...NO SVR TSTM AREAS FORECAST...

--- UPDATES ---
1630Z GEN TSTM LINES APPEAR TO REMAIN VALID BASED ON OBSERVATIONAL
TRENDS AND LIMITED UPDATES IN PROGNOSTIC GUIDANCE SINCE. AS
SUCH...NO SUBSTANTIAL ADJUSTMENTS CAN BE JUSTIFIED ATTM...AND SVR
POTENTIAL STILL APPEARS TOO SMALL/CONDITIONAL EVERYWHERE FOR AOA
5-PERCENT PROBABILITIES.

..EDWARDS.. 11/23/2009

.PREV DISCUSSION... /ISSUED 1023 AM CST MON NOV 23 2009/

...SYNOPSIS...
THE MAIN BELT OF THE WLYS WILL REMAIN OVER CANADA THIS PERIOD. IN
THE WEAKER SRN BRANCH...AMPLIFYING DISTURBANCE NOW OVER THE CNTRL
RCKYS SHOULD EVOLVE INTO A CLOSED LOW THAT SHOULD REACH NE KS BY 12Z
TUE. DOWNSTREAM IN THE SAME BRANCH OF FLOW...IMPULSE NOW OVER W TN
EXPECTED TO CONTINUE ENE INTO SW VA THIS EVE...AND OFF THE NJ CST
EARLY TUE.

AT THE SFC...COLD FRONT/LOW ASSOCIATED WITH RCKYS SYSTEM WILL BECOME
BETTER DEFINED THROUGH THE PERIOD...WITH SUBSTANTIAL ASCENT EXPECTED
OVER THE CNTRL PLNS/LWR MO VLY LATER TONIGHT/EARLY TUE. FARTHER
E...WEAK FRONT AND ASSOCIATED CIRCULATION CENTERS WILL LINGER OFF
THE NC CST TODAY. THE CIRCULATIONS LIKELY WILL EVOLVE INTO SINGLE
LOW OFF THE DELMARVA CST TONIGHT/EARLY TUE AS TN UPR SYSTEM
APPROACHES REGION.

...CNTRL PLNS/LWR MO VLY...
MID LVL LAPSE RATES WILL STEEPEN LATE THIS AFTN THROUGH TONIGHT
OVER PARTS OF KS/NEB...DOWNSTREAM FROM AMPLIFYING CNTRL RCKYS
TROUGH. MOISTURE WILL REMAIN LIMITED. BUT COMBINATION OF
STEEPENING LAPSE RATES WITH STRONG DCVA/WAA MAY SUPPORT SCTD AREAS
OF WEAK TSTMS TONIGHT/EARLY TUE FROM CNTRL KS INTO ERN NEB/NW MO AND
WRN IA.

...ERN U.S...
ISOLD TO WDLY SCTD TSTMS SHOULD PERSIST INVOF FRONT/LOW LVL
CIRCULATION CENTERS E OF THE NC OUTER BANKS. CURRENT CONDITIONS
/WITH NELY SFC WINDS AT HATTERAS/...AND LOW AMPLITUDE NATURE OF
UPSTREAM DISTURBANCE...SUGGEST THAT WARM SECTOR AIR MASS...AND ANY
ASSOCIATED POTENTIAL FOR SFC-BASED STORMS/SVR WEATHER...WILL REMAIN
OFFSHORE.

FARTHER S...WEAKENING FRONT STALLED OVER CNTRL FL...LOOSELY TIED TO
SYSTEM OFF THE NC CST...MAY PROVIDE SUFFICIENT LOW LVL CONVERGENCE
TO SUPPORT A FEW DIURNAL TSTMS IN MOIST/MODESTLY UNSTABLE
AIR...WHERE MLCAPE COULD REACH 1500 J/KG.

...SRN/CNTRL TX...
SLY FLOW/MOISTURE TRANSPORT WILL INCREASE OVER SRN/ERN TX
TONIGHT/EARLY TUE AS AMPLIFYING SYSTEM REACHES THE CNTRL PLNS.
GRADUAL REMOVAL OF EXISTING CIN...AND UPLIFT ALONG SFC COLD
FRONT...MAY SUPPORT ISOLD STORM DEVELOPMENT LATE IN THE PERIOD.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1130 AM CST MON NOV 23 2009

VALID 241200Z - 251200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
SERIES OF PROGRESSIVE SHORTWAVES WILL HELP TO SHIFT SYNOPTIC
TROUGHING EWD FROM HIGH PLAINS TOWARD MS VALLEY REGION THROUGH DAY-2
PERIOD. STG SHORTWAVE TROUGH -- NOW ANALYZED OVER FRONT/LARAMIE/BIG
HORN RANGES OF CO/WY -- IS FCST TO STRENGTHEN WITH 500 MB CLOSED LOW
DEVELOPING OVERNIGHT DAY-1 OVER KS. THIS LOW SHOULD MOVE ENEWD FROM
NRN MO TOWARD SRN LM AND WEAKEN SOMEWHAT DAY-2...AS UPSTREAM
PERTURBATION APCHS/INTENSIFIES. LATTER TROUGH -- NOW EVIDENT IN
MOISTURE CHANNEL IMAGERY APCHG BC COAST -- IS FCST TO MOVE THROUGH
LARGE SCALE RIDGE POSITION OVER WRN CANADA DAY-1...THEN TURN SEWD
ACROSS SWRN PORTIONS OF PRAIRIE PROVINCES AND NRN U.S. HIGH PLAINS
DAY-2. BY 25/12Z...THIS FEATURE SHOULD EVOLVE INTO CLOSED CYCLONE
WITHIN 500-300 MB LAYER...OVER ERN DAKOTAS AND WRN MN...WITH
POSITIVELY TILTED TROUGH SWWD ACROSS NEB.

AT SFC...LOW NOW EVIDENT OVER SWRN KS IS EXPECTED TO MOVE NEWD ALONG
BAROCLINIC ZONE TO VICINITY STJ BY START OF PERIOD...THEN DEEPEN
SLIGHTLY AND BECOME MORE CLOSELY COLLOCATED WITH LEADING MID-UPPER
PERTURBATION INVOF SRN LM. TRAILING COLD FRONT WILL MOVE EWD ACROSS
LOWER-MID MS VALLEY...AND SEWD FROM TX/LA ACROSS NWRN GULF.
MEANWHILE...OLDER FRONTAL ZONE ACROSS CENTRAL/SRN FL PENINSULA IS
EXPECTED TO DECELERATE...BECOMING MORE DIFFUSE WITH TIME THROUGHOUT
PERIOD.

...S TX...
ISOLATED TO WIDELY SCATTERED TSTMS ARE POSSIBLE...BEGINNING AT START
OF PERIOD AS CARRY-OVER FROM POTENTIAL DISCUSSED IN DAY-1 OUTLOOK.
REGIME SHOULD BE CHARACTERIZED BY STG LOW LEVEL WAA AND MOISTURE
TRANSPORT...WHICH WILL COMBINE WITH POCKETS OF ENHANCED SFC HEATING
TO DESTABILIZE PREFRONTAL BOUNDARY LAYER THROUGH MUCH OF AFTERNOON.
AS PREFRONTAL SFC DEW POINTS UPPER 60S F BECOME MORE COMMON...MLCAPE
MAY RISE INTO 2000-2500 J/KG RANGE IN AREAS OF RELATIVELY SUSTAINED
CLOUD BREAKS. FRONTAL LIFT IMPINGING ON THIS ALREADY WEAKLY CAPPED
AIR MASS SHOULD BOOST CONVECTIVE COVERAGE INTO SCATTERED-NUMEROUS
RANGES AS FRONT MOVES SWD/SEWD OVER THIS REGION. MAJOR LIMITING
FACTOR FOR ANY ORGANIZED SVR POTENTIAL WILL BE LACK OF SHEAR...WITH
WEAK LOW-MID LEVEL WINDS LIMITING BOTH HODOGRAPH SIZE AND BULK WIND
DIFFERENCE THROUGH DEEP-LAYER SAMPLES.

...NRN MO TO WI/IL BORDER REGION...
WIDELY SCATTERED AND SHALLOW TSTMS ARE POSSIBLE IN ZONE OF STRONG
DEEP-LAYER ASCENT...STEEPENING LOW-MID LEVEL LAPSE RATES
SUFFICIENTLY TO SUPPORT RELATIVELY UNCAPPED AND MRGL BUOYANCY.
MODIFIED FCST SOUNDINGS SUGGEST LOW LEVEL FRONTOGENETIC/CYCLOGENETIC
FORCING AND WEAK CINH WILL SUPPORT MLCAPE UP TO ABOUT 250 J/KG AND
MUCAPE APCHG 500 J/KG FOR REASONABLY PROGGED SFC TEMPS 50S F AND DEW
POINTS UPPER 40S. LACK OF MORE ROBUST SHEAR...LOW LEVEL THETAE AND
CAPE PRECLUDE SVR THREAT.

...CENTRAL/SRN FL...
ISOLATED TO WIDELY SCATTERED TSTMS WILL BE POSSIBLE WITHIN LOW-LEVEL
BAROCLINIC ZONE ACROSS THIS REGION...SUPPORTED BY WEAK FRONTAL
ASCENT...DIURNAL HEATING...AND SFC DEW POINTS UPPER 60S/LOW 70S F.
50-80 KT UPPER-LEVEL WINDS BENEATH SRN FRINGE OF SUBTROPICAL JET
BRANCH MAY AID IN STORM ORGANIZATION...ESPECIALLY INVOF E COAST
WHERE SLY AND ELY FLOW COMPONENTS MAY AID IN SHEAR THROUGH
CLOUD-BEARING LAYER. HOWEVER...SVR POTENTIAL APPEARS TOO
MRGL/CONDITIONAL FOR AOA 5-PERCENT PROBABILITIES ATTM.

NWS STORM PREDICTION CENTER NORMAN OK
1023 AM CST MON NOV 23 2009

VALID 231630Z - 241200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE MAIN BELT OF THE WLYS WILL REMAIN OVER CANADA THIS PERIOD. IN
THE WEAKER SRN BRANCH...AMPLIFYING DISTURBANCE NOW OVER THE CNTRL
RCKYS SHOULD EVOLVE INTO A CLOSED LOW THAT SHOULD REACH NE KS BY 12Z
TUE. DOWNSTREAM IN THE SAME BRANCH OF FLOW...IMPULSE NOW OVER W TN
EXPECTED TO CONTINUE ENE INTO SW VA THIS EVE...AND OFF THE NJ CST
EARLY TUE.

AT THE SFC...COLD FRONT/LOW ASSOCIATED WITH RCKYS SYSTEM WILL BECOME
BETTER DEFINED THROUGH THE PERIOD...WITH SUBSTANTIAL ASCENT EXPECTED
OVER THE CNTRL PLNS/LWR MO VLY LATER TONIGHT/EARLY TUE. FARTHER
E...WEAK FRONT AND ASSOCIATED CIRCULATION CENTERS WILL LINGER OFF
THE NC CST TODAY. THE CIRCULATIONS LIKELY WILL EVOLVE INTO SINGLE
LOW OFF THE DELMARVA CST TONIGHT/EARLY TUE AS TN UPR SYSTEM
APPROACHES REGION.

...CNTRL PLNS/LWR MO VLY...
MID LVL LAPSE RATES WILL STEEPEN LATE THIS AFTN THROUGH TONIGHT
OVER PARTS OF KS/NEB...DOWNSTREAM FROM AMPLIFYING CNTRL RCKYS
TROUGH. MOISTURE WILL REMAIN LIMITED. BUT COMBINATION OF
STEEPENING LAPSE RATES WITH STRONG DCVA/WAA MAY SUPPORT SCTD AREAS
OF WEAK TSTMS TONIGHT/EARLY TUE FROM CNTRL KS INTO ERN NEB/NW MO AND
WRN IA.

...ERN U.S...
ISOLD TO WDLY SCTD TSTMS SHOULD PERSIST INVOF FRONT/LOW LVL
CIRCULATION CENTERS E OF THE NC OUTER BANKS. CURRENT CONDITIONS
/WITH NELY SFC WINDS AT HATTERAS/...AND LOW AMPLITUDE NATURE OF
UPSTREAM DISTURBANCE...SUGGEST THAT WARM SECTOR AIR MASS...AND ANY
ASSOCIATED POTENTIAL FOR SFC-BASED STORMS/SVR WEATHER...WILL REMAIN
OFFSHORE.

FARTHER S...WEAKENING FRONT STALLED OVER CNTRL FL...LOOSELY TIED TO
SYSTEM OFF THE NC CST...MAY PROVIDE SUFFICIENT LOW LVL CONVERGENCE
TO SUPPORT A FEW DIURNAL TSTMS IN MOIST/MODESTLY UNSTABLE
AIR...WHERE MLCAPE COULD REACH 1500 J/KG.

...SRN/CNTRL TX...
SLY FLOW/MOISTURE TRANSPORT WILL INCREASE OVER SRN/ERN TX
TONIGHT/EARLY TUE AS AMPLIFYING SYSTEM REACHES THE CNTRL PLNS.
GRADUAL REMOVAL OF EXISTING CIN...AND UPLIFT ALONG SFC COLD
FRONT...MAY SUPPORT ISOLD STORM DEVELOPMENT LATE IN THE PERIOD.

...NO SVR TSTM AREAS FORECAST...

PRIMARY FEATURE OF INTEREST THIS FORECAST PERIOD IS THE VIGOROUS
COLD TROUGH TRANSLATING EWD FROM ROCKIES INTO THE CENTRAL PLAINS BY
TONIGHT. UPPER LOW DEVELOPS OVER KS PROVIDING STRONG ASCENT
DOWNSTREAM ALONG WITH RELATIVELY STEEP LAPSE RATES. LIMITED
MOISTURE/INSTABILITY PRECLUDES OTHER THAN WEAK THUNDERSTORMS TONIGHT
IN ADVANCE OF DEVELOPING UPPER LOW AND SURFACE CONVERGENCE WITH
ASSOCIATED SURFACE LOW AND COLD FRONT ERN KS/NE INTO NWRN MO AND WRN
IA.

WEAK FRONT STALLED ACROSS CENTRAL FL WILL PROVIDE SOME CONVERGENCE
TO TRIGGER A FEW AFTERNOON THUNDERSTORMS IN A MOIST AND MODESTLY
UNSTABLE AIR MASS WHERE MLCAPES S OF FRONT RISE TO 1500 J/KG.

...DISCUSSION...
PROGRESSIVE AND HIGH-AMPLITUDE FLOW REGIME WILL DOMINANT THE MEDIUM
RANGE. STRONG UPR TROUGH THAT EVOLVES OVER THE ERN HALF OF THE
COUNTRY WEDNESDAY AND THURSDAY WILL QUICKLY DEPART THE ERN SEABOARD
BY THE UPCOMING WEEKEND. BUILDING SFC HIGH PRESSURE WILL SEND A
CDFNT WELL S INTO THE SRN GULF OF MEXICO LATE IN THE WEEK. NEXT
SYSTEM IS FCST TO QUICKLY MOVE INTO THE NRN ROCKIES LATE FRIDAY AND
SATURDAY. SPREAD IN MODEL GUIDANCE BEGINS TO INCREASE OVER THE
WEEKEND...PRIMARILY IN HOW MUCH SRN STREAM ENERGY CAN BECOME
DETACHED FROM THE NRN STREAM UPR LOW. FAMILY OF ECMWF DETERMINISTIC
AND MEANS SUGGEST A SLOWER AND LESS AMPLIFIED SOLUTION...WHICH HAS
BEEN MORE CONSISTENT OVER THE PAST SVRL RUNS. IT IS REASONABLE TO
EXPECT AN INCREASE IN THE RETURN FLOW REGIME AHEAD OF THE TROUGH
OVER THE WEEKEND WITH AN INCREASE IN TSTM THREATS OVER PARTS OF THE
SRN PLNS EWD ACROSS THE GULF CSTL REGION BY EARLY NEXT WEEK. GULF
MOISTURE WILL MOST LIKELY BE OF ONLY MODEST QUALITY AND GIVEN
VARIABILITY IN MODELS IN HANDLING OF THE WEEKEND TROUGH...FCST
CONFIDENCE IN A SVR EPISODE IS NOT HIGH.

...SYNOPSIS...
LEAD UPR WAVE THAT WILL BE EJECTING ACROSS THE MIDWEST EARLY
WEDNESDAY WILL WEAKEN OVER THE GRTLKS REGION AS ANOTHER STRONG
IMPULSE DIGS INTO THE MID-MS VLY/UPR MIDWEST BY WEDNESDAY EVENING.
MEANWHILE...SUB-TROPICAL BRANCH WILL CARRY A DISTURBANCE ACROSS THE
GULF OF MEXICO TOWARD FL BY WEDNESDAY NIGHT.

AT THE SFC...INITIAL CDFNT ASSOCD WITH THE WEAKENING GRTLKS
DISTURBANCE WILL BECOME REINFORCED BY WEDNESDAY EVENING BY A
STRONGER FRONT. THIS NEW CP AIR MASS WILL REACH THE UPR OH/TN VLYS
AND CNTRL GULF CSTL REGION BY 12Z THURSDAY. MEANWHILE...AN OLD
FRONT WILL WAVE BACK N AS A WRMFNT INTO CNTRL FL AS A WAVE MIGRATES
EWD THROUGH THE CNTRL/ERN GULF BASIN. THIS LOW WILL TEND TO
REDEVELOP OFF THE ERN FL CST BY EARLY THURSDAY.

...CNTRL/SRN FL...
ONE OR MORE MCS/S WILL LIKELY BE ONGOING OVER THE CNTRL/ERN GULF OF
MEXICO AT THE START OF THE PD...LIKELY IN RESPONSE TO A SUBTROPICAL
JETLET. THESE STORMS ARE EXPECTED TO DEVELOP/MOVE ENE ALONG THE
FRONTAL ZONE INTO PENINSULAR FL DURING THE LATE AFTN/NIGHT. MODELS
INDICATE THAT LLVL MOISTURE...CHARACTERIZED BY 70S DEW POINTS...WILL
ADVECT NWD INTO AT LEAST CNTRL FL DURING THE LATE AFTN. LOW/MID-LVL
LAPSE RATES ARE EXPECTED TO REMAIN MODEST AT BEST...BUT GIVEN AN

DAY2SVR: Nws Storm Prediction Center Norman Ok

ACUS02 KWNS 230533
SWODY2
SPC AC 230532

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1132 PM CST SUN NOV 22 2009

VALID 241200Z - 251200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
STRONG UPR LOW OVER THE LWR MO VLY EARLY TUESDAY WILL TRANSLATE INTO
THE MIDWEST TUESDAY NIGHT AS ANOTHER IMPULSE DROPS SWD INTO THE NRN
PLNS. IN THE LWR LVLS...A LOW TIED TO THE FORMER SYSTEM WILL MOVE
FROM NWRN MO INTO WCNTRL IL BY 12Z WEDNESDAY AS A CDFNT SWEEPS EWD
THROUGH THE MIDWEST...OH/LWR MS VLYS AND THE WRN GULF OF MEXICO.
FARTHER S...AN OLD FRONT WILL CONTINUE SITUATED FROM PARTS OF
PENINSULAR FL WWD ACROSS THE CNTRL GULF OF MEXICO. A FRONTAL WAVE
WILL FORM ALONG THIS BOUNDARY OVER THE WRN GULF BY TUESDAY NIGHT IN
RESPONSE TO SRN STREAM ENERGY EJECTING NEWD FROM CNTRL MEXICO.

...CORN BELT/UPR MS VLY...
UPR LOW/PV-ANOMALY SHOULD PEAK IN INTENSITY DURING THE FIRST HALF OF
TUESDAY OVER PARTS OF IA/MO WITH UVV GRADUALLY WEAKENING DURING THE
NIGHT AS THE FEATURE BEGINS TO LIFT NEWD TOWARD THE UPR MS VLY.
FCST SOUNDINGS EXHIBIT SUFFICIENT MOISTENING/STEEP H7-H5 LAPSE RATES
FOR UPRIGHT ELEVATED CONVECTION...PARTICULARLY TUESDAY MORNING AND
AFTN FROM CNTRL/SRN IA AND NRN MO NEWD INTO PARTS OF WRN IL. MEAGER
THERMAL BUOYANCY WILL PRECLUDE SVR TSTMS.

...S TX...
CDFNT IS EXPECTED TO MOVE FROM NW-SE ACROSS S TX FROM MID-DAY INTO
THE LATE AFTN TUESDAY. PRE-FRONTAL WARM SECTOR WILL HAVE MOISTENED
BY THEN WITH SFC DEW POINTS IN THE 60S...RESULTING IN MLCAPES OF
1000-1500 J/KG. BUOYANCY WILL NOT BE PARTICULARLY ROBUST OWING TO
POOR LLVL LAPSE RATES EXPECTED. FURTHERMORE... GIVEN THAT THE
PRIMARY CORE OF MID/UPR-LVL WIND FIELDS IS PROGGED TO PASS THROUGH N
TX...THE DEEP LAYER SHEAR WILL BE WEAK...LESS THAN 30 KTS. AS
SUCH...SVR TSTM PROBABILITIES SHOULD REMAIN LOW.

...CNTRL FL...
A FEW TSTMS MAY BE POSSIBLE INVOF THE FRONTAL ZONE ACROSS CNTRL
FL...PRIMARILY TUESDAY AFTN/NIGHT. WHILE THE WARM MID-TROPOSPHERIC
TEMPERATURES WILL LIKELY CAP OFF STORMS EARLY IN THE DAY...APCH OF
THE H5 TROUGH/WEAK HEIGHT FALLS SHOULD CONTRIBUTE TO COOLING. THIS
WILL MAKE THERMODYNAMIC PROFILES MORE FAVORABLE FOR TSTMS LATER IN
THE DAY 2 PERIOD. NO SVR WEATHER IS ANTICIPATED.

DAY1SVR: Day 1 Convective Outlook

ACUS01 KWNS 230532
SWODY1
SPC AC 230530

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1130 PM CST SUN NOV 22 2009

VALID 231200Z - 241200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...

A BROAD...CYCLONIC FLOW REGIME WILL BE MAINTAINED OVER MUCH OF THE
CONUS THROUGH THE DAY ONE PERIOD. THE PRIMARY FEATURE OF INTEREST
WITHIN THIS LARGER-SCALE PATTERN IS SHORT WAVE TROUGH WHICH WILL
INTENSIFY AND EVOLVE INTO A CLOSED SYSTEM WHILE TRANSLATING SEWD
FROM THE GREAT BASIN AND NRN INTERMOUNTAIN REGION INTO THE CNTRL
CONUS. ELSEWHERE...VORTICITY MAXIMUM CURRENTLY OVER THE CNTRL
APPALACHIANS WILL CONTINUE NEWD TO OFF THE MID ATLANTIC COAST.

AT THE SURFACE...LOW PRESSURE INITIALLY OVER THE SRN HIGH PLAINS IS
FORECAST TO DEEPEN SLIGHTLY WHILE DEVELOPING NEWD INTO THE LOWER MO
VALLEY. MEANWHILE...TRAILING COLD FRONT WILL SURGE SWD THROUGH THE
CNTRL AND SRN PLAINS. FARTHER E...SURFACE LOW WILL DEVELOP NNEWD
JUST OFF THE ATLANTIC COAST IN CONJUNCTION WITH LATTER MIDLEVEL
SYSTEM MENTIONED ABOVE.

...NC OUTER BANKS...

TSTMS NOW ONGOING OFF THE SC COAST ARE EXPECTED TO MOVE/DEVELOP
NNEWD ACROSS AREA TODAY IN CONCERT WITH MIGRATORY SURFACE LOW.
WHILE SOME WEAK SURFACE-BASED DESTABILIZATION IS FORECAST ALONG THE
COAST...ANY SEVERE WEATHER THREAT SHOULD REMAIN OFFSHORE.

...FL...

SCATTERED...DIURNAL STORMS WILL BE POSSIBLE ALONG/S OF SURFACE FRONT
WHICH IS FORECAST TO STALL OVER THE CNTRL PENINSULA TODAY. WEAK
LAPSE RATES AND VERTICAL SHEAR WILL PRECLUDE ANY SEVERE WEATHER
POTENTIAL.

...MID MO VALLEY...

ISOLATED TSTM DEVELOPMENT WILL BE POSSIBLE ALONG SURFACE FRONT LATER
TODAY INTO TONIGHT AS HEIGHT FALLS/DYNAMIC COOLING EFFECTIVELY
STEEPEN LAPSE RATES AND CONTRIBUTE TO A SMALL AMOUNT OF CONVECTIVE
INSTABILITY.

...CNTRL/SRN TX...

A MODIFIED CONTINENTAL AIR MASS WILL RETURN NWD IN ADVANCE OF
SWD-MOVING COLD FRONT WITH DEWPOINTS INCREASING THROUGH THE 50S OVER
THE HILL COUNTRY...TO MID 60S OVER DEEP S TX. THIS MOISTURE
INCREASE COUPLED WITH STEEPENING LAPSE RATES AHEAD OF AMPLIFYING
UPPER SYSTEM WILL RESULT IN A WEAKLY UNSTABLE ENVIRONMENT...
SUPPORTIVE OF SCATTERED TSTM DEVELOPMENT LATE TONIGHT INTO TUESDAY
MORNING.
