WV IMAGERY SHOWS AN UPPER TROUGH EXTENDING FROM THE TEXAS COAST UP  
THRU THE MS VALLEY, LEAVING WEST TEXAS AND SOUTHEAST NEW MEXICO  
UNDER MERIDIONAL FLOW ALOFT. OVER THE NEXT FEW DAYS, MODELS ARE IN  
LINE IN STRENGTHENING THE TROUGH, AND TAKING IT TO THE ARKLATEX BY  
06Z SUN. DESPITE THIS, THICKNESSES ARE SET TO INCREASE THRU SUNDAY  
AS THE WEST COAST RIDGE TRIES TO NUDGE IN BEHIND THE TROUGH. SUNDAY  
SHOULD BE THE WARMEST DAY THIS FORECAST, AS 850MB TEMPS INCREASE TO  
NEAR 30C MOST LOCATIONS. THE NAM12 EVEN SUGGESTS KMAF AND A FEW  
OTHER PLACES IN THE PERMIAN BASIN/PECOS RVR VALLEY COULD BREAK THE  
CENTURY MARK ONE LAST TIME THIS FALL...ALTHOUGH THIS IS AN OUTLIER  
AND WE PROBABLY WON'T BE SO LUCKY. STILL, HIGHS 2-3 STD DEVS ABOVE  
NORMAL CAN BE EXPECTED.  
 
REGRETTABLY, THIS COMES TO AN END SUNDAY NIGHT AS A STRONG COLD  
FRONT DROPS IN BEHIND THE EXITING TROUGH. THIS WON'T BE QUITE AS  
STRONG AS THE ONE A FEW WEEKS AGO, BUT STRONG ENOUGH TO KNOCK HIGHS  
MONDAY AFTERNOON DOWN WELL-BELOW NORMAL, MAKING IT FEEL MORE LIKE  
MID-OCTOBER THAN LATE SEPTEMBER. A FEW HOURS OF HIGH GAP WINDS AT  
KGDP LOOK LIKELY, AND WE'LL MENTION THIS IN THE HWO. DESPITE ITS  
STRENGTH, THE FRONT WILL BE SHORT-LIVED, W/RETURN FLOW RESUMING MON  
NIGHT AND TEMPS REBOUNDING TO ABOVE-NORMAL TUE AFTERNOON. WED LOOKS  
SIMILAR TO TUE, BUT A SECONDARY COLD FRONT WED NIGHT SHOULD TAKE  
TEMPS THU BELOW NORMAL AGAIN.  
 
INCREDIBLY THOUGH ALL THIS, RAIN CHANCES LOOK SLIM-TO-NONE, AND SLIM  
IS TRYING TO LEAVE THE BUILDING. SOME ISOLATED CONVECTION IS  
EXPECTED LATER THIS AFTERNOON ON THE MARFA PLATEAU AS A WEAK  
DISTURBANCE MOVES SOUTH THRU THE AREA, AND TOWERS CAN BE SEEN GOING  
UP ALREADY ON VIS SATELLITE. OTHERWISE, THE TWO UPCOMING COLD  
FRONTS LOOKS DRY, W/NOT MUCH MOISTURE TO WORK WITH. THE  
CANADIAN/ECMWF GENERATE A LITTLE CONVECTION ON THE FIRST FRONT SUN  
NIGHT, KEEPING THE BULK OF CONVECTION EAST IN THE BETTER MOISTURE.  
BUT THE GFS IS DRY, AND WE'LL KEEP THE GRIDS DRY FOR NOW UNTIL  
MODELS COME INTO BETTER AGREEMENT AND/OR INCREASE CHANCES.
