WILL EXPIRE SEVERE WATCH 356 AT MIDNIGHT. ONE SEVERE THUNDERSTORM

THUNDERSTORMS CONTINUE TO MOVE THROUGH METROPLEX TERMINALS TONIGHT
AND SHOULD MOVE EAST OF THE AIRPORTS BY ISSUANCE TIME. WILL LEAVE
A VCTS IN AT DFW/DAL AND CAN MAKE LAST MINUTE ADJUSTMENT BASED ON
LATEST RADAR IF PRECIP APPEARS TO LINGER. OTHERWISE...VFR CONDS
EXPECTED WITH SOUTH FLOW. COULD SEE SOME MVFR CIGS WORK BACK INTO
ACT BY EARLY MORNING SO WILL HAVE BKN020 THERE BY 12Z. SOUTHERLY
FLOW AND VFR CONDS EXPECTED MOST OF THE DAY THURSDAY. COULD SEE
SOME ADDITIONAL CONVECTIVE DEVELOPMENT TOMORROW AFTERNOON BUT

.PREV UPDATE...
.UPDATE...
HAVE REMOVED EVERYONE ALONG AND NORTH OF A GOLDTHWAITE...HILLSBORO...ATHENS
LINE OUT OF THE SEVERE THUNDERSTORM WATCH 365...BUT ADDED/EXTENDED THOSE
AREAS TO THE SOUTH OF THAT TIL MIDNIGHT...ESPECIALLY WITH INSTABILITY
UNTAPPED AND TAIL-END OF FORCING FROM SHORTWAVE MOVING ACROSS...AS EVIDENCED
BY LONG-LASTING SUPERCELL MOVING INTO BELL COUNTY. SOME ELEVATED INSTABILITY
IS INDUCING SOME WIDELY SCT/ELEVATED ACTIVITY BACK OVER WRN COUNTIES
ON AFOREMENTIONED LIFT...BUT WORST SHOULD BE SOME LIGHTNING AND POSSIBLE
SMALL HAIL WITH ANY RESIDUAL...LINGERING ACTIVITY OVERNIGHT.

05/

&&

.PREV DISCUSSION... /ISSUED 322 PM CDT WED JUN 10 2009/
THUNDERSTORMS WILL BECOME MORE NUMEROUS ACROSS NORTH TEXAS LATE
THIS AFTERNOON AND THIS EVENING AS A COLD FRONT APPROACHES FROM THE
NORTHWEST. THE LATEST SPC MESOANAYSIS SHOWS THE CAP HAS JUST ABOUT
LIFTED ACROSS THE ENTIRE REGION AND SURFACE BASED CAPE REMAINS BETWEEN
2000 AND 3500 J/KG. THE BEST CHANCE OF SEVERE STORMS WILL BE IN
THE NORTHWEST ZONES WHERE SURFACE CONVERGENCE WILL BE MAXIMIZED
ALONG THE COLD FRONT. EXPECT THUNDERSTORMS TO CONTINUE INTO THE
OVERNIGHT HOURS...ESPECIALLY IN THE NORTHERN ZONES. AT THIS TIME
IT APPEARS THAT HAIL WILL BE THE PRIMARY SEVERE WEATHER THREAT.
HOWEVER...A DRY LAYER BETWEEN 900 AND 700 MB SHOULD ALSO PROMOTE
EVAPORATIVE COOLING AND DOWNBURST WIND POTENTIAL.

THE COLD FRONT IS FORECAST TO WEAKEN AND LIFT NORTHWARD THURSDAY
WITH A FEW LINGERING SHOWERS AND THUNDERSTORMS...ESPECIALLY ACROSS THE
NORTHERN HALF OF THE REGION. THE NAM CONTINUES TO INDICATE A SHORT
WAVE THURSDAY NIGHT WITH SCATTERED THUNDERSTORMS IN THE EAST. THE
GFS IS MUCH WEAKER WITH THIS FEATURE...BUT BASED ON THE
FORECASTED INSTABILITY...WILL KEEP CHANCE POPS IN THE FORECAST.

WARMER AIR AND RAIN-FREE CONDITIONS ARE EXPECTED THIS WEEKEND
THROUGH THE FIRST HALF OF NEXT WEEK AS UPPER LEVEL HIGH PRESSURE
STRENGTHENS OVER THE REGION. UNFORTUNATELY...LOW LEVEL HUMIDITY
WILL REMAIN HIGH AND AFTERNOON HEAT INDEX VALUES WILL SURPASS THE
CENTURY MARK IN MANY LOCATIONS...ESPECIALLY EARLY NEXT WEEK.

LOOKING AHEAD...IT APPEARS THE UPPER RIDGE WILL BE SLOW TO DEPART
AND WARM/HUMID/RAIN-FREE CONDITIONS WILL PERSIST THROUGH NEXT WEEKEND.
