NATIONAL WEATHER SERVICE FORT WORTH TX
1251 AM CDT WED MAY 30 2012

.UPDATE...
QUICK UPDATE TO INCLUDE SEVERE THUNDERSTORM WATCH 320. WILL ALSO
BUMP POPS UP IN THE NORTH/NORTHEAST TO ACCOUNT FOR STORMS MOVING
SOUTH/SOUTHEAST FROM SOUTHERN OKLAHOMA.

79

&&

.AVIATION...
/06Z TAFS/

CONCERNS...CONVECTION LATE NIGHT/EARLY MORNING.

GUSTY WINDS TONIGHT...
STRONG WINDS FROM DISSIPATING STORMS WILL CONTINUE SUBSIDING...
WILL LIKELY NOT NEED TO BE INCLUDED IN INITIAL GROUPS OF 06Z TAFS.

CONVECTION LATE TONIGHT/EARLY MORNING...
ALTHOUGH EVENING CONVECTION NEAR TAF SITES HAS DISSIPATED...
ACTIVITY IN OKLAHOMA IS ORGANIZING INTO AN MCS. TIME OF ARRIVAL
STILL IN REMARKABLY GOOD SHAPE...10Z (5 AM CDT) OR THEREAFTER.
WIDESPREAD DOWNBURST HAS REDUCED THE BUOYANCY OF THE SURFACE
LAYER...BUT MCS MAY BE UNABLE TO INGEST SURFACE PARCELS ANYWAY.
EXPECT INTENSITY TO WANE AS THE MCS CROSSES THE RED RIVER...BUT
SOME EMBEDDED THUNDER SHOULD PERSIST.

WEDNESDAY...
STRONG SOUTHERLY WINDS WILL LIKELY EXCEED 15KTS MUCH OF THE DAY.

WACO...
DO NOT ANTICIPATE THAT THE MCS WILL BE ABLE TO PROPAGATE INTO
CENTRAL TEXAS BEFORE DISSIPATING AFTER DAYBREAK. STRONGER WINDS ON
WEDNESDAY. STRATUS INTRUSION WEDNESDAY NIGHT MAY BE AS EARLY AS
06Z...BUT WILL NOT INCLUDE AT THIS TIME.

EXTENDED...
AN MVFR STRATUS INTRUSION IS LIKELY LATE WEDNESDAY NIGHT INTO
THURSDAY MORNING. HAVE INTRODUCED INTO EXTENDED PORTION OF TAFDFW.

.PREV UPDATE...
.UPDATE...

ISSUED A HIGH WIND WARNING FOR THE DFW METROPLEX AND SURROUNDING
AREAS DUE TO HIGH WINDS BEING REPORTED ACROSS THE AREA AS LIGHT
PRECIPITATION FROM ORPHANED ANVIL CLOUDS DRAGS STRONG WINDS ALOFT
DOWN TO THE SURFACE. DALLAS LOVE FIELD RECORDED A 58 MPH WIND GUST
EARLIER AND REPORTS OF LIGHT WIND DAMAGE HAVE BEEN REPORTED FROM
PARKER COUNTY EAST THROUGH DALLAS COUNTY. DO NOT EXPECT THE WINDS
TO PERSIST FOR MORE THAN A COUPLE HOURS AS THEIR STRENGTH SEEMS
HIGHLY DEPENDENT ON THE MAINTENANCE OF THE ANVIL LEVEL
PRECIPITATION WHICH IS NO LONGER BEING FED HYDROMETEORS FROM A
PARENT THUNDERSTORM.

THE NEXT AREA OF CONCERN IS THE DOWNWIND PROPAGATING MCS THAT HAS
ORGANIZED ACROSS SOUTHERN OKLAHOMA. WILL CONTINUE TO MONITOR THIS
ACTIVITY FOR DAMAGING WIND POTENTIAL AS IT CROSSES THE RED RIVER
AFTER MIDNIGHT. THE LOSS OF DAYTIME HEATING AND THE ENHANCEMENT OF
THE ANVIL PRECIPITATION IN TRANSPORTING HIGH MOMENTUM AIR ALOFT TO
THE SURFACE INDICATES THAT A STABLE LAYER DOMINATES THE LOWER
TROPOSPHERE OVER NORTH TEXAS. ASSUMING THIS IS VALID...WOULD
ANTICIPATE THAT THIS LARGELY SURFACE BASED MCS WILL STRUGGLE TO
SUSTAIN ITSELF ONCE IT CROSSES THE RED RIVER. IT IS BECOMING A
FAIRLY WELL ORGANIZED SYSTEM...BUT APPEARS TO LACK STRONG
MESOSCALE PRESSURE FEATURES THAT WOULD TEND TO DYNAMICALLY SUSTAIN
THIS SYSTEM IN SPITE OF THE SOMEWHAT INHIBITIVE DOWNSTREAM SURFACE
BASED THERMODYNAMIC ENVIRONMENT. DO NOT THINK THAT THEY WILL
TOTALLY DISSIPATE SOUTH OF THE RED RIVER...BUT THINK THAT THEY
WILL STRUGGLE TO CONTAIN THEIR OUTFLOW AS THE CROSS THE RED RIVER
MAKING SEVERE WEATHER IMPACTS SOMEWHAT LESS LIKELY. WILL CONTINUE
TO MONITOR RADAR TRENDS AND THE THERMODYNAMIC ENVIRONMENT AND
ISSUE WARNINGS FOR WIND AND HAIL AS NECESSARY.

CAVANAUGH

.PREV DISCUSSION... /ISSUED 305 PM CDT TUE MAY 29 2012/
A FRONT EXTENDS FROM THE GREAT LAKES SOUTHWESTWARD ACROSS OKLAHOMA
TO A SURFACE LOW OVER THE TEXAS PANHANDLE. THE DRYLINE EXTENDS
FROM THE LOW PRESSURE CENTER SOUTHWARD ACROSS WEST-CENTRAL TEXAS.
THE DRYLINE HAS BEGUN TO PUSH EAST THIS AFTERNOON...AND WILL LIKELY
BECOME THE FOCUS FOR ISOLATED STORMS DURING THE LATE AFTERNOON
HOURS JUST WEST OF NORTH TEXAS COUNTIES. THE UPPER LEVEL PATTERN
IS NOT QUITE AS CONDUCIVE FOR DEVELOPMENT AS YESTERDAY DUE IN
PART TO INCREASED HEIGHTS ACROSS THE AREA EXTENDING FROM THE
STRONG UPPER RIDGE OVER MEXICO. NONETHELESS...THE ATMOSPHERE HAS
RECOVERED QUICKLY OVER THE PAST 12 TO 18 HOURS. SB CAPE HAS
ALREADY CLIMBED ABOVE 2500 J/KG PER THE LATEST ANALYSES AND SHOULD
TOP OUT OVER 3000 OVER THE WESTERN COUNTIES AHEAD OF THE SURFACE
BOUNDARY. THIS COUPLED WITH PLENTY OF MOISTURE AND FAIRLY STEEP
MID LEVEL LAPSE RATES SHOULD LEAD TO THE DEVELOPMENT OF A FEW
STRONG TO SEVERE STORMS DURING THE LATE AFTERNOON HOURS...WITH THE
BEST CHANCE OVER THE NORTHWESTERN COUNTIES.

THE HIGHEST THUNDERSTORM COVERAGE WILL LIKELY OCCUR ALONG THE COLD
FRONT ACROSS OKLAHOMA THIS EVENING AS A SHORTWAVE DROPS SOUTHEAST
INTO THE CENTRAL PLAINS. HIGH RESOLUTION MODELS SHOW THE POSSIBILITY
OF THESE STORMS BECOMING ORGANIZED AS THEY PROPAGATE SOUTHEAST
TOWARDS THE RED RIVER TONIGHT. THE BEST STORM CHANCES WOULD OCCUR
LATE TONIGHT IF A MCS DEVELOPS TO OUR NORTH...THEN HOLDS TOGETHER
AS IT MOVES SOUTH OF THE RED RIVER. WILL KEEP THE HIGHEST RAIN
CHANCES OVER THE NORTHEASTERN COUNTIES ALONG THE LIKELY PATH OF
PROPAGATION. SOME OF THE STORMS MAY PRODUCE DAMAGING WINDS BEFORE
THE POTENTIAL COMPLEX WEAKENS TOMORROW MORNING.

A STRONGER SHORTWAVE WILL SWEEP SOUTHEASTWARD FROM MONTANA INTO
THE NORTHERN AND CENTRAL PLAINS TOMORROW NIGHT INTO THURSDAY. THIS
SHOULD GIVE THE FRONT THE PUSH IT NEEDS TO MOVE SOUTHEAST ACROSS
THE FORECAST AREA ON THURSDAY. SHOWERS AND STORMS WILL AGAIN
DEVELOP ALONG THE BOUNDARY LATE TOMORROW AND SPREAD SOUTHEAST
ACROSS NORTH TEXAS TOMORROW NIGHT AND THURSDAY. RAIN CHANCES WILL
FINALLY COME TO AN END THURSDAY NIGHT AS THE FRONT PUSHES SOUTH OF
THE REGION. THIS SHOULD BRING AN END TO THE SUMMER-LIKE
TEMPERATURES FOR AT LEAST A SHORT WHILE....WITH LOWS IN THE 50S
AND 60S AND HIGHS IN THE LOW TO MID 80S EXPECTED BY THE END OF THE
WEEK.
