AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
235 PM CDT WED SEP 1 2004

.SHORT TERM...
UPPER LEVEL CIRCULATION...WHATS LEFT OF THE MCV...CONTINUES OVER
THE CWFA THIS AFTERNOON.  WESTERN AREAS ARE GETTING POPCORN
CONVECTION ATTM WHILE THE EAST REMAINS DRY.  COULD BE A WEAK
SUBSIDENT AREA AND THERE IS SOME DRIER AIR AT THE SURFACE WORKING
ITS WAY INTO THE EASTERN CWFA...THEREBY LIMITING CAPE.  BUT THIS
AREA IS GETTING GOOD INSOLATION...AND THUS EXPECT THAT SCATTERED
CONVECTION WILL DEVELOP OVER THE PERMIAN BASIN AND WESTERN LOW
ROLLING PLAINS IN THE NEXT FEW HOURS.  CONVECTION SHOULD BEGIN TO
DIMINISH LATER THIS EVENING AS THE PBL STABILIZES WITH LOSS OF
SENSIBLE HEAT AND ADDITION OF CONVECTIVELY GENERATED COLD POOLS.

OVERALL...GRIDS WERE IN GOOD SHAPE WITH MINOR ADJUSTMENTS NEEDED
HERE AND THERE.  MODELS DEPICT A DRY BIAS IN THEIR TD FORECASTS
TONIGHT AND HAVE ADJUSTED UPWARD GIVEN CURRENT CONDITIONS.  WILL
MENTION HEAVY RAIN IN THE HWO BUT ATTM BELIEVE THE THREAT TO BE
SUFFICIENTLY ISOLATED IN TIME AND SPACE TO PRECLUDE A FLASH FLOOD
WATCH.

.LONG TERM...
WV IMAGERY TODAY SHOWS THE MID/UPPER LEVEL CIRCULATION OVER THE TOP
OF WEST TX/SOUTHEASTERN NM THIS AFTERNOON.  THIS FEATURE WILL SLOWLY
DRIFT TO THE SOUTH/SOUTHEAST THROUGH THE DAY ON THURSDAY.  DURING THE
MORNING HOURS...ENOUGH OF THIS CIRCULATION WILL IMPACT THE BIG
BEND/DAVIS MOUNTAINS AREAS TO JUSTIFY RAISING THE POPS INTO AT LEAST
THE SLIGHT CHANCE CATEGORY WITH THE HIGHEST POPS OVER THE BIG BEND
ITSELF.  AFTER THURSDAY...THIS MID LEVEL CIRCULATION SHOULD MOVE AWAY
FROM THE AREA LEAVING US UNDER WEAK SOUTHWESTERLY FLOW.  WILL NOT
CHANGE POPS MUCH AFTER TOMORROW.  WE COULD SEE SOME SHORTWAVES MOVE
THROUGH IN THE SOUTHWEST FLOW...BUT TIMING THESE SHORTWAVES IS
PROBLEMATIC AT THIS POINT.

BY SUNDAY A STRONG TROUGH IS ESTABLISHED OVER THE ROCKY MOUNTAINS.
THE 12Z GFS HAS BECOME MORE PROGRESSIVE IN ITS SOLUTION COMPARED TO
OLDER GFS/ECMWF RUNS AND THE NEW 12Z ETA.  THEREFORE WE WILL NOT USE
THE 12Z GFS AS THE SOLUTION UNTIL THERE IS MORE AGREEMENT BETWEEN
THE MODELS.  CONSEQUENTLY...THE FORECAST WILL NOT CHANGE MUCH BEYOND
THIS WEEKEND.  WILL KEEP THE ISOLATED POPS OVER THE CWA ASSOCIATED
WITH A POSSIBLE FRONT AS THE TROUGH MOVES EAST ACROSS THE PLAINS...
BUT IT/S STILL TOO EARLY TO MAKE TOO MANY CHANGES CONSIDERING THE
MODEL DIFFERENCES.  DID MAKE SOME ADJUSTMENTS TO TEMPERATURES HERE
AND THERE TO MORE CLOSELY MATCH CLIMATOLOGY BEYOND DAY 4.  ANOTHER
CONSIDERATION AS THE ROCKY MOUNTAIN TROUGH DOES EVENTUALLY MAKE ITS
WAY TO THE EAST WILL BE WINDS IN THE GUADALUPE MOUNTAINS.  IF THE
TROUGH TAKES A MORE SOUTHERN TRACK...WE COULD HAVE FAIRLY WINDY
CONDITIONS IN THE GUADALUPES.  WILL HAVE TO KEEP AN EYE ON THIS AS
WE APPROACH THAT TIME PERIOD.

THE NATIONAL WEATHER SERVICE IN MIDLAND HAS RECEIVED REPORTS OF
FUNNEL CLOUDS IN CENTRAL AND SOUTHERN LEA COUNTY IN VICINITY OF
DEVELOPING STRONG THUNDERSTORMS. NATIONAL WEATHER SERVICE DOPPLER
RADAR IS DETECTING SCATTERED THUNDERSTORMS DEVELOPING ACROSS
SOUTHEAST NEW MEXICO AND THE UPPER TRANS PECOS REGION OF WEST TEXAS.
THIS ACTIVITY WILL PERSIST THROUGH THE REMAINDER OF THE AFTERNOON AND
INTO THE EVENING HOURS.

THE AIRMASS ACROSS WEST TEXAS AND SOUTHEASTERN NEW MEXICO IS MOIST
AND UNSTABLE. BECAUSE THE AIRMASS IS SO MOIST...TROPICAL FUNNEL
CLOUDS MAY DEVELOP UNDERNEATH THESE STORMS.

TYPICALLY...TROPICAL FUNNELS ARE SHORT-LIVED AND RARELY LAST LONGER
THAN TEN MINUTES. THEY ARE ALSO SMALL AND GROW TO PERHAPS TEN OR
TWENTY YARDS IN DIAMETER. ON RARE OCCASIONS...THESE FUNNEL CLOUDS DO
TOUCH THE GROUND AND BRIEFLY BECOME TORNADOES. WIND SPEEDS ASSOCIATED
WITH TROPICAL FUNNEL CLOUDS ARE GENERALLY UNDER 60 MPH...COMPARABLE
TO A STRONG DUST DEVIL...AND CAN DAMAGE LIGHTWEIGHT STRUCTURES SUCH
AS CARPORTS AND AWNINGS. SINCE THESE TROPICAL FUNNELS ARE BRIEF...
SMALL...AND RELATIVELY WEAK...THEY ARE VIRTUALLY IMPOSSIBLE TO DETECT
WITH DOPPLER RADAR.

ALONG WITH THE TROPICAL FUNNEL CLOUDS...GUSTY WINDS AND DEADLY CLOUD
TO GROUND LIGHTNING MAY ACCOMPANY THESE STORMS. SEEK SAFE SHELTER IF
THREATENING WEATHER APPROACHES YOUR LOCATION.

STAY TUNED TO NOAA WEATHER RADIO...COMMERCIAL TELEVISION OR RADIO
STATIONS...OR YOUR CABLE TELEVISION PROVIDER FOR THE LATEST IN
WEATHER INFORMATION.
