.PREV DISCUSSION... /ISSUED 742 AM CST FRI DEC 19 2014/

AVIATION...
A WIDE RANGE OF FLIGHT CATEGORIES ACROSS THE PANHANDLES FOR THE START
OF THE 12Z TAF ISSUANCE. LOWEST CATEGORY GOES TO KAMA WITH LIFR
CONDITIONS AS EARLY MORNING SHOWERS BEGIN TO MOVE EAST OF THE
TERMINAL. THE DEPARTURE HAS ALLOWED CEILINGS AND VISBI TO DROP
SLIGHTLY. KDHT FOLLOWS CLOSELY WITH IFR CONDITIONS HOWEVER...KDHT IS
NEAR THE CLEARING LINE OF UPPER LEVEL CLOUDS WHICH HAS ALLOWED THE
LOWER DECK TO EXPAND/LOWER. WOULD NOT BE SURPRISED TO SEE A DROP TO
LIFR WITHIN THE FIRST HOUR OR TWO OF THE TAF ISSUANCE FOLLOWED BY GRADUAL
IMPROVEMENT. KGUY IS THE BEST OFF WITH MVFR CONDITIONS BUT IS RIGHT
ON THE FENCE BETWEEN MVFR AND IFR. AS THE UPPER TROUGH MOVES EASTWARD
EARLY THIS MORNING CAN NOT RULE OUT A BRIEF DROP TO IFR.

THE FIRST 6 HOURS OF THE TAF ISSUANCE SHOULD SEE IMPROVEMENT AT EACH
TERMINAL TO MVFR/VFR. GIVEN THE AMOUNT OF LOW LEVEL MOISTURE ACROSS
THE SOUTHERN TEXAS PANHANDLE...KAMA MAY STAY AT MVFR THROUGH THE
DAYLIGHT HOURS. KDHT AND KGUY WILL HAVE THE BEST CHANCES TO REACH VFR
AROUND NOON.

OVERNIGHT WE COULD SEE ANOTHER ROUND OF LOW CEILINGS/VISBI TO IMPACT
THE TERMINALS GIVEN AMPLE LOW LEVEL MOISTURE SITUATED ACROSS THE
PANHANDLES.
