.SHORT TERM...
THE AIRMASS REMAINS MOIST AND UNSTABLE ACROSS THE ENTIRE CWFA THIS
AFTERNOON...AND SCATTERED CONVECTION CONTINUES ACROSS MUCH OF THE
WESTERN HALF OF THE CWFA.  THESE STORMS ARE EXPECTED TO BE OF THE
MULTICELL PULSE VARIETY AS DEEP LAYER SHEAR IS WEAK...BUT LOCALLY
HEAVY RAINFALL IS A POSSIBILITY GIVEN STORM VELOCITIES NEAR 5 M/S
AND PRECIPITABLE WATER VALUES IN EXCESS OF 3 CM.  THE SCATTERED
NATURE OF THIS CONVECTION PRECLUDES A WIDESPREAD FLASH FLOOD THREAT
AND THUS WE WILL NOT ISSUE A WATCH...HOWEVER...WE HAVE MENTIONED
THIS THREAT IN THE HWO.

CONVECTION SHOULD BEGIN TO DISSIPATE SHORTLY AFTER SUNSET AS THE
COMBINATION OF SPREADING COLD POOLS AND SENSIBLE HEATING LOSS
COMBINE TO STABILIZE THE PBL.  THERE WILL BE CONSIDERABLE MID AND
HIGH LEVEL MOISTURE PRESENT OVERNIGHT...AND WITH A NEARLY MOIST
ADIABATIC PROFILE...LITTLE LIFT IS NEEDED TO MAINTAIN AT LEAST
ELEVATED SHOWERS.

THE GFS CONTINUES TO EXHIBIT A WARM BIAS FOR OVERNIGHT LOWS...
CONSEQUENTLY WE WILL TREND THE MIN TEMPERATURE AND DEWPOINT GRIDS
TONIGHT STRONGLY TOWARD PERSISTENCE.  POP...SKY...AND ASSOCIATED
SENSIBLE WEATHER GRIDS WERE DRAWN TO REFLECT CHANCE CATEGORY POPS
FROM SOUTHEASTERN NEW MEXICO SOUTH INTO THE BIG BEND...THEN TAPERING
OFF TO SLIGHT CHANCE/ISOLATED CATEGORY ACROSS FAR EASTERN ZONES
THIS EVENING.  THE GFS APPEARS TO BE HAVING SOME CONVECTIVE
FEEDBACK ISSUES OVER FAR WESTERN ZONES AFTER MIDNIGHT...AND WHILE
WE EXPECT ISOLATED CONVECTION JUST ABOUT ANYWHERE EARLY MONDAY
MORNING...QPF WAS SCALED BACK CONSIDERABLY OVER WHAT THE GFS
SUGGESTS.  LASTLY...WIND GRIDS REFLECT THE NAM12 FORECAST AVERAGED
WITH A BLEND OF NAM AND GFS MOS GUIDANCE THEN TEMPERED A BIT FOR
LOCAL EFFECTS.

.LONG TERM...
UPPER LEVEL RIDGE CONTINUES OVER THE CWA WITH WEAK A SHEAR AXIS AND
THETA-E RIDGE OVER THE WESTERN PART OF THE REGION.  BY MONDAY
EVENING THE THETA-E RIDGE WILL BEGIN TO MOVE TO THE WEST AS THE
UPPER LEVEL RIDGE STRENGTHENS OVER THE REGION.

WILL CARRY CHANCE POPS OVER THE GUADALUPE MOUNTAINS WITH SLIGHT
CHANCE POPS OVER THE ADJACENT PLAINS AND THE DAVIS MOUNTAINS.
ISOLATED THUNDERSTORMS CAN BE EXPECTED OVER THE EASTERN HALF OF THE
CWA.  BY MONDAY NIGHT THE POPS WILL BE MOVED TO THE MOUNTAINOUS AREAS
WITH MORE ISOLATED CONVECTION EXPECTED OVER THE REMAINDER OF THE
AREA.  BY TUESDAY...THE PRECIPITATION CHANCES WILL DECREASE TO
ISOLATED AFTERNOON CONVECTION OVER THE MOUNTAINS AS THE THETA-E
RIDGE CONTINUES TO MOVE TO THE WEST.  DRY WEATHER IS INDICATED IN
THE PLAINS TUESDAY THROUGH SUNDAY.

TEMPERATURES WILL REMAIN CLOSE TO NORMAL THROUGH THE WEEK WITH A
VERY SLOW WARMING TREND EXPECTED.  MOST HIGHS WILL BE IN THE 90S
WITH 80S OVER THE HIGHER ELEVATIONS.  LOWS WILL BE MAINLY IN THE
60S WITH A FEW 70S ALONG THE BORDER.
