH WESTERLY WINDS.
SUNDAY THROUGH WEDNESDAY...MAINLY VFR CONDITIONS EXPECTED THROUGH
THE PERIOD. SOME SUB-VFR PERIODS MAY OCCUR DURING SCATTERED
SHWRS/T-STORMS, MAINLY IN THE AFTERNOON TO EVENING TIMEFRAME.
&&
.MARINE...
ADVISORY WINDS ARE FORECAST WELL THROUGH MIDNIGHT. THEY ARE EXPECTED
TO BEGIN TO DIMINISH WITH THE COLD FRONTAL PASSAGE AROUND DAYBREAK,
BUT SEAS WILL TAKE SOME TIME TO SETTLE. A COMBINATION OF WINDS
FUNNELING UP THE BAY AND THE ELEVATED TOWERS TAPPING STRONGER WINDS
ABOVE THE MARINE LAYER MAY GENERATE GALE FORCE GUSTS AT SHIP JOHN
SHOAL AND BRANDYWINE SHOAL LIGHT, BUT WE ARE NOT GOING TO ISSUE A
GALE WARNING WITH THE AFTERNOON PACKAGE. ALTHOUGH ADVISORY WINDS
AREN'T EXPECTED ON SATURDAY, SEAS WILL TAKE TIME TO SETTLE BELOW THE
ADVISORY CRITERION.
OUTLOOK...
THROUGH THE LATTER PART OF THE FORECAST PERIOD, FROM SUNDAY THROUGH
EARLY NEXT WEEK, AN AREA OF LOW PRESSURE IS EXPECTED TO LINGER NEAR
THE NEW ENGLAND COAST. THE WINDS FOR OUR WATERS ARE ANTICIPATED TO
BE WEST TO NORTHWESTERLY INITIALLY AND THEN BECOME MORE NORTH TO
NORTHEASTERLY FROM MONDAY THROUGH WEDNESDAY. WITH THIS INCREASED
NORTH TO NORTHEAST FLOW AROUND THE LOW PRESSURE, IT'S PROBABLE THAT
SEAS FOR THE OCEAN WATERS WILL REACH AROUND 5 FEET AND THAT WIND
GUSTS COULD APPROACH 25 KNOTS. A SCA MAY BE NEEDED AT SOME POINT IN
THE EXTENDED PERIOD.
&&
.HYDROLOGY...
OUR REASONING FOR THE FLASH FLOOD WATCH IS GIVEN IN THE NEAR TERM
SECTION. WE DON'T EXPECT WIDESPREAD AMOUNTS ABOVE TWO TO TWO AND
ONE-HALF INCHES, BUT WE ARE CONCERNED THAT LOCATIONS THAT WOULD
FLOOD ON SUCH AMOUNTS ARE UNDER THE GUN TO SEE THEM.
&&
.TIDES/COASTAL FLOODING...
FOR THE EVENING HIGH TIDES ALONG THE ATLANTIC COAST, RARITAN BAY,
DELAWARE BAY AND THE TIDAL DELAWARE RIVER, NYOFS, DBOFS AND LOCAL
GUIDANCE EITHER BRING US CLOSE TO OR OVER THE MINOR TIDAL FLOODING
THRESHOLD, AND SO THE ADVISORY IS MAINTAINED. CBOFS IS BRINGING THE
MARYLAND EASTERN SHORE JUST ABOVE THE THRESHOLD FOR THE LATE
OVERNIGHT HIGH TIDE, BUT IT HAD BEEN RUNNING NEAR A HALF-FOOT ON THE
HIGH SIDE THROUGH THIS AFTERNOON. WE WILL MONITOR.
THE NEXT TIME FRAME OF CONCERN IS THE SUNDAY THROUGH TUESDAY HIGH
TIDE CYCLES. WITH THE FULL MOON EXPECTED ON MONDAY AND HIGHER
ASTRONOMICAL TIDES, SOME MINOR TIDAL FLOODING IS POSSIBLE
ESPECIALLY ALONG THE ATLANTIC COAST. THE ASTRONOMICAL HIGH TIDES
ARE ONLY RUNNING NEAR TWO-TENTHS BELOW MINOR TIDAL FLOODING
THRESHOLDS. THE FLOW IS OFFSHORE SO THAT MAY BE IN OUR FAVOR TO
START, BUT THE SURFACE WINDS MAY BECOME NORTHEASTERLY LATE MONDAY
AND TUESDAY.
&&
.RIP CURRENTS...
A WESTERLY FLOW IS EXPECTED TO DEVELOP ACROSS THE AREA AFTER A COLD
FRONT PASSES THROUGH EARLY SATURDAY. HOWEVER...RESIDUAL WAVE HEIGHTS
ALONG THE COAST MAY BE HIGH ENOUGH ON SATURDAY...ESPECIALLY IN THE
MORNING...FOR A MODERATE RISK OF RIP CURRENTS. CONDITIONS ARE
EXPECTED TO GRADUALLY IMPROVE AS THE DAY WEARS ON.
