AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
256 PM CDT MON JUL 27 2015

.DISCUSSION...
SEE NO SIGNIFICANT CHANGES TO THE FORECAST FOR THIS AFTERNOON`S PACKAGE
AS THE ENTIRE AREA REMAINS VERY WARM AND A MAJORITY OF THE AREA REMAINS
DRY. SO FAR THIS AFTERNOON...A COUPLE SHOWERS DEVELOPED IN BRAZORIA
COUNTY AND WE CONTINUE TO WATCH ACTIVITY OFF TO OUR EAST. A COUPLE MORE
HOURS OF HEATING IN COMBINATION WITH ANY WEAK BOUNDARIES (IN THE AREA
OR APPROACHING FROM THE EAST) COULD BRING SOME SHOWERS AND THUNDERSTORMS
TO SOME LUCKY SPOTS. TOMORROW AND WEDNESDAY STILL LOOK DRY FOR A MAJORITY
OF SOUTHEAST TEXAS. RAIN CHANCES COME BACK INTO THE FORECAST BEGINNING
ON THURSDAY AS SOME DEEPER MOISTURE TRIES TO MOVE INTO THE AREA WHILE
THE UPPER LEVEL RIDGE REPOSITIONS ITSELF TO THE WEST. HOWEVER...THE
BEST COVERAGE DURING THE THURSDAY THROUGH SUNDAY TIME PERIOD MIGHT END
STAYING NEAR THE COAST AND ACROSS THE GULF WATERS AND MIGHT NOT MAKE
IT VERY FAR INLAND WHERE STRONGER SUBSIDENCE WILL BE FOUND. FOR HIGH
TEMPS...WILL CONTINUE TO CARRY HIGHS MAINLY IN THE MID TO UPPER 90S
INLAND AND IN THE LOWERS 90S AT THE COAST. IT IS NOT OUT OF THE QUESTION
THAT A FEW INLAND SPOTS COULD REACH OR EXCEED THE CENTURY MARK. FOR
LOW TEMPS...WILL CONTINUE TO CARRY MID TO UPPER 70S INLAND AND LOWER
LOWER 80S AT THE COAST. PEAK HEAT INDEX VALUES MAINLY IN A 101 TO 107
RANGE WILL PERSIST TOO...AND WILL CONTINUE TO COVER THE ONGOING HEAT
ISSUES WITH A SPECIAL WEATHER STATEMENT AND SOCIAL MEDIA AVENUES.

IF SOME OF OUR MAJOR CLIMATE SITES STAY DRY THROUGH THE END OF THE MONTH...
JULY 2015 WILL MAKE IT INTO THE TOP 10 LISTS. WITH THE FIVE DAYS LEFT
IN THE MONTH...HOUSTON IAH`S 0.44 INCHES WOULD RANK AS THE 2ND DRIEST
JULY ON RECORD...AND GLS`S 0.23 INCHES WOULD RANK AS THE 7TH DRIEST
JULY ON RECORD. GLS ALSO HAS A CHANCE TO END UP HAVING ONE OF THEIR
WARMEST JULYS ON RECORD. THE CURRENT AVERAGE TEMPERATURE OF 86.3 DEGREES
WOULD END UP BEING THEIR 4TH WARMEST JULY ON RECORD.

.MARINE...

LIGHT TO OCCASIONALLY MODERATE ONSHORE WINDS ARE EXPECTED TO
CONTINUE THROUGH THE REMAINDER OF THE WEEK... INCREASING SLIGHTLY
DURING THE OVERNIGHT HOURS. A WEAK COLD FRONT IS EXPECTED TO
APPROACH SOUTHEAST TEXAS ON THURSDAY... WITH INCREASING CHANCES FOR
SHOWERS AND THUNDERSTORMS OVER THE COASTAL WATERS AS THE FRONT NEARS
THE COAST. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE OVER THE
COASTAL WATERS THROUGH THE END OF THE WEEKEND IN THE VICINITY OF
THIS BOUNDARY BEFORE THE BUILDING INFLUENCE OF THE UPPER RIDGE
LIMITS DEVELOPMENT.
