AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
345 AM CDT MON OCT 6 2014

.DISCUSSION...

SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE REGION THIS
MORNING WITH THE MAJORITY OF THE ACTIVITY OCCURRING EAST OF
INTERSTATE 35/35E. AT 3 AM...A SMALL LINEAR COMPLEX OF
THUNDERSTORMS WAS ABOUT TO CROSS THE RED RIVER WHILE OTHER
ISOLATED SHOWERS/STORMS WERE DEVELOPING IN AND WEST OF THE DFW
METROPLEX. AT THIS TIME...THE STORMS NEAR THE RED RIVER WERE THE
STRONGEST BUT BELOW SEVERE LIMITS. STRONG OR MARGINALLY SEVERE
STORMS WILL BE POSSIBLE THROUGH THE MORNING HOURS AS THE STORMS
CONTINUE MOVING SOUTHEAST. HAIL AROUND 1 INCH AND/OR GUSTY WINDS
UP TO 50 MPH WILL BE POSSIBLE WITH THE STRONGEST STORMS. THROUGH
MIDDAY...HAVE THE HIGHEST POPS OVER ROUGHLY THE EASTERN HALF OF
THE CWA.

THE MODELS ARE SUGGESTING A CONDITIONAL SEVERE CONVECTIVE
POTENTIAL WILL EXIST THIS AFTERNOON FOR PART OF THE REGION.
AROUND MIDDAY...SEVERAL OF THE MODELS MOVE A H700 THERMAL RIDGE
ACROSS THE REGION RESULTING IN DECENT WARM AIR ADVECTION FROM WEST
TO EAST. THIS WAA WILL OCCUR UNDER VERY COLD TEMPERATURES IN THE
MID LEVELS OF THE ATMOSPHERE WHERE H500 TEMPS ARE AROUND -12
DEGREES C. THE COLD TEMPERATURES ALOFT COMBINED WITH WARM
TEMPERATURES AT THE SURFACE IN THE UPPER 80S AND LOWER 90S THIS
AFTERNOON RESULTS IN MODERATE TO HIGH CAPE VALUES BETWEEN
2500-3500 J/KG. THE WARM TEMPERATURES AT THE SURFACE ARE ENOUGH TO
OVERCOME THE WAA NEAR H700 WITH LITTLE TO NO CAP ON FORECAST
SOUNDINGS. IN ADDITION...BULK SHEAR VALUES ARE SUPPORTIVE OF
SUPERCELLS WITH VALUES AROUND 40-45 KTS AND MID LEVEL LAPSE RATES
ARE STEEP BETWEEN THE WARMING TEMPS AT H700 AND THE COLD TEMPS AT
H500.

THE QUESTION IS...WILL WE GET STORMS? A SIGNIFICANT DISTURBANCE IS
NOT NOTED IN THE MODELS TO PROVIDE LARGE SCALE LIFT ACROSS THE
REGION. BUT THE MODELS ARE INDICATING LIFT OCCURRING ACROSS THE
REGION WHICH MAY BE TIED TO THE WAA AROUND THE H700 LAYER. SEVERAL
OF THE SYNOPTIC MODELS ARE PRODUCING QPF OVER THE SOUTHERN AND
SOUTHEASTERN COUNTIES THIS AFTERNOON ON THE SOUTHEASTERN FRINGE OF
THE THERMAL RIDGE. HOWEVER...THE LATEST HI-RES MODELS ARE NOT
DEVELOPING ANY STORMS IN THE REGION. ANOTHER INTERESTING FEATURE
TO NOTE IS THAT THE RAP...ECMWF...CANADIAN ALL DEVELOP A DRYLINE
OVER OUR WESTERN COUNTIES THIS AFTERNOON. IF THIS IS REALIZED...IT
COULD BE A FOCUS FOR CONVECTIVE DEVELOPMENT THIS AFTERNOON.
ALSO...WILL HAVE TO MONITOR FOR ANY BOUNDARIES LEFT OVER FROM THIS
MORNING/S CONVECTION.

IN SUMMARY...CONFIDENCE IS LOW THAT STORMS WILL DEVELOP SOME WHERE
IN THE CWA THIS AFTERNOON BUT IF STORMS DO DEVELOP THEY HAVE A
CHANCE TO BECOME SEVERE WITH A DAMAGING WIND AND HAIL THREAT. FOR
NOW...WILL CARRY 20-30 POPS EAST OF A LINE FROM SHERMAN TO FORT
WORTH TO COMANCHE. THROUGHOUT THE DAY...WILL NEED TO MONITOR THE
MESOSCALE FEATURES AND ENVIRONMENT AND ALSO SHORT-TERM AND HI-RES
MODELS FOR POSSIBLY EARLY HINTS THAT CONVECTION WILL DEVELOP THIS
AFTERNOON.

FOR THE OVERNIGHT HOURS TONIGHT...ADDITIONAL STORMS ARE LIKELY TO
OCCUR ACROSS EASTERN OKLAHOMA IN ANOTHER AREA OF WAA. SPC HAS
HIGHLIGHTED AREAS JUST NORTH AND NORTHEAST OF THE CWA FOR STRONG
OR SEVERE STORMS OVERNIGHT...BUT WILL LEAVE A 20 POP ACROSS OUR
NORTHEASTERN COUNTIES.

OUR PERSISTENT CYCLONIC FLOW ALOFT WILL BE REPLACED BY UPPER LEVEL
RIDGING ON TUESDAY. THIS WILL ALLOW TEMPERATURES TO REACH THE 90S
ACROSS MUCH OF THE AREA TUESDAY THROUGH THURSDAY. THE RIDGE WILL BE
PUSHED INTO THE GULF OF MEXICO AS THE REMNANTS OF SIMON MERGE WITH
A WEAK TROUGH NEAR THE WEST COAST. THIS TROUGH MOVES INTO THE
PLAINS THIS WEEKEND ALLOWING FOR A FRONT TO SLIDE INTO THE REGION
ON FRIDAY. LATEST MODEL GUIDANCE SUGGESTS THE FRONT WILL STALL
ACROSS THE REGION AND RETREAT NORTH ON SUNDAY...BUT IT WILL BRING
A CHANCE FOR RAIN ACROSS THE REGION FRIDAY AND SATURDAY. WILL
CARRY LOW RAIN CHANCES INTO THE EARLY PART OF NEXT WEEK AS BROAD
TROUGHING SETS UP OVER MUCH OF THE COUNTRY AND SOUTH WINDS KEEP
ADEQUATE MOISTURE ACROSS THE REGION FOR PRECIPITATION.

.AVIATION...
/ISSUED 1146 PM CDT SUN OCT 5 2014/
A COMPLEX OF STORMS CURRENTLY ORGANIZING ACROSS OKLAHOMA WILL BE
THE PRIMARY AVIATION WEATHER CONCERN OVERNIGHT. MODELS...INCLUDING
HI RES SOLUTIONS...HAVE BEEN HAVING A TOUGH TIME SHOWING ANY RUN
TO RUN CONTINUITY. OUR CURRENT THINKING IS THAT THE OKLAHOMA
CONVECTION WILL REACH THE RED RIVER COUNTIES BETWEEN 06 AND 07Z AS
AN UPPER LEVEL DISTURBANCE APPROACHES FROM THE NORTH. STORMS
SHOULD REMAIN ELEVATED IN NATURE AND MAY WEAKEN SOME AS THEY MOVE
ACROSS NORTH TEXAS SINCE THE BEST UPPER LEVEL FORCING SHOULD STAY
NORTH OF THE RED RIVER. WE WILL MAINTAIN A VCTS AT THE METROPLEX
AIRPORTS FROM 09 TO 12Z AND IN WACO FROM 11 TO 15Z.

ANOTHER AVIATION CONCERN OVERNIGHT/MONDAY MORNING WILL BE MVFR
CEILINGS/VISIBILITY. KFWS VAD SHOWS A 35 KNOT LOW LEVEL JET IN
PLACE AND MVFR CEILINGS HAVE ALREADY DEVELOPED AROUND THE BALCONES
ESCARPMENT. WE EXPECT MVFR CEILINGS TO REACH WACO BETWEEN 08 AND
09Z AND THE METROPLEX TAF SITES SHORTLY AFTER THAT. THE LOW
CEILINGS SHOULD LINGER THROUGH MUCH OF MONDAY MORNING.
HOWEVER...ANY OUTFLOW BOUNDARIES FROM OVERNIGHT CONVECTION MAY
CLEAR THE CEILINGS OUT EARLIER. VFR CONDITIONS ARE EXPECTED MONDAY
AFTERNOON AND EVENING.

A SOUTH WIND WILL PREVAIL THROUGH MONDAY EVENING AT SPEEDS BETWEEN
7 AND 13 KNOTS ALONG WITH A FEW HIGHER GUSTS...ESPECIALLY DURING
THE DAYLIGHT HOURS MONDAY.
