Damaging Wind in Maryland, August 18, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
400 PM EDT WED AUG 18 2004

.SHORT TERM/LONG TERM...
LEE SIDE SURFACE TROF AND A MID-LEVEL S/W HELPING TO KICK OFF
SCATTERED THUNDERSTORMS, MAINLY SRN CWA. STRONGER ONSHORE FLOW TODAY
ALSO HELPING TO REINFORCE SOME HIGHER DEWPOINTS AND INCREASE
SURFACE CONVERGENCE. DIURNAL HEATING CONTRIBUTION ALSO IN THE MIX
AND BECAUSE OF THIS WE SHOULD SEE THINGS SIMMER DOWN THIS EVENING.
BUT, THE GFS DEPICTS ANOTHER WEAKER S/W TRACKING ACROSS SERN PA AND
THE NORTHERN DELMARVA TONIGHT. WELL KEEP SMALL POPS HERE.

WITH IT BEING NO DRYER TONIGHT COMPARED TO LAST NIGHT, FOG IS
PROBABLE. WE COULD SEE SOME MORE CLOUDS THOUGH AS SAT PIX SHOWS
UPSTREAM MID AND HIGH MOISTURE WORKING THIS WAY. THIS COULD PLAY
TRICKS WITH ANY FOG THAT DOES DEVELOP.

ANOTHER S/W IS FORECAST TO TRACK MORE TO THE NORTH TOMORROW.
NORTHERN ZONES ARE IN SLIGHT RISK(DAY TWO). WILL HIT POPS HARDER
HERE. THINGS SHOULD BECOME MORE TAME BY TOMORROW EVENING(FOR MOST).
BOTH THE GFS AND ETA HAVE SOME WARM FRONT SIGNATURES MOVING THROUGH
THE CWA ON FRIDAY. AS THIS FEATURE APPROACHES LATE THURSDAY NIGHT IT
COULD SET OFF ANOTHER ROUND OF PRECIPITATION, MORE SO ACROSS THE
NORTH, AS IT INTERACTS WITH ANOTHER POSSIBLE S/W.

SATURDAY LOOKS LIKE THE WORSE DAY OF THE WEEKEND AS A COLD FRONT AND
ITS ASSOCIATED SHOWERS AND THUNDERSTORMS MOVE THROUGH. WE COULD SEE
A BIT OF RESIDUAL MOISTURE ON SUNDAY MORNING BEFORE SURFACE HIGH
PRESSURE BUILDS.

AFTER A BIT OF HEAT ON FRIDAY, THE AREA WILL ONCE AGAIN SEE AT OR
BELOW NORMAL TEMPS FOR THE BEGINNING OF NEXT WEEK.

.AVIATION...
CU FIELDS FINALLY DEVELOPING AS BAND OF CIRRUS MOVES
THRU AND CAP LIFTED. EXPECT TO SEE TSTMS DEVELOPING SOON OVER LEHIGH
VALLEY AND SOUTH OF THE SHIELD OVER NORTHEASTERN MD. SWOMCD CONTAINS
DETAILS ON TSTM OUTBREAK AND SEVERITY ACROSS THE CFA. LATER TONIGHT
SOME FOG TO FORM AND WE GET TO RECYCLE TODAYS WX FOR THU. HAZE LAYER
AROUND 085 FT WHICH MAY BE OBSCURING THE DEVELOPING CU.

.MARINE...
MWS HAS BEEN ISSUED FOR CLUSTER OF TSTMS OVER DEL BAY AND
SOUTHERN COASTAL WATERS. OTHERWISE...4 SEC 3 FTERS AND WW MODEL
CONSISTENT WITH 3-4 FT NEXT SEVERAL DAYS WITH BROAD SW FLOW, HOWEVER
LIKELY TO SEE SOME SEAS APPROACHING 5 FT IN 20-25 KT SW 80H FLOW THU
NIGHT. SSTS STILL HOLDING IN THE 70S FOR GOOD PART OF THE COAST
AND EVEN WARMER IN BACK BAYS. WARM WATERS ARE BREEDING GROUND FOR
THIS AFTN TSTMS.
