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

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.
