AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
354 AM CDT WED AUG 7 2013

.SHORT TERM /TODAY THROUGH THURSDAY/...TODAY APPEARS TO BE A
REPEAT OF YESTERDAY WITH VERY HOT AND BREEZY TO WINDY CONDITIONS
EXPECTED ACROSS THE RIO GRANDE VALLEY AS THE 500MB RIDGE ACROSS
TEXAS AND NORTHERN MEXICO CONTINUES TO PROVIDE STRONG SUBSIDENCE
ACROSS THE AREA. WITH DEWPOINTS IN THE 60S ACROSS THE CWA
TODAY...HEAT INDEX VALUES WILL EASILY REACH 105 TO 110 DEGREES
THIS AFTERNOON WITH ISOLATED AREAS REACHING 111 DEGREES. WILL
ISSUE SPS TO ADDRESS THE HEAT INDEX TEMPS FOR TODAY AND THURSDAY.
THE OTHER CONCERN IS THE WINDS ALONG THE COASTAL SECTIONS THIS
AFTERNOON. WITH WINDS GUSTING TO NEAR 25 MPH ALONG THE
COAST...BLOWING SAND AND DUST WILL REDUCE VISIBILITIES ACROSS THE
COASTAL SECTIONS OF CAMERON COUNTY TODAY. WILL ISSUE NPW FOR
BLOWING DUST/SAND ACROSS THE LOWER TEXAS COAST.

WINDS SHOULD DIMINISH ACROSS THE RIO GRANDE VALLEY TONIGHT AS THE
PRESSURE GRADIENT BEGINS TO DIMINISH ACROSS THE LOWER TEXAS COAST.
THE VERY HOT TEMPERATURES WILL PERSIST THURSDAY EVEN AS THE UPPER
LEVEL RIDGE ACROSS THE AREA BECOMES ELONGATED ACROSS THE NORTHWEST
GULF COAST STATES. BELIEVE WINDS SHOULD NOT BE AS STRONG THURSDAY AS
TODAY SO THE BLOWING DUST/SAND SHOULD ALSO DIMINISH. HAZY CONDITIONS
WILL PERSIST TODAY THROUGH THURSDAY AS THE AFRICAN DUST ACROSS THE
NORTHWEST CARIBBEAN SEA EXTENDING INTO THE WESTERN GULF OF MEXICO
CONTINUES TO MOVE ACROSS THE CWA.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...THE MIGHTY H5 RIDGE
WILL START TO FLATTEN BEGINNING ON FRIDAY...SQUEEZED BETWEEN A
TROUGH TO THE NORTH AND THE TUTT MOVING INTO THE GULF. MODELS SHOW
A SHARP RISE IN MOISTURE BEGINNING LATE FRIDAY...RISING ABOVE 2
INCHES BY DAWN SATURDAY. MOISTURE INCREASES AND INSTABILITY ALOFT
WILL BRING OUR FIRST REAL CHANCE OF RAIN IN NEARLY A MONTH. HAVE
INCREASED POPS FURTHER INTO THE CHANCE CATEGORY FOR SATURDAY AND
SUNDAY...AND STARTING TO LOOK MORE LIKELY FOR ANOTHER ROUND ON
MONDAY WITH THE SEABREEZE. THE RIDGE BUILDS BACK INTO PLACE
BRIEFLY ON TUESDAY BEFORE THE NEXT INVERTED TROUGH SWEEPS
WESTWARD ACROSS THE GULF.

&&

.MARINE...
TODAY THROUGH THURSDAY...SEAS WERE NEAR 5 FEET WITH SOUTH WINDS NEAR
17 KNOTS AT BUOY020 EARLY THIS MORNING. MODERATE TO STRONG SOUTH
WINDS WILL PREVAIL ACROSS THE COASTAL WATERS TODAY INTO TONIGHT
BEFORE THE PRESSURE GRADIENT WEAKENS ACROSS THE WESTERN GULF OF
MEXICO THURSDAY. WILL GO AHEAD AND ISSUE SMALL CRAFT ADVISORY FOR
THE LAGUNA MADRE AND THE NEAR SHORE WATERS OF THE LOWER TEXAS COAST
TODAY AND WORD SCEC FOR THE FAR OFFSHORE WATERS.

FRIDAY THROUGH SUNDAY...WINDS RELAX AS THE LOW IN CENTRAL TEXAS
WEAKENS. ONSHORE FLOW AROUND 10 KNOTS WILL CONTINUE THROUGH THE
WEEKEND...ALLOWING SEAS TO LOWER TO 2 TO 4 FEET.

&&

.FIRE WEATHER...LOW RELATIVE HUMIDITY ACROSS THE WESTERN HALF OF THE
CWA IN COMBINATION WITH 20FT WINDS OF 15 TO 20 KNOTS WILL PROVIDE AN
ELEVATED RISK OF WILDFIRE SPREAD ALONG AND WEST OF HIGHWAY 281 THIS
AFTERNOON. WILL ISSUE AN RFD TO ADDRESS THE WILDFIRE SPREAD
POTENTIAL.
