AREAS AFFECTED...SERN TX INTO SWRN LA

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 200412Z - 200545Z

A CONTINUED INCREASE IN STORM COVERAGE AND INTENSITY IS EXPECTED
THROUGH 06Z. ISOLATED HAIL AND/OR LOCALLY DAMAGING WINDS WILL BE
THE PRIMARY SEVERE WEATHER HAZARDS...THOUGH A TORNADO OR TWO IS
POSSIBLE. CONVECTIVE TRENDS ARE BEING MONITORED FOR A POSSIBLE WW.

A RAPID INCREASE IN TSTM DEVELOPMENT HAS OCCURRED OVER THE PAST HALF
HOUR OVER SERN TX FROM NEAR TO UTS TO N OF LFK. WATER VAPOR
IMAGERY...RUC DIAGNOSTIC FIELDS AND REGIONAL VWP/PROFILER DATA ALL
SUGGEST THAT DEEP LAYER FORCING FOR ASCENT IS RAPIDLY STRENGTHENING
ACROSS AREA...LIKELY CONTRIBUTING TO THIS INCREASE IN CONVECTIVE
DEVELOPMENT. THESE STORMS APPEAR TO BE DEVELOPING ALONG THE ERN
EDGE OF STRONGER CAPPING OBSERVED BY 00Z S TX SOUNDINGS WITHIN A
MOIST LOW-LEVEL ENVIRONMENT CHARACTERIZED BY DEWPOINTS IN THE
LOW/MID 60S AND MLCAPES OF 300-800 J/KG.

CURRENTLY...IT APPEARS THE MARGINAL INSTABILITY IS INHIBITING STORM
ORGANIZATION WITH MAJORITY OF ACTIVITY LIKELY SLIGHTLY ELEVATED.
HOWEVER WITH TIME...A FEW OF THE MORE INTENSE STORMS MAY BECOME
SURFACE-BASED WITHIN A RATHER STRONGLY SHEARED KINEMATIC ENVIRONMENT
WITH EFFECTIVE BULK SHEARS OF 45-55 KT AND EFFECTIVE SRH VALUES OF
250-350 M2/S2. LOCALLY DAMAGING WINDS AND SEVERE HAIL WILL BE THE
PRIMARY HAZARDS...THOUGH A TORNADO OR TWO WILL BE POSSIBLE WITH ANY
SUSTAINED SUPERCELLS.

SPC AC 200038

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0638 PM CST WED DEC 19 2007

VALID 200100Z - 201200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS EAST TX AND MUCH OF
LA...

..EAST TX/LOWER MS VALLEY...

STRONGER MID-HIGH LEVEL FLOW IS SLOWLY SPREADING ACROSS NERN MEXICO
INTO SOUTH TX...NOT TOO DISSIMILAR FROM LATE AFTERNOON SHORT RANGE
GUIDANCE. IN RESPONSE TO ASSOCIATED MID LEVEL SHORTWAVE
TROUGH...LOW LEVEL JET WILL INCREASE OVER ERN TX INTO THE ARKLATEX
REGION AFTER DARK. RESULTANT LARGE SCALE ASCENT SHOULD UNDOUBTEDLY
AID CONVECTIVE DEVELOPMENT...MOSTLY LIKELY SOMEWHAT ELEVATED GIVEN
THE STEEP LAPSE RATE ENVIRONMENT NOTED UPSTREAM AT BOTH DRT AND CRP.
OVER THE LAST FEW HOURS SHOWER ACTIVITY OVER THE UPPER TX COAST
INTO CNTRL LA HAS STRUGGLED...MOST LIKELY DUE TO WEAK FORCING AND
SOMEWHAT MEAGER INSTABILITY...AS NOTED AT BOTH SHV AND LCH. WITH
TIME...LOW LEVEL MOISTURE RETURN SHOULD PROVE SUFFICIENT IN
DESTABILIZING BOUNDARY LAYER PARCELS AS SFC DEW POINTS RISE THROUGH
THE 60S...NWD ALONG AN AXIS NEAR THE SABINE RIVER. GIVEN THE
STRENGTHENING DEEP LAYER SHEAR WITHIN AN INCREASING WARM ADVECTION
REGIME...ROBUST UPDRAFT DEVELOPMENT COULD CERTAINLY OBTAIN SUPERCELL
CHARACTERISTICS. AT THIS TIME IT APPEARS THE GREATEST SEVERE THREAT
WILL BE LARGE HAIL AND DAMAGING WINDS.

0640 PM CST WED DEC 19 2007

AREAS AFFECTED...HIGHER ELEVATIONS OF NORTHERN CA

CONCERNING...HEAVY SNOW

VALID 200040Z - 200515Z

HEAVY SNOW WILL INCREASE ACROSS THE HIGHER ELEVATIONS OF NORTHERN CA
THROUGH EARLY/MID EVENING...WITH LOWERING SNOW LEVELS LATER TONIGHT
AND THE POSSIBILITY OF 2 IN/HR RATES ABOVE 5000 FT.

LATEST SATELLITE IMAGERY FEATURES MOIST PLUME EXTENDING INTO THE
PACIFIC NORTHWEST/NORTHERN CA DOWNSTREAM OF POTENT/COLD UPPER TROUGH
CENTERED ABOUT 400 MILES OFF THE ORE COAST. INCREASING LARGE SCALE
ASCENT WILL LEAD TO STEADILY INCREASING PRECIPITATION RATES/HIGHER
ELEVATION SNOW THIS EVENING ACROSS NORTHERN CA...WITH A STRONG
WEST-SOUTHWEST MID LEVEL JET /75-100 KT AT 500 MB/ CONSIDERABLY
ENHANCING OROGRAPHIC LIFT INTO WEST-SOUTH FACING SLOPES. LATEST
MESONET OBSERVATIONS FROM NORTHERN CA SUGGEST SNOW LEVELS ARE
RUNNING AROUND 4000-4500 FT LATE THIS AFTERNOON...WITH A STEADY DROP
/1000 FT OR MORE/ EXPECTED LATER TONIGHT /ESPECIALLY AFTER 06Z/ VIA
THE ARRIVAL OF COLDER AIR ALOFT WITH -30C AT 500 MB. AMPLE
LIFT/PACIFIC MOISTURE AND STEEPENING MID LEVEL RATES WITH CONVECTIVE
SNOW POTENTIAL WILL FAVOR THE POSSIBILITY OF 2 IN/HR SNOW RATES
ABOVE 5000 FT FROM THE SHASTA/SISKIYOU VICINITY INTO THE NORTHERN
SIERRA.

EVENING. IN ADVANCE OF THIS FEATURE...LOW LEVEL WINDS OVER EAST TX/
LA WILL BACK TO A MORE SLY COMPONENT AND SLOWLY STRENGTHEN WITH
ADDITIONAL INFLUX OF GULF MOISTURE. THIS COMBINED WITH STEEPENING
LAPSE RATES ATTENDANT TO APPROACH OF UPPER TROUGH WILL ESTABLISH A
MARGINALLY UNSTABLE AIRMASS ACROSS THE AREA. BY EVENING...SURFACE
DEWPOINTS IN THE MID 60S ARE LIKELY ACROSS MUCH OF SOUTHEAST TX AND
SOUTHWEST LA. INCREASING LARGE SCALE ASCENT AND COOLING ASSOCIATED
WITH UPPER TROUGH WILL LIKELY YIELD MUCAPE VALUES OF 500-1000 J/KG
OVER MUCH OF EAST TX AND WESTERN LA AFTER 06Z.

EARLY AFTERNOON MESOSCALE ANALYSES AND REGIONAL RADARS SHOWED
SHALLOW CONVECTION FROM VICINITY OF HOU NEWD INTO SE TX DEVELOPING
WITHIN MARGINALLY UNSTABLE AIR MASS /MLCAPE 250-500 J/KG/. UPPER
RIDGE OVER THIS REGION THIS AFTERNOON IS EXPECTED TO INHIBIT DEEP
CONVECTION FROM OCCURRING UNTIL LATER IN THE FORECAST PERIOD.
PRESENT INDICATIONS CONTINUE TO SUGGEST THAT INCREASING LOW LEVEL
WARM ADVECTION WILL HELP INITIATE SCATTERED TSTMS AROUND MIDNIGHT
ACROSS PARTS OF EAST TX...SPREADING ACROSS LA THROUGH THE MORNING
HOURS. FORECAST SOUNDINGS SHOW A SUFFICIENT COMBINATION OF ELEVATED
CAPE...MID LEVEL LAPSE RATES...AND DEEP LAYER VERTICAL SHEAR FOR A
RISK OF EMBEDDED SUPERCELLS CAPABLE OF LARGE HAIL AND DAMAGING
WINDS. BY LATE IN THE PERIOD...LOW LEVEL WINDS WILL STRENGTHEN
SUFFICIENTLY TO ALSO POSE A RISK OF TORNADOES IN THOSE STORMS THAT
ARE SURFACE-BASED.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1113 AM CST WED DEC 19 2007

VALID 201200Z - 211200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS E TX/LA EWD TO WRN FL
PANHANDLE...

..SYNOPSIS...
PROGRESSIVE AND AMPLIFIED SHORT WAVE TROUGH MOVING INTO THE SRN
PLAINS DURING DAY 1 PERIOD WILL TRACK EWD INTO THE LOWER MS VALLEY/
NWRN GULF BY LATE THURSDAY AFTERNOON /21/00Z/. THIS SYSTEM WILL
THEN MOVE EWD ACROSS THE CENTRAL GULF COAST STATES INTO THE SERN
U.S. THURSDAY NIGHT/EARLY FRIDAY MORNING. AT THE SURFACE...AN
ATTENDANT AREA OF LOW PRESSURE SHOULD BE LOCATED OVER THE LOWER RED
RIVER VALLEY OF NE TX/SE OK BY 20/12Z...AND THEN TRACK ENEWD INTO
NRN MS BY 21/00-06Z TIME FRAME. THIS LOW IS EXPECTED TO WEAKEN AS
IT MOVES INTO TN THURSDAY NIGHT AS IT ENCOUNTERS A DOWNSTREAM
SURFACE RIDGE OVER THE ERN UNITED STATES.

..SE TX TO CENTRAL GULF COAST REGION...
SHOWERS AND EMBEDDED TSTMS...SOME POSSIBLY STRONG TO SEVERE...WILL
LIKELY BE ONGOING ACROSS E TX/ARKLATEX REGION INTO THE LOWER MS
VALLEY AT 12Z THURSDAY. STRONG MID LEVEL DIFFLUENT FLOW REGIME/DPVA
AHEAD OF PROGRESSIVE SHORT WAVE TROUGH COMBINED WITH LOW LEVEL WAA
WILL MAINTAIN TSTM ACTIVITY DURING DAY 2 PERIOD EWD ACROSS LOWER MS
VALLEY TO CENTRAL GULF COAST STATES. STRONG SSWLY LLJ AT 45-55 KT
WILL SUPPORT MOISTURE INFLUX INTO THIS REGION WITH SURFACE DEWPOINTS
IN THE LOWER-MID 60S. THIS COMBINED WITH MID LEVEL COOLING/STEEP
LAPSE RATES WILL RESULT IN A MODERATELY UNSTABLE AIR MASS ACROSS THE
CATEGORICAL RISK AREA. STRONG SSWLY LLJ BENEATH 50 KT WSWLY MID
LEVEL WINDS WILL SUPPORT SUFFICIENTLY STRONG DEEP LAYER SHEAR FOR
BOTH EMBEDDED SUPERCELLS AND BOW STRUCTURES AS ACTIVITY DEVELOPS
EWD. MODELS CONTINUE TO INDICATE SEVERE POTENTIAL EFFECTIVELY BEING
SHUNTED SEWD WITH TIME...AS STRONGEST DEEP-LAYER FORCING OUTRUNS
MOST FAVORABLE BOUNDARY LAYER DESTABILIZATION.

FARTHER N INTO AR/NRN MS...MOISTURE RETURN WILL BE LESS AND THUS
RESULT IN WEAKER INSTABILITY. HOWEVER...THIS COMBINED WITH MODEST
DEEP LAYER SHEAR SHOULD SUPPORT AN ISOLATED THREAT FOR A FEW STRONG
TO SEVERE TSTMS PRODUCING MAINLY HAIL AND STRONGER WIND GUSTS.

PROGRESSIVE UPPER TROUGH NOW OVER AZ IS FORECAST TO TRACK EASTWARD
AND BEGIN AFFECTING THE SOUTHERN PLAINS BY LATE THIS AFTERNOON AND
EVENING. IN ADVANCE OF THIS FEATURE...SOUTHERLY LOW LEVEL WINDS
OVER EAST TX WILL SLOWLY STRENGTHEN...HELPING TO TRANSPORT GULF

AGREE IN GENERAL PRINCIPLE WITH DEEP SYNOPTIC-SCALE TROUGH EVOLVING
THROUGH DAY-4/22ND-23RD...FROM SEVERAL SHORTWAVE PERTURBATIONS NOW
EVIDENT IN MOISTURE CHANNEL IMAGERY OVER N-CENTRAL PACIFIC AND GULF

4-5/22ND-24TH. CONSIDERABLE SPREAD EXISTS AMONGST THOSE GUIDANCE
PACKAGES....HOWEVER...REGARDING RELATIVE IMPACT OF NRN AND SRN
STREAM SHORTWAVE TROUGHS WITHIN SYNOPTIC SCALE SYSTEM...AND THEIR
EFFECTS ON BOTH SFC CYCLOGENESIS AND MOIST RETURN FLOW. MOST

VALID 211200Z - 221200Z

..NO SVR TSTM AREAS FORECAST...

..SYNOPSIS...
UPPER AIR PATTERN IS FCST TO REMAIN PROGRESSIVE THROUGH REMAINDER
PERIOD ACROSS CONUS. INITIAL SHORTWAVE TROUGH NOW OVER SRN CA AND
NRN BAJA SHOULD MOVE ACROSS SRN CONUS THROUGH DAY-2...THEN OFFSHORE
CAROLINAS/GA/FL EARLY IN THIS PERIOD. MUCH STRONGER/UPSTREAM WAVE
IS EXPECTED TO DEVELOP OVER ERN PACIFIC FROM PHASING SHORTWAVE
TROUGHS AND SPEED MAXIMA...THEN MOVE INLAND TO GREAT BASIN AND NRN
ROCKIES DAY-2. BY 22/00Z...OPERATIONAL WRF/SPECTRAL AND MOST SREF
MEMBERS AGREE STRONGLY ON GENERAL PATTERN OF SYNOPTIC TROUGH FROM
DAKOTAS SSWWD ACROSS NM...WITH SOME POTENTIAL FOR CLOSED LOW TO FORM
FROM NRN STREAM SHORTWAVE TROUGH ACROSS EITHER NRN PLAINS OR
ADJACENT CANADIAN PRAIRIES. HOWEVER...CONSIDERABLE VARIATION IS
EVIDENT AMONGST VARIOUS GUIDANCE PACKAGES ON MOST PERTINENT SECTOR
OF MID-UPPER SYSTEM...NAMELY WITH STRENGTH/TIMING OF SHORTWAVE
MOVING THROUGH BASE OF TROUGH CROSSING SRN HIGH PLAINS DURING LATTER
HALF OF PERIOD. OPERATIONAL WRF/SPECTRAL REPRESENT WEAK/STRONG
EXTREMES RESPECTIVELY WITH THIS WAVE...WITH ECMWF AND MOST SREF
MEMBERS MORE REASONABLY SHOWING MDT AMPLITUDE PERTURBATION AND WEAK
SFC CYCLOGENESIS ALONG COLD FRONT.

SFC COLD FRONT SHOULD MOVE ACROSS CENTRAL/SRN PLAINS DURING
PERIOD...EXTENDING BY 22/12Z FROM UPPER MS VALLEY SSWWD ACROSS
OZARKS TO ARKLATEX AND S-CENTRAL TX.

..W GULF COASTAL PLAIN...
SOME SVR POTENTIAL MAY DEVELOP NEAR END OF PERIOD...AS COLD FRONT
BEGINS TO IMPINGE ON NRN/NWRN PORTIONS OF RETURN FLOW IN MOIST
SECTOR. MAIN UNCERTAINTIES FOR THIS FCST INVOLVE
STRENGTH/POSITIONING OF FAVORABLE LARGE SCALE SUPPORT ALOFT
DISCUSSED ABOVE...AS WELL AS OF RICHEST BOUNDARY LAYER MOISTURE.
UNCHARACTERISTICALLY...OPERATIONAL WRF APPEARS TO BE WEAKER WITH
RETURN FLOW THAN 00Z SPECTRAL AND SEVERAL SREF MEMBERS. VERTICAL
SHEAR PROFILES ARE EXPECTED TO STRENGTHEN CONSIDERABLY ACROSS MOIST
SECTOR AHEAD OF UPPER TROUGH...SO AT LEAST MRGL SVR PROBABILITIES
ARE WARRANTED. HOWEVER...MORE AGGRESSIVE OUTLOOK IS PRECLUDED ATTM
BY APPARENT HORIZONTAL DISPLACEMENT BETWEEN STRONGEST LIFT AND MOST
FAVORABLE MOISTURE BEFORE END OF PERIOD.

VALID 201200Z - 211200Z

..THERE IS A SLGT RISK OF SVR TSTMS PORTIONS E TX...LA TO WRN FL
PANHANDLE...

..SYNOPSIS...
PROGRESSIVE MID/UPPER LEVEL PATTERN WILL CONTINUE...WITH MOST
CRITICAL FEATURE BEING SHORTWAVE TROUGH NOW EVIDENT IN MOISTURE
CHANNEL IMAGERY OVER SRN CA SWD TO JUST OFFSHORE NRN BAJA. THIS
TROUGH IS FCST TO MOVE EWD TO ERN OK AND N-CENTRAL/CENTRAL TX BY
20/12Z...THEN REACHING SC...ERN GA AND PERHAPS NRN FL BY 21/12Z. AT
SFC...LEE TROUGHING WITH WEAK EMBEDDED LOWS -- NOW ANALYZED FROM ERN
CO SWD ACROSS ERN NM AND SW TX -- IS EXPECTED TO CONSOLIDATE INTO
DISCRETE LOW DAY-1 BEFORE MOVING ESEWD/SEWD TOWARD RED RIVER N-NE OF
DAL BY 20/12Z. THIS LOW THEN SHOULD MOVE EWD ACROSS NRN MS BETWEEN
21/00-21/06Z BEFORE BECOMING DIFFUSE INVOF NWRN AL/NERN MS. DRYLINE
WILL BECOME BETTER DEFINED AND MOVE EWD ACROSS WRN/CENTRAL TX
THROUGH BEGINNING OF PERIOD AS DEW POINTS INCREASE TO ITS E...WITH
SIGNIFICANT WLY WIND COMPONENT TO ITS W.

..SE TX TO CENTRAL GULF COAST REGION...
ONGOING POTENTIAL EXISTS FROM END OF DAY-1 PERIOD OVER PORTIONS E TX
AND LA...WITH ADDITIONAL DEVELOPMENT OF SCATTERED TSTMS POSSIBLE IN
EWD-SHIFTING BANDS AND CLUSTERS DURING DAY. MAIN THREATS WILL
TRANSITION FROM ISOLATED HAIL OVER PARTS OF NE TX...AR AND NWRN
NS...TO WIND DAMAGE AND A FEW TORNADOES WITH PROXIMITY TO COAST.
THIS IS BECAUSE SFC-BASED DESTABILIZATION IS EXPECTED TO DIMINISH
WITH INLAND EXTENT...ESPECIALLY N OF I-20 IN LA/MS...GIVEN BOTH
INCOMPLETENESS OF RETURN FLOW MODIFICATION FROM GULF AND EFFECTS OF
CLOUDS/PRECIP. STRONG BUT NARROW ZONE OF MIDLEVEL DPVA IS FCST TO
PRECEDE TROUGH AS IT MOVES EWD OVER ARKLATEX REGION AND INTO MS.
THIS WILL COINCIDE WITH DIURNAL HEATING ACROSS PORTIONS NRN CENTRAL
LA AND PERHAPS SWRN MS...PROVIDING ADDITIONAL CONTRIBUTION TO
STEEPENING OF DEEP-LAYER LAPSE RATES. INFLOW LAYER IS EXPECTED TO
BECOME PROGRESSIVELY MORE ELEVATED WITH NWD EXTENT OVER NRN
LA...AR...NRN MS AND WRN TN...THOUGH ISOLATED HAIL MAY BE POSSIBLE.

AIR MASS MODIFICATION IS WELL UNDERWAY OVER ROUGHLY WRN HALF OF GULF
BASED ON PW DATA AND SFC-850 MB ISODROSOTHERMAL ANALYSIS TRENDS.
LATEST BRO/CRP RAOBS AND GPS DATA INDICATE 1-1.25 INCH PW...WITH
CIRA SATELLITE BASED INDICATIONS OF 1.25-1.5 INCH OVER SHELF WATERS
BETWEEN BRO-TAMPICO...AND OBSERVED 66-70 DEG F SFC DEW POINTS OVER
WRN GULF S OF 26N. PRIND LOW-MID 60S F DEW POINTS WILL SPREAD NEWD
ACROSS CATEGORICAL OUTLOOK AREA BENEATH INCREASING FLOW ALOFT. LOW
LEVEL HODOGRAPHS SHOULD BE FAVORABLE FOR BOTH SUPERCELLS AND SMALL
BOWS...GIVEN ANTICIPATED BLEND OF LINEAR AND CLUSTERED CONVECTIVE
MODES. SVR POTENTIAL EFFECTIVELY WILL BE SHUNTED SEWD WITH
TIME...AS STRONGEST DEEP-LAYER FORCING OUTRUNS MOST FAVORABLE
BOUNDARY LAYER DESTABILIZATION AND MOVES OVER SMALLER THETAE IN LOW
LEVELS.

NWS STORM PREDICTION CENTER NORMAN OK
1152 PM CST TUE DEC 18 2007

VALID 191200Z - 201200Z

..THERE IS A SLGT RISK OF SVR TSTMS FROM ERN PORTIONS OF THE SRN
PLAINS EWD INTO THE LOWER MS VALLEY REGION...

..SYNOPSIS...
PROGRESSIVE MID-LEVEL FLOW PATTERN TO PERSIST ACROSS THE U.S. THIS
PERIOD...WITH SEVERAL SHORT-WAVE FEATURES FORECAST TO MOVE
RELATIVELY QUICKLY FROM W-E ACROSS THE CONUS. THE MAIN FEATURE IN
TERMS OF THE CONVECTIVE FORECAST WILL BE THE SHORT-WAVE TROUGH
INITIALLY EXTENDING N-S ACROSS THE ROCKIES AND INTO THE DESERT SW.
THIS FEATURE IS FORECAST TO SHIFT INTO THE PLAINS DURING THE SECOND
HALF OF THE PERIOD...ALONG WITH A WEAK/ACCOMPANYING SRN PLAINS
SURFACE CYCLONE AND AN INCREASING SSWLY LOW-LEVEL JET. RESULTING
NWD ADVECTION OF LOW-LEVEL MOISTURE INTO THE SRN PLAINS/LOWER MS
VALLEY SHOULD LEAD TO AN INCREASE IN THUNDERSTORM POTENTIAL THROUGH
THE SECOND HALF OF THE PERIOD.

..ERN TX INTO LA AND PARTS OF SWRN MS...
MARGINAL DESTABILIZATION IS FORECAST -- PARTICULARLY AFTER SUNSET --
FROM ERN PORTIONS OF THE SRN PLAINS INTO THE LOWER MS VALLEY...AS
SLY/SSWLY LOW-LEVEL FLOW ADVECTS MOISTURE NWD BENEATH STEEPER LAPSE
RATES SPREADING EWD WITHIN WLY FLOW ALOFT.

MOST OF THE THUNDERSTORM DEVELOPMENT -- LIKELY LIMITED PRIMARILY TO
THE SECOND HALF OF THE PERIOD -- SHOULD OCCUR ATOP A SHALLOW/MORE
STABLE SURFACE LAYER. HOWEVER...DEGREE OF INSTABILITY AND
MODERATE/VEERING FLOW WITH HEIGHT SHOULD BE SUFFICIENT FOR SOME
STORM ORGANIZATION/ROTATION. A FEW OF THE STRONGER STORMS MAY
PRODUCE MARGINAL HAIL...AND MODEST/SHALLOW NATURE OF THE STABLE
LAYER SUGGESTS AT LEAST A MINIMAL POTENTIAL FOR A COUPLE OF
SURFACE-BASED WIND GUSTS AT OR NEAR SEVERE LEVELS.
