.DISCUSSION...
FOR THE 15/00Z TAF ISSUANCE.

&&

.AVIATION...
ONLY CONCERN IN THE SHORT TERM IS THE POSSIBILITY OF SOME PATCHY
FOG TOWARD SUNRISE. GRADIENT WILL BE A LITTLE STRONGER OVER
SOUTHEAST TEXAS TONIGHT...THEREFORE...NOT EXPECTING MUCH IN THE
WAY OF FOG FOR KBPT. WINDS ARE EXPECTED TO DIMINISH OVER SOUTHWEST
AND SOUTH CENTRAL LOUISIANA...THAT MAY LEAD TO SOME PATCHY FOG
WITH MVFR TYPE VISIBILITY AT KLCH/KLFT/KARA AND WILL PLACE A TEMPO
GROUP TO COVER THAT BETWEEN 15/09Z-13Z.

.PREV DISCUSSION... /ISSUED 403 PM CDT TUE MAY 14 2013/

DISCUSSION...
THE SURFACE HIGH PRESSURE CONTINUED MOVING TO THE EAST TODAY
ALLOWING FOR LIGHT TO MODERATE SOUTH TO SOUTHEAST SURFACE WINDS. VIS/IR
SATELLITE INDICATE LIGHT CLOUDS MOVING ACROSS THE SKIES BUT
FOR MOST PART...TODAY WAS A NICE SUNNY DAY. THE LACK OF AVAILABLE
MOISTURE FROM THE PAST TWO DAYS ALLOWED FOR CONSIDERABLE DRYING
AND MIN RH`S DROPPED TO AROUND 30 PERCENT WITH A FEW SITES JUST
BELOW THAT. OVERNIGHT EXPECT THE LIGHT TO MODERATE SOUTH TO
SOUTHWEST WINDS TO CONTINUE TO ADVECT IN MORE GULF MOISTURE INTO
THE LOW LEVELS WHICH SHOULD WARM THE AREA OVERNIGHT BY A FEW
DEGREES MORE THAN LAST NIGHT.

BEST CHANCES FOR SHOWERS WILL BE SOME ISOLATED SHOWERS TOMORROW
AFTERNOON OR EVENING. HIRES GUIDANCE INDICATED AN MCS WILL DEVELOP
AND MOVE OVER CENTRAL TEXAS BUT SHOULD PASS TO THE NORTH OF THE
AREA. SOME STREAMER SHOWERS AND OR ISOLATED THUNDERSTORMS CAN NOT
BE RULED OUT. CARRIED 30 POP FOR THE NORTHERN PART OF THE CWA IN
CASE THE MCS MOVES FURTHER SOUTH THAN FORECASTED.

REST OF THE FORECAST LOOKS WARM AND DRY. POSSIBLE CHANCE FOR SOME
SHOWERS TUESDAY INTO WEDNESDAY NEXT WEEK AS A LOW PRESSURE SYSTEM
WILL PASS THROUGH THE AREA BUT WITH LITTLE MODEL AGREEMENT...
CHOSE TO WAIT FOR BETTER AGREEMENT BEFORE INTRODUCING MUCH POP.
COULD BREAK INTO THE 90`S THIS WEEKEND TOWARDS THE NORTHER AREAS
OTHERWISE MAX TEMPS WILL BE IN THE UPPER 80S WITH LOWS IN THE MID
TO UPPER 60S.

MARINE...
HIGH PRESSURE OVER THE LOWER MISSISSIPPI VALLEY WILL CONTINUE
PUSHING EASTWARD...WHICH WILL ALLOW WEAK TO MODERATE ONSHORE FLOW
TO LINGER THROUGH THE REMAINDER OF THE WEEK INJECTING MOISTURE INTO
THE LOW LEVELS. THERE WILL A WEAK CHANCE FOR SOME SHOWERS TO
DEVELOP TOMORROW EVENING BUT SHOULD REMAIN ISOLATED. WAVES WILL BE
1 TO 2 IN THE INNER COASTAL WATERS AND 2 TO 3 OFFSHORE.
