.DISCUSSION...
REFER TO FOLLOWING AVIATION DISCUSSION.

&&

.AVIATION...
AN MVFR CIG COULD FORM OVER THE SOUTHERN TERMINALS BETWEEN 12 AND
15Z FOR BRADY... JUNCTION... SONORA...AND TO A LESSER EXTENT SAN
ANGELO. CALM TO VERY LIGHT EAST TO NORTHEAST WINDS WILL INCREASE
TO 5 TO 10 MPH BY NOON AS A SURFACE RIDGE OF HIGH PRESSURE FROM
THE NORTHEAST CONTINUES TO BUILD INTO WC TX. AFTER A BRIEF PERIOD
OF LOW CLOUDS...CIGS SHOULD BECOME SCT AFTER 15Z TODAY AS MOSTLY VFR
CONDITIONS PREVAIL THRU 12Z FRI.

&&

.PREV DISCUSSION... /ISSUED 334 AM CDT THU SEP 25 2008/

SHORT TERM...
PERSISTENCE RULES ACROSS WEST CENTRAL TEXAS...AS UPPER HIGH
REMAINS JUST OFF TO THE WEST AND THE AIR MASS PRETTY MUCH REMAINS
THE SAME. GOT SURPRISED BY A FEW SHOWERS ACROSS THE BIG COUNTRY
AND CONCHO VALLEY ON WEDNESDAY...BUT SIGNATURE NOT QUITE THE SAME
THIS MORNING. CAN NOT RULE OUT A STRAY SHOWER OR STORM...
ESPECIALLY ACROSS THE NORTHERN EDWARDS PLATEAU...BUT CHANCES SMALL
ENOUGH TO NOT MENTION IN THE ZONES THEMSELVES. OTHERWISE...LOW
LEVEL TEMPERATURE FIELDS SHOW LITTLE CHANGE...GUIDANCE NUMBERS
ABOUT THE SAME...STICKING REAL CLOSE TO PERSISTENCE SEEMS LIKE A
GOOD BET.

LONG TERM...
SEE PERSISTENCE STATEMENTS ABOVE...BUT RIDGE NOT GOING ANYWHERE
SOON SO CHANGES IN SENSIBLE WEATHER WILL BE SMALL. HAVE ADJUSTED
OVERNIGHT LOWS DOWN A TAD...AS SLIGHTLY DRIER AIR MASS SHOULD
ALLOW FOR SLIGHTLY BETTER RADIATIONAL COOLING. RIDGE FINALLY BEGINS
TO BREAK DOWN SOME BY THE MIDDLE OR END OF NEXT WEEK...WHICH
SHOULD ALLOW A FAIRLY WEAK COLD FRONT TO DROP INTO THE AREA. HAVE
COOLED TEMPERATURES A FEW DEGREES FOR THE END OF THE EXTENDED.
