AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
300 AM CDT TUE JUL 3 2007

.DISCUSSION...THE FIRST FORECAST DECISION FOR THE SHIFT IS THE
STATUS OF THE FLASH FLOOD WATCH. THE VARIOUS MODELS SUGGEST THAT
WEDNESDAY MAY BE BE MORE SIGNIFICANT FOR RAINFALL OVER THE MID AND
UPPER VALLEY THAN TODAY. NONETHELESS...MOISTURE LEVELS REMAIN HIGH
TODAY...WITH ABOVE AVERAGE AMOUNTS EXTENDING WELL INLAND...EVEN AS
FAR AS DEL RIO AND BEYOND...BUT DEFINITELY WELL ABOVE AVERAGE FOR
DEEP SOUTH TEXAS. THE MID LEVEL LOW REMAINS OVER CENTRAL TEXAS...BUT
IS FORECAST TO DRIFT SLOWLY SOUTH AND SOUTHWEST THROUGH THURSDAY. H5
RIDGING IS BLOCKING WESTWARD MOVEMENT OF THE LOW IN THE SHORT
TERM...AND IT WONT BE UNTIL AFTER WEDNESDAY THAT THE LOW CAN MAKE
SIGNIFICANT PROGRESS IN THAT DIRECTION. DUE TO SIGNIFICANT PREVIOUS
RAINFALL IN THE UPPER VALLEY AND THE POTENTIAL FOR REDEVELOPMENT
TODAY...WILL REISSUE THE FLASH FLOOD WATCH FOR ZAPATA...STARR...AND
JIM HOGG COUNTIES. THE MID AND LOWER VALLEY HAS THUS FAR BEEN SPARED
FROM SIGNIFICANT HEAVY RAINFALL...BUT MAY NEED TO EXTEND THE WATCH
FARTHER EAST EITHER TODAY OR FOR WEDNESDAY WHEN MORE WIDESPREAD RAIN
IS EXPECTED ACROSS DEEP SOUTH TEXAS.

THUNDERSTORM REDEVELOPMENT SOUTH OF RIO GRANDE CITY AT AROUND 2:30
AM MOVING NORTH...PLUS A BAND OF RAIN APPROACHING FROM THE GULF.
LOOKS LIKE ANOTHER ROUND FOR TODAY.

THE MAIN FORECAST EMPHASIS IS ON THE SHORT TERM...WITH LOWER
TEMPERATURES THAN GUIDANCE INDICATED BECAUSE OF CLOUD COVER AND
RAIN. CONDITIONS ARE EXPECTED TO IMPROVE AFTER THURSDAY...THOUGH
SHOWERS MAY CONTINUE TO MOVE UP FROM THE SOUTH TO AFFECT THE COASTAL
REGIONS. MID LEVEL RIDGING AND SURFACE HIGH PRESSURE WILL OTHERWISE
RESULT IN FAIRLY SEASONAL WEATHER FOR THE LATTER PART OF THE
FORECAST.
&&

.PREV DISCUSSION...ISSUED AT 717 PM CDT MON JUL 2 2007...
THUNDERSTORMS THIS EVENING RESTRICTED TO EXTREME NORTHWEST ZAPATA
COUNTY AND FURTHER INTO MEXICO. STORMS ARE FORMING ON OUTFLOW
BOUNDARY SWEEPING WEST INTO MEXICO...WITH NO OTHER BOUNDARIES NOTED
IN OR AROUND THE CWA. THE NIGHT SHIFT WILL MAKE THE DECISION ON
EXTENDING THE FLOOD WATCH. WITH ABUNDANT MOISTURE STILL AVAILABLE...
ONE ROGUE OUTFLOW COULD START THE RAIN PROCESS ALL OVER...SO WILL
KEEP POPS IN FOR THE EVENING. WILL NOT NEED UPDATE.
&&

.MARINE...AT 1 AM BUOY 20 REPORTED SOUTHEAST WINDS AT 12 KNOTS WITH
GUSTS TO 14 KNOTS AND SEAS AT 4 FEET WITH A 6 SECOND PERIOD. A HIGH
PRESSURE RIDGE EXTENDING INTO THE COASTAL WATERS WILL MAINTAIN LIGHT
TO MODERATE SOUTHEASTERLY WINDS OVER THE MARINE AREAS THIS WEEK.
WINDS AND SEAS WILL INCREASE SLIGHTLY ON THURSDAY...AND WILL THEN
DECREASE WITH THE WINDS BECOMING LIGHT AND THE SEAS BECOMING LOW BY
SATURDAY. A MID LEVEL LOW PRESSURE SYSTEM LOCATED ACROSS CENTRAL
TEXAS WILL CONTINUE TO MAINTAIN A CHANCE FOR SHOWERS AND ISOLATED
THUNDERSTORMS MOVING ACROSS PORTIONS OF THE MARINE AREAS AT TIMES
FOR THE NEXT FEW DAYS. WINDS AND SEAS MAY INCREASE IN AND NEAR ANY
SHOWERS OR THUNDERSTORMS.
&&

.AVIATION...VFR TO MVFR CONDITIONS WITH CLEAR TO PARTLY CLOUDY SKIES
AND LIGHT SOUTHEAST WINDS ARE OCCURRING AT THE REGIONAL AIRPORTS.
THE LOWERED CONDITIONS ARE DUE TO REDUCED CEILINGS. THERE IS A
CONTINUED CHANCE FOR SHOWERS AND ISOLATED THUNDERSTORMS MOVING
ACROSS PORTIONS OF THE CWA TODAY. ANY SHOWERS OR THUNDERSTORMS MAY
REDUCE CEILINGS OR VISIBILITIES TO MVFR OR TEMPORARY IFR CONDITIONS.
LIGHT WINDS EARLY THIS MORNING WILL BECOME MODERATE BY THIS
AFTERNOON. THE WINDS MAY INCREASE IN AND NEAR ANY SHOWERS OR
THUNDERSTORMS. VFR TO TEMPORARY IFR CONDITIONS WILL PREVAIL OVER THE
REGIONAL AERODROMES DURING THE NEXT 24 HOURS.
