Area forecast discussion, Apr 20, 10:02 PM EDT, 1 hour before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1002 PM EDT MON APR 20 2015
.SYNOPSIS...
A WARM FRONT JUST NORTHWEST OF INTERSTATE 95 WILL MERGE WITH AN
EASTWARD MOVING COLD FRONT AND PUSH OUT TO SEA BY MORNING. SEVERAL
REINFORCING COLD FRONTS WILL MOVE SOUTHEAST THROUGH THE MID ATLANTIC
STATES TUESDAY, WEDNESDAY AND THURSDAY AFTERNOONS. LOW PRESSURE
WILL CROSS TO THE SOUTH OF THE AREA SATURDAY INTO SATURDAY NIGHT.
HIGH PRESSURE WILL GRADUALLY BUILD IN FROM THE WEST THROUGH THE
WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
10 PM: ADDED A SHORT PERIOD OF COASTAL FLOOD ADVISORY FOR NE NJ
VCNTY SANDY HOOK WHICH HAS EXCEEDED THE ADVISORY THRESHOLD.
I PROBABLY DONT HAVE ENOUGH FOG GOING IN THE FCST N OF I78 FOR THE
NEXT SEVERAL HOURS.
930 PM: PER SPC AND COLLAB HAVE EXTENDED THE TOR WATCH 90 AND SVR
WATCH 92 CONTINUES AS POSTED. SO FAR, NOT MUCH HAS HAPPENED IN OUR
CWA BUT IT ONLY TAKES ONE BIG STORM TO MAKE LIFE VERY DIFFICULT
AND SO WE WANT EVERYONE PREPARED. THE FOCUS OF THE REMAINING
ACTIVITY SHOULD BE IN EASTERN PA AND CENTRAL/NNJ NEAR THE QSTRY
FRONT WHERE CONVERGENCE IS FOCUSED.
VERY UNSTABLE WARM SECTOR -2 TO 4 SBLI AS OF 01Z/21 WITH PLENTY
OF 0-6KM BULK SHEAR, THE NEARBY QSTRY FRONT AND A SFC LOW NEAR
KMDT, MEAGER 3 HR PRES FALL OF 1MB VCNTY PA AND LIKELIHOOD OF
OVERALL CFP BY 07Z-08Z, SUGGEST WE STILL NEED TO BE ALERT FOR
EVENTUAL BOWING OF UPSTREAM SEGMENTS AND STRONG WESTERLY WIND
GUSTS ARRIVING HERE. THE 2215Z STORM AT KRDG DELIVER 38KT. IT WAS
A SMALL SUPERCELL.
UNCERTAINTY ON HOW FAR EAST SVR BUT UNSTABLE AIRMASS AND
INCREASING ACTIVITY UPSTREAM.
QSTNRY FRONT JUST NW OF I95. STRONGEST STORMS ANTICIPATED ALONG
OR EAST OF THAT LATE THIS EVENING.
AFTER WHATEVER GUSTY WSHIFT LATE THIS EVENING, THEN THE WIND
BRIEFLY BACKS TO SW AHEAD OF THE PRIMARY CFP AND THERE MAY BE ANOTHER
SHOWER OR TSTM AROUND 06Z THEN VARIABLE CLOUDS AND A STEADY WEST
WIND TOWARD DAWN.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
DEEP LOW PRESSURE REMAIN ACROSS CANADA WHILE HIGH PRESSURE BUILDS
OVER THE SE STATES. RATHER STRONG PRESSURE GRADIENT WILL CREATE
MODERATE/GUSTY WINDS TUESDAY. MOSTLY FAIR WEATHER IS EXPECTED.
TEMPERATURES WILL BE SEASONABLY COOL WITH HIGHS IN THE LOW/MID 60S
MOST AREAS. WEST WINDS 15 MPH WITH GUSTS 25-30 MPH.
&&
.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
A PERSISTENT UPPER LEVEL TROUGH WILL SPIN OVER THE GREAT LAKES AREA
WITH A GRADUAL PUSH TO EAST THROUGH THE WEEK, SETTLING OVER EXTREME
NORTHEASTERN UNITED STATES AND SPINNING ACROSS EASTERN CANADA
THROUGH THE WEEKEND. SEVERAL SHORTWAVES EMBEDDED IN THE UPPER LEVEL
FLOW WILL ROTATE THROUGH OUR AREA AND WE WILL SEE SHOWERS CROSS
PARTS OF THE REGION THROUGH THE WEEK.
A COLD FRONT WILL PUSH DOWN THROUGH THE REGION WEDNESDAY INTO
WEDNESDAY NIGHT, WITH A CHANCE FOR SOME SHOWERS ACROSS THE AREA.
COLDER AIR LOCATED ALONG AND BEHIND THE FRONT MAY ALLOW FOR SOME
SNOW FLAKES TO FALL ACROSS THE HIGHER TERRAIN OF THE SOUTHERN
POCONOS.
A SECOND COLD FRONT IS FORECAST TO ARRIVE BY THURSDAY EVENING BUT IT
APPEARS TO LACK MUCH MOISTURE. THEREFORE, ONLY A FEW LIGHT SHOWERS
ACROSS THE NORTHWESTERN AREAS MAY OCCUR AS THE MOISTURE LESSENS AS
IT PUSHES THROUGH THE REGION.
THE UPPER LOW FINALLY MOVES EASTWARD BUT THE CYCLONIC FLOW WILL
REMAIN ACROSS THE REGION INTO THE WEEKEND WITH A CHANCE FOR SHOWERS
CONTINUING.
THE MODELS ARE SHOWING THAT A LOW PRESSURE SYSTEM WILL CROSS TO THE
SOUTH OF THE REGION DURING THE WEEKEND. JUST HOW FAR NORTH THE
SYSTEM GETS WILL DICTATE WHETHER OR NOT WE SEE SHOWERS PUSH
NORTHWARD INTO OUR SOUTHERN AREAS. WE HAVE INCLUDED JUST A SLIGHT
CHANCE FOR SOME SHOWERS FOR SATURDAY AND SATURDAY NIGHT ACROSS THE
SOUTHERN PORTION OF THE FORECAST AREA.
HIGH PRESSURE WILL THEN BUILD IN FROM THE WEST FOR SUNDAY AND MONDAY
WITH A DRY PERIOD EXPECTED ACROSS OUR REGION.
