AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
114 PM CDT MON APR 11 2016

.AVIATION...
/18Z TAFS/

CONCERNS...POTENTIAL FOR THUNDER AT THE METROPLEX AIRPORTS THIS
AFTERNOON. COLD FRONT MOVES THROUGH THIS AFTERNOON AND EVENING
WITH A RETURN OF MVFR CIGS BEHIND THE FRONT.

SCT-BKN CIGS WITH BASES BETWEEN 025-050 KFT CONTINUE ACROSS THE
TAF SITES AT THE START OF THE VALID TAF PERIOD. A COLD FRONT IS
CURRENTLY LOCATED NEAR THE RED RIVER AND A DRYLINE IS MOVING EAST
TOWARDS THE I-35 CORRIDOR. THUNDERSTORMS ARE EXPECTED TO INITIATE
ON THE DRYLINE WEST OF DFW AROUND 20-21Z. FOR THE WACO AREA...THE
THREAT FOR THUNDERSTORMS IS LOWER AND WILL NOT MENTION VCTS IN THE
KACT TAF AT THIS TIME...BUT WILL BE CLOSELY MONITORING CONVECTIVE
DEVELOPMENT FOR POSSIBLE AMENDMENTS TO THE KACT TAF. FOR THE
METROPLEX...WILL CARRY VCTS FROM 21-00Z. ANY THUNDERSTORM THAT
AFFECTS THE AIRPORTS THIS AFTERNOON MAY BE SEVERE WITH A THREAT
FOR LARGE HAIL AND POSSIBLY STRONG WINDS.

THE COLD FRONT WILL MOVE ACROSS THE METROPLEX LATE THIS AFTERNOON.
THE WINDS WILL SHIFT TO THE NORTH AROUND 21-22Z BEFORE THE TRUE
FRONT ARRIVES. BETWEEN 21-00Z...ITS POSSIBLE THE WINDS WILL BE
VARIABLE BUT THEN EVENTUALLY BECOME NORTHERLY CLOSER TO 00Z. THE
FRONT IS EXPECTED TO ARRIVE AT KACT ABOUT 01Z. MVFR CIGS WILL
BUILD BEHIND THE FRONT WITH BASES BETWEEN 1-2 KFT. HOWEVER...CIGS
AT KACT ARE EXPECTED TO LOWER BELOW 1 KFT OVERNIGHT. IFR/MVFR CIGS
WILL HOLD THROUGH MOST OF THE MORNING AND THERE SHOULD BE SOME
IMPROVEMENT AROUND MIDDAY TUESDAY.

.UPDATE...
MAIN CONCERN IN THE SHORT TERM CONTINUES TO BE THE SEVERE
THUNDERSTORM POTENTIAL FOR THIS AFTERNOON AND EVENING OVER
PORTIONS OF NORTH CENTRAL TEXAS. WHILE THUNDERSTORM COVERAGE IS
NOT EXPECTED TO BE WIDESPREAD TODAY THUNDERSTORMS THAT DO DEVELOP
WILL HAVE THE POTENTIAL TO BE SEVERE. WE HAVE SLIGHTLY MODIFIED
THE SEVERE WEATHER POTENTIAL AREA TO BE A BIT FURTHER WEST AND
SOUTH AS A SURFACE LOW IS PROGGED TO TRACK ACROSS NORTH TEXAS
AND COMBINE WITH AN APPROACHING DRY LINE AND ALSO A COLD FRONT AND
SOME REMNANT OUTFLOW FROM THIS MORNINGS STORMS ALONG THE RED
RIVER. OUR MAIN AREA OF CONCERN IS FOR ISOLATED TO SCATTERED
SEVERE STORMS PRIMARILY NORTH OF I-20. A SECONDARY BUT MORE
ISOLATED POTENTIAL EXISTS SOUTH OF I-20 AND ALONG AND EAST OF I-35.
THIS DOES INCLUDE THE POSSIBILITY FOR SEVERE STORMS OVER THE
METROPLEX WITH A SMALLER POSSIBILITY THE FURTHER SOUTH YOU GO
TOWARDS WACO.

.PREV DISCUSSION... /ISSUED 404 AM CDT MON APR 11 2016/
MORNING WATER VAPOR IMAGERY SHOWS A SHORTWAVE TROUGH OVER SOUTHERN
NEW MEXICO SLOWLY SPREADING EAST INTO WEST TEXAS. AHEAD OF THIS
FEATURE IS A STEADY STREAM OF MID AND HIGH LEVEL MOISTURE THAT
EXTENDS EASTWARD THROUGH TEXAS AND INTO THE MID MISSISSIPPI RIVER
VALLEY. AT THE SURFACE...A COLD FRONT IS DRAPED ACROSS NORTHERN
OKLAHOMA WITH A DRYLINE ACROSS WEST TEXAS...JUST WEST OF MIDLAND.
STRONG SOUTHERLY FLOW PREVAILS ACROSS MUCH OF CENTRAL AND NORTH
TEXAS AND IS CONTINUING TO ADVECT IN RICH LOW LEVEL MOISTURE
RESULTING IN EXTENSIVE LOW CLOUD COVER. THE WIND/PRESSURE FIELDS
ACROSS SOUTHERN OKLAHOMA HAVE BEEN PERTURBED BY AN EASTWARD MOVING
COMPLEX OF THUNDERSTORMS BUT SHOULD BEGIN TO RECOVER THROUGH THE
MID MORNING HOURS. A FEW SCATTERED THUNDERSTORMS HAVE MOVED OUT OF
WEST CENTRAL TEXAS INTO OUR AREA AND PERSIST BETWEEN BRECKENRIDGE
SOUTHEAST TOWARD HAMILTON. THESE ARE ASSOCIATED WITH AMPLE MID
LEVEL MOISTURE...ELEVATED ABOVE A STRONG CAPPING INVERSION AND
SHOULD POSE MINIMAL SEVERE WEATHER RISK OVER THE NEXT FEW HOURS.
LIGHTNING AND POSSIBLY SOME SMALL HAIL WILL BE THE MAIN THREATS
BASED ON AVAILABLE INSTABILITY FROM RAP SOUNDINGS. THIS ACTIVITY
IS LIKELY TO CONTINUE TO MOVE NORTHEAST THROUGH THE EARLY MORNING
HOURS.

THE MAIN CONCERN THROUGH THIS EVENING IS THE POTENTIAL FOR SEVERE
THUNDERSTORMS ACROSS PARTS OF NORTH TEXAS AS THE MAIN SHORTWAVE
LIFTS NORTHEAST ACROSS THE SOUTHERN PLAINS. SCATTERED
THUNDERSTORMS ARE EXPECTED ALONG THE COLD FRONT ACROSS MUCH OF
OKLAHOMA AS IT SLIDES SOUTHWARD THROUGH THE DAY. AHEAD OF THE
FRONT...THE WEST TEXAS DRYLINE WILL MOVE EAST AND SHOULD BE
POSITIONED SOMEWHERE NEAR THE I-35 CORRIDOR BY EARLY AFTERNOON.
EAST OF THE DRYLINE...A VERY MOIST AND UNSTABLE ENVIRONMENT WILL
RESIDE...ALTHOUGH IT WILL BE STRONGLY CAPPED. A SURFACE LOW IS
EXPECTED TO CLOSE OFF AND MOVE NORTHEAST THROUGH THE DAY AND WILL
LIKELY BE POSITIONED NEAR THE RED RIVER LATE THIS AFTERNOON
SOMEWHERE IN THE VICINITY OF OUR NORTHEAST COUNTIES...PLACING THE
TRIPLE POINT IN THE PARIS AREA. IT IS STILL A LITTLE UNCERTAIN AS
TO HOW MANY STORMS WILL BE CAPABLE OF DEVELOPING IN THE VERY
UNSTABLE AIR EAST OF THE DRYLINE AS THE BEST LIFT WILL TRACK
ACROSS CENTRAL OKLAHOMA AND INTO THE OZARKS BY THIS EVENING. IN
ADDITION...EARLY MORNING CONVECTION MAY LOCALLY PERTURB THE WARM
MOIST SECTOR...ALTHOUGH THIS MAY BE MORE OF AN ISSUE IN OKLAHOMA.
THE BIGGER ISSUE IS EXPECTED TO BE THE STRONG CAPPING INVERSION.
FORECAST SOUNDINGS SUGGEST THAT INHIBITION WILL WEAKEN THIS
AFTERNOON AS THE DRYLINE APPROACHES AND FORCING FROM THE TROUGH
INCREASES BUT IT REMAINS IN QUESTION AS TO WHETHER OR NOT IT WILL
BE SUFFICIENT FOR DEEP CONVECTION TO DEVELOP.

THE CURRENT THINKING IS THAT OUR FAR EASTERN AREAS WILL HAVE THE
BEST CHANCE FOR THUNDERSTORMS LATE THIS AFTERNOON AND EVENING.
AREAS FROM BONHAM TO PARIS TO SULPHUR SPRINGS AND THEN SOUTH
TOWARD THE PALESTINE AREAS ARE MOST LIKELY TO HAVE A SUFFICIENTLY
WEAKENED CAP FOR THUNDERSTORMS. THERE WILL ALSO BE A SMALL
SECONDARY FAVORED AREA ALONG THE RED RIVER BACK TO THE WEST TOWARD
GAINESVILLE AND BOWIE AS THE COLD FRONT SURGES SOUTH. THIS WOULD
OCCUR BEFORE ALL OF THE LOW LEVEL MOISTURE GETS SCOURED OUT. SO
WILL HAVE THE HIGHEST POPS ALONG THE RED RIVER AND INTO OUR
NORTHEAST AND EASTERN COUNTIES THROUGH THIS EVENING.

WIND PROFILES AND INSTABILITY WILL SUPPORT SUPERCELLS THIS
AFTERNOON AND EVENING...ESPECIALLY ACROSS THE FAR EAST AND
NORTHEAST COUNTIES. THERE IS A TORNADO THREAT...ALTHOUGH IT
APPEARS TO BE GREATEST NEAR THE TRIPLE POINT WHERE LOW LEVEL WINDS
ARE LOCALLY BACKED. THE BIGGER THREAT TODAY WILL LIKELY BE LARGE
HAIL AS MID LEVEL LAPSE RATES ARE VERY STEEP AND INSTABILITY
EXCEEDS 3000 J/KG IN OUR FAR EASTERN AREAS.

CONCERNS FOR CONVECTION FARTHER WEST INTO MORE DENSELY POPULATED
AREAS DO EXIST TO SOME EXTENT AS THE LATEST RUNS OF THE 4KM NAM
HOLD THE DRYLINE BACK A LITTLE FARTHER WEST...ALTHOUGH THEY DO NOT
REALLY INITIATE CONVECTION. THIS IS LIKELY DUE TO THE FACT THAT
THE CAPPING INVERSION IS SO STRONG AND WESTERN AREAS WILL BECOME
SUBSIDENT AS THE TROUGH MOVES BY SOONER. AT THIS TIME...THINK THE
BEST CHANCES FOR SEVERE WEATHER WILL REMAIN TO THE EAST OF THE
I-35 CORRIDOR.

ALL OF THIS ACTIVITY WILL MOVE EAST THIS EVENING AS THE TROUGH
QUICKLY MOVES THROUGH THE SOUTHERN PLAINS AND A COLD FRONT MOVES
SOUTH THROUGH THE AREA OVERNIGHT. TUESDAY WILL BE ABOUT 15 DEGREES
COOLER THAN TODAY WITH HIGHS IN THE UPPER 60S AND LOWER 70S.
MOISTURE ABOVE THE COOLER AIR WILL NOT GET SCOURED OUT AND ANOTHER
FAIRLY STRONG SHORTWAVE IS EXPECTED TO APPROACH THE AREA LATE
TUESDAY. SO DESPITE THE FRONT COMING THROUGH...TUESDAY IS SHAPING
UP TO BE MOSTLY CLOUDY WITH ADDITIONAL RAIN CHANCES ON THE WAY.

SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP AND
MOVE THROUGH CENTRAL TEXAS AND PARTS OF NORTH TEXAS TUESDAY NIGHT
INTO WEDNESDAY. IT LOOKS LIKE THE BEST CHANCES FOR SHOWERS AND
THUNDERSTORMS WILL BE ALONG AND SOUTH OF INTERSTATE 20 DURING THIS
TIME...WITH MOST OF THE ACTIVITY ENDING EARLY WEDNESDAY MORNING.

WEDNESDAY NIGHT THROUGH FRIDAY NIGHT LOOKS DRY WITH MODEL GUIDANCE
STILL SHOWING A SYSTEM DEEPENING AND AFFECTING THE AREA OVER NEXT
WEEKEND. THE UPPER PATTERN RESEMBLES AN OMEGA BLOCK OVER THE CONUS
WITH A CLOSED OFF LOW JUST TO THE WEST OF TEXAS. THIS WOULD
SUPPORT SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS AND COULD POSE
OUR FIRST SIGNIFICANT FLOOD THREAT IN A WHILE. STAY TUNED!
