NWS Fort Worth, TX wrote its last area forecast discussion before the first event at May 6, 2:56 PM CST, 1 hour 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 356 PM CDT SUN MAY 6 2012 .DISCUSSION... THIS AFTERNOON THROUGH TONIGHT...THERE ARE NO SIGNIFICANT CHANGES IN THUNDERSTORM CHANCES THROUGH THE PERIOD AND THE EARLY AFTERNOON UPDATE DISCUSSION HAS BEEN ATTACHED THAT DETAILS THOUGHTS ON THIS PERIOD. ONLY UPDATE WAS TO EXTEND 20 POPS FOR LATE THIS AFTERNOON ALONG THE ENTIRE WESTERN CWA DUE TO A DEVELOPING CUMULUS FIELD. THINKING CONTINUES TO BE THAT IF A LINEAR MCS DEVELOPS IT WILL START NEAR THE COLD FRONT IN THE NORTHWESTERN CWA AROUND 00Z. DEW POINTS HAVE BEEN SLOWLY RECOVERING OUT AHEAD OF THE FRONT...HOWEVER CONVECTIVE INHIBITION REMAINS HIGH AS OF 21Z. WILL CONTINUE TO MONITOR THE THERMODYNAMIC ENVIRONMENT LATE THIS AFTERNOON AND PROVIDE FORECAST UPDATES AS NEEDED. MONDAY AND TUESDAY...THE COLD FRONT NEAR WICHITA FALLS LATE THIS AFTERNOON IS EXPECTED TO CONTINUE SOUTHEAST THROUGH MOST OF NORTH TX BY LATE MONDAY MORNING. THE SOMEWHAT SHALLOW FRONT WILL ALLOW FOR ELEVATED SHOWER AND THUNDERSTORM CHANCES TO PERSIST OVER NORTH TX THROUGH THE PERIOD. OUR BEST CHANCE FOR PRECIPITATION CONTINUES TO LOOK AS THOUGH IT WILL BE ASSOCIATED WITH A SHORTWAVE TROUGH MOVING UP OVER NORTH TX MONDAY NIGHT. DID NOT MAKE ANY SIGNIFICANT CHANGES TO THE PREVIOUS FORECAST DURING THE PERIOD. HAVE BEST POPS MOVING IN FROM THE SOUTHWEST AND TRANSLATING NORTHEAST OVER THE CWA THROUGH TUESDAY MORNING. ANOTHER CHANCE FOR STORMS WILL OCCUR WITH ANY WELL ORGANIZED MCS ACTIVITY THAT INITIATES ALONG THE HIGH PLAINS MONDAY NIGHT AND HOLDS TOGETHER AS IT MOVES EAST TOWARDS NORTH TX ON TUESDAY. DO NOT ANTICIPATE MUCH IN THE WAY OF SEVERE WEATHER...HOWEVER IT WOULD BE HARD TO RULE OUT AN ELEVATED STRONG STORM CAPABLE OF PRODUCING LARGE HAIL AS THE SHORTWAVE TROUGH MOVES OVER THE AREA. MOST OF THE STRONG INSTABILITY IS EXPECTED TO REMAIN SOUTH AND EAST OF THE LEADING EDGE OF THE COLD FRONT WHICH IS EXPECTED TO BE JUST SOUTH OF THE CWA. WEDNESDAY...MAINTAINED A DRY FORECAST FOR WEDNESDAY AS GUIDANCE IS PERSISTENT IN INDICATING SHORTWAVE RIDGING ALOFT. MAY HAVE TO INCLUDE POPS FOR WEDNESDAY DEPENDING ON CONVECTIVE EVOLUTION/INFLUENCES ACROSS THE REGION ON TUESDAY...HOWEVER WILL CONTINUE TO FAVOR RIDGING ALOFT AND A DRY FORECAST AT THIS TIME. THURSDAY THROUGH FRIDAY NIGHT...A STRONGER SHORTWAVE TROUGH/CLOSED LOW THAT WAS IN PLACE OVER THE SOUTHWESTERN CONUS THIS AFTERNOON IS FINALLY EXPECTED TO EJECT NORTHEAST OVER THE REGION DURING THIS PERIOD. THE BEST FORCING FOR ASCENT ASSOCIATED WITH THIS TROUGH ARRIVES ON FRIDAY...HOWEVER COULD SEE SOME WARM AIR ADVECTION SHOWERS AND THUNDERSTORMS AS EARLY AS THURSDAY NIGHT AS THE SYSTEM MOVE OVER THE REGION. MOST GUIDANCE INDICATES THAT THIS UPPER LEVEL SYSTEM WILL MOVE DIRECTLY OVER THE CWA. IF THIS PANS OUT WIDESPREAD PRECIPITATION WOULD BE LIKELY...HOWEVER SEVERE WEATHER CHANCES WILL LIKELY BE LIMITED BY A LACK OF DEEP MOISTURE RETURNING TO THE REGION OUT AHEAD OF THE TROUGH. OVERALL EXPECT WIDESPREAD RAIN SHOWER ACTIVITY WITH EMBEDDED THUNDERSTORMS. IF THIS UPPER LEVEL FEATURE REMAINS ON TRACK WILL LIKELY SEE A BUMP IN POPS FOR THE THURSDAY NIGHT INTO FRIDAY TIME FRAME. EXTENDED...THIS SYSTEM IS EXPECTED TO EXIT THE REGION FRIDAY NIGHT BRINGING AN END TO PRECIPITATION CHANCES. MAINTAINED A DRY FORECAST FOR NEXT WEEKEND WITH NO OBVIOUS/SIGNIFICANT FORCING IN THE REGION AT THIS TIME. CAVANAUGH && .AVIATION... /18Z TAFS/ VFR CONDITIONS PREVAILING ACROSS MOST OF NORTH TEXAS THIS AFTERNOON. MAIN CONCERNS WILL BE POTENTIAL CONVECTIVE DEVELOPMENT LATE THIS AFTERNOON AND EVENING. AN MCS WHICH MOVED ACROSS SOUTH TEXAS EARLIER THIS MORNING HAS HELPED SCOUR OUT DEEPER MOISTURE FARTHER NORTH. THIS MAY REDUCE OVERALL CHANCES FOR THUNDERSTORMS THROUGH THE AFTERNOON. CURRENT THINKING IS THAT MOISTURE WILL RECOVER SUFFICIENTLY BY EARLY EVENING FOR THUNDERSTORMS TO DEVELOP ALONG THE COLD FRONT/DRYLINE NEAR WICHITA FALLS. THUNDERSTORMS THAT DO DEVELOP WILL MOVE SOUTHEAST AND MAY IMPACT METROPLEX TAF SITES. FOR NOW...WILL CARRY A VCTS FROM 1-5Z IN THE METROPLEX. THUNDERSTORMS SHOULD MOVE EAST BY MIDNIGHT. WINDS BEHIND ANY COMPLEX OF STORMS WOULD LIKELY BE ERRATIC AND PRIMARILY FROM THE NORTH OR NORTHWEST. FOR NOW...GIVEN UNCERTAINTIES IN LIKELIHOOD OF DEVELOPMENT...WILL LEAVE SOUTHERLY FLOW THROUGH TONIGHT. IF STORMS DEVELOP...THEN AMENDS TO WX AND WIND WILL BE REQUIRED. OTHERWISE...COLD FRONT MOVES THROUGH DURING THE DAY MONDAY WITH WINDS BECOMING NORTHERLY. PRECIP CHANCES WILL LINGER INTO MONDAY HOWEVER BEST CHANCES APPEAR TO BE FARTHER SOUTH AND WEST. DUNN && .PREV UPDATE... .UPDATE... ...MESOSCALE DISCUSSION... REGARDING THUNDERSTORM CHANCES ACROSS NORTH TEXAS THIS AFTERNOON AND EVENING... A DECAYING MESOSCALE CONVECTIVE SYSTEM (MCS) NEAR COLLEGE STATION AT THE TIME OF THIS DISCUSSION HAS HAD A DRAMATIC IMPACT ON THE THERMODYNAMIC ENVIRONMENT ACROSS NORTH TEXAS THIS MORNING. STRONG SUBSIDENCE TO THE NORTH AND WEST OF THIS SYSTEM RESULTED IN A LOWERING OF THE EML CAP OVERNIGHT. THE STRENGTH OF THE CAP ASIDE...THE PRIMARY IMPACT THIS HAS HAD ON OUR THERMODYNAMIC ENVIRONMENT IS TO GREATLY LIMIT THE DEPTH OF MOISTURE IN PLACE IN THE LOW LEVEL ATMOSPHERE OVER MUCH OF NORTH TEXAS. WHILE THE 12Z FWD SOUNDING OBSERVED A 70 NEAR SURFACE DEW POINT THIS MORNING...IT ALSO INDICATED THAT THE DEPTH OF THE MOIST LAYER HAD DECREASED FROM ABOUT 150 MB UP FROM THE SURFACE TO A LITTLE OVER 50 MB ABOVE THE SURFACE. AS A RESULT CONVECTIVE THERMALS INITIATED BY DAYTIME HEATING HAVE BEEN ABLE TO EASILY ENTRAIN DRIER AIR FROM THE EML CAP DOWN TO THE BOUNDARY LAYER WHICH HAS LOWERED SURFACE DEW POINTS INTO THE MID TO UPPER 50S FOR MOST LOCATIONS ALONG AND WEST OF THE INTERSTATE 35 CORRIDOR. WITHOUT ANY MOISTURE ADVECTING BACK INTO THE REGION...THIS DEVELOPMENT SEEMS TO INDICATE THAT SURFACE BASED CONVECTION WILL NOT HAPPEN THIS AFTERNOON ACROSS MUCH OF THE CWA. THE FORECAST IS NOT THAT SIMPLE HOWEVER AS PERSISTENT SOUTHEASTERLY FLOW SOUTH OF THE DECAYING MCS HAS RESULTED IN THE TRANSPORT OF RELATIVELY DEEP GULF MOISTURE UP INTO THE HILL COUNTRY AND ACROSS WEST CENTRAL TX AS OF 17Z. UNCHARACTERISTICALLY DEW POINT VALUES HAVE ACTUALLY IMPROVED WITH THE ONSET OF SOUTH- SOUTHWEST FLOW AT ABILENE AND SWEETWATER LATE THIS MORNING. SPC MESOSCALE ANALYSIS INDICATES THAT A PLUME OF H850 DEW POINTS ABOVE 10 DEG C EXISTS FROM DEL RIO NORTH TO OZONA AND JUST SOUTH OF ABILENE AND SWEETWATER. MOST GUIDANCE INDICATES THAT H850 WINDS WILL REMAIN OUT OF THE SOUTHWEST OUT AHEAD OF A COLD FRONT THAT CONTINUED TO MOVE SOUTHEAST TOWARDS NORTH CENTRAL TX LATE THIS MORNING. CURRENT THINKING IS THAT THIS WILL RESULT IN THE RETURN OF SOME DEEPER GULF MOISTURE INTO THE NORTHWESTERN PORTIONS OF THE CWA BY 00Z OUT AHEAD OF THE ARRIVAL OF THE COLD FRONT. ASSUMING MOISTURE RETURNS...EXPECT THAT FORCING ALONG THE COLD FRONT WOULD RESULT IN THE DEVELOPMENT OF A LINE OF THUNDERSTORMS NEAR A WICHITA FALLS TO OLNEY LINE AROUND 00Z. WITH DEEPER MOISTURE IN PLACE THIS LINE OF STORMS WOULD LIKELY GROW UPSCALE INTO A LINEAR MCS AND THEN MOVE EAST-SOUTHEAST TOWARDS HIGHER THETA-E AIR THAT HAS NOT BEEN ADVERSELY AFFECTED BY SUBSIDENCE ASSOCIATED WITH THE COLLEGE STATION MCS. IF IT DEVELOPS...EXPECTATIONS ARE THAT THIS MCS WILL TRACK TOWARDS THE METROPLEX AROUND 02Z AND CONTINUE EAST OUT OF THE METROPLEX AROUND 04Z. CONFIDENCE IN EXACT TIMING IS SOMEWHAT LOW GIVEN THAT THIS MCS MAY NOT EVEN TAKE SHAPE IF MOISTURE DOES NOT MAKE IT BACK OUT AHEAD OF THE COLD FRONT IN TIME. REGARDLESS...THERE IS SUPPORT IN HIGH RESOLUTION GUIDANCE MEMBERS FOR THIS SOLUTION. THE PRIMARY HAZARDS ASSOCIATED WITH THE MCS WOULD BE DAMAGING STRAIGHT LINE WINDS AND MARGINALLY SEVERE HAIL. A WIDE SWATH OF STRAIGHT LINE WIND DAMAGE IS THE PRIMARY CONCERN...ESPECIALLY IF THIS SYSTEM IS ABLE TO AFFECT THE METROPLEX. STRAIGHT LINE WINDS HAVE A HISTORY OF PRODUCING VERY DANGEROUS CONDITIONS AT OUTDOOR FESTIVALS...ESPECIALLY WHEN PATRONS COLLECT UNDER TENTS TO TAKE COVER FROM THE RAIN. KEPT POPS AT 40 PERCENT FOR NOW DUE TO CONCERNS ABOUT MOISTURE MAKING IT INTO PLACE...BUT WILL UPDATE THE FORECAST THROUGHOUT THE AFTERNOON IF IT LOOKS LIKE THIS SYSTEM IS MORE OR LESS LIKELY TO DEVELOP. IF YOU ARE PLANNING ON ATTENDING OUTDOOR ACTIVITIES OR FESTIVALS THIS EVENING...PLAN ON HAVING SOME ACCESS TO FORECAST UPDATES AND WARNINGS AS SEVERE WEATHER REMAINS POSSIBLE FROM LATE THIS AFTERNOON THROUGH THE EVENING HOURS. CAVANAUGH && .PREV DISCUSSION... /ISSUED 438 AM CDT SUN MAY 6 2012/ DIFFICULT FORECAST DUE TO THE ONGOING CONVECTION OVER THE HILL COUNTRY WHICH...ACCORDING TO ALL MODEL GUIDANCE...SHOULD NOT BE THERE. THESE CONVECTIVE SYSTEMS USE UP AVAILABLE ENERGY FOR CONVECTION...AND WHEN WEAK TROPOSPHERIC WINDS ARE PRESENT...IT LIMITS THE ABILITY FOR THE ATMOSPHERE TO RECHARGE QUICKLY FOR MORE STORMS LATER IN THE DAY. SO THE MODELS END UP BELIEVING WE ARE PRIMED FOR A ROUND OF CONVECTION...WHEN IN REALITY MOST OF THE FUEL HAS ALREADY BEEN SPENT. SO THE FORECAST CHALLENGE IS DETERMINING HOW THIS CURRENT CONVECTION IS GOING TO AFFECT OUR STORM CHANCES LATER TODAY. ALSO COMPLICATING THE FORECAST ARE TWO MCV CIRCULATIONS THAT HAVE DEVELOPED...ONE NEAR LAMPASAS AND ANOTHER NEAR AUSTIN. THE LAMPASAS MCV WILL LIKELY HOLD TOGETHER FOR SEVERAL MORE HOURS DUE TO WEAK WINDS ALOFT...AND MAY BE A FOCUS FOR ELEVATED CONVECTION THIS MORNING. WILL INCLUDE POPS IN THE SW ZONES THIS MORNING FOR THIS FEATURE. MEANWHILE A COLD FRONT IS BARRELING DOWN THE FRONT RANGE OF THE ROCKIES AND SHOULD BE THROUGH THE TX PANHANDLE BY NOON. THIS FRONT WILL SLOW DOWN THIS AFTERNOON...BUT WINDS OVER OUR REGION WILL LIKELY VEER A BIT TO THE SOUTHWEST. THIS SETUP NORMALLY RESULTS IN TEMPS WELL ABOVE GUIDANCE...HOWEVER THERE IS THICK MID-HIGH CLOUD COVER THAT IS STREAMING OVER THE AREA FROM THE CENTRAL TEXAS CONVECTION. ALTHOUGH CLOUDS SHOULD THIN OUT DURING THE DAY IT WILL STEAL A FEW HOURS OF INSOLATION. HIGHS TODAY ARE VERY SENSITIVE TO HOW MUCH SUNSHINE WE GET AND COULD BE EITHER TOO WARM OR COOL. THE CENTRAL TEXAS CONVECTION IS USING UP A LOT OF THE RICH MOISTURE AND INSTABILITY...AND LATEST SURFACE OBS SHOW A SWATH OF 40S AND 50S DEWPOINTS FROM GRAHAM SOUTHWARD TO BURNET DOWNSTREAM FROM THE SYSTEM. THE DRY AIR IS BROUGHT TO THE SURFACE DUE TO INTENSE SUBSIDENCE ON THE BACKSIDE OF THE SYSTEM...AND WE HAVE EVEN NOTED A FEW HEATBURST EVENTS EARLIER. HOWEVER...THE HIGH MOISTURE/INSTABILITY REMAINS UNDISTURBED EAST OF A LINE FROM CAMERON TO MINERAL WELLS TO WICHITA FALLS WHERE DEWPOINTS REMAIN NEAR 70. THIS REGION WILL LIKELY BE THE MOST UNSTABLE AREA...AND SHOULD BE PRIMED FOR CONVECTION THIS EVENING. IT REMAINS TO BE SEEN IF THE AIR MASS IN THE WESTERN ZONES CAN RECOVER...AND THUS THE DRY LINE MAY HAVE TROUBLE INITIATING STORMS IN WESTERN ZONES. WATER VAPOR LOOP SHOWS A SHORTWAVE MOVING NORTHEAST INTO THE BIG BEND REGION NOW AND MODEL GUIDANCE BRINGS THIS ACROSS THE NW ZONES BY SUNSET. EXPECT THIS LIFT TO HELP INITIATE STORMS ALONG THE FRONT OR DRY LINE...MAINLY ACROSS THE NW ZONES BY EARLY EVENING. INSTABILITY WILL BE GREATEST IN AN AXIS ALONG I-35 WHERE MLCAPE REACHES 3500J/KG. ALTHOUGH DEEP LAYER SHEAR IS TOO WEAK FOR SUSTAINED SUPERCELLS...THERMODYMIC/KINEMATIC CONDITIONS LOOK VERY FAVORABLE FOR INTENSE COLD POOL FORMATION. ONCE CONVECTION FORMS IT WILL PROPAGATE S/SE INTO THE INSTABILITY AXIS AND DIRECTION OF THE LOW LEVEL FLOW. STORMS MAY START OUT NEAR BOWIE...GROW UPSCALE AS THEY SPREAD SOUTHEAST THROUGH THE METROPLEX AND INTO THE SOUTHEAST ZONES BEFORE DISSIPATING. THIS SCENARIO IS BEING MODELED BY THE HI-RES WRF MODELS...AND GIVEN THE LARGE SWATH OF QPF FROM THE ECMWF/GFS...INCREASED POPS TO 30-40 FOR THE CENTRAL/EASTERN ZONES. SEVERE THREAT LOOKS HIGHEST ACROSS THE NORTH CENTRAL ZONES INCLUDING THE METROPLEX. DAMAGING WIND IS THE PRIMARY THREAT...BUT HAIL WILL ALSO BE POSSIBLE. COLD FRONT WILL QUIETLY MOVE THROUGH ON MONDAY AND EXPECT STORMS TO REDEVELOP BY MONDAY AFTERNOON NEAR THE BOUNDARY AS IT LIES ACROSS THE SOUTHERN ZONES. INSTABILITY IS MUCH MORE LIMITED MONDAY AFTERNOON SO SEVERE THREAT IS LOW. HIGH TEMPS WILL BE COOLEST IN THE NORTHERN ZONES AND ONLY NEAR 80...BUT STILL EXPECT HIGHS NEAR 90 IN THE SOUTH. A SHORTWAVE WILL MOVE INTO WEST TEXAS MONDAY NIGHT WITH WIDESPREAD CONVECTION DEVELOPING TO OUR WEST. THIS SHORTWAVE AND REMNANT CONVECTION WILL MOVE INTO OUR REGION BY TUESDAY MORNING WITH THE CHANCES OF RAIN INCREASING AREA WIDE. INSTABILITY IS VERY LIMITED AND WINDS ARE VERY LIGHT ALOFT...AND EVENT MAY END UP BEING JUST SCATTERED ELEVATED RAIN SHOWERS. HIGHS TUESDAY WILL BE IN THE 70S COMPLEMENTS OF THE CLOUDS/RAIN. SHORTWAVE TROUGH MOVES THROUGH BY WEDNESDAY MORNING AND DRY/COOL ADVECTION CONTINUES BEHIND THE FRONT. EVEN WITH SOME SUN HIGHS WILL STILL BE COOL AND ONLY NEAR 80. LOWS SHOULD BENEFIT FROM RADIATIONAL COOLING AND DROP INTO THE 50S THURSDAY. CUT OFF UPPER LEVEL LOW THAT WILL HANG OUT IN ARIZONA MONDAY THROUGH WEDNESDAY WILL FINALLY MOVE ACROSS TEXAS FRIDAY...AND THIS WILL BRING THE CHANCE OF RAIN BACK ON FRIDAY. MOISTURE/INSTABILITY LOOK TOO LIMITED FOR SEVERE WEATHER. THE COOL TEMPS CONTINUE INTO NEXT WEEKEND AS THE CONTINENTAL AIR MASS IS REINFORCED. TR.92 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
