RADAR IS QUIET WITH THE LOSS OF HEATING. EXPECT SCT SHWRS AND ISO

DISCUSSION...
00Z TAF DISCUSSION IN AVIATION SECTION.

AVIATION...
CONVECTION CONTINUES TO DWINDLE THIS EVENING WITH THE LOSS OF DAY
TIME HEATING. WATER VAPOR IMAGERY SHOWS UPPER LOW SOUTH OF THE RIO
GRANDE WHICH SHOULD MOVE INTO MEXICO TONIGHT INTO TOMORROW. UPPER
LEVEL RIDGE LOOKS TO BE BUILDING OVER THE AREA AND MAY BE MORE OF
AN INFLUENCE TOMORROW. THERE WILL STILL BE SOME HIGHER MOISTURE IN
THE AREA TO SUPPORT SHOWER ACTIVITY SO WILL KEEP MENTION OF VCSH
FOR TERMINALS ALONG THE COAST AND HOUSTON AREA. THINK COVERAGE
WILL BE LESS THAN TODAY ESPECIALLY IF THE RIDGE BUILDS.

OTHER CONCERN WILL BE POSSIBILITY OF FOG. NOT SURE HOW MUCH
BOUNDARY LAYER WILL REALLY DECOUPLE AND HOW DEEP OF AN INVERSION
WILL BE ESTABLISHED. WILL MENTION MVFR TYPE VSBY FOR MOST AREAS
BUT WILL WATCH OBS CLOSELY. TAFS MAY NEED TO BE UPDATED AT 06Z
FOR STRONGER MENTION OF LOWER VSBY.
