SHORT TERM  
 
(TODAY THROUGH WEDNESDAY NIGHT)  
ISSUED AT 340 AM CST TUE NOV 19 2024  
 
COOLER/DRIER AIR WILL CONTINUE TO FILTER DOWN INTO THE AREA TODAY IN  
THE WAKE OF YESTERDAY' S COLD FRONT. A SECOND REINFORCING FRONT WILL  
BE MOVING THROUGH TOMORROW. SURFACE HIGH PRESSURE BUILDING DOWN INTO  
THE STATE ALONG WITH AN ALMOST ZONAL FLOW ALOFT SHOULD HELP TO MAIN-  
TAIN THE COOL/QUIET/DRY AIR MASS OVER SE TX THROUGH THE SHORT TERM.  
 
AS FOR TEMPERATURES, HIGHS TODAY WILL BE IN THE MID AND UPPER 70S AS  
MOSTLY SUNNY SKIES PREVAIL. LOWS TONIGHT SHOULD RANGE FROM THE UPPER  
40S ACROSS THE NORTHERN MOST COUNTIES (PINEY WOODS) TO THE LOWER AND  
MID 50S FOR MUCH OF THE REST OF THE CWA...AROUND 60 AT THE IMMEDIATE  
COAST. THE SECONDARY SURGE OF EVEN COOLER/DRIER AIR WILL LOWER HIGHS  
TOMORROW TO THE UPPER 60S TO LOWER 70...WITH LOWS FROM THE UPPER 30S  
NORTH TO THE LOWER TO MID 40S CENTRAL/SOUTH (MID 50S AT THE BEACHES).

LONG TERM  
 
(THURSDAY THROUGH MONDAY)  
ISSUED AT 340 AM CST TUE NOV 19 2024  
 
HIGH PRESSURE WILL BUILD ACROSS SOUTHEAST TX THURSDAY, RESULTING  
IN BENIGN CONDITIONS, LIGHT WINDS, AND SUNNY SKIES. THE HIGHS ON  
THURSDAY WILL BE GENERALLY IN THE UPPER 60S TO LOW 70S AREAWIDE  
AND WILL FEEL PRETTY DRY AS DEWPOINTS FALL INTO THE UPPER 20S TO  
MID 30S OVER THE INLAND PORTIONS. THE LOW TEMPERATURES THURSDAY  
NIGHT WILL WARM UP A LITTLE AND RANGE BETWEEN THE LOW TO MID 40S  
OVER AREAS NORTH OF I-10 (UPPER 30S IN THE PINEY WOODS), THE MID  
TO UPPER 40S ALONG AND SOUTH OF I-10, AND THE LOW TO MID 50S ALONG  
THE COAST. A SIMILAR WEATHER PATTERN IS TO BE EXPECTED ON FRIDAY.  
 
FOR THE UPCOMING WEEKEND, THE HIGH PRESSURE WILL SHIFT TO OUR EAST  
NORTHEAST, ALLOWING FOR THE RETURN OF SOUTHERLY FLOW. CONSEQUENTLY,  
WE WILL SEE A GRADUAL RISE IN TEMPERATURES THROUGH EARLY NEXT WEEK  
AND THE HIGHS MAY INCREASE BACK INTO THE UPPER 70S TO MID 80S BY  
MONDAY. LOW LEVEL MOISTURE AND INSTABILITY MAY REMAIN LOW ENOUGH TO  
KEEP US RAIN FREE DURING THE WEEKEND. AS MOISTURE INCREASES EARLY  
NEXT WEEK, HOWEVER, WE MAY SEE A SLIGHT UPTICK IN RAIN CHANCES.

AVIATION  
 
(06Z TAF ISSUANCE)  
ISSUED AT 1127 PM CST MON NOV 18 2024  
 
RAIN IS NOW OVER THE COASTAL WATERS AND CLOUDS ARE SCATTERING OUT,  
LEAVING NEARLY CALM WINDS AND VFR ACROSS THE AREA...EXCEPT AROUND  
CLL, WHERE 1/2 TO 1 1/4SM FOG HAS CROPPED UP. INITIAL HOURS AT CLL  
HANDLE THIS BEFORE ENOUGH DRY AIR WORKS IN TO RETURN TO VFR.  
MEANWHILE, SHOULD EXPECT SOME PATCHY FOG FARTHER SOUTH IN THE  
PRE-DAWN HOURS, DISSIPATING SHORTLY AFTER SUNRISE.  
 
BEYOND THAT, SKC WITH LIGHT NW WINDS. THE EXTENDED AT IAH DOES  
BEGIN TO ACCOUNT FOR STRENGTHENING WINDS ASSOCIATED WITH  
REINFORCING FRONT, AND NORTHERN TERMINALS WILL LIKELY NEED TO JOIN  
IN BY THE 12Z CYCLE.  
 
 
   
MARINE  
 
ISSUED AT 340 AM CST TUE NOV 19 2024  
 
WINDS AND SEAS WILL CONTINUE TO SUBSIDE TODAY, HOWEVER, A DRY  
REINFORCING FRONT PUSHING OFF THE COAST SOMETIME LATE TONIGHT INTO  
EARLY WEDNESDAY WILL USHER IN STRONG OFFSHORE WINDS (20-25 KT) AND  
ELEVATED SEAS (6-9 FT) IN ITS WAKE. CAUTION FLAGS AND SMALL CRAFT  
ADVISORIES WILL LIKELY BE NEEDED FROM EARLY WEDNESDAY TO EARLY  
THURSDAY. WINDS AND SEAS WILL GRADUALLY SUBSIDE THURSDAY NIGHT INTO  
FRIDAY AS HIGH PRESSURE BUILDS ACROSS THE REGION. ONSHORE FLOW IS  
EXPECTED TO RETURN THIS WEEKEND AND MAY INCREASE LATE SATURDAY INTO  
EARLY NEXT WEEK AS THE LOCAL PRESSURE GRADIENT TIGHTENS.
