TORNADO WATCH NUMBER 918
NWS STORM PREDICTION CENTER NORMAN OK
655 PM MDT SAT OCT 11 2008

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

EASTERN NEW MEXICO
FAR WESTERN OKLAHOMA PANHANDLE
WEST CENTRAL AND WESTERN PARTS OF THE TEXAS PANHANDLE

EFFECTIVE THIS SATURDAY NIGHT AND SUNDAY MORNING FROM 655 PM
UNTIL 100 AM MDT.

TORNADOES...HAIL TO 1.5 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 95 STATUTE
MILES NORTH AND SOUTH OF A LINE FROM 30 MILES SOUTHEAST OF
DALHART TEXAS TO 80 MILES NORTHWEST OF ROSWELL NEW MEXICO. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU8).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND 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.

OTHER WATCH INFORMATION...CONTINUE...WW 916...WW 917...

DISCUSSION...SCTD TSTMS/SUPERCELLS EXPECTED TO PERSIST ALONG SSW-NNE
CONFLUENCE ZONE IN E CNTRL/SE NM. OTHER STORMS EXPECTED TO PERSIST
ALONG SIMILAR CONFLUENCE BAND IN MORE DEEPLY-MIXED ENVIRONMENT IN N
CNTRL/ NE NM. STRENGTH OF EXISTING WIND FIELD...LIKELIHOOD FOR SOME
BACKING/STRENGTHENING OF NEAR-SFC FLOW...AND MOIST BOUNDARY LAYER
OVER ERN NM SUGGEST POTENTIAL FOR ISOLD BUT POSSIBLY STRONG
TORNADOES OVER THAT PART OF THE STATE AND IN ADJACENT PARTS OF TX.
HAIL/LOCALLY DMGG WIND WILL REMAIN POSSIBLE WITH STORMS IN THE N
CNTRL/NE NM.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
450. MEAN STORM MOTION VECTOR 22040.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0755 PM CDT SAT OCT 11 2008

VALID 120100Z - 121200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER CNTRL/ERN NM AND WRN TX
NWD INTO SERN CO AND SWRN KS...

...CNTRL/SRN ROCKIES INTO THE HIGH PLAINS...

INTENSE MID AND UPPER-LEVEL LOW CENTERED OVER THE GREAT BASIN WILL
SLOWLY DEVELOP EWD TONIGHT AS 130+ KT HIGH-LEVEL JET STREAK
PROPAGATES NEWD FROM THE FOUR CORNER REGION INTO THE NRN/CNTRL HIGH
PLAINS. EVENING WATER VAPOR IMAGERY INDICATES A SMALLER-SCALE SHORT
WAVE OVER CO WHICH WILL CONTINUE NEWD INTO THE DAKOTAS OVERNIGHT.
IN THE LOW-LEVELS...PRIMARY SURFACE CYCLONE WILL DEVELOP EWD ACROSS
CO WITH TRAILING PACIFIC FRONT PUSHING EWD THROUGH THE CNTRL/SRN
ROCKIES.

A COUPLE OF LOOSELY ORGANIZED BANDS OF TSTMS /INCLUDING SUPERCELLS/
ARE IN PROGRESS AS OF 01Z...ONE FROM SERN CO TO JUST E OF ABQ...AND
THE OTHER FROM NEAR DHT TO JUST E OF ELP. PLAN VIEW VWP DATA AND
SHORT TERM MODEL GUIDANCE SUGGEST THAT THIS ACTIVITY IS OCCURRING
WITHIN A BROADLY CONFLUENT LOW-LEVEL FLOW REGIME WHERE LOW-LEVEL
MASS CONVERGENCE IS BEING ENHANCED. DESPITE A WARMER AND MORE MOIST
BOUNDARY LAYER CONDITIONS PRESENT OVER WRN TX/ERN NM...00Z REGIONAL
SOUNDINGS INDICATE THAT THE STRONGEST INSTABILITY EXISTS OVER CNTRL
NM /I.E. SBCAPE AROUND 1000 J PER KG/ OWING LARGELY TO COMPARATIVELY
COOLER MIDLEVEL THERMAL PROFILES AND RESULTANT STEEPER LAPSE RATES.

INCREASED MOISTURE FLUX AND LOW-LEVEL ASCENT ALONG 40-50 KT
NOCTURNAL LLJ...COMBINED WITH STEEPENING MIDLEVEL LAPSE RATES FROM
THE W WILL LIKELY FOCUS A N-S CORRIDOR OF STRONG/SEVERE TSTMS
OVERNIGHT OVER PORTIONS OF ERN NM/WRN TX NWD INTO ERN CO/WRN KS.
THE PRESENCE OF STRONG LOW AND DEEP-LAYER SHEAR IN ADDITION TO A
WEAK LOW-LEVEL BAROCLINIC ZONE ACROSS E-CNTRL NM INTO THE SRN TX
PNHDL /REF MCD 2329/ SUGGEST THE POTENTIAL FOR A TORNADO OR TWO WITH
ANY MORE INTENSE SUPERCELLS THAT MAY DEVELOP. OTHERWISE...HAIL AND
LOCALLY STRONG WIND GUSTS WILL REMAIN THE PRIMARY SEVERE WEATHER
THREATS.

CONCERNING...SEVERE THUNDERSTORM WATCH 916...917...

VALID 120046Z - 120215Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
916...917...CONTINUES.

SEVERE THUNDERSTORM WATCH 916 COVERING CNTRL/NRN NM AND EXTREME
SCNTRL CO IS SET TO EXPIRE AT 02Z...BUT MAY NEED TO BE EITHER
REPLACED OR EXTENDED BY LOCAL WEATHER FORECAST OFFICES PENDING
CURRENT STORM EVOLUTIONS.

WEAK RIDGING/SUBSIDENCE WAS SPREADING NEWD IN WAKE OF A SHORTWAVE
IMPULSE ROTATING NWD OUT OF CNTRL NM AND WAS LIKELY RESPONSIBLE FOR
DECREASING TSTMS UPSTREAM ACROSS SE AZ/NRN MEXICO. BAND OF
MORE-OR-LESS DISCRETE STORMS CONTINUES AHEAD OF THE WAVE FROM SERN
CO INTO THE KLVS AREA. THESE STORMS WILL CONTINUE NEWD INTO THE
NERN NM PLAINS AND EXTREME SERN CO THROUGH THE REMAINDER OF THE
EVENING. NOCTURNAL COOLING AND INFLOW FROM THE BAND OF STORMS ALONG
THE TX/NM BORDER WILL LIKELY DECREASE THE SVR THREATS...ESPECIALLY
TORNADO RISKS AS EFFECTIVE PARCELS BECOME ROOTED ABOVE THE SFC.

MEANWHILE...HIGHER SVR POTENTIAL WILL REMAIN FROM FAR W TX NEWD INTO
SERN/ECNTRL NM AND INTO THE FAR WRN TX PNHDL. HERE...MIXED STORM
MODES CONSISTING OF BOWS AND DISCRETE CELLS CONTINUE TO
THRIVE...FEEDING ON STRONGER INSTABILITY. H85-H7 SLY JET IS
EXPECTED TO INCREASE THROUGH 06Z COINCIDENT WITH THE EWD EDGING OF
STEEPER LAPSE RATES ALOFT. THIS SUGGESTS THAT THREATS FOR LARGE
HAIL AND DMGG WIND GUSTS WILL REMAIN FOCUSED ALONG THE TX/NM BORDER
FOR SEVERAL MORE HOURS THIS EVENING. MOREOVER...STRONG LOW-LEVEL
TURNING AND MAINTENANCE OF SFC-BASED EFFECTIVE PARCELS WILL CONTINUE
THE RISK FOR A TORNADO OR TWO WITH DISCRETE CELLS. PARTS OF THE
REGION WILL LIKELY BE UPGRADED TO A TORNADO WATCH SHORTLY.

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 112204Z - 112330Z

A NEW BAND OF DISCRETE TSTMS HAS BEEN INTENSIFYING FROM NRN
CHIHUAHUA INTO WRN HUDSPETH/ERN EL PASO COUNTIES IN TX AND CNTRL
OTERO COUNTY NM. IT IS TOUGH TO IDENTIFY ANYTHING IN WATER VAPOR
IMAGERY THAT MAY BE AIDING IN LARGER SCALE ASCENT...BUT REGION DOES
REMAIN ALONG SERN PERIPHERY OF THE GIANT GRT BASIN GYRE...LIKELY
RESULTING IN AT LEAST WEAK ASCENT.

REGION RESIDES WHERE THE STRONGEST HEATING OCCURRED THIS AFTN WITH
AMPLE BOUNDARY LAYER MOISTURE AND SELY UPSLOPE FLOW REGIME. AS A
RESULT...TSTMS ARE EXPECTED TO CONTINUE DEVELOPING ACROSS THIS
REGION FOR SEVERAL MORE HOURS. SW MID-LVL FLOW OF 45-50 KTS ATOP
THE SELY SFC TRAJECTORIES ARE RESULTING IN A HIGHLY SHEARED
ENVIRONMENT WITH SPLITTING SUPERCELLS LIKELY WITH POSSIBLE LARGE
HAIL AND DMGG WINDS. IF A STORM CAN BECOME WELL-ESTABLISHED...AN
ISOLD TORNADO MAY ALSO OCCUR.

LATER THIS EVENING...MODELS AND SATL LOOPS SUGGEST THAT WARMING
ALOFT...TIED TO REMNANT TC NORBERT...WILL OVERSPREAD THE REGION FROM
SOUTH TO NORTH. THUS...THERMODYNAMIC ENVIRONMENT WILL LIKELY BECOME
MORE HOSTILE FOR VIGOROUS UPDRAFTS FROM MID-LATE EVENING. UNTIL
THEN...HOWEVER...A WW MAY BE WARRANTED.

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 915
CONTINUES.

LONG-LIVED STRONG/SEVERE STORM WHICH HAS EXHIBITED PERIODIC
SUPERCELL CHARACTERISTICS HAS MOVED FROM SERN AZ INTO NRN GRANT CNTY
NM. THIS STORM IS LIKELY TO APPROACH OR MOVE INTO THE SWRN PART OF
WW 916 BY 21Z. OTHER STRONG THUNDERSTORMS CONTINUE WITHIN THE
TROPICAL MOISTURE PLUME EXTENDING ACROSS SERN AZ INTO SWRN/WEST
CENTRAL NM...ALTHOUGH LIGHTNING DATA HAVE SHOWN A DECREASE IN FLASH
DENSITY DURING THE LAST 1-2 HRS ESPECIALLY OVER SERN AZ.

WARM MOIST LOW LEVEL AIR MASS IS REMAINING OVER PARTS OF SERN AND
EAST CENTRAL AZ AHEAD OF A COLD FRONT AND PRE-FRONTAL DRY LINE
MOVING ACROSS ERN AZ. HOWEVER...STRONG UPPER TROUGH AND ASSOCIATED
COLD AIR ALOFT CENTERED OVER THE GREAT BASIN APPEAR TO BE NO LONGER
DIGGING SEWD. IN ADDITION...WARM AIR ALOFT ACCOMPANYING HURCN
NORBERT IS EXPECTED TO CONTINUE SPREADING NEWD INTO SERN AZ AND SWRN
NM LIMITING FURTHER DESTABILIZATION. DESPITE STRONG WINDS AND
VERTICAL SHEAR OVER THE REGION THERE IS UNCERTAINTY REGARDING EXTENT
OF SEVERE THREAT CONTINUING OVER THIS AREA. UNLESS NEAR-TERM
OBSERVATIONAL DATA SHOW AN INCREASE IN STORM INTENSITY PRIOR TO
21Z...A NEW WW IS NOT EXPECTED TO BE ISSUED. UNDER THESE
CIRCUMSTANCES WFO/S TWC AND EPZ CAN LOCALLY EXTEND IN TIME PARTS OF

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0254 PM CDT SAT OCT 11 2008

VALID 112000Z - 121200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN
ROCKIES...SRN HIGH PLAINS AND CNTRL HIGH PLAINS......

...SRN ROCKIES/SRN AND CNTRL HIGH PLAINS...
A STRONG UPPER-LEVEL LOW EVIDENT ON WATER VAPOR IMAGERY IS LOCATED
ACROSS THE INTERMOUNTAIN WEST WITH SOUTHWEST FLOW IN PLACE FROM THE
SRN ROCKIES NEWD INTO THE CNTRL PLAINS. THE LEADING EDGE OF A
WELL-DEFINED DRY SLOT EXISTS FROM SE AZ NEWD INTO NW NM. SCATTERED
THUNDERSTORMS ARE ONGOING AHEAD OF THE DRY SLOT AND THIS ACTIVITY
SHOULD SLOWLY EXPAND EWD COVERAGE REACHING ERN NM...WEST TX AND SW
KS LATER THIS EVENING.

CONCERNING THE STORM ENVIRONMENT...A POWERFUL 100 TO 115 KT
MID-LEVEL JET OVER THE FOUR CORNERS REGION WILL CONTINUE NEWD THIS
AFTERNOON HELPING TO CREATE STRONG VERTICAL SHEAR PROFILES ACROSS
MUCH OF THE SLIGHT RISK AREA. IN FACT...THE ALBUQUERQUE AND
ALAMOGORDO NM WSR-88D VWPS SHOW IMPRESSIVE WIND PROFILES WITH ABOUT
50 KT OF FLOW AT 2 TO 3 KM AND SOME DIRECTIONAL SHEAR. THIS SHOULD
EASILY SUPPORT ROTATING STORMS IN SPITE OF THE WEAKER INSTABILITY IN
PLACE ATTM. THE RUC SUGGESTS SBCAPE VALUES CURRENTLY RANGE FROM 500
TO 1000 J/KG ACROSS MUCH OF THE SLIGHT RISK AREA AND INSTABILITY MAY
INCREASE A BIT MORE LATE THIS AFTERNOON. WITH 500 MB TEMPS IN THE -7
TO -10 C RANGE AND MID-LEVEL LAPSE RATES EXCEEDING 7.0 C/KM...HAIL
WILL BE LIKELY WITH ROTATING STORMS. LARGE HAIL AND ISOLATED WIND
DAMAGE WILL BE POSSIBLE IN A FEW SPOTS WHERE ISOLATED SUPERCELLS
HAVE ACCESS TO LOCALLY MAXIMIZED INSTABILITY. IN ADDITION...AN
ISOLATED TORNADO THREAT MAY ALSO DEVELOP IN A CORRIDOR FROM NE NM
INTO SW KS EARLY THIS EVENING JUST TO THE WEST OF THE LOW-LEVEL JET
WHERE MOISTURE ADVECTION AND LOW-LEVEL SHEAR ARE FORECAST TO BE MOST
FAVORABLE. A SEVERE THREAT WILL ALSO BE POSSIBLE FURTHER SOUTH INTO
THE LUBBOCK AND MIDLAND TX AREAS WHERE SFC DEWPOINTS SHOULD BE IN
THE LOWER 60S F AND MODERATE INSTABILITY MAY EXIST BY EARLY THIS
EVENING.

AREAS AFFECTED...ERN AZ/WRN NM

CONCERNING...SEVERE THUNDERSTORM WATCH 915...

VALID 111756Z - 111930Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 915
CONTINUES.

STRONG/SEVERE THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE
THROUGH THE LATE MORNING AND EARLY AFTERNOON ACROSS WW 915.

STORMS HAVE BEEN OCCURRING ACROSS SERN/EAST CENTRAL AZ INTO WRN NM
WITHIN THE TROPICAL MOISTURE PLUME EMANATING FROM HURCN NORBERT. A
PERSISTENT RIGHT-MOVING SUPERCELL HAS BEEN TRACKING ENEWD ACROSS NRN
COCHISE CNTY AZ DURING THE LAST HOUR...AND OTHER STORMS ARE
INCREASING IN A NE-SW LINE FROM EXTREME SRN NAVAJO CNTY AZ INTO SRN
PINAL CNTY AZ.

THE INTERACTION OF THE HIGH AMPLITUDE COLD WRN TROUGH WITH THE WRN
EDGE OF THE MOISTURE PLUME IS PROVIDING AN ENVIRONMENT SUPPORTIVE OF
SEVERE STORMS. LATEST VAD PROFILES EXHIBIT VERY STRONG SWLY
WINDS/VERTICAL WIND SHEAR WITH 50 KT FLOW WITHIN 1-2 KM AGL AND A
100+ KT UPPER LEVEL JET STREAK LIFTING NEWD ACROSS NRN AZ. VISIBLE
IMAGERY SHOWS BREAKS IN CLOUD COVER WHERE LOCALIZED HEATING WILL
OCCUR IN ADVANCE OF A STRONG EASTWARD MOVING COLD FRONT
CHARACTERIZED BY STRONG DRYING AND PRESSURE RISES. THIS INDICATES
SEVERE STORM POTENTIAL IS LIKELY TO INCREASE INTO THE AFTERNOON WITH
A THREAT FOR DAMAGING WINDS AND LARGE HAIL. GIVEN THE STRONG
VERTICAL SHEAR SUPPORTIVE OF SUPERCELLULAR STRUCTURES...AN ISOLATED
TORNADO MAY ALSO BE POSSIBLE.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1211 PM CDT SAT OCT 11 2008

VALID 121200Z - 131200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN AND
CNTRL HIGH PLAINS...

...SRN AND CNTRL HIGH PLAINS...
A STRONG UPPER-LEVEL LOW OVER THE INTERMOUNTAIN WEST IS FORECAST IS
TO LIFT QUICKLY NEWD TONIGHT AND INTO THE NRN HIGH PLAINS SUNDAY. A
LARGE UPPER-LEVEL TROUGH ASSOCIATED WITH THE SYSTEM SHOULD REMAIN
NEARLY STATIONARY WITH A LONG FETCH OF SOUTHWEST FLOW IN PLACE FROM
THE SRN ROCKIES INTO THE SRN AND CNTRL HIGH PLAINS. AT THE SFC...A
LOW SHOULD BE LOCATED IN ERN CO BY MIDDAY SUNDAY WITH A PACIFIC COLD
FRONT EXTENDING SWD ACROSS THE SRN ROCKIES. SCATTERED CONVECTION
MOSTLY ELEVATED IN NATURE IS FORECAST BY THE MODELS TO BE ONGOING
ALONG OR AHEAD OF THE BOUNDARY EARLY IN THE PERIOD DUE TO LIFT
ASSOCIATED WITH THE LOW-LEVEL JET AND LARGE-SCALE ASCENT AHEAD OF A
SUBTLE SHORTWAVE. DAYTIME SFC HEATING AND DESTABILIZATION SHOULD
ALLOW FOR SFC-BASED THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON
ESPECIALLY ACROSS ERN NM AND WEST TX WHERE SFC DEWPOINTS MAY REACH
THE LOWER 60S F AND THE MOIST LAYER IS FORECAST TO EXTEND TO ABOUT
700 MB.

CONCERNING THE SEVERE POTENTIAL...A POWERFUL 90 TO 110 KT MID-LEVEL
JET IS FORECAST TO EJECT OUT OF THE BASE OF THE TROUGH INTO THE
CNTRL ROCKIES DURING THE DAY ON SUNDAY. THE ERN PART OF THIS JET
SHOULD INFLUENCE THE SLIGHT RISK AREA CREATING MODERATE TO STRONG
VERTICAL SHEAR PROFILES WITH 0-6 KM SHEAR VALUES REACHING 45 TO 55
KT. THIS ALONG WITH ALONG WITH A GRADUALLY VEERING WINDS WITH HEIGHT
BELOW 700 MB EVIDENT ON FORECAST SOUNDINGS SHOULD PROVIDE SUPPORT
FOR ROTATING STORMS. DUE TO THE RATHER WEAK INSTABILITY
FORECAST...THE SEVERE THREAT WILL LIKELY REMAIN ISOLATED ACROSS THE
SLIGHT RISK AREA. THE AMOUNT OF LOW-LEVEL SHEAR COULD RESULT IN A
TORNADO WITH ANY DOMINANT SUPERCELL THAT CAN PERSIST DURING MAX
HEATING. ANY ROTATING STORM WOULD LIKELY HAVE A THREAT FOR WIND
DAMAGE AND/OR A LOW-END THREAT FOR HAIL. THE WIND DAMAGE POTENTIAL
WOULD LIKELY BE MORE LIMITED ACROSS THE NRN PART OF THE SLIGHT RISK
AREA WHERE STORMS ARE LESS LIKELY TO BE SFC-BASED.

...THERE IS A SLGT RISK OF SVR TSTMS FROM ERN AZ INTO THE SRN HI
PLAINS...

...SYNOPTIC DISCUSSION...

UNSEASONABLY INTENSE UPPER LOW AND AN ACCOMPANYING VERY STRONG POLAR
JET MAX INITIALLY OVER SRN INTERMOUNTAIN REGION SHIFTS NEWD THIS
FORECAST PERIOD. LOW LEVEL MOISTURE IS RAPIDLY BECOMING INVOLVED
WITH THE SYSTEM AHEAD OF THE STRONG COLD FRONT. ONE SOURCE FROM
HURRICANE NORBERT HAS SPREAD NEWD ACROSS ERN AZ/WRN NM THIS AM.
ADDITIONALLY GULF OF MEXICO MOISTURE MOVING NWD THRU SRN HIGH
PLAINS.

SHALLOW COLD AIR HAS SETTLED SWD E OF CENTRAL ROCKIES TO A POSITION
FROM WRN KS/WRN OK PANHANDLE AND THEN WWD TO HIGHER TERRAIN ALONG
CO/NM BORDER. STRONG COLD FRONT EXTENDS FROM SURFACE LOW CENTRAL UT
SWD E OF PHX THEN TO AZ/MEX BORDER.

VERY IMPRESSIVE SHEAR PROFILES ARE SPREADING EWD ACROSS ERN AZ/NM AS
100 PLUS KT 500 MB JET ROTATES ACROSS NRN AZ INTO NWRN NM/WRN CO.

...ERN AZ/WRN NM...
THUNDERSTORMS DEVELOPED RAPIDLY EARLY THIS AM AS THE NORBERT
MOISTURE WAS DRAWN NWD AHEAD OF COLD FRONT NOW MOVING INTO ERN AZ.
STRONG/VEERING SHEAR PROFILES COUPLED WITH MLCAPES AOA 1000 J/KG PER
12Z TUS SOUNDING SUPPORT SEVERE THUNDERSTORMS INCLUDING LARGE HAIL
AND DAMAGING WINDS. PRIMARY STORM MODE SHOULD BE MULTICELLULAR
CLUSTERS...HOWEVER MORE THAN SUFFICIENT SHEAR FOR ISOLATED
SUPERCELLS.

STORMS NOW IN ERN AZ AHEAD OF COLD FRONT SHOULD CONTINUE TO INCREASE
WITH DAYTIME HEATING AS THEY DEVELOP INTO WRN NM THIS AFTERNOON.
WHILE HAIL/WIND PRIMARY THREAT...ISOLATED TORNADOES ARE POSSIBLE
WITH ANY SUPERCELL THAT DEVELOPS.

...SRN HIGH PLAINS...
OBSERVED STRONG CINH THIS AM ACROSS SRN HI PLAINS EXPECTED TO ERODE
SUFFICIENTLY BY MID AFTERNOON WITH APPROACH OF LARGE SCALE ASCENT
AND SURFACE HEATING TO SUPPORT SURFACE BASED INITIATION. WITH LOW
60F DEWPOINTS AND SURFACE TEMPS INTO THE 70S ERN NM...MLCAPES SHOULD
INCREASE TO NEAR 1000 J/KG WHICH WHEN COUPLED WITH THE PROGGED 50-60
KT DEEP LAYER SHEAR WILL SUPPORT SUPERCELL POTENTIAL.

THE SEVERE THUNDERSTORM THREAT WILL DEVELOP INITIALLY OVER HIGHER
TERRAIN OF NERN NM. STORMS WILL THEN DEVELOP NEWD ACROSS SERN CORNER
CO...NWRN TX/WRN OK PANHANDLE BY THIS EVENING WITH POTENTIAL FOR ONE
OR TWO TORNADO SUPERCELLS. LOW LEVEL CONVERGENCE SHOULD BE ENHANCED
VICINITY SHALLOW FRONTAL ZONE WHICH COULD MIX NWD BACK INTO SWRN KS
BY THIS EVENING.

ADDITIONAL MORE ISOLATED SEVERE STORMS ARE POSSIBLE FURTHER S THRU

AMENDED FOR SVR POTENTIAL SERN AZ/SWRN NM.

SVR POTENTIAL INCREASING ACROSS PORTIONS SERN AZ/SWRN NM. REF
MESOSCALE DISCUSSION 2324 AND WW 915 FOR MORE DETAILS.

...PREVIOUS DISCUSSION....

POWERFUL UPPER TROUGH OVER THE WESTERN STATES CONTINUES TO DEEPEN
THIS MORNING...WHILE PLUME OF TROPICAL MIDLEVEL MOISTURE ASSOCIATED
WITH HURRICANE NORBERT SPREADS NORTHEASTWARD INTO THE SOUTHERN
ROCKIES. THESE TWO FACTORS WILL COMBINE TO POSE A RISK OF SEVERE
THUNDERSTORMS TODAY OVER PARTS OF THE SOUTHERN HIGH PLAINS AND
SOUTHERN ROCKIES.

WATER VAPOR IMAGERY AND MODEL GUIDANCE SHOW WEAK IMPULSES AND
INCREASING FORCING FOR UPWARD VERTICAL MOTION EMBEDDED IN THE PLUME
OF MOISTURE EMANATING FROM HURRICANE NORBERT. THESE FEATURES WILL
TRACK NORTHEASTWARD ACROSS NORTHERN MEXICO AND INTO PARTS OF
NM/TX/SOUTHWEST KS THIS AFTERNOON AND TONIGHT. THIS WILL OCCUR AS
110+ KNOT MID LEVEL JET ROTATES THROUGH BASE OF WESTERN TROUGH AND
INTO THE FOUR CORNERS AREA. 500MB HEIGHT FALLS WILL COMMENCE BY
EVENING OVER CO/NM...FURTHER ENHANCING LARGE SCALE ASCENT AND
LEADING TO WIDESPREAD SHOWERS AND THUNDERSTORMS. RATHER LIMITED LOW
LEVEL MOISTURE AND AT LEAST SCATTERED CLOUD COVER WILL LIKELY LIMIT
UPDRAFT INTENSITY WITH STORMS OVER CENTRAL NM AND SOUTHERN CO.
NEVERTHELESS...STRONG WINDS ALOFT AND RATHER STEEP MID LEVEL LAPSE
RATES MAY RESULT IN GUSTY WINDS AND HAIL IN ANY STORMS.

THE WESTERN EDGE OF SURFACE DEWPOINTS IN THE 50S TO LOWER 60S WILL
REMAIN ESTABLISHED OVER EASTERN NM AND WEST TX THROUGH THE DAY.
POCKETS OF STRONG HEATING WILL HELP TO YIELD LATE AFTERNOON MLCAPE
VALUES OF 500-1000 J/KG ALONG THIS ZONE. FORECAST SOUNDINGS SUGGEST
DEEP LAYER AND LOW LEVEL VERTICAL SHEAR WILL BE FAVORABLE FOR
SUPERCELL STORM STRUCTURES CAPABLE OF LARGE HAIL AND DAMAGING WINDS.
NORTHWARD EXTENT OF SEVERE IS UNCERTAIN DUE TO MEAGER LOW LEVEL
MOISTURE. HOWEVER...STRONG KINEMATIC FIELDS EXTEND AS FAR NORTH AS
WESTERN NEB...SUGGESTING A RISK OF STRONG CELLS AND HAIL DURING THE
EVENING IF MARGINAL ELEVATED INSTABILITY CAN DEVELOP.

URGENT - IMMEDIATE BROADCAST REQUESTED
SEVERE THUNDERSTORM WATCH NUMBER 915
NWS STORM PREDICTION CENTER NORMAN OK
625 AM MST SAT OCT 11 2008

THE NWS STORM PREDICTION CENTER HAS ISSUED A
SEVERE THUNDERSTORM WATCH FOR PORTIONS OF

MUCH OF EASTERN ARIZONA
PARTS OF WESTERN NEW MEXICO

EFFECTIVE THIS SATURDAY MORNING AND AFTERNOON FROM 625 AM UNTIL
200 PM MST.

HAIL TO 2 INCHES 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 95
STATUTE MILES EAST AND WEST OF A LINE FROM 20 MILES SOUTHEAST OF
SIERRA VISTA ARIZONA TO 35 MILES NORTH NORTHWEST OF GALLUP NEW
MEXICO. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED
WATCH OUTLINE UPDATE (WOUS64 KWNS WOU5).

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...INTENSE SURFACE AND UPPER LOW OVER SRN INTERMOUNTAIN
REGION WITH RAPIDLY INCREASING MOISTURE/INSTABILITY SPREADING NEWD
ACROSS THE WATCH AREA. THUNDERSTORMS EXPECTED TO RAPIDLY INCREASE
IN NUMBER AND INTENSITY WITH STRONG SHEAR FAVORABLE FOR SUPERCELLS.
PRIMARY THREAT WILL BE LARGE HAIL AND DAMAGING WINDS WHICH WILL BE
ENHANCED BY THE VERY STRONG WIND PROFILES IN PLACE.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 60
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500. MEAN STORM
MOTION VECTOR 23040.

DRASTIC DIFFERENCES EVIDENT BY LATE IN THE DAY 6 PERIOD.

PRIOR TO THIS...A COLD FRONT MOVING EWD ACROSS THE ERN HALF OF THE
CONUS DAYS 4 AND 5 /TUE. AND WED. OCT. 14 AND 15/ SHOULD SERVE AS A
FOCUS FOR CONVECTIVE DEVELOPMENT...BUT MINIMAL INSTABILITY AT BEST
SHOULD PRECLUDE ANY SEVERE THREAT.

VALID 131200Z - 141200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE LARGE UPPER TROUGH EXTENDING FROM THE CANADIAN PRAIRIE SSWWD
INTO THE DESERT SW IS FORECAST TO SEPARATE INTO TWO DISTINCT
FEATURES THIS PERIOD -- THE NRN FEATURE MOVING EWD ACROSS THE
CANADIAN PRAIRIE/NRN PLAINS TOWARD THE UPPER GREAT LAKES...AND THE
SRN FEATURE LINGERING OVER THE SOUTHWEST AS AN INCREASINGLY-CUTOFF
LOW.

AT THE SURFACE...A COLD FRONT WILL CONTINUE MOVING EWD ACROSS THE
PLAINS/MS VALLEY...AND SEWD ACROSS THE SRN PLAINS THROUGH THE
PERIOD.

...PARTS OF E CENTRAL AND SERN NM AND ADJACENT PARTS OF W TX...
COMBINATION OF MARGINAL INSTABILITY AND MODEST SHEAR INVOF THE
TRAILING END OF THE SURFACE FRONTAL ZONE SHOULD SUPPORT SCATTERED
AFTERNOON STORM DEVELOPMENT -- PARTICULARLY TO THE COOL SIDE OF THE
BOUNDARY. WHILE OVERALL SEVERE THREAT APPEARS LIMITED ATTM GIVEN
MARGINAL ENVIRONMENT...A FEW STRONGER CELLS MAY PRODUCE
HAIL/LOCALLY-GUSTY WINDS DURING THE AFTERNOON/EARLY EVENING.
