.SHORT TERM...
DRYLINE IS FINALLY MIXING EAST ACROSS WESTERN PORTIONS OF THE SPLNS
AND PERMIAN BASIN...WITH A BIT OF A BULGE SOUTH OF OUR CWA AS
STRONGER WESTERLY MOMENTUM IS MIXING DOWN IN THAT AREA. WV IMAGERY
AND AREA PROFILERS SHOW A SHARP MID/UPR LEVEL TROUGH MOVING ACROSS
NM AND FAR WTX. LIFT FROM THIS TROUGH WILL OVERSPREAD THE AREA THIS
AFTN AND EVE. HOWEVER...THIS LIFT IS ACCOMPANIED BY CONSIDERABLE
CIRRUS SHIELD THAT WILL PLAY SOME ROLE IN RETARDING FURTHER
MIXING/HEATING. 18Z AMA/MAF SNDGS AND WTXM MESONET SNDG FROM REESE
SHOW POTENTIAL FOR SUPERCELLS EAST OF THE DRYLINE WITH LARGE CAPE
AND DECENT SHEAR...WHICH SHOULD BE INCREASING THIS EVE AS LOW-LVL
SRLY WINDS INCREASE. CAP DOES INCREASE FURTHER SOUTH AND MAY LIMIT
DEVELOPMENT SOUTH OF AROUND LBB LATITUDE. BEST FOCUS FOR TSTMS STILL
APPEARS TO BE ACROSS THE NRN ROLLING PLAINS...WITH LOWER
POTENTIAL FURTHER TO THE SOUTH OFF THE CAPROCK. STORMS THAT
DEVELOP WILL HAVE TO POTENTIAL TO QUICKLY BECOME SVR AND EVEN
PRODUCE AN ISOLD TORNADO ACROSS THE FAR EASTERN COUNTIES. PLEASE
SEE MORE INFO ON SVR POTENTIAL VIA HWOLUB...AND SPC PRODUCTS.

TROUGH AXIS MOVES EAST OVERNIGHT AND SHOULD END TSTM THREAT BY MIDN.
WINDS WILL SLOWLY VEER FROM SW TO NW SUN MORN AND MAY BE A BIT GUSTY
IN THE MORN HRS BEFORE GRADUALLY DIMINISHING. DRY AIR WILL CONTINUE
TO ADVECT IN AND WIND/RH MAY APPROACH RED FLAG CONDITIONS ACROSS THE
CAPROCK BY MIDDAY...HOWEVER FCST WIND SPEEDS DO NOT APPEAR TO BE
STRONG ENOUGH FOR ANY HIGHLIGHTS ATTM.

.LONG TERM...
COLD FRONT IS EXPECTED TO SLIDE INTO WEST TEXAS SUNDAY NIGHT
BRINGING COOLER EASTERLY WINDS. TEMPERATURES ARE EXPECTED TO FALL
BACK INTO THE 70S ON MONDAY THEN A GRADUAL WARMING TREND AS WE SEE
SOME GULF MOISTURE RETURN IN ADVANCE OF THE NEXT PIECE OF JET
ENERGY. WE COULD SEE SOME WARM ADVECTION SHOWERS/THUNDERSTORMS AS
EARLY AS TUESDAY NIGHT BUT BETTER CHANCES WILL BE WEDNESDAY ALONG
AND EAST OF THE DRYLINE. THE DRYLINE SHOULD SET UP SOMEWHERE NEAR
THE EASTERN EDGE OF THE CAPROCK. WE WILL ONCE AGAIN SEE SOME
STRONGER WINDS AS THE ENERGY MOVES INTO THE PLAINS ON THURSDAY.
THIS COULD LEAD TO SOME FIRE WEATHER CONCERNS BUT PLENTY OF TIME
TO EVALUATE THIS POTENTIAL. ANOTHER BRIEF COOL DOWN INTO THE 70S
FOR THURSDAY BUT WARMING AGAIN FOR THE END OF THE WEEK INTO NEXT
WEEKEND.
