DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0152 PM CST THU DEC 20 2007

VALID 202000Z - 211200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS CENTRAL GULF COAST
REGION...

..LOWER MS VALLEY TO CENTRAL/NERN GULF COAST REGION...
WATER VAPOR IMAGERY SHOWED A SHORT WAVE TROUGH MOVING EWD THROUGH
THE LOWER MS VALLEY. THIS SYSTEM WILL PROGRESS EWD THIS FORECAST
PERIOD...REACHING THE SERN STATES BY 12Z FRIDAY. EARLY AFTERNOON
SURFACE ANALYSES AND TRENDS IN REGIONAL RADAR DATA FROM LA EWD ALONG
THE CENTRAL GULF COAST AREA SUGGEST THE INITIAL MESOLOW THAT MOVED
EWD ACROSS SRN MS HAS OCCLUDED INTO A BROADER AREA OF CIRCULATION
NOW CENTERED OVER WEST CENTRAL AL. MEANWHILE...A SECOND MESOLOW HAS
OR IS EXPECTED TO DEVELOP CLOSER TO THE GULF COAST IN SERN MS...WITH
THIS LOW THEN TRACKING EWD THROUGH SWRN AL INTO THE FL PANHANDLE AND
NRN FL.

PRIOR TO SLY LLJ WEAKENING THIS EVENING...THIS FLOW IS EXPECTED TO
AID IN ADDITIONAL LOW LEVEL MOISTURE RETURN/DESTABILIZATION ACROSS
THE FL PANHANDLE INTO FAR SRN PARTS OF AL. ALTHOUGH INSTABILITY IS
EXPECTED TO REMAIN WEAK...ONGOING TSTMS /LINEAR STRUCTURES INLAND
AND SUPERCELL MODE CURRENTLY LOCATED OFFSHORE OF THE MS/AL COAST/
ARE EXPECTED TO PROGRESS EWD THROUGH SRN AL AND THE FL PANHANDLE.
EFFECTIVE BULK SHEAR AND STRONG LOW LEVEL SHEAR VALUES WILL MAINTAIN
POTENTIAL FOR ORGANIZED STORMS WITH A THREAT FOR DAMAGING WINDS AND
ISOLATED TORNADOES.

TSTMS MAY PERSIST EWD INTO PARTS OF THE SERN STATES TONIGHT...BUT
WEAKENING LLJ THIS EVENING AND GREATER FORCING FOR ASCENT MOVING
EAST OF BETTER INSTABILITY SUGGESTS SEVERE WEATHER THREAT SHOULD
DIMINISH THIS EVENING AS ACTIVITY MOVES INTO GA/NRN FL.

CONCERNING...TORNADO WATCH 741...

VALID 201906Z - 202030Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 741 CONTINUES.

A SEVERE THREAT WILL CONTINUE ACROSS WW 741 WITH THE GREATEST
POTENTIAL FOR SEVERE ACROSS THE SRN AND ERN PART OF THE WATCH. WIND
DAMAGE AND HAIL WILL BE POSSIBLE WITH THE STRONGER STORMS.

THE LATEST SFC ANALYSIS SHOWS A COLD FRONT ADVANCING EWD ACROSS FAR
SE TX AND WRN LA WITH SFC DEWPOINTS REMAINING IN THE 60S F ACROSS
SRN LA AND FAR SRN MS. SFC WINDS HAVE VEERED ACROSS SOUTHWEST LA AND
A DRY SLOT ASSOCIATED WITH AN APPROACHING UPPER-LEVEL TROUGH HAS
ENDED THE SEVERE THREAT THERE. FARTHER EAST ACROSS SE LA...SFC WINDS
REMAIN SLY AND OBJECTIVE ANALYSIS SUGGESTS MUCAPE VALUES OF 500 TO
1000 J/KG STILL EXIST IN THE NEW ORLEANS AREA. IN ADDITION...STRONG
VERTICAL SHEAR IS PRESENT EVIDENT ON SEVERAL REGIONAL WSR-88D VWPS
WHICH COMBINED WITH STEEPENING MID-LEVEL LAPSE RATES AS THE
UPPER-LEVEL TROUGH APPROACHES SHOULD CONTINUE TO PROMOTE AN ISOLATED
SEVERE THREAT THIS AFTERNOON.

CONCERNING...TORNADO WATCH 742...743...

VALID 201903Z - 202000Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 742...743...CONTINUES.

GREATEST SEVERE THREAT...THE NEXT HOUR OR SO...WILL BE ACROSS SWRN
AL AND THE FAR WRN FL PANHANDLE.

AT 1850Z...AN MCV/POSSIBLE MESOLOW WAS LOCATED ABOUT 70 ESE OF MEI.
THIS CIRCULATION AND ASSOCIATED REAR INFLOW JET HAVE WEAKENED AS THE
SYSTEM HAS MOVED INTO WEAKER INSTABILITY. HOWEVER...CONVECTION
CONTINUES FROM THE MESOLOW SWWD INTO EXTREME SWRN AL AND FAR SERN
MS. A BOUNDARY ALSO EXTENDED FROM THE NORTH CENTRAL GULF NWD INTO
FAR SWRN AL. AT THE INTERSECTION OF THE THUNDERSTORM LINE AND
BOUNDARY...AND GIVEN THE STRONG DEEP LAYER SHEAR...THE POTENTIAL
EXISTS FOR ANOTHER WEAK CIRCULATION TO DEVELOP ALONG THIS LINE.
SPORADIC WIND DAMAGE IS EXPECTED WITH THE LINE AS IT SHIFTS
ESEWD...BUT THE THREAT FOR WIND DAMAGE WOULD INCREASE IF ANOTHER MID
LEVEL CIRCULATION DEVELOPS ALONG THE BOUNDARY.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1123 AM CST THU DEC 20 2007

VALID 211200Z - 221200Z

..NO SVR TSTM AREAS FORECAST...

..SYNOPSIS AND FORECAST...
PROGRESSIVE UPPER LEVEL FLOW PATTERN WILL PERSIST INTO THE DAY 2
PERIOD ACROSS THE CONUS. A PAIR OF SHORT WAVE TROUGHS...ONE
CURRENTLY LOCATED IN BC AND THE SECOND DIGGING SEWD ACROSS NRN CA...
ARE BOTH EXPECTED TO REMAIN GENERALLY PHASED AND AMPLIFY AS THEY
TRACK SEWD INTO THE PLAINS STATES BY END OF DAY 2. ATTENDANT
PACIFIC COLD FRONT IS FORECAST TO MOVE OUT OF THE ROCKIES THROUGH
THE PLAINS REGION ON FRIDAY...AND SHOULD EXTEND FROM THE UPPER MS
VALLEY SWWD THROUGH LOWER MO VALLEY TO CENTRAL/ERN OK AND W TX BY
12Z SATURDAY. SLY LLJ IS EXPECTED TO STRENGTHEN FROM THE SRN PLAINS
TO MID MO VALLEY REGION FRIDAY IN RESPONSE TO HEIGHT FALLS AHEAD OF
APPROACHING UPPER TROUGHS. MODELS SUGGEST LOW LEVEL MOISTURE RETURN
SHOULD DEVELOP LATE IN THE FORECAST PERIOD. PRESENT INDICATIONS
SUGGEST LOW LEVEL WAA AND SOME INCREASE IN LARGE SCALE ASCENT AHEAD
OF THE SRN TROUGH MAY ALLOW A FEW TSTMS TO DEVELOP AFTER 22/09Z
WITHIN AXIS OF MOIST RETURN FLOW MAINLY ACROSS E TX. LACK OF STRONG
FORCING...PRESENCE OF CAPPING INVERSION AND WEAK INSTABILITY SHOULD
PRECLUDE ANY SEVERE WEATHER THREAT.

FARTHER E...LOWER MS VALLEY SHORT WAVE TROUGH SHOULD BE LOCATED OVER
THE SERN STATES AT 12Z FRIDAY AND WILL UNDERGO FURTHER WEAKENING AS
THIS SYSTEM MOVES OFF THE SRN ATLANTIC COAST FRIDAY MORNING.
ATTENDANT SURFACE LOW FORECAST TO BE CENTERED IN NRN FL/ SRN GA AT
START OF PERIOD WILL ALSO MOVE OFFSHORE WITH THE UPPER TROUGH.
TSTMS MAY BE ONGOING ACROSS PARTS OF SERN GA INTO NRN/WRN FL WITH
ACTIVITY LIKELY WEAKENING AS LOW LEVEL CONVERGENCE WEAKENS IN
RESPONSE TO GREATER FORCING MOVING EAST OF THE REGION EARLY. WEAK
INSTABILITY IS EXPECTED TO LIMIT ANY SEVERE WEATHER THREAT.

CONCERNING...TORNADO WATCH 741...742...

VALID 201721Z - 201845Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 741...742...CONTINUES.

AN ISOLATED TORNADO THREAT AND WIND DAMAGE POTENTIAL WILL EXIST
ACROSS SRN LA AND SRN MS MOVING EWD INTO SRN AL EARLY THIS
AFTERNOON. THE GREATEST THREAT SHOULD EXIST IN THE ERN PARTS OF WW
741 AND WW 742. A NEW WW MAY BE NEEDED EAST OF WW 742 BY LATE THIS
AFTERNOON.

THE LATEST RADAR IMAGERY CONTINUES TO SHOW A PERSISTENT BOW ECHO IN
SRN MS ACROSS WW 742 WITH LESS ORGANIZED CONVECTION EXTENDING WSWWD
ACROSS NRN AND WRN WW 741. WATER VAPOR IMAGERY SHOWS A WELL-DEFINED
UPPER-LEVEL TROUGH OVER ERN AR EXTENDING SWD ACROSS SW LA. A 60 KT
JET NEAR 700 MB ASSOCIATED WITH THE SHORTWAVE TROUGH IS LOCATED IN
CNTRL LA INTO SW MS AND IS LIKELY HELPING TO SUPPORT THE BOW ECHO IN
SRN MS. THE BOW ECHO SHOULD BEGIN TO TURN SEWD FAVORING THE GREATER
INSTABILITY AND HIGHER LOW-LEVEL MOISTURE NORTH OF MOBILE AL AND
ALONG THE I-10 CORRIDOR IN THE WRN FL PANHANDLE. A TORNADO OR TWO
ALONG WITH WIND DAMAGE WILL CONTINUE TO BE POSSIBLE WITH THE BOW
INTO EARLY THIS AFTERNOON.

FURTHER WEST ACROSS THE SRN PORTION OF WW 741...REGIONAL WSR-88D
VWPS SHOW STRONG DIRECTIONAL SHEAR AND FAVORABLE SPEED SHEAR FOR
ROTATING STORMS. IN ADDITION...THE LATEST OBJECTIVE ANALYSIS SHOWS
MORE INSTABILITY /SBCAPE VALUES AROUND 800 J/KG/ IS LOCATED ACROSS
SRN LA SUGGESTING THE THREAT FOR SEVERE WILL CONTINUE THIS
AFTERNOON.

..THE LOWER MS VALLEY/CENTRAL GULF COASTAL REGION...
AT MID MORNING...MID LEVEL SHORTWAVE EXTENDED FROM CENTRAL AR SWWD
INTO FAR SWRN LA...AND WILL PROGRESS EWD ACROSS THE CENTRAL GULF
COAST STATES THIS AFTERNOON AND INTO THE NERN GULF COAST REGION
TONIGHT. IN ASSOCIATION WITH THIS UPPER TROUGH...A MEOSLOW WAS
LOCATED IN SERN MS...WITH A TRAILING BOUNDARY/CONVECTION EXTENDING
SWWD INTO FAR SWRN LA. DESPITE RICHER BOUNDARY LATER
MOISTURE/INSTABILITY TO THE WEST OF THE ONGOING THUNDERSTORMS...
STRONGER FORCING AND 50-60 KT DEEP LAYER SHEAR WILL SUPPORT A THREAT
OF SEVERE STORMS WITH THIS CONVECTION. THE PRESENCE OF THE EWD
MOVING MESOLOW AND 1 KM SHEAR AT 30KT WILL BE FAVORABLE FOR A FEW
TORNADOES AND WIND DAMAGE INTO THIS AFTERNOON ACROSS SRN MS/SRN LA
AND SWRN AL AND POSSIBLY INTO THE FL PANHANDLE BY EVENING.

ALTHOUGH STRONGER INSTABILITY IS FORECAST TO SPREAD EWD INTO AR/LA
DURING THE AFTERNOON...CURRENT THINKING IS STRONG SUBSIDENCE BEHIND
ONGOING CONVECTION WILL LIMIT STRONG CONVECTIVE REDEVELOPMENT.

AREAS AFFECTED...UPR TX COAST...SABINE RVR VLY...SWRN LA

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 200930Z - 201100Z

A WEAK LEAD MID-LEVEL WAVE WAS EVIDENT IN WATER VAPOR IMAGERY
EJECTING NEWD AHEAD OF THE PARENT SRN PLAINS IMPULSE. THIS FEATURE
WILL CONTINUE ENEWD INTO THE AR OZARKS THROUGH 12Z. ATTENDANT 1011
MB SFC LOW WAS LOCATED OVER ECNTRL TX WITH TEMPORAL VEERING OF THE
LOW/MID-LVL WIND PROFILES SWWD IN AREAS EAST OF THE ESCARPMENT. THE
LOW WILL LIKELY RECONSOLIDATE OVER THE ARKLATEX BY 12Z WHERE CURRENT
MAX IN PRESSURE FALLS ARE LOCATED. AS THIS OCCURS...MID-UPR 60S SFC
DEW POINTS WILL SURGE NWD ALONG THE UPR TX COAST INTO THE SABINE VLY
AND SWRN LA THE NEXT SEVERAL HOURS AS THE CORE OF THE LLJ FOCUSES
FROM NEAR/E OF HOUSTON NEWD INTO THE MID-SOUTH.

CURRENT TSTMS DEVELOPING VCNTY KLFK SEEM TO BE LOCATED ALONG THE NWD
MOVING WARM FRONT AND MAY BE ROOTED SUFFICIENTLY CLOSE TO THE SFC TO
ATTAIN MAXIMUM SRH IN AN ENVIRONMENT CHARACTERIZED BY MODEST VEERING
FROM SFC THROUGH 3 KM. THIS KINEMATIC ENVIRONMENT APPEARS TO BE
LIMITED TEMPORALLY AND SPATIALLY AS THE LOW/MID-LVL FLOW CONTINUES
TO VEER WITH TIME THROUGH DAYBREAK. THUS...ANY TORNADO THREAT WILL
LIKELY BE LIMITED TO THE SABINE RVR VLY.

OTHERWISE...DEEP LAYER SHEAR WILL REMAIN SUFFICIENT FOR OTHER
ELEVATED STORMS TO ATTAIN SUPERCELLULAR CHARACTERISTICS OVER THE
REMAINDER OF ERN TX AND CNTRL/NRN LA. THESE STORMS WILL LIKELY BE
MAINLY A LARGE HAIL THREAT. BUT...STORMS THROUGH CNTRL LA MAY
PRODUCE DMGG WIND GUSTS AS THE WARMER BOUNDARY LAYER WORKS NWD WITH

STRONG TROUGHING OVER CENTRAL CONUS -- PER LATEST DAY-3 OUTLOOK --
IS EXPECTED TO DEAMPLIFY THEREAFTER WITH CONSOLIDATED NRN STREAM LOW
MOVING EWD OVER GREAT LAKES. ASSOCIATED STRONG COLD FRONT IS FCST
TO SWEEP ACROSS MOST OF GULF...FOLLOWED BY CONTINENTAL ANTICYCLONE
THAT RENDERS AIR MASS TOO STABLE FOR ORGANIZED SVR THREAT FOR
SEVERAL MORE DAYS. MOST MREF MEMBERS...AS WELL AS OPERATIONAL
SPECTRAL AND ECMWF...FOLLOW THAT SYSTEM WITH SERIES OF WELL-DEFINED
BUT RATHER FAST MOVING SHORTWAVES IN NWLY-WNWLY FLOW...ON TRACK
ROUGHLY FROM PACIFIC NW TO S-CENTRAL/SWRN CONUS. LARGE
DISCREPANCIES IN PROGGED SFC FRONTAL/CYCLOGENETIC PROCESSES WITH
THESE SYSTEMS...AND RELATED CONCERNS ABOUT RETURN FLOW

NWS STORM PREDICTION CENTER NORMAN OK
0130 AM CST THU DEC 20 2007

VALID 221200Z - 231200Z

..NO SVR TSTM AREAS FORECAST...

..SYNOPSIS...
SEVERAL SHORTWAVE PERTURBATIONS NOW DISTRIBUTED FROM OFFSHORE NRN CA
TO NWRN BC ATTM SHOULD DIG SEWD AND LEAD TO SYNOPTIC SCALE TROUGHING
BY DAY-2 OVER WRN CONUS. EMBEDDED/NRN LOW IS EXPECTED TO DEVELOP
AND MOVE SEWD ACROSS NRN PLAINS. SRN WAVE IS EXPECTED TO PIVOT
CYCLONICALLY THROUGH BASE OF SYNOPTIC TROUGH LATE DAY-2 AND EARLY
DAY-3 BEFORE EJECTING NEWD TOWARD GREAT LAKES...HOWEVER CONSIDERABLE
DIFFERENCES ARE EVIDENT IN TIMING/GEOMETRY OF THIS PROCESS BY
22/18Z-23/00Z TIME FRAME. OPERATIONAL NAM-WRF...AS WELL AS MOST
ETA-BASED SREF MEMBERS...INDICATE MORE SWD TRACK OF NRN STREAM
LOW...LEADING TO FASTER...MORE COMPACT AND MORE NEGATIVELY TILTED
SRN PERTURBATION LIFTING NEWD FROM ARKLATEX IN 22/18Z-23/00Z TIME
FRAME.

BY CONTRAST...SPECTRAL/UKMET/ECMWF AND MOST RSM/WRF ENSEMBLE MEMBERS
ARE IN CLOSE AGREEMENT WITH MORE POSITIVE TILT AND SLOWER EJECTION
OF SRN WAVE BY 23/00Z. ALTHOUGH WE ARE LEANING TOWARD LATTER
SOLUTION GIVEN MORE UNRELIABLE HISTORY OF HANDLING SHORTWAVE PHASING
PROBLEMS IN NAM...THIS DISPARITY LOWERS CONFIDENCE IN SHORTWAVE
SCENARIO...AND IN RESULTING LOW LEVEL FEATURES...ESPECIALLY FROM
ABOUT 22/18Z ONWARD. IN GENERAL...STRONG SFC COLD FRONT SHOULD MOVE
EWD ACROSS MS VALLEY AND SEWD INTO NWRN GULF DURING THIS PERIOD.
CONSIDERABLE TIMING DIFFERENCES ARE EVIDENT WITH FROPA. MORE
PROGRESSIVE/WELL-PHASED MODELS PREDICT FASTER FRONTAL MOVEMENT...AND
MORE NUMEROUS/SLOWER PROGS WITH SRN MIDLEVEL WAVE ACCORDINGLY
RESPOND WITH SLOWER FRONT AND BETTER DEFINED CYCLONE LIFTING NEWD
FROM ARKLATEX TO MID MS VALLEY.

..WRN GULF COASTAL PLAIN TO MS DELTA REGION...
THOUGH ACHIEVED IN SOMEWHAT DIFFERENT WAYS...STRONG CONSENSUS AMONG
SREF AND OPERATIONAL GUIDANCE IS FOR FAVORABLE VERTICAL SHEAR TO
OVERSPREAD MUCH OF PREFRONTAL SECTOR DURING THIS PERIOD.
HOWEVER...THERMODYNAMIC UNCERTAINTIES -- BOTH SFC AND ALOFT --
PRECLUDE MORE THAN MRGL UNCONDITIONAL SVR PROBABILITIES ATTM.
DIFFERENT POSSIBILITIES FOR PHASING OF NRN/SRN WAVES CASCADES
DOWNSCALE THROUGH STRENGTH/GEOMETRY OF SFC ISOBARIC/ISALLOBARIC
PATTERNS...BOUNDARY LAYER KINEMATIC FIELDS/TRAJECTORIES...AND
THEREFORE...DISTRIBUTION OF FAVORABLE LOW LEVEL MOISTURE INLAND.

WITHOUT STRONG FROPA FOLLOWING CURRENT GULF COAST SYSTEM...RICHEST
SFC MOISTURE SHOULD REMAIN OVER W-CENTRAL OPEN GULF. HOWEVER...ELY
COMPONENT OF TRAJECTORIES OVER SERN CONUS...FL AND NERN GULF MAY
PERSIST LONG ENOUGH TO LIMIT INLAND EXTENT OF RICH MOISTURE RETURN.
MOST BULLISH MOISTENING SCENARIO ACTUALLY APPEARS IN SPECTRAL
INSTEAD OF NAM...WHICH IS RATHER ANOMALOUS. EVEN THEN...STRONGEST
ASCENT ALOFT REMAINS HORIZONTALLY DISPLACED FROM MOST FAVORABLE
MOISTURE. WHILE TSTMS ARE EXPECTED ALONG/AHEAD OF FRONT...CONCERNS
REMAIN ABOUT DISTRIBUTION OF SFC-BASED VERSUS ELEVATED CONVECTION IN
THIS REGIME...AND IMPACT OF INLAND CLOUDS/PRECIP ON DIURNAL
DESTABILIZATION AND MOISTURE RETURN.

VALID 211200Z - 221200Z

..NO SVR TSTM AREAS FORECAST...

CORRECTED FOR MISSING GEN TSTM LINES

..SYNOPSIS...
PROGRESSIVE UPPER AIR PATTERN FCST TO CONTINUE OVER CONUS THROUGH
THIS PERIOD. SHORTWAVE TROUGH NOW OVER SRN PLAINS IS EXPECTED TO
MOVE ESEWD ACROSS SERN CONUS...MOVING OFFSHORE SC/GA/ERN FL DURING
BEFORE 21/18Z. ASSOCIATED SFC LOW WILL BE CLOSE TO COAST ALONG
FRONTAL ZONE THAT WILL DEMARCATE NELY FLOW AND COLD/DAMMING REGIME
TO N FROM MOIST BOUNDARY LAYER OF GULF ORIGIN TO S. PRIND BUOYANCY
WILL BE TOO LIMITED TO SUPPORT ORGANIZED SVR POTENTIAL OVER LAND
WITH THIS DEPARTING SYSTEM...BUT MAY SUPPORT GEN TSTM POTENTIAL FOR
FIRST FEW HOURS.

MOST RELEVANT PERTURBATIONS ARE INDICATED OVER MOISTURE CHANNEL
IMAGERY ATTM OFFSHORE NRN CA/ORE...AND OVER AK PANHANDLE/NWRN BC
REGION. AS PHASING/INTENSIFICATION OF EACH OF THESE SHORTWAVES
OCCURS...HIGH-AMPLITUDE/SYNOPTIC-SCALE TROUGH IS FCST TO DEVELOP
ACROSS WRN THEN CENTRAL CONUS EARLY THIS PERIOD. BY 22/12Z...NRN
SHORTWAVE SHOULD EVOLVE INTO CLOSED LOW OVER ND OR ADJACENT PORTIONS
SASK/MB. MEANWHILE SRN TROUGH ALSO MAY EVOLVE INTO 500 MB LOW
ACROSS NM AND W TX DURING 22/00Z-22/12Z TIME FRAME...WITH 80-90 KT
500 MB FLOW TO ITS S ACROSS SRN NM AND W TX...AND 100-120 KT 250 MB
JET MAX. AT SFC...COLD FRONT IS FCST TO INTENSIFY AS IT MOVES OUT
OF ROCKIES...BEFORE SWEEPING EWD ACROSS NRN PLAINS/UPPER MS
VALLEY...AND SEWD OVER MOST OF TX/OK.

SFC LOW SHOULD FORM OVER SRN HIGH PLAINS ALONG FRONT...AND IN
ADVANCE OF SRN MIDLEVEL TROUGH...HOWEVER CONSIDERABLE VARIATION
EXISTS AMONG SREF AND OPERATIONAL GUIDANCE PACKAGES ON ITS STRENGTH
AND SPEED OF ITS NEWD EJECTION ALONG FRONT. PREFRONTAL DRYLINE AND
WIND SHIFT LINE SHOULD EXTEND SWD ACROSS CENTRAL OR ERN TX BY END OF
PERIOD...MARKING WRN BOUND OF CONVECTIVE THREAT ACROSS TX.

..SE TX...ARKLATEX TO SRN OZARKS...
VERY CONDITIONAL SVR POTENTIAL EXISTS NEAR END OF DAY-2
PERIOD...22/09Z AND BEYOND...WHICH REPRESENTS SPATIAL OVERLAP OF TWO
REGIMES...

1. COLD FRONT BEGINNING TO IMPINGE ON NWRN PORTION OF INCREASINGLY
MOIST RETURN FLOW...BUT WITH HIGHLY VARIABLE PROGS OF ACTUAL
BOUNDARY LAYER MOISTURE CONTENT.
2. FREE WARM SECTOR AHEAD OF FRONT...PARTICULARLY NEAR UPPER TX
COAST AND ADJACENT PORTIONS SE TX...WHERE SFC THETAE MAY BECOME HIGH
ENOUGH TO SUPPORT SFC-BASED EFFECTIVE LIFTED PARCELS.

MAIN UNCERTAINTY FOR BOTH REGIMES INVOLVES MAGNITUDE OF MOISTURE AND
RESULTANT LOW LEVEL DESTABILIZATION WITHIN RETURNING GULF AIR MASS.
LONG-FETCH SLY TRAJECTORIES -- ROOTED IN WRN OPEN GULF AND BAY OF
CAMPECHE -- REASONABLY ARE APPARENT IN MANY PROGS BY END OF
PERIOD...E OF DRYLINE/WIND SHIFT. HOWEVER...OPERATIONAL
WRF/SPECTRAL AND MOST SREF MEMBERS DO NOT RETURN SFC DEW POINTS 60 F
OR HIGHER FARTHER INLAND THAN ROUGHLY CLL-LFK-POE. SEVERAL SREF
OUTLIERS MAY BE MORE REASONABLE IN THIS SCENARIO...GIVEN LACK OF
INTENSE/COLD FROPA DEEP INTO GULF WITH PRECEDING SYSTEM. VERTICAL
SHEAR WILL BE STRENGTHENING AND FAVORABLE FOR ORGANIZED SVR DURING
OVERNIGHT HOURS AS SRN WAVE APCHS. HOWEVER...GIVEN UNCERTAINTIES
OVER MOISTURE RETURN...AND OVER TIMING OF CONVECTIVE INITIATION NEAR
END OF PERIOD...WILL DEPICT ONLY MRGL PROBABILITIES ATTM.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1137 PM CST WED DEC 19 2007

VALID 201200Z - 211200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE CENTRAL
GULF STATES...

..GULF COAST...

LATE EVENING WV IMAGERY SUPPORTS 00Z MODEL GUIDANCE REGARDING THE
POSITION/MOVEMENT OF SRN STREAM UPPER SHORTWAVE TROUGH. TROUGH AXIS
IS VERY NEAR THE NM/TX BORDER ATTM AND THIS FEATURE SHOULD MOVE
ACROSS TX THROUGH THE GULF COAST STATES INTO SRN GA BY THE END OF
THE PERIOD. WARM ADVECTION CONVECTION HAS RECENTLY DEVELOPED
DOWNSTREAM ACROSS SERN TX INTO SRN AR AS LLJ INCREASES ACROSS THIS
REGION. LATEST THINKING IS MODIFIED GULF AIRMASS WILL RETURN INLAND
ACROSS THE LOWER MS VALLEY THIS MORNING WITH 60S DEW POINTS EXPECTED
AS FAR NORTH AS PORTIONS OF SCNTRL AR BY SUNRISE. BOUNDARY LAYER
RECOVERY WILL PROVE INSTRUMENTAL IN DESTABILIZATION NECESSARY FOR
UPWARD GROWTH OF THUNDERSTORM CLUSTERS...LIKELY EVOLVING INTO AN MCS
OVER MS/AL AS LLJ VEERS TO A MORE WLY DIRECTION DURING THE DAYLIGHT
HOURS. AT THIS TIME IT APPEARS WARM ADVECTION WILL BE THE PRIMARY
DRIVING MECHANISM FOR DEEP CONVECTION ALONG SLOWLY RETREATING WARM
FRONT. IN THE WAKE OF THIS ACTIVITY LAPSE RATES WILL STEEPEN
SIGNIFICANTLY AS WLY FLOW DEEPENS THROUGH MID LEVELS. IT/S NOT
ENTIRELY CLEAR BASED ON THE AFOREMENTIONED CONVECTIVE SCENARIO
WHETHER SUFFICIENT CONVERGENCE WILL EXIST WITHIN STEEPER LAPSE
RATE/HIGHER INSTABILITY AIRMASS FOR MORE THAN ISOLATED THUNDERSTORM
DEVELOPMENT. IF ROBUST THUNDERSTORM ACTIVITY DOES EVOLVE IT MAY DO
SO ALONG LINGERING CONVECTIVE OUTFLOW BOUNDARIES...MOST LIKELY
ORIENTED IN AN E-W FASHION NEAR THE GULF COAST FROM SRN LA INTO SRN
MS. LARGE HAIL AND DAMAGING WINDS ARE THE PRIMARY SEVERE THREATS
GIVEN THE EXPECTED CLUSTERING NATURE AND THE LIKELIHOOD FOR MOST
CONVECTION TO OCCUR WITHIN WEAKER LAPSE RATE/INSTABILITY REGIME
ALONG RETREATING WARM FRONT. HOWEVER...SUFFICIENT SPEED SHEAR WILL
EXIST WITHIN MORE BUOYANT VEERED BOUNDARY LAYER FOR ROBUST ROTATING
UPDRAFTS IF MESOSCALE BOUNDARIES CAN SURVIVE INTO THE MID AFTERNOON
HOURS.

AREAS AFFECTED...NRN/CNTRL SIERRA MTNS OF CA

CONCERNING...HEAVY SNOW

VALID 200534Z - 200930Z

HEAVY SNOW WILL GRADUALLY SHIFT SWD OVERNIGHT WITH SNOWFALL RATES OF
1.5 TO 2 IN/HR LIKELY...MAINLY ABOVE 4000 FT THROUGH 12Z.

RECENT SATELLITE IMAGERY DEPICTS A SIGNIFICANT SHORT WAVE TROUGH
IMPINGING UPON THE NRN CA COAST. STRONG FORCED ASCENT AHEAD OF THIS
WAVE ALONG WITH SUBSTANTIAL LOW-LEVEL WARM/MOIST ADVECTION /INFERRED
FROM AREA VAD PROFILERS/ HAS AIDED IN POCKETS OF MODERATE RAINFALL
IN LOWER ELEVATIONS AND HEAVY SNOW IN HIGHER ELEVATIONS OF NRN CA.
AS MID-LEVEL COOLING INCREASES INVOF TROUGH AXIS...STEEPENING LAPSE
RATES WILL SUPPORT SHALLOW CONVECTION AND SHOULD HELP MAXIMIZE
SNOWFALL RATES ACROSS THE NRN/CNTRL SIERRA MTNS FROM 09-12Z GIVEN
CONTINUED FAVORABLE OROGRAPHIC ENHANCEMENT. TOWARDS 12Z...SNOWFALL
RATES SHOULD DIMINISH ACROSS THE NRN SIERRAS AS LOW/MID-LEVEL FLOW
WEAKENS AND VEERS. THIS IS CONSISTENT WITH LATEST MODEL GUIDANCE
INDICATING THE BULK OF HEAVIER QPF SHIFTING SWD EARLY THU MORNING.
