.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.

Light winds and low seas will prevail for the next several days.
Scattered showers and storms will be possible on a daily basis as
upper level disturbances pass through the region. While
widespread severe storms are not anticipated, the potential is
there for a few embedded stronger storms capable of producing wind
gusts to 30 knots, frequent lightning, and heavy downpours. The
best chances will be in the morning through early afternoon hours.
Usually in this type of pattern, rain chances are generally
better offshore in the late night and morning hours, in the bays
mid morning into the afternoon hours...though timing of upper
disturbances could alter those at times.
