Damaging Wind in Maryland, August 29, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
458 PM EDT TUE AUG 29 2006

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
HIGH CAPES TO THE SOUTH OF THE STATIONARY FRONT AND THE
CONSIDERABLE SHEAR, IN PART DUE TO THE PROXIMITY OF THE BOUNDARY,
ARE RESULTING IN SOME STRONG ROTATING CELLS AND SOME VERY HEAVY
DOWNPOURS LATE THIS AFTERNOON. SURFACE REFLECTION OF THE NOT
TERRIBLY ROBUST, BUT ROBUST ENOUGH, IMPULSE WILL CROSS THE
SOUTHERN PART OF THE AREA LATE THIS EVENING AND THEN MOVE OUT TO
SEA. HOWEVER, WE REMAIN DOWNSTREAM OF A MID LEVEL LOW AND THE
UPPER JET DOES NOT MOVE THROUGH OUR AREA TOMORROW. HENCE, MOST
PLACES RETAIN CHANCE POPS BUT WE DO NOT CARRY AND CONVECTION. THE
UPPER JET GRADUALLY MOVES FAR ENOUGH SOUTH TO FORECAST DRY WEATHER
FROM LATE WED NIGHT THROUGH THURSDAY NIGHT NORTH AND CENTRAL, BUT
ENERGY MOVING OUT OF THAT PERSISTENT MID LEVEL LOW TO OUR WEST AND
A NOT TOO DISTANT SURFACE BOUNDARY WILL KEEP SRN ZONES IN CHANCE
POPS THROUGH THURSDAY NIGHT.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
WE HAVE STAYED CLOSE TO THE COOPERATIVE EFFORT BETWEEN TPC AND HPC
REGARDING ERNESTO, WHICH FOR NOW IS NOT FORECAST TO REACH HURRICANE
STRENGTH, BUT WHICH MIGHT DO SO FOR 12 TO 24 HRS IF IT TRACKS AS
FORECAST OUT TO SEA BRIEFLY ON THURSDAY MORNING AFTER MOVING ACROSS
FLORIDA. THE SYSTEM IS FORECAST TO MOVE TO OUR LATITUDE SOMETIME
LATE FRIDAY NIGHT, BUT BY THE TIME IT REACHES THAT FAR NORTH THE
TWO-THIRDS PROBABILITY CONE PUTS IT ANYPLACE FROM LEXINGTON, KY TO
JUST OFF THE CENTRAL DELMARVA. THE POINT FORECAST AT THAT TIME HAS
IT MOVING INTO WV NEAR ELKINS. HPC AND TPC HAD BEEN GIVING SOME
WEIGHT TO THE 00Z GFS, WHICH STILL HAD ERNESTO PUSHING NORTH
AGAINST FAIRLY STRONG HIGH PRESSURE OVER SERN CANADA, AND THAT
MAKES SOME INCREASE IN WINDS A DECENT POSSIBILITY. THE WORST CASE
SCENARIO WOULD INCLUDE HEAVY RAIN, STRONG WINDS, BEACH EROSION AND
TIDAL FLOODING, WHILE THE BEST CASE SCENARIO WOULD INCLUDE LITTLE
MORE THAN A GOOD BREEZE. THIS IS SAID TO EMPHASIZE THE UNCERTAINTY
INVOLVED IN FORECASTING A TROPICAL SYSTEM BEYOND 72 HOURS. PLEASE
FOLLOW SUBSEQUENT FORECASTS. FOR NOW, WE ARE ISSUING A ESF FOR THE
POSSIBILITY OF HEAVY RAIN BEGINNING FRIDAY.

AFTER ERNESTO, THERE IS NOT GREAT CONTINUITY ON THE MID LEVEL LOW
MOVING UP INTO THE GREAT LAKES, BUT THE SYSTEM IS STILL THERE ON THE
VARIOUS PROGS AND SO THE FORECAST STAYS UNSETTLED.

&&

.AVIATION...
A WARM FRONT FROM A LOW IN CENTRAL PA TO THE MOUTH OF THE DELAWARE
BAY HAS BEEN MOVING VERY SLOWLY EAST NORTHEAST TODAY. NORTH OF THE
FRONT, WEVE HAD ST OR SC CIGS ALL DAY. SOUTH OF THE FRONT, THE
CLOUDS HAVE BROKEN AND THE SUN HAS MADE AN APPEARANCE. THE LOW WAS
NEAR SEG THIS AFTERNOON AND WILL MOVE OR REDEVELOP TO THE SOUTHEAST
TONIGHT. THE CLOUDS WILL CONTINUE TO TRY TO ERODE FOR THE NEXT FEW
HOURS, BUT AFTER SUNSET, THE SC/ST WILL BEGIN TO SPREAD BACK S AS
THE LOW MOVES OFF TO THE E AND SE AND WINDS SWING AROUND TO THE NE.
SHOWERS AND TSTMS THIS EVENING WILL LOWER CIGS AND VSBYS TO IFR/LIFR.
WITH PLENTY OF LOW LEVEL MOISTURE, WE CAN EXPECT LOW CLOUDS AND FOG
OVERNIGHT WITH IFR CONDS. EXPECT VSBYS TO IMPROVE AFTER SUNRISE
TOMORROW. ST CIGS WILL RISE TO SC BY MID OR LATE MORNING.

&&

.MARINE...
LOW PRESSURE WILL MOVE ACROSS THE MARINE AREA TONIGHT. A LARGE
HIGH PRESSURE SYSTEM WILL PUSH DOWN FROM THE NORTH WEDNESDAY THROUGH
THURSDAY. OUR NEXT WEATHER PROBLEM WILL THEN BE ERNESTO AS IT
TRACKS NORTH. THE MILLION DOLLAR QUESTION, AS ALWAYS, IS THE TRACK
OF THE STORM. IT APPEARS THAT IT WILL MOVE INLAND AND STAY TO OUR
WEST. BUT THE MODELS CERTAINLY DONT AGREE ON JUST HOW FAR WEST.
REGARDLESS OF THE ULTIMATE TRACK, ERNESTO WILL MOVE INTO THE STRONG
HIGH PRESSURE SYSTEM TO OUR NORTH. THIS WILL TIGHTEN THE PRESSURE
GRADIENT AND GIVE US NE TO E WINDS, WHICH, IN TURN, WILL CAUSE
WINDS AND SEAS TO INCREASE LATER IN THE WEEK, ESPECIALLY THURSDAY
INTO THE WEEKEND. WITH THE HOLIDAY WEEKEND APPROACHING, MARINERS AND
ANYONE ELSE VENTURING TO THE AREA WATERS SHOULD KEEP UP TO DATE ON
THE LATEST ADVISORIES ON ERNESTO ISSUED BY THE NATIONAL HURRICANE
CENTER.
