AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX

.DISCUSSION...
06Z TAF DISCUSSION IN AVIATION SECTION.

&&

.AVIATION...
HIGH CLOUDS CONTINUE TO MOVE INTO SE TX TONIGHT SO THAT ALONG
WITH WINDS AROUND 5KTS...DO NOT THINK THERE WILL BE MUCH IN THE
WAY OF FOG. DID LEAVE SOME MVFR CIGS FOR KCXO/KLBX AS THESE
TERMINALS HAVE THE HIGHEST CHANCE OF FOG FORMING DESPITE CLOUDS
AND WINDS DUE TO CLOSE T/TD SPREAD. WINDS SHOULD PICK UP TOMORROW
FROM THE SE WITH GENERALLY VFR CIGS.

UPDATE...
UPDATED TEMPERATURE AND HUMIDITY GRIDS.

DISCUSSION...
THE SURFACE HIGH PRESSURE RIDGE CONTINUED TO EXTEND INTO SE TX
THIS EVENING. ALTHOUGH LIGHT ONSHORE FLOW HAS BEGUN...DEWPOINTS
WERE BEING SLOW TO RISE. THE LATEST NAM12 FORECASTS THE RIDGE TO
STAY IN PLACE OVERHEAD TONIGHT AND FOR THE SURFACE MOISTURE TO
ONLY BEGIN SIGNIFICANTLY RISING ON TUESDAY. WITH THAT IN MIND...
TWEAKED THE OVERNIGHT LOW TEMPERATURES AND RESULTING HUMIDITY
FORECASTS FOR TONIGHT AND TUESDAY MORNING.

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

AVIATION...
OVERNIGHT EXPECT THERE TO BE A BIT MORE LOW LEVEL MOISTURE BUT
NOT ENOUGH FOR EVEN WIDESPREAD FOG FOR MVFR CIGS. MAY SEE IT AT
KCXO/KLBX/KSGR. HOUSTON AND OTHER TERMINALS MAY GET 5SM/6SM AND
MAY NEED TO REVISIT KCLL FOR 5SM AT 06Z UPDATE. WINDS SHOULD
DECOUPLE BUT CLOSING T/TD SPREADS MAY BE TOUGH TO ACHIEVE UNTIL
MORNING HOURS. HIGH CLOUDS ADVANCING FROM SW MAY HAVE SOMETHING TO
SAY ABOUT FOG. WINDS SHOULD INCREASE FROM SE TOMORROW WITH SOME
LOW CU AND HIGH CLOUDS FOR VFR CIGS.
