AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
530 AM CDT THU APR 3 2008

...UPDATED EXTENDED DISCUSSION...

.DISCUSSION...LIGHT TO MODERATE SOUTHEAST WINDS PREVAIL EARLY THIS
MORNING AS HIGH PRESSURE WASHES GENTLY WEST OVER THE NORTHERN GULF
OF MEXICO. LOW CLOUDS ARE BOTH DEVELOPING FROM PREEXISTING MOISTURE
AND ARE ALSO MOVING INLAND FROM THE GULF ON THE FLOW. IFR CEILINGS
HAVE MATERIALIZED ALONG COASTAL AREAS. LIGHT TO MODERATE FOG WILL
COULD DEVELOP OVER THE NEXT FEW HOURS...IF WINDS DECOUPLE.

MORNING WILL BRING INCREASING WINDS AS PRESSURE FALLS DEVELOP TO THE
NORTH OVER THE TEXAS PANHANDLE...THIS BEING PART OF A STORM SYSTEM
TAKING SHAPE OVER THE HIGH PLAINS. THE LOW PRESSURE CENTER WILL SAG
SOUTH DURING THE DAY...TO WEST TEXAS...MAINTAINING BREEZY SOUTHEAST
WINDS FOR DEEP SOUTH TEXAS. LOW CLOUDS SHOULD MIX OUT EARLY THIS
MORNING...GIVING WAY TO MOSTLY SUNNY SKIES AND WARMER THAN AVERAGE
TEMPERATURES.

A POSITIVE TILT AND PROGRESSIVE H5 SHORT WAVE TROUGH WILL BE MOVING
EAST ACROSS THE SOUTHWEST STATES TODAY...ATTEMPTING TO KEEP PACE AND
IN PHASE WITH A NORTHERN BRANCH TROUGH MOVING ACROSS THE NORTHERN
STATES. EMBEDDED UNDER THE RIDGE UPSTREAM OF THE TROUGH COMPLEX IS A
MARITIME POLAR HIGH PRESSURE AIR MASS THAT WILL PROVIDE THE NEXT
COLD FRONT FOR DEEP SOUTH TEXAS THIS FRIDAY. THE FRONT WILL MOVE
SOUTH INTO CENTRAL TEXAS TONIGHT...INTERACTING WITH THE DRY LINE TO
SPARK CONVECTION. MOST OF THE MID LEVEL ENERGY ASSOCIATED WITH THE
TROUGH WILL CONCENTRATE ACROSS CENTRAL AND EAST TEXAS...AS THE
TROUGH ITSELF WILL BE TOO SHALLOW TO INFLUENCE WEATHER AS FAR SOUTH
AS DEEP SOUTH TEXAS. PRECIP CHANCES WILL EXTEND AS FAR SOUTH AS THE
MIDDLE TEXAS COAST BY LATE FRIDAY. A WIND SHIFT IS EXPECTED ACROSS
DEEP SOUTH TEXAS BY MID FRIDAY...AND SOME INTERACTION WITH THE SEA
BREEZE IS POSSIBLE...SO WILL KEEP SLIGHT CHANCE POPS IN THE FORECAST.

ONCE THE COLD FRONT HAS MOVED THROUGH FRIDAY AFTERNOON...DRIER
CONDITIONS WILL DEVELOP WITH MOSTLY CLEAR TO CLEAR SKIES FRIDAY
NIGHT...LEADING TO A SEASONAL AND SUNNY SATURDAY. WINDS WILL QUICKLY
SHIFT BACK TO ONSHORE BY SUNDAY...WITH SKIES BECOMING PARTLY CLOUDY.

ANOTHER STORM SYSTEM WILL SPIN UP IN THE PLAINS BY THE MIDDLE OF
NEXT WEEK...EVENTUALLY DRIVING ANOTHER COLD FRONT INTO IF NOT
THROUGH DEEP SOUTH TEXAS LATE IN THE WEEK. RAIN CHANCES WILL REMAIN
SLIM THROUGH THE FORECAST HOWEVER...WITH NOT MUCH HELP FROM THE TAIL
ENDS OF FRONTS THAT JUST BRUSH BY US.
