AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
334 AM CDT MON MAY 30 2011

.DISCUSSION...
ANOTHER BREEZY/MUGGY NIGHT ACROSS SE TX AGAIN TONIGHT WITH THE
TIGHT PRESSURE GRADIENT STILL IN PLACE. LOW CLOUDS ARE FORMING
OVER SE TX ONCE AGAIN WHILE CIRRUS ANVIL BLOW OFF FROM EARLIER
STORMS NEAR THE RIO GRANDE IS PUSHING ACROSS THE AREA. THE STRATUS
WILL MIX OUT BY MID MORNING WITH PARTLY TO MOSTLY SUNNY SKIES THIS
AFTN. TEMPERATURES SHOULD AT OR POSSIBLY A DEGREE OR TWO LOWER
THAN YESTERDAY. STRONG SOUTH TO SOUTHEAST WINDS WITH FREQUENT
GUSTS OVER 30 MPH ARE EXPECTED TODAY (ALREADY GUSTING TO 33 MPH AT
GALVESTON)...SO WILL POST ANOTHER WIND ADVISORY FOR THE WESTERN
HALF/COASTAL ZONES. THE GUSTY WINDS AND DRY FUELS COMBINED WITH A
LOT OF OUTDOOR ACTIVITIES WILL KEEP THE WILDFIRE THREAT GOING
ESPECIALLY OVER THE NRN HALF OF THE AREA. WILL KEEP THE RIP
CURRENTS STATEMENT IN PLACE (SATCFWHGX) AND ALSO THE FIRE DANGER
STATEMENT (SATSPSHGX). TEMPS WILL REMAIN WELL ABOVE NORMAL TONIGHT
WITH THE LAST ROUND OF STRATUS DEVELOPMENT EXPECTED AS A 30 KT LOW
LEVEL JET REMAINS IN PLACE OVER THE AREA. SFC WINDS WILL BE LOWER
ON TUESDAY AS LOW PRESSURE LIFTS FROM THE PLAINS TO THE GREAT
LAKES AND THE PRESSURE GRADIENT SLACKENS OVER THE AREA. A BIT MORE
CLOUD COVER IS EXPECTED AS WELL...WITH MAX TEMPS CLOSE TO TODAY'S
LEVELS.

CHANGES IN THE UPPER AIR PATTERN TAKE PLACE TOWARD THE MIDDLE AND
LATTER PART OF THE WEEK WITH A SUMMER-LIKE REGIME TAKING SHAPE OVER
THE GULF COAST REGION. HIGH PRESSURE AT THE SURFACE AND ALOFT OVER
THE SOUTHEAST WILL RETROGRADE WEST ACROSS THE AREA BY WEDNESDAY.
LOW LEVEL FLOW WILL BECOME VERY LIGHT BY WEDNESDAY LASTING THROUGH
THE WEEKEND...WITH THE TYPICAL LAND BREEZE/SEABREEZE INTERACTION
DEVELOPING EACH DAY. THE COMBINATION OF CLEAR SKIES...LOWER
DEWPOINTS AND LIGHT WINDS WILL RESULT IN COOLER OVERNIGHT LOW
TEMPERATURES THIS PERIOD. HOWEVER...HIGHS WILL REMAIN SEVERAL
DEGREES ABOVE NORMAL DUE TO THE PRESENCE OF THE UPPER RIDGE. GFS
BUFR SOUNDINGS SHOW A BREAKABLE CAP EACH DAY. HOWEVER...MOISTURE
WILL BE SEVERELY LACKING (PWS GENERALLY BELOW 1.2 INCHES). AS A
RESULT...HAVE CHOSEN TO LEAVE PRECIP OUT OF THE FORECAST THROUGH
DAY 7. LATEST RUNS OF THE GFS/ECMWF SHOW THE UPPER RIDGING
WEAKENING THIS WEEKEND AS A TUTT LOW DEVELOPS OVER THE WESTERN
GULF. MAX TEMPS SHOULD BEGIN TRENDING DOWNWARD THIS WEEKEND INTO
EARLY NEXT WEEK. IF THIS PATTERN CHANGE PANS OUT THEN WE WILL SEE
THE POTENTIAL FOR SOME SEABREEZE CONVECTION BY EARLY NEXT WEEK.

SPRING 2011 (MARCH THROUGH MAY) WILL FINISH AS THE DRIEST SPRING
OF ALL-TIME FOR HOUSTON...AND THE FIRST OR SECOND WARMEST SPRING
ON RECORD AS WELL. SEE CLIMATE SECTION BELOW FOR AN INITIAL BRIEF
SUMMARY.
