146 PM CDT MON SEP 26 2011

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...DEEP STORM VORTEX
OVER NORTHERN ILLINOIS IS NOT A BIG PLAYER FOR DEEP SOUTH TEXAS AT
THE MOMENT. RATHER...HIGH PRESSURE OVER THE WEST GULF IS
INTERACTING WITH LOW PRESSURE TROUGHING IN WEST TEXAS EXTENDING
NORTH INTO THE SOUTHERN HIGH PLAINS. THE RESULT IS MODERATE AND
GUSTY SOUTHEAST TO SOUTH WINDS AND SUNNY SKIES THIS
AFTERNOON...WITH TEMPS CURRENTLY IN THE LOW TO MID 90S NEAR THE
COAST TO NEAR 100 INLAND NEAR LAREDO. COULD SEE A FEW RECORD HIGH
TEMPS APPROACHED THROUGH THE REST OF THE AFTERNOON AS WINDS
CONTINUE OUT OF THE SOUTH. BY THIS EVENING... WINDS WILL DECREASE
AND SHIFT A BIT TO SOUTHEAST...BRINGING A MILD NIGHT WITH LOW
TEMPS IN THE MID TO UPPER 70S AND A FEW LOW CLOUDS DRIFTING IN
FROM THE GULF AFTER MIDNIGHT. TUESDAY WILL BE JUST A BIT
COOLER...BUT STILL SEVERAL DEGREES WARMER THAN NORMAL. A FEW MORE
AFTERNOON CU WILL DEVELOP ON MODERATE SOUTH SOUTHEAST WINDS.
LITTLE CHANGE TUESDAY NIGHT AS LOW TEMPS REMAIN WELL IN THE 70S
WITH A FEW LOW CLOUDS NEAR THE COAST AFTER MIDNIGHT.

.LONG TERM...LONG TERM FEATURES DOMINATED BY HIGHLY AMPLIFIED FLOW
PATTERN BUILDING ACROSS THE CENTER OF THE US...WITH SOUTH TEXAS
CAUGHT UNDER A SMALL LOBE OF THE SLOWLY DEPARTING BOWLING BALL
UPPER LOW ACROSS THE EASTERN US. THIS WILL PROVIDE SOME
INSTABILITY TO THE REGION...WHICH WILL COMBINE WITH AMPLE LLVL
GULF MOISTURE TO HELP THE SEABREEZE SPARK SOME
SHOWERS...ESPECIALLY WEDNESDAY THROUGH FRIDAY. BY FRIDAY...THE
UPPER FLOW SHIFTS FROM WESTERLY TO NORTHERLY...REINTRODUCING THE
DRIER AIR SEEN A FEW DAYS LAST WEEK. THIS WILL LIKELY ARRIVE IN
THE FORM OF A BACK DOOR COLD FRONT FRIDAY EVENING. THE FURTHER
EAST THE NORTH-SOUTH UPPER CORRIDOR DEVELOPS...THE LESS LIKELY THE
FRONT WILL ARRIVE AND BETTER CHANCES FOR RAIN FRIDAY INTO EARLY
SATURDAY. EVEN IF THE FRONT DOESN'T MOVE THROUGH FULLY...THE DRIER
AIR IS LIKELY TO MOVE INTO THE REGION FOR THE WEEKEND...ESPECIALLY
IN THE WESTERN VALLEY AWAY FROM ANY LLVL MARINE INFLUENCES. WILL
HOLD ON TO POPS WED-FRI AND NOT MENTION SATURDAY AND BEYOND.
TEMPERATURES WILL REMAIN ABOVE NORMAL...BUT WILL TEMPER JUST A BIT
AS THICKNESSES DECREASE WITH THE APPROACH OF THE MIDLEVEL
WEAKNESS. STILL EXPECTING 90 PLUS DEGREES FOR THE BEGINNING OF
OCTOBER.

&&

.MARINE...TONIGHT THROUGH TUESDAY NIGHT...BUOY 42020 REPORTS
MODERATE SOUTH WINDS AND SEAS BETWEEN FIVE AND SIX FEET THIS
AFTERNOON. EXERCISE CAUTION CONDITIONS WILL CONTINUE THROUGH THIS
EVENING FOR THE LOWER TEXAS COAST AS HIGH PRESSURE OVER THE GULF
INTERACTS WITH LOWER PRESSURE INLAND. THE LOCAL PRESSURE GRADIENT
WILL LOOSEN UP ON TUESDAY AS HIGH PRESSURE IN THE SOUTHERN PLAINS
SINKS SOUTH AND FILLS INTO TEXAS. UNSETTLED TROPICAL CONDITIONS IN
THE BAY OF CAMPECHE MAY ALLOW ISOLATED SHOWERS TO DRIFT NORTH
ALONG THE NORTHEAST COAST OF MEXICO...BUT DID NOT INCLUDE MENTION
IN THIS FORECAST DUE TO MIXED SIGNAL IN MODELS. THE NAM DOES NOT
SHOW THE SAME SHOWERS AS THE GFS...REMAINING DRIER OVER ALL.

WEDNESDAY THROUGH FRIDAY...CONDITIONS WILL BE A BIT BREEZY LATER
IN THE EXTENDED PERIOD AS A FRONT APPROACHES FROM THE NORTH. DO
NOT YET EXPECT ADVISORY CRITERIA TO BE REACHED...BUT WIDESPREAD
AREAS OF 15 TO 20 KNOT ARE POSSIBLE...ESPECIALLY FRIDAY. SEAS WILL
REMAIN MODEST AT 3 FEET OR LESS...WITH 1 TO 2 FEET COMMON WED AND
THU. A FRONT WILL ATTEMPT TO MOVE IN FROM THE NORTHEAST LATE
FRIDAY. WINDS ARE EXPECTED TO SHIFT MORE TO THE NORTHEAST BUT
STRENGTH IS STILL IN DOUBT AT THIS JUNCTURE. NE FETCH ACROSS
SHALLOW CONTINENTAL SHELF OF THE GULF WILL PICK SEAS UP TO AT
LEAST 4 FEET FOR THE GULF WATERS DURING AND AFTER THE WIND SHIFT.
