AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
342 PM CDT THU SEP 29 2011

.DISCUSSION...
SCATTERED THUNDERSTORMS HAVE DEVELOPED ACROSS CNTL PARTS OF THE
CWA AND ARE ASSOCIATED WITH THE OUTFLOW BOUNDARY PRODUCED BY THIS
MORNINGS STORMS NEAR THE COAST. EXPECTING THESE STORMS TO CONTINUE
INTO THE EVENING HOURS UNTIL TEMPERATURES SUBSIDE. SEEING SOME
ELEVATED CORES ON RADAR SO CAN'T RULE OUT SOME ISOLATED DOWNBURSTS
AND/OR HAIL. MAY ALSO SEE SOME STORM/SEABREEZE COLLISIONS.
OTHERWISE...A COLD FRONT IS EXPECTED TO PUSH INTO THE NORTHERN
PORTIONS OF SOUTHEAST TEXAS LATE TONIGHT. THIS MAY PROVIDE ANOTHER
FOCUS FOR SHOWER AND THUNDERSTORM DEVELOPMENT ALONG AND TO THE
SOUTH OF THE BOUNDARY AS NAM12 & GFS DEPICT. HOWEVER...SUSPECT THE
ATMOS MAY BE WORKED OVER FROM THIS AFTN/EVNGS STORMS TO KEEP
OVERALL COVERAGE LESS THAN THE MODELS DEPICT. MOST AREAS SHOULD
SEE OFFSHORE WINDS BY MID MORNING BUT DRIER AIR WILL BE A BIT
SLOWER TO FILTER IN (COASTAL AREAS PROBABLY WON'T FEEL MUCH OF A
DIFFERENCE UNTIL LATE FRI AFTN OR EVENING).

VERY NICE WX EXPECTED INTO AT LEAST THE MIDDLE PART OF NEXT WEEK.
HIGH PRES WILL GENERALLY BE CENTERED ACROSS THE SOUTHEASTERN
UNITED STATES BUT E/NE WINDS SHOULD KEEP THE GULF SHUT OFF AND
DRY AIR IN PLACE. ONSHORE WINDS SHOULD RESUME DURING THE SECOND
HALF OF NEXT WEEK...ALLOWING A GRADUAL RETURN OF CLOUDS/MOISTURE
AND WARMER TEMPS. 47

&&

.MARINE...
ANOTHER CHANCE FOR THUNDERSTORMS TONIGHT. EXPECTING A FRONT TO MOVE
OFF THE COAST FRIDAY MORNING. WINDS UP TO CAUTION CRITERIA ARE
POSSIBLE BY FRIDAY EVENING AND ADVISORY CONDITIONS MAY DEVELOP

GRADUALLY DIMINISH OVER THE WEEKEND.  40

&&

.FIRE...
ELEVATED FIRE WEATHER CONDITIONS WILL DEVELOP BEHIND A COLD FRONT
THAT WILL MOVE THROUGH THE AREA TONIGHT AND EARLY FRIDAY. ALTHOUGH
THE MINIMUM RELATIVE HUMIDITY VALUES WILL DROP BELOW 30 PERCENT FOR
MOST AREAS AWAY FROM THE COAST...THE WIND SPEEDS WILL LIKELY AVERAGE
BELOW 15 MPH. HOWEVER...THERE MAY BE PERIOD OF A FEW HOURS WORTH OF
15 TO 20 MPH WIND SPEEDS FOLLOWING THE FRONT LATE FRIDAY MORNING
INTO THE AFTERNOON.  40
