.DISCUSSION...
RAISED DAYTIME TEMPS A TAD AS LOW LVL SPEED AND DIRECTIONAL SHEAR
IN LOW LVL SOUTHERLY FLOW INDICATING STRONG WARM AIR ADVECTION. 
HOWEVER...CLOUDY SKIES WILL CONTINUE TO PREVAIL THIS AFTN WITH
SPOTTY SHOWERS DEVELOPING WITH INCREASING ISENTROPIC LIFT...EXPECT
RAIN TO BE FAIRLY LIGHT AND MOSTLY CONCENTRATED LATER IN
AFTN...TOWARDS EVENING./VII/

&&

.AVIATION...
CONDITIONS ARE EXPECTED TO GRADUALLY DETERIORATE THROUGH THE 
FORECAST PERIOD.  MOST SITES ARE SEEING VFR FLIGHT CATEGORIES...WITH 
THE EXCEPTION OF A FEW EAST TEXAS SITES SEEING PERIODS OF MVFR CIGS. 
CIGS WILL BE DECREASING THROUGH THE DAY TO GIVE PREVAILING MVFR CIGS 
FOR EAST TEXAS SITES BY THIS AFTERNOON AND GRADUALLY SPREADING NORTH 
AND EAST.  BY 18Z LIGHT RAIN WILL BEGIN TO DEVELOP ACROSS EAST TEXAS 
SITES AND SPREAD NORTHEAST ACROSS THE REMAINING SITES THIS EVENING.  
PERIODS OF LIGHT RAIN SHOULD CONTINUE THROUGH MUCH OF THE FORECAST 
PERIOD...BEGINNING TO DECREASE OVER EAST TEXAS SITES BY AROUND 
SUNRISE MONDAY MORNING.  LOW LEVEL MOISTURE AND LIGHT WINDS MAY LEAD 
TO FOG DEVELOPMENT DURING THE EARLY MORNING HOURS FOR MOST SITES. 
FLIGHT CATEGORIES COULD DIP DOWN TO IFR AND POSSIBLY LIFR AT TIMES 
AS A RESULT.  THESE CONDITIONS SHOULD IMPROVE AFTER SUNRISE.  
OTHERWISE EXPECT LIGHT WINDS OUT OF THE SOUTHEAST TO SWITCH AROUND 
TO THE NORTH TOWARD THE END OF THE FORECAST PERIOD. /22/
