AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
136 PM CDT SUN APR 10 2011

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...HAVE KEPT THE
PREVIOUS FORECAST PRETTY MUCH IN TACT EVEN WITH THE MODEL GUIDANCE
BACKING OFF ON MONDAY/S WINDS AND DEW POINT FALLS. WARM AND SULTRY
IN ADVANCE OF THE COLD FRONT THAT IS EXPECTED TO MOVE THROUGH THE
CWA MONDAY MORNING. WINDS AND SOME DEVELOPMENT OF STRATUS TO KEEP
TEMPERATURES WELL ABOVE NORMAL. TIMING OF THE FRONT AND DRIER AIR
INTRUSION WILL BE CRITICAL FOR FIRE WEATHER HAZARDS. HAVE OPTED TO
UPGRADE THE FIRE WEATHER WATCH FOR THE AREAS WEST OF HIGHWAY 281
TO A RED FLAG WARNING AND UP THE TIME TO 10 AM. DRIEST AIR AND
PEAK WINDS NOT EXPECTED IN HIDALGO COUNTY UNTIL BETWEEN NOON AND 2
PM BUT DID NOT WANT TO ADD ANY CONFUSION ON THE HEADLINES. ALSO
INTRODUCED A FIRE WEATHER WATCH FOR THE COASTAL COUNTIES WITH WEST
PORTIONS OF THE COUNTIES LIKELY TO SEE APPROACHING CRITICAL
CONDITIONS FOR AT LEAST A FEW HOURS. FIRES TODAY ALONG HIGHWAY 77
NEAR HIGHWAY 100 ALSO RAISE CONCERNS FOR MONDAY. ANY MORNING
CLOUDS SHOULD RAPIDLY DISSIPATE AS THE LOWER DEWPOINTS INVADE THE
AREA DESPITE WHAT THE MODELS INDICATE. TEMPERATURES ALSO WARMER
THEN GUIDANCE AS THE DRY AIR HEATS UP WITH ADDED DOWNSLOPING
COMPRESSION. DID LOWER MONDAY NIGHT TUESDAY MORNING TEMPERATURES A
FEW DEGREES WITH THE DRY AIR IN PLACE AND LIMITED RELATIVE
HUMIDITY RECOVERY.

.LONG TERM /TUESDAY THROUGH SUNDAY/...BY TUESDAY THE FRONT SHOULD
BE THROUGH THE AREA. HIGH PRESSURE AT THE SURFACE WILL BE SINKING
SOUTH OVER MUCH OF EAST TEXAS...PLACING DEEP SOUTH TEXAS UNDER
WEAK EASTERLY FLOW. IN THE MEANTIME...WEAK UPPER LEVEL RIDGING
WILL BE BUILDING OVER THE AREA AS THE UPPER TROUGH CONTINUES TO
PUSH EAST OVER THE EASTERN STATES. TEMPERATURES WILL BE SLIGHTLY
COOLER ON TUESDAY BEHIND THE COLD FRONT...REMAINING IN THE MID AND
UPPER 80S FOR MOST LOCATIONS FOR HIGHS.

MOVING INTO WEDNESDAY...THE HIGH WILL CONTINUE TO SHIFT TO THE EAST
AS A WEAK DISTURBANCE BEGINS TO DEVELOP OVER THE LOWER PLAINS.  THIS
WILL ALLOW FOR SOUTHEASTERLY LOW LEVEL FLOW TO RETURN TO DEEP SOUTH
TEXAS.  THIS WILL PERSIST THROUGH THE REMAINDER OF THE WORK
WEEK...ALLOWING FOR ABOVE NORMAL TEMPERATURES TO RETURN AS WELL AS
SOME MOISTURE.

ON FRIDAY...A WEAK COLD FRONT WILL APPROACH THE FORECAST AREA.  FOR
THE MOST PART...THIS FRONT APPEARS TO BE DRY.  HOWEVER...HAVE
CONTINUED SOME MENTION OF VERY SMALL POPS FOR LIGHT RAIN FOR NOW.
OTHERWISE...THE FRONT IS EXPECTED TO RATHER WEAK...AND IS NOT
EXPECTED TO BRING MUCH EFFECTS TO DEEP SOUTH TEXAS.

&&

.MARINE...TONIGHT THROUGH MONDAY NIGHT...WINDS HAVE BEEN BEHAVING
AS EXPECTED THIS AFTERNOON WITH SCA OVER THE BAY AND SCEC ACROSS
THE OFFSHORE WATERS. BELIEVE THIS WILL REVERSE TONIGHT. GRADIENT
TO REMAIN TIGHT OVERNIGHT PUSHING WINDS AND SEAS OFFSHORE THAT
EXTRA NOTCH. SMALL CRAFT ADVISORIES HAVE BEEN ISSUED FOR THE
OFFSHORE WATERS FROM 10 PM TONIGHT THROUGH 10 AM MONDAY. GRADIENT
TO WEAKEN MONDAY MORNING AS FRONT APPROACHES THE COASTAL WATERS.
PASSAGE IS LIKELY IN THE AFTERNOON WITH NORTH WINDS BECOMING
MODERATE. SEAS TO MIX WITH THE SOUTH SWELL THEN SLOWLY LOWER INTO
THE EVENING. A FEW SHOWERS OR EVEN AN ISOLATED THUNDERSTORM IS
POSSIBLE MONDAY AFTERNOON.

TUESDAY THROUGH SUNDAY...LIGHT TO MODERATE EAST TO SOUTHEAST LOW
LEVEL FLOW WILL PERSIST THROUGH THE LONG TERM PORTION OF THE
FORECAST OVER THE LOWER TEXAS COASTAL WATERS.  AS SUCH...SEAS WILL
REMAIN MODERATE THROUGH THIS TIME PERIOD AS WELL. THIS WILL RESULT
AS HIGH PRESSURE WILL SIT TO THE NORTH AND EAST OF THE AREA OVER THE
NORTHEASTERN GULF OF MEXICO AND SOUTHEASTERN STATES.  THESE
CONDITIONS WILL PERSIST THROUGH THURSDAY BEFORE ANOTHER WEAK COLD
FRONT APPROACHES ON FRIDAY.  OTHERWISE...CONDITIONS SHOULD REMAIN
BELOW SCA CRITERIA...HOWEVER WILL NOT RULE OUT THE NEED FOR PERIODS
OF SCEC DUE TO WINDS.

&&

.FIRE WEATHER...ONCE AGAIN UPGRADED THE FIRE WEATHER WATCH TO A RED
FLAG WARNING FOR THE WESTERN TWO THIRDS AND ADDED THE EASTERN
COUNTIES INTO A FIRE WEATHER WATCH.  MAIN LIMITING FACTOR WILL BE
WINDS AND DURATION OF THE STRONGEST WINDS. IF SKIES CLEAR AS THE
FRONT PASSES ADDED MIXING OF THE BOUNDARY LAYER SHOULD PUSH
SUSTAINED WINDS TO 20 MPH WITH SOME GUSTS UP TO 30 MPH.
