THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH

BKN BANDS OF STG-SVR TSTMS ARE FCST TO CONTINUE MOVING EWD TO ENEWD
AT 25-35 KT ACROSS COASTAL AREAS OF MD/DE/NJ/NY AND SRN NEW ENGLAND.
CONVECTIVE TRANSLATIONAL SPEEDS AND DEEP-LAYER SHEAR EACH SHOULD
INCREASE WITH NWD EXTENT IN STEP WITH RELATIVELY FASTER MID-UPPER

RATES AND GENERATE 1000-2000 J/KG MLCAPE. BUOYANCY WILL RESIDE ATOP
WELL-MIXED SUBCLOUD LAYER SUITABLE FOR MAINTAINING HAIL AND STG-SVR
DOWNDRAFTS TO SFC.

VIS IMAGERY INDICATES FORMERLY DENSE/SW-NE ALIGNED CLOUD PLUME OVER

DAY1SVR: Day 1 Convective Outlook

SWODY1
SPC AC 281952

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0252 PM CDT MON JUN 28 2010

VALID 282000Z - 291200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF SRN NEW
ENGLAND...THE CNTRL APPALACHIAN MTNS AND MID-ATLANTIC...

ONLY TWO CHANGES HAVE BEEN MADE FOR THE 20Z OUTLOOK. THE FIRST IS TO
TRIM THE SLIGHT RISK AREA ON THE WRN EDGE MAINLY IN WV WHERE
DESTABILIZATION IS WEAKER THAN AREAS TO THE EAST. FOR MORE DETAILS
CONCERNING THE SEVERE THREAT WITHIN THE SLIGHT RISK AREA...SEE MCD
1156. THE SECOND CHANGE IS TO TRIM THE WRN EDGE OF THE THUNDERLINE
AND LOW-END PROBABILITIES TO THE EAST IN THE GREAT LAKES AND OH
VALLEY WHERE THUNDERSTORM DEVELOPMENT APPEARS LESS LIKELY DUE TO A
COLD FRONT MOVING SEWD ACROSS THE REGION.

..BROYLES.. 06/28/2010

.PREV DISCUSSION... /ISSUED 1127 AM CDT MON JUN 28 2010/

...MID ATLANTIC TO SE NEW ENGLAND THIS AFTERNOON/EVENING...
A DEEP CLOSED LOW OVER JAMES BAY WILL CONTINUE TO MOVE SLOWLY SSEWD
WHILE EMBEDDED SPEED MAXIMA ROTATE EWD AROUND THE SRN PERIPHERY OF
THE LOW. A PRIMARY EMBEDDED SHORTWAVE TROUGH OVER LOWER MI AS OF
LATE MORNING WILL EJECT EWD/ENEWD OVER THE SAINT LAWRENCE VALLEY
THROUGH EARLY TONIGHT. THIS TROUGH WILL BE PRECEDED BY A REMNANT
MCV THAT WILL MOVE EWD FROM ERN OH/WRN PA TO SE NEW ENGLAND THIS
AFTERNOON. AT THE SURFACE...THE SYNOPTIC COLD FRONT IS NOW CROSSING
INDIANA/NW OH/SW ONTARIO. A BAND OF RELATIVELY THICK CLOUD COVER IS
LIMITING SURFACE HEATING/DESTABILIZATION IMMEDIATELY E OF THE COLD
FRONT...AND THIS SHOULD CONTINUE TO BE THE CASE THROUGH THE
AFTERNOON ACROSS MUCH OF WRN/CENTRAL PA AND NY. FARTHER SE FROM THE
THICKER CLOUDS...STRONG SURFACE HEATING IS UNDERWAY ALONG THE I-95
CORRIDOR. ONCE SURFACE TEMPERATURES WARM INTO THE LOW-MID
90S...CONVECTIVE INHIBITION SHOULD BE LARGELY REMOVED AND
THUNDERSTORM DEVELOPMENT IS EXPECTED BY EARLY AFTERNOON NEAR THE
PRE-FRONTAL TROUGH AND GRADIENT IN CLOUD COVER.

THE WARM SURFACE TEMPERATURES AND AFTERNOON BOUNDARY LAYER DEWPOINTS
IN THE UPPER 60S TO LOWER 70S WILL SUPPORT MODERATE INSTABILITY
/MLCAPE NEAR 1500 J PER KG/...WITH SURFACE TEMP-DEWPOINT SPREADS
APPROACHING 20-25 F. THOUGH SOME GRADUAL WEAKENING OF THE 35-50 KT
WSWLY FLOW IN THE 850-600 MB LAYER IS EXPECTED BY MID AFTERNOON...A
CORRESPONDING INCREASE IN FLOW ALOFT WILL MAINTAIN SUFFICIENT
VERTICAL SHEAR FOR ORGANIZED STORM CLUSTERS...AS WELL AS THE
POTENTIAL FOR BOWS AND EVEN SUPERCELLS ACROSS SE NEW ENGLAND GIVEN
THE PRESENCE OF MODERATE INSTABILITY. THE COMBINATION OF
FACTORS...INCLUDING RELATIVELY WARM TEMPERATURES ALOFT AND MODEST
MIDLEVEL LAPSE RATES...APPEARS SUPPORTIVE OF PRIMARILY A DAMAGING
WIND THREAT THIS AFTERNOON INTO THIS EVENING.

...OH/WRN PA AND NY THIS AFTERNOON...
THE SYNOPTIC COLD FRONT WILL PROVIDE A FOCUS FOR THUNDERSTORM
DEVELOPMENT...AS NOTED BY DEEPENING CUMULUS AND SMALL CB/S ALONG THE
BOUNDARY IN NW OH AS OF 16Z. HOWEVER...POOR MIDLEVEL LAPSE RATES
AND CLOUDS WILL LIMIT THE POTENTIAL FOR DESTABILIZATION...AND IT
APPEARS THAT MAINTAINING ONLY LOW DAMAGING WIND PROBABILITIES IS
APPROPRIATE FOR THIS UPDATE. REFER TO MESOSCALE DISCUSSIONS 1151
AND 1152 FOR ADDITIONAL INFORMATION.

...SRN APPALACHIANS TO CENTRAL/E TX THIS AFTERNOON...
A COLD FRONT WILL SAG SEWD ACROSS KY/TN/AR/SE OK THROUGH THE
AFTERNOON. STRONG SURFACE HEATING S OF THE FRONT WILL AGAIN
CONTRIBUTE TO MODERATE AFTERNOON INSTABILITY IN AN ENVIRONMENT OF
WEAK VERTICAL SHEAR AND BOUNDARY LAYER DEWPOINTS IN THE 70S.
THUS...PROFILES WILL BE FAVORABLE FOR PULSE-TYPE STORMS WITH THE
POTENTIAL FOR ISOLATED STRONG DOWNBURST WINDS ALONG THE FRONT...AS
WELL AS WITH THE OUTFLOW-ASSISTED SEA BREEZE ACROSS THE GULF COAST
AND THE HIGHER TERRAIN OF THE SRN APPALACHIANS THIS AFTERNOON.

SCATTERED TO NUMEROUS STORMS WILL LIKELY DEVELOP THE NEXT FEW HOURS
ACROSS SERN KY AND THE SRN PORTIONS OF THE APPALACHIAN MTNS. THE
STRONGER STORMS WILL BE CAPABLE OF SPORADIC POCKETS OF WIND DAMAGE
AS THEY MOVE EWD CROSSING THE CUMBERLAND GAP AND CREST OF THE HIGHER
TERRAIN. A WW IS POSSIBLE OVER THE ERN PORTIONS OF THE DISCUSSION
AREA.

MESOANALYSIS PLACES A WEAK LOW LEVEL CONFLUENT ZONE FROM NEAR BWG TO
JKL EWD INTO SRN WV AHEAD OF THE MAIN SYNOPTIC FRONT THAT IS LOCATED
ALONG THE OH RIVER. RADAR IMAGERY OVER THE PAST 30 MIN SHOWS
SCATTERED CONVECTION BLOSSOMING ALONG AND S OF THIS ZONE WHERE TEMPS
ARE CONTINUING TO WARM INTO THE 80S AND LOWER 90S--ACTING TO STEEPEN
LOW LEVEL LAPSE RATES. MODERATELY STRONG H85-H7 FLOW WILL SPREAD
EWD AWAY FROM THE REGION TOWARDS THE MID ATLANTIC AS AN UPPER LEVEL
TROUGH MOVES TOWARDS THE ST LAWRENCE VALLEY. BEFORE THIS OCCURS
STORMS WILL CONTINUE TO INTENSIFY THIS AFTERNOON INTO ONE OR MORE
SMALL MULTICELLULAR CLUSTERS. AND...CONDITIONS WILL BECOME MORE
FAVORABLE FOR DOWNWARD MOMENTUM TRANSPORT OF SOME MODESTLY STRONG

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE NRN
ROCKIES...

...NRN ROCKIES...
AN UPPER-LEVEL TROUGH WILL APPROACH THE PACIFIC NORTHWEST TUESDAY AS
AN UPPER-LEVEL RIDGE OVER THE NRN HIGH PLAINS MOVES SLOWLY EWD. A
SWLY 50 TO 65 KT MID-LEVEL JET IS FORECAST TO BE IN PLACE ACROSS THE
NRN ROCKIES WITH THIS FEATURE CREATING 40 TO 55 KT OF DEEP LAYER
SHEAR. IN ADDITION TO THE SHEAR...SFC DEWPOINTS IN THE LOWER
ELEVATIONS SHOULD BE AROUND 50 F WHICH WILL HELP TO CREATE MODERATE
INSTABILITY BY MID-AFTERNOON AS SFC TEMPS WARM. THE INSTABILITY AND
SHEAR COMBINATION SHOULD BE SUFFICIENT FOR SUPERCELLS THOUGH
CONVECTIVE COVERAGE MAY REMAIN SOMEWHAT ISOLATED DUE TO RELATIVELY
WEAK LARGE-SCALE ASCENT. THE GREATEST POTENTIAL FOR LARGE HAIL
SHOULD EXIST ACROSS NW MT AND NCNTRL ID WHERE THE MODELS SHOW STEEP
MID-LEVEL LAPSE RATES WITH THE GREATEST CONVECTIVE COVERAGE. AN
ISOLATED WIND DAMAGE POTENTIAL MAY ALSO EXIST ESPECIALLY DURING THE
LATE AFTERNOON WHEN ETA-KF FORECAST SOUNDINGS SHOW THE STEEPEST
LOW-LEVEL LAPSE RATES.

...GULF COAST STATES/CAROLINAS...
A COLD FRONT IS FORECAST TO MOVE SWD INTO THE NRN GULF COAST STATES
AND WRN CAROLINAS TUESDAY WITH SCATTERED THUNDERSTORMS DEVELOPING
ALONG AND SOUTH OF THE BOUNDARY BY AFTERNOON. ALTHOUGH THE WARM
SECTOR WILL BE VERY MOIST AND MODERATELY UNSTABLE WITH SFC DEWPOINTS
NEAR 70 F...ETA-KF FORECAST SOUNDINGS SHOW RELATIVELY WEAK VERTICAL
SHEAR PROFILES. THIS SHOULD BE THE LIMITING FACTOR FOR SEVERE STORM
DEVELOPMENT. HOWEVER...A FEW DAMAGING WIND GUSTS WILL BE POSSIBLE
DURING THE LATE AFTERNOON WHEN INSTABILITY WILL BE MAXIMIZED AND
LOW-LEVEL LAPSE RATES WILL BE QUITE STEEP.

...TX/LA COASTS...
THE NATIONAL HURRICANE CENTER IS FORECASTING TROPICAL STORM ALEX TO
STRENGTHEN INTO A HURRICANE AND TO MOVE INTO THE WRN GULF OF MEXICO
TUESDAY NIGHT. BY THEN...THE OUTER RAINBANDS ASSOCIATED WITH ALEX
COULD BE LOCATED ALONG THE IMMEDIATE TX AND LA COASTS IF THE CENTER
OF THE SYSTEM MOVES A BIT FASTER THAN FORECAST. IN THIS CASE...THE
MORE INTENSE CELLS EMBEDDED IN THE RAINBANDS COULD BE STRONG ENOUGH
FOR MARGINALLY SEVERE DAMAGING WIND GUSTS AND A BRIEF TORNADO.
HOWEVER...DUE TO THE SLOWER FORECAST MOTION...WILL NOT ADD ANY
PROBABILITIES ATTM.

SOUTHEAST PENNSYLVANIA
NORTHERN VIRGINIA
COASTAL WATERS

EFFECTIVE THIS MONDAY AFTERNOON AND EVENING FROM 110 PM UNTIL 800
PM EDT.

HAIL TO 1 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS TO 70
MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.

THE SEVERE THUNDERSTORM WATCH AREA IS APPROXIMATELY ALONG AND 60
STATUTE MILES EITHER SIDE OF A LINE FROM 55 MILES SOUTHWEST OF
WASHINGTON DISTRICT OF COLUM TO 30 MILES NORTHEAST OF TRENTON NEW

REMEMBER...A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE
FAVORABLE FOR SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY
DO PRODUCE TORNADOES.

DISCUSSION...SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP IN THE
NEXT COUPLE OF HOURS IMMEDIATELY E OF THE HIGH TERRAIN...ALONG A
DIFFERENTIAL HEATING BOUNDARY FROM NRN VA INTO SE PA. SURFACE
TEMPERATURES IN THE 90S TO THE E OF THE CLOUD BOUNDARY AND BOUNDARY
LAYER DEWPOINTS OF 68-72 F ARE CONTRIBUTING TO MODERATE
INSTABILITY...ALONG THE SRN FRINGE OF THE STRONGER MIDLEVEL
FLOW/SHEAR. THE MODERATE FLOW/INSTABILITY AND RELATIVELY DEEP
SURFACE MIXED LAYER WILL SUPPORT DAMAGING GUSTS WITH ORGANIZED
MULTICELL CLUSTERS...AND POTENTIALLY SOME EMBEDDED BOW/SUPERCELL
STRUCTURES THROUGH THE AFTERNOON/EVENING AS STORMS APPROACH THE
COAST.

PERSISTENT/THICK CLOUD DECK EVIDENT IN VIS IMAGERY. IN AND S OF
THIS ZONE -- ROUGHLY ALONG LINE FROM HGR-POU-PSM -- STG SFC HEATING
COMBINED WITH SFC DEW POINTS NEAR 70 F WILL BOOST MLCAPE INTO

...THERE IS A SLGT RISK OF SVR TSTMS THIS AFTERNOON/EVENING FROM THE

...MID ATLANTIC TO SE NEW ENGLAND THIS AFTERNOON/EVENING...
A DEEP CLOSED LOW OVER JAMES BAY WILL CONTINUE TO MOVE SLOWLY SSEWD
WHILE EMBEDDED SPEED MAXIMA ROTATE EWD AROUND THE SRN PERIPHERY OF
THE LOW. A PRIMARY EMBEDDED SHORTWAVE TROUGH OVER LOWER MI AS OF
LATE MORNING WILL EJECT EWD/ENEWD OVER THE SAINT LAWRENCE VALLEY
THROUGH EARLY TONIGHT. THIS TROUGH WILL BE PRECEDED BY A REMNANT
MCV THAT WILL MOVE EWD FROM ERN OH/WRN PA TO SE NEW ENGLAND THIS
AFTERNOON. AT THE SURFACE...THE SYNOPTIC COLD FRONT IS NOW CROSSING
INDIANA/NW OH/SW ONTARIO. A BAND OF RELATIVELY THICK CLOUD COVER IS
LIMITING SURFACE HEATING/DESTABILIZATION IMMEDIATELY E OF THE COLD
FRONT...AND THIS SHOULD CONTINUE TO BE THE CASE THROUGH THE
AFTERNOON ACROSS MUCH OF WRN/CENTRAL PA AND NY. FARTHER SE FROM THE
THICKER CLOUDS...STRONG SURFACE HEATING IS UNDERWAY ALONG THE I-95
CORRIDOR. ONCE SURFACE TEMPERATURES WARM INTO THE LOW-MID
90S...CONVECTIVE INHIBITION SHOULD BE LARGELY REMOVED AND
THUNDERSTORM DEVELOPMENT IS EXPECTED BY EARLY AFTERNOON NEAR THE
PRE-FRONTAL TROUGH AND GRADIENT IN CLOUD COVER.

THE WARM SURFACE TEMPERATURES AND AFTERNOON BOUNDARY LAYER DEWPOINTS
IN THE UPPER 60S TO LOWER 70S WILL SUPPORT MODERATE INSTABILITY
/MLCAPE NEAR 1500 J PER KG/...WITH SURFACE TEMP-DEWPOINT SPREADS
APPROACHING 20-25 F. THOUGH SOME GRADUAL WEAKENING OF THE 35-50 KT
WSWLY FLOW IN THE 850-600 MB LAYER IS EXPECTED BY MID AFTERNOON...A
CORRESPONDING INCREASE IN FLOW ALOFT WILL MAINTAIN SUFFICIENT
VERTICAL SHEAR FOR ORGANIZED STORM CLUSTERS...AS WELL AS THE
POTENTIAL FOR BOWS AND EVEN SUPERCELLS ACROSS SE NEW ENGLAND GIVEN
THE PRESENCE OF MODERATE INSTABILITY. THE COMBINATION OF
FACTORS...INCLUDING RELATIVELY WARM TEMPERATURES ALOFT AND MODEST
MIDLEVEL LAPSE RATES...APPEARS SUPPORTIVE OF PRIMARILY A DAMAGING
WIND THREAT THIS AFTERNOON INTO THIS EVENING.

...OH/WRN PA AND NY THIS AFTERNOON...
THE SYNOPTIC COLD FRONT WILL PROVIDE A FOCUS FOR THUNDERSTORM
DEVELOPMENT...AS NOTED BY DEEPENING CUMULUS AND SMALL CB/S ALONG THE
BOUNDARY IN NW OH AS OF 16Z. HOWEVER...POOR MIDLEVEL LAPSE RATES
AND CLOUDS WILL LIMIT THE POTENTIAL FOR DESTABILIZATION...AND IT
APPEARS THAT MAINTAINING ONLY LOW DAMAGING WIND PROBABILITIES IS
APPROPRIATE FOR THIS UPDATE. REFER TO MESOSCALE DISCUSSIONS 1151
AND 1152 FOR ADDITIONAL INFORMATION.

...SRN APPALACHIANS TO CENTRAL/E TX THIS AFTERNOON...
A COLD FRONT WILL SAG SEWD ACROSS KY/TN/AR/SE OK THROUGH THE
AFTERNOON. STRONG SURFACE HEATING S OF THE FRONT WILL AGAIN
CONTRIBUTE TO MODERATE AFTERNOON INSTABILITY IN AN ENVIRONMENT OF
WEAK VERTICAL SHEAR AND BOUNDARY LAYER DEWPOINTS IN THE 70S.
THUS...PROFILES WILL BE FAVORABLE FOR PULSE-TYPE STORMS WITH THE
POTENTIAL FOR ISOLATED STRONG DOWNBURST WINDS ALONG THE FRONT...AS
WELL AS WITH THE OUTFLOW-ASSISTED SEA BREEZE ACROSS THE GULF COAST
AND THE HIGHER TERRAIN OF THE SRN APPALACHIANS THIS AFTERNOON.

...MID ATLANTIC TO SE NEW ENGLAND THIS AFTERNOON/EVENING...
A DEEP CLOSED LOW OVER JAMES BAY WILL CONTINUE TO MOVE SLOWLY SSEWD
WHILE EMBEDDED SPEED MAXIMA ROTATE EWD AROUND THE SRN PERIPHERY OF

LATE MORNING WILL EJECT EWD/ENEWD OVER THE SAINT LAWRENCE VALLEY

MCV THAT WILL MOVE EWD FROM ERN OH/WRN PA TO SE NEW ENGLAND THIS
AFTERNOON. AT THE SURFACE...THE SYNOPTIC COLD FRONT IS NOW CROSSING
INDIANA/NW OH/SW ONTARIO. A BAND OF RELATIVELY THICK CLOUD COVER IS
LIMITING SURFACE HEATING/DESTABILIZATION IMMEDIATELY E OF THE COLD

THUNDERSTORM DEVELOPMENT IS EXPECTED BY EARLY AFTERNOON NEAR THE
PRE-FRONTAL TROUGH AND GRADIENT IN CLOUD COVER.

THE WARM SURFACE TEMPERATURES AND AFTERNOON BOUNDARY LAYER DEWPOINTS
IN THE UPPER 60S TO LOWER 70S WILL SUPPORT MODERATE INSTABILITY

POTENTIAL FOR BOWS AND EVEN SUPERCELLS ACROSS SE NEW ENGLAND GIVEN
THE PRESENCE OF MODERATE INSTABILITY. THE COMBINATION OF

CONTRIBUTE TO MODERATE AFTERNOON INSTABILITY IN AN ENVIRONMENT OF

AREAS AFFECTED...PORTIONS NWRN PA...CENTRAL/WRN NY...ERN LE.

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 281605Z - 281700Z

ISOLATED TSTMS DEVELOPING INVOF LAKE BREEZES...INITIALLY OVER
PORTIONS NWRN PA AND FAR WRN NY...MAY INCREASE IN COVERAGE/INTENSITY
AND POSE RISK OF SVR HAIL/GUSTS.

VIS IMAGERY SHOWS RATHER DENSE/PERSISTENT CLOUD SHIELD ACROSS MUCH
OF WRN/NRN PA AND NERN OH...HOWEVER SUFFICIENT DIABATIC HEATING IS
OCCURRING TO ITS N...AND UNDER ITS THINNER NRN FRINGES...TO REDUCE
MLCINH TO ALMOST NOTHING. MODIFIED RAOBS AND RUC SOUNDINGS SUGGEST
MLCAPE RISING INTO 500-1000 J/KG RANGE THROUGH MIDDAY...AS SFC
HEATING AND UPPER 60S TO LOW 70S F SFC DEW POINTS COUNTERACT MODEST
LAPSE RATES ALOFT IN GENERATING ADDITIONAL BUOYANCY. ALTHOUGH
MODIFIED RUC SOUNDINGS AND VWP SUGGEST ONLY ABOUT 30-35 KT EFFECTIVE
BULK SHEAR MAGNITUDE ACROSS THIS AREA ATTM...TWO EFFECTS MAY
INCREASE SHEAR DURING NEXT FEW HOURS...
1. TIGHTENING HEIGHT GRADIENT ALOFT RELATED TO APCHG SHORTWAVE
TROUGH...NOW EVIDENT IN MOISTURE CHANNEL IMAGERY OVER NRN ONT AND
LOWER MI...AND
2. LOCALIZED BACKING OF BOUNDARY LAYER WINDS ALONG LAKE BREEZE
BOUNDARIES...WHICH ALSO MAY CONCENTRATE LOW-LEVEL
VORTICITY/ASCENT/SRH LOCALLY.
CONVECTIVE COVERAGE MAY BE LIMITED BY WEAK/WLY LOW LEVEL WINDS AND
LACK OF MORE ROBUST CONVERGENCE AWAY FROM LAKE BREEZE AND
DIFFERENTIAL HEATING BOUNDARIES IN NEAR-TERM. HOWEVER...REGIME
FARTHER W -- DESCRIBED IN MESOSCALE DISCUSSION 1151 -- MAY CROSS ONT
AND AFFECT THIS REGION LATER THIS AFTERNOON.
