AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
1252 PM CDT MON APR 30 2007

.AVIATION...JUST PRETTY MUCH AN UPDATE TO THE PREVIOUS PACKAGE.
DID NOT MENTION THUNDERSTORMS AT KSJT...BUT CAN NOT RULE THEM OUT
AT THIS TIME...BUT CHANCES ARE LESS THAN 50 PERCENT OF HITING THE
TERMINAL. OTHERWISE TAFS ARE THE SAME WITH MENTION OF
STORMS...MAINLY AFTER 22 TO 23 Z.

&&

.PREV DISCUSSION... /ISSUED 1112 AM CDT MON APR 30 2007/

UPDATE...FLASH FLOOD WATCH WAS CANCELLED A LITTLE EARLY AS
WIDESPREAD THUNDERSTORMS HAVE EXITED OFF TO THE SOUTHEAST.
ADDITIONAL THUNDERSTORMS ARE FORECAST TO DEVELOP THIS AFTERNOON
WITH SOME PARTIAL CLEARING...ATMOSPHERE SHOULD DESTABILIZE ONCE
AGAIN THIS AFTERNOON...IN ADDITION ANOTHER LOBE OF VORTICITY IS
FORECAST TO ROTATE AROUND THE MAIN UPPER LOW THIS AFTERNOON AND
EVENING AND WE ARE CONTEMPLATING ANOTHER FFA FOR THE NORTHERN
COUNTIES THIS AFTERNOON AND EVENING...BUT THUNDERSTORMS MAY BE
MORE SCATTERED AND THUS LIMIT THE FLOODING POTENTIAL. LOOKING
OUTSIDE WE HAVE SOME MODERATE CU BEGINNING TO DEVELOP TO THE WEST
AND WE SHOULD BEGIN TO SEE NEW THUNDERSTORMS DEVELOP SHORTLY.
CAPES FORECAST TO GET BACK INTO THE 1500 TO 2000 J/KG THIS
AFTERNOON AND SOME MODERATE SHEAR WILL LIKELY SEE ISOLATED SEVERE
THUNDERSTORMS DEVELOP AGAIN THIS AFTERNOON.

BRAZZELL

PREV DISCUSSION... /ISSUED 717 AM CDT MON APR 30 2007/

UPDATE...
OPTED TO EXTEND THE FLASH FLOOD WATCH FOR THE REMAINDER OF THE
MORNING ACROSS THE NORTHWEST HILL COUNTRY AND THE NORTHERN EDWARDS
PLATEAU. ALTHOUGH THE MAIN CONVECTIVE COMPLEX CONTINUES TO WEAKEN
AND SHIFT EAST...NEW DEVELOPMENT CONTINUES TO TAKE PLACE TO THE
WEST. HEAVY RAINFALL LOOKS MORE SPOTTY...BUT GIVEN THE RAINFALL
FROM EARLIER TONIGHT...EXTENDING THE WATCH LOOKS PRUDENT.

PREV DISCUSSION... /ISSUED 631 AM CDT MON APR 30 2007/

AVIATION...
COMPLEX OF SHOWERS AND STORMS CONTINUES TO PUSH EAST EARLY THIS
MORNING...WITH NEW STORMS DEVELOPING TO THE SOUTHWEST ACROSS
PORTIONS OF THE NORTHERN EDWARDS PLATEAU. FOR THE TAF SITE SEEING
THE PRECIP SHIELD TO START THE MORNING OFF...KABI...KJCT...KBBD...
CEILINGS FOR THE MOST PART WILL BE IN THE VFR RANGE...BUT DID
INCLUDE A TEMPO DURATION THROUGH THE NEXT FEW HOURS FOR AN MVFR
CEILING AND VISIBILITY.

ONCE THE MAIN BAND GOES BY...THINGS DRY OUT A LITTLE. SCATTERED
SHOWERS AND STORMS WILL LIKELY DEVELOP OFF AND ON JUST ABOUT
ANYWHERE ACROSS THE AREA THE REMAINDER OF TODAY AND INTO THE
EVENING. BEST WAY TO HANDLE THIS ACTIVITY SEEMS TO BE WITH
WIDESPREAD VCTS MENTION IN THE TERMINALS...BUT WILL CONTINUE TO
WATCH RADAR TRENDS AND AMENDMENTS ARE LIKELY.

PREV DISCUSSION... /ISSUED 327 AM CDT MON APR 30 2007/

SHORT TERM...
FIRST OF ALL...THE TORNADO WATCH. AFTER DISCUSSION WITH SPC...THE
TORNADO WATCH THAT HAD BEEN IN EFFECT UNTIL 3 AM WAS ALLOWED TO
EXPIRE...AND THE NEW SEVERE THUNDERSTORM WATCH WAS KEPT JUST TO
THE SOUTHEAST. ALREADY EXTENDED THE FLASH FLOOD WATCH FOR THE
EASTERN COUNTIES THROUGH 7 AM. GIVEN THE STEADY EASTWARD PROGRESS
OF THE CONVECTIVE SYSTEM...HEAVIEST RAIN MAY BE EXITING MY
COUNTIES RIGHT AT 12Z. WITH THE ATMOSPHERE BEHIND THE COMPLEX AT
LEAST SOMEWHAT WORKED OVER...SHOULD SEE A BREAK IN MUCH OF THE
SHOWERS AND THUNDERSTORMS FOR AWHILE TODAY. MAY SEE SOME RECOVERY
THIS AFTERNOON...BUT WILL STILL UNDERCUT GUIDANCE POPS FOR THE
CENTRAL AND WESTERN SECTIONS OF WEST CENTRAL TEXAS TODAY.

STILL EXPECT SCATTERED CONVECTION TO DEVELOP ACROSS PORTIONS OF
WEST CENTRAL TEXAS...AT LEAST UNTIL THE UPPER LOW CAN EXIT ON
TUESDAY NIGHT.

LONG TERM...
NOT MUCH CHANCE TO LOOK AT ANYTHING OTHER THAN THIS FIRST SYSTEM.
NEXT UPPER LOW STILL LOOKS ON PACE TO MOVE INTO THE AREA FOR
WEDNESDAY NIGHT AND THURSDAY. WILL UNDERCUT GFS GUIDANCE TEMPS
SOME LATE IN THE WEEK. ENSEMBLE NUMBERS ARE GENERALLY A FEW
DEGREES COOLER...AND WILL HAVE TO DRY OUT THE WET GROUND FIRST.
