What happened

The episode as NWS PHI wrote it up.

A line of severe thunderstorms caused wind damage across the northern half of New Castle County. Several trees and wires were knocked down with the greatest concentration of wind and lightning damage in Hockessin (Mill Creek Hundred) and Middletown. About 2,800 homes and businesses lost power in the county. All power was restored by 1 p.m. EDT on the 7th. In Hockessin, downed trees were removed from three roadways and one home suffered minor damage when a tree fell onto it.

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
230 PM EDT MON JUN 6 2005

.OVERVIEW...
UNSEASONABLY WARM AND HUMID WEATHER WILL OCR THRUT MOST OF THIS FCST
PERIOD. IF ONE BELIEVES THE LATEST (00Z) ECMWF ITS ALSO BEYOND THE
CUR END OF OUR FCST PKG. H5 RDG EXPECTED TO REMAIN TOUGH WITH ONLY
SLGT RELIEF BEHIND CFP IN THE MIDDLE OF THIS WEEK. RETURN FLOW
AROUND THE H5 RDG WILL INCR CHCS FOR PCPN. LOCN OF RDG WILL PLAY
INTO THE FCST SO GENERAL BELIEF IS THAT THERE WILL BE A NW (HIER) TO
SE (LWR) GRAD OF POPS. PWATS STILL EXPECTED TO EXCEED 2 INCHES BY
THE WEEKEND. CFPS ARE NOT EXPECTED BEYOND TMRW AS THEY SHLD DISPT N
OF THE PA/NJ BORDER.

IN THE SHORT TERM...THE GFS H5 INIT WAS BETTER WITH A NOD TO THE NAM
FOR ITS H8 STRUCTURE. NEITHER MDL INIT THE SHRT WV THAT WAS THERE OR
DVLPD WITH MCS ACRS NCNTRL PA AND IF ANYTHING THEY ARE A COUPLE OF
HRS TOO SLOW. THIS WILL BE TAKEN INTO ACCOUNT WITH EXPECTED
CONVECTION LATER TDY. NOT TOO MANY DAYS WITH CAPES GT 3000J AND LI
LT -10 W ARND FORTUNATE FOR US THAT THE WIND FIELD IS NOT AS
ACCOMODATING. AFT CFP WE ARE EXPECTING A COUPLE OF LESS HUMID BUT
NOT NECESSARILY THAT MUCH COOLER DAYS.

&&

.SHORT TERM (TONIGHT THROUGH WEDNESDAY)...
TNGT...3000J LI TO -11...ENUF SAID WE WILL CONT ENHANCED WORDING IN
THE ZONES. WE WILL INCLUDE ALL FACETS OF PHENOMENA AS THE TSRAS
UPSTREAM HAVE BEEN PROLIFIC LTGNG PRODUCERS ALG WITH DAMAGING WINDS
AND LARGE HAIL. WE WILL END PCPN A BIT FASTER THAN THE MDLS HAVE
BECAUSE THEY SEEM TO BE BEHIND THE CURVE. GUID MINS ARE CLOSE AND
WON/T BE DABBLED.

FOR TMRW THE FCSTD SHRT WV IS NOW EXPECTED TO RMN N OF OUR CWA WITH
A REL SHALLOW LYR OF MSTR. NAM FCST SOUNDGS ARE SHOWING A CAP DVLPG
BY THE AFTN AND DON/T BLV THERE WILL BE ENUF TIME IN THE MRNG FOR
TSRAS TO POP. THE GFS SHOWING A BIT MORE PTNL BUT SINCE THERE IS A
NARROW WINDOW OF OPPORTUNITY BTWN THE TWO...DO NOT WANT TO FLIP-FLOP
CUR FCST AND LET THE MIDNIGHT SHIFT REACCESS. EVEN IF TSRAS WERE TO
OCR AREAL CVRG WOULD PBLY BE WDLY SCTD. WITH RESPECT TO TEMPS, THE
NAM IS SOMEWHAT WRMR THAN THE GFS AND OVERALL THE MAX TEMPS THE LAST
COUPLE OF DAYS HAVE FALLEN BTWN. WE WILL CONT THIS FCST TREND WHICH
WILL RESULT IN LITTLE ADJUSTMENT TO CUR TEMPS. WHL THE NAM BUFKIT
SOUNDGS HAVE LWRD TDS INTO THE UPR 50S THEIR MOS GUID IS RMNG CLOSE
TO 70(?). GIVEN THAT UPSTREAM DEWPTS IN OH ARE IN THE 60S WE WILL
SIDE WITH THE BTWN GFS MOS DEWS. WITH AFTN MIXING FCST DEWS MAY
STILL BE TOO HIGH. ERGO HEAT INDICES SHLD COME CLOSE TO MATCHING MAX
TEMPS TMRW AND NO ADTNL HEAT RELATED ADVYS WILL BE ISUSED.

A SLGTLY MORE COMFORTABLE SLEEPING NGT TUE NGT WITH DRIER AIR AND
LIGHT WINDS TO HELP RADIATE TEMPS IN NON URBAN LOCNS. GFS MOS LOOKS
BETTER GIVEN THE WRLY FLOW AND UPSTREAM DEWPTS.

KIND OF A HINT OF A SECONDARY CFP WED WITH THE GFS. NAM BUFKIT
SOUNDGS STILL SHOWING PRETTY MUCH A CAPPED ENVIRON AND CDFNT SHLD
DISPT AS IT TRIES TO COME ACRS. THUS DRY FCST WILL BE MAINTAINED.
BIG DIFS BTWN THE NAM AND GFS H8 TEMP FCSTS. THE ECMWF IS A COMP
BTWN THE TWO MDLS AND WILL BE FOLLOWED. THUS WE WILL SPLIT THE DIF
BTWN THE MOS DATASETS. ACTUALLY NGM MOS SEEMS TO HAVE BEEN DOING THE
BEST OF THE GUID DATASETS THE LAST COUPLE OF DAYS.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...
GENERAL TREND WILL BE TWD WRMR AND MORE HUMID WX THRUT THE FCST
PERIOD. NO CFP EXPECTED AS CDFNT LATE FRI EXPECTED TO RMN N OF OUR
CWA AND WAFFLE AROUND NEW ENGLAND FOR A DAY OR TWO. CLOSER PROX TO
THIS FNT WILL BE THE GREATER FOCUS FOR PCPN CHCS AS PWATS GT 1.5
WILL BE ARRIVING FROM LARGE MOISTURE POOL IN THE SERN U.S. IF RDG
RETORGRADES FAR ENUF TO OUR W...IT MIGHT CAP OUR PCPN CHCS. FOR NOW
IT APRS DIURNAL CHCS FRI THRU MON IS THE BEST WAY TO GO WITH THE
GREATEST CHCS IN OUR NWRN ZNS. GIVEN PWATS AND REL WEAK FLOW
ALF...THERE WILL BE HVY DOWNPOURS. NEXT CFP NOT SLATED UNTIL AFTER
OUR CUR DAY-TO-DAY FCSTS END.

&&
