AVIATION...
TOUGH AVIATION FORECAST TONIGHT...AND IT LOOKS LIKE IT IS NOT GOING
TO GET ANY EASIER OVER THE NEXT SEVERAL DAYS. DENSE FOG ALONG WITH
LOW CEILINGS (LIFR/VLIFR) COVER ALMOST THE ENTIRE AREA WITH IMPROVED
UNRESTRICTED CEILINGS AND VISIBILITIES JUST TO OUR WEST. DECIDED TO
KEEP FOG AND CEILINGS IN THE 06Z TAFS WITH IMPROVEMENT COMING AFTER
SUNRISE. IT IS QUITE POSSIBLE THAT THINGS WILL GET BETTER OUT WEST
AS DRIER AIR CONTINUES TO EDGE THIS WAY...BUT NOT CONFIDENT TO INCLUDE
IT IN THE TAFS AT THIS TIME. FOG SHOULD LIFT AREA WIDE (EXCEPT IN/AROUND
GALVESTON BAY AREA) IN THE MORNING. WE THEN ARE INCLUDING VCSH STARTING
AT 17/00Z NEAR THE COAST AND BEGINNING AT 06Z FURTHER NORTH AT IAH.
TOMORROW NIGHT THROUGH FRIDAY MORNING IS LOOKING INCREASINGLY WET
WITH LOW CEILINGS AND FOG.  42 

PREV DISCUSSION... /ISSUED 947 PM CST WED FEB 15 2012/ 

UPDATE...
THE DRYLINE HAS REMAINS JUST TO THE WEST OF OUR CWA AND HAS BEEN
SLOW TO ADVANCE EASTWARD THIS EVENING. THE COMBINATION OF DAMP
GROUND AND LIGHT WINDS HAS LED TO WIDESPREAD FOG DEVELOPMENT
ACROSS THE REGION WITH SEVERAL LOCATIONS REPORTING DENSE FOG WITH
VISIBILITIES OF 1/4 MILE OR LESS. HAVE ISSUED A DENSE FOG ADVISORY
FOR ALL OF SOUTHEAST TEXAS THROUGH MIDNIGHT. VISIBILITIES SHOULD
BEGIN TO IMPROVE AS THE DRIER AIR SLOWLY WORKS IN FROM THE WEST
OVERNIGHT AND WHEN THE FRONT ITSELF FINALLY PUSHES THROUGH JUST
BEFORE SUNRISE. ONLY OTHER CHANGE THIS EVENING WAS TO RAISE MIN
TEMPS OVERNIGHT...PARTICULARLY ACROSS OUR SOUTHEASTERN COUNTIES. 38
