COASTAL WATERS FORECAST FOR TEXAS
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
323 PM CDT SAT JUL 12 2014

UPPER TEXAS COASTAL WATERS FROM HIGH ISLAND TO THE MATAGORDA SHIP
CHANNEL OUT 60 NAUTICAL MILES INCLUDING GALVESTON AND MATAGORDA BAYS

GMZ300-130915-
SYNOPSIS FOR HIGH ISLAND TO THE MATAGORDA SHIP CHANNEL OUT 60
NAUTICAL MILES INCLUDING GALVESTON AND MATAGORDA BAYS
323 PM CDT SAT JUL 12 2014

.SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM...
A SURFACE RIDGE OF HIGH PRESSURE WILL MAINTAIN A PREVAILING LIGHT
ONSHORE FLOW OVER THE NORTHERN GULF OF MEXICO FOR THE NEXT FEW DAYS.
THE PRESSURE GRADIENT IS LIGHT ENOUGH THAT WE WILL CONTINUE TO SEE A
DIURNAL LANDBREEZE/SEABREEZE EFFECT THROUGH THE EARLY PART OF NEXT
WEEK.

SEVERAL WEAK UPPER LEVEL DISTURBANCES WILL CROSS THE UPPER TEXAS
COASTAL WATERS OVERNIGHT AND AND ON SUNDAY.  HOWEVER...AT THIS
TIME...MOST MODELS SUGGEST THAT THE SURFACE RIDGE WILL CONTINUE
TO LIMIT SHOWER AND THUNDERSTORM DEVELOPMENT.

THE PRESSURE GRADIENT SHOULD TIGHTEN BY THE MID TO LATTER PART OF
NEXT WEEK WHICH WILL PRODUCE A MORE MODERATE ONSHORE FLOW BY
WEDNESDAY NIGHT...CONTINUING IN TO THE WEEKEND.
