..NEW AVIATION
SHORT TERM
(TODAY THROUGH THURSDAY NIGHT)
ISSUED AT 239 AM CST WED NOV 20 2024
NO ISSUES FOR THE SHORT-TERM. THE PASSAGE OF A SECONDARY COLD FRONT
OVERNIGHT WILL BRING MODERATE/STRONG CAA ACROSS THE REGION TODAY. A
BREEZY N/NW FLOW ALONG WITH CLEAR SKIES SHOULD LEAD TO HIGHS IN THE
MID TO UPPER 60S TODAY. WINDS ARE EXPECTED TO DECREASE TONIGHT WITH
LOWS RANGING FROM THE MID AND UPPER 30S FOR MOST LOCATIONS OVER THE
CWA...LOWER TO MID 40S IN/AROUND THE HOUSTON METRO AND AT THE IMME-
DIATE COAST.
AS SURFACE HIGH PRESSURE SETTLES ACROSS THE REGION ON THURS AND THE
PRESSURE GRADIENT WEAKENS, THE OFFSHORE WINDS WILL BE DECREASING IN
RESPONSE. LOOK FOR ANOTHER COOL/DRY/QUIET DAY TOMORROW WITH HIGHS A
DEGREE OR TWO WARMER THAN TODAY...FROM THE UPPER 60S TO AROUND 70.
LOWS TOMORROW NIGHT SHOULD BE SIMILAR TO THAT OF TONIGHT...WITH THE
SLIGHTLY WARMER READINGS IN/AROUND URBAN AREAS. OVERNIGHT LOWS WILL
RANGE FROM THE UPPER 30S TO LOWER 40S FOR MOST LOCATIONS...FROM THE
MID TO UPPER 40S FOR H-TOWN PROPER AND THE COAST. 41
LONG TERM
(FRIDAY THROUGH TUESDAY)
ISSUED AT 239 AM CST WED NOV 20 2024
THERE IS THE HINT OF A VERY WEAK COLD FRONT PASSING THROUGH AND
STALLING NEAR THE I-45 CORRIDOR FRIDAY MORNING, BUT WILL NOT DO MUCH
FOR US EXCEPT MAYBE A MORE DEFINED TEMPERATURE GRADIENT BETWEEN THE
AREAS EAST AND WEST OF I-45 ALONG WITH MAINTAINING NORTHERLY FLOW
OVER SOUTHEAST TX. WE COULD SEE HIGH TEMPERATURES IN THE MID 60S TO
LOWER 70S OVER AREAS ALONG AND EAST OF I-45 AND THE LOW TO MID 70S
FOR AREAS WEST OF I -45. ANOTHER AREA OF HIGH PRESSURE MAY BUILD
OVER TEXAS ON FRIDAY. THE LOWS ON FRIDAY WILL BE IN THE UPPER 30S TO
LOW 40S OVER THE BRAZOS VALLEY AND PINEY WOODS REGION, IN THE MID TO
UPPER 40S OVER THE REST OF THE INLAND PORTIONS, AND IN THE MID 50S
TO LOW 60S ALONG THE COASTS.
SOUTHERLY FLOW IS EXPECTED TO RETURN THIS WEEKEND AS THE HIGH
PRESSURE MOVES AWAY AND WE WILL LIKELY SEE A GRADUAL RISE IN
TEMPERATURES THROUGH EARLY NEXT WEEK. IN FACT, THE HIGH TEMPERATURES
MAY BOUNCE BACK INTO THE LOW TO MID 80S BY MONDAY. MODELS ARE
HINTING AT A POSSIBLE COLD FRONT SOMETIME MID-WEEK AS A WEAK UPPER
LEVEL TROUGH MOVES ACROSS THE SOUTHERN PLAINS. WE WILL NEED TO WAIT
A LITTLE MORE AND SEE IF THE FRONT WILL ACTUALLY HAVE ENOUGH SUPPORT
FOR IT TO PASS THROUGH SOUTHEAST TEXAS, GIVEN THE CURRENT MID/UPPER
LEVEL SET UP. IF IT DOES, WE MAY GET BETTER RAIN CHANCES AHEAD OF
AND ALONG THE FRONT AS WELL AS A SLIGHT DECREASE IN TEMPERATURES
DURING THE MID WEEK PERIOD.
