AVIATION DISCUSSION...
NO AVIATION WEATHER CONCERNS FOR THE NEXT 24 HOURS.  SHOWERS AND 
THUNDERSTORMS OVER EAST TEXAS SHOULD DISSIPATE WELL BEFORE 
REACHING WACO.  EXPECT CU TO DISSIPATE BY SUNSET WITH WINDS 
DECREASING TO AROUND 8KTS.  BY THURSDAY MORNING...EXPECT WINDS TO 
BECOME MORE SOUTHWEST AS SURFACE RIDGE SLIDES TO THE EAST IN ADVANCE 
OF APPROACHING HIGH PLAINS TROUGH.  WILL KEEP SPEEDS AROUND 12 KTS 
THURSDAY WITH A FEW CU DURING THE AFTERNOON.

AFTERNOON FORECAST DISCUSSION

NEW FORECAST WILL BE VERY SIMILAR TO OLD ONE AS HIGH PRESSURE
CONTINUES TO KEEP N TEXAS HOT AND DRY. THERE IS A SLIGHT CHANCE THAT
A WEAK BOUNDARY (PRE-FRONTAL TROUGH/WEAK COLD FRONT) WILL MOVE CLOSE
ENOUGH TO NORTH TEXAS TO BRING A FEW AFTERNOON SHOWERS OR
THUNDERSTORMS TO THE RED RIVER COUNTIES ON FRIDAY. ETA AND AVN PRETTY
MUCH AGREE ON THIS FEATURE...WITH THE AVN DRIVING IT A BIT FURTHER
SOUTH INTO LA. H5 HIGH POSITION WILL NOT CHANGE A WHOLE LOT...SO
MAIN PUSH OF FRONT/TROUGH WILL BE EAST OF N TEXAS. OTHERWISE...
THERE IS SOME QUESTION ON THE NEED FOR A HEAT ADVISORY THE NEXT 2
DAYS. MODELS CONTINUE TO INDICATE SOME DRYING OF THE AIRMASS IN THE
LOWEST LAYERS AS FETCH OFF GULF WILL BE DIRECTED MORE EASTERLY BEFORE
FINALLY SHIFTING NORTH. THE DRIER AIR SHOULD ALLOW LOWS TO DROP INTO
THE MID 70S MOST AREAS AND KEEP AFTERNOON RH LOW ENOUGH WHERE THE THI
REMAINS MINIMAL. STILL...IT WILL BE HOT...WITH HIGHS FROM 100 TO 103
IN MOST AREAS. HARD TO BEAT NGM MOS BUT WITH DRIER AIR ON FRIDAY...
WILL GO ABOVE MOS AND KEEP HIGHS AROUND 100. 80
