including Galveston and Matagorda Bays.
Light winds and low seas will prevail for the next several days.
That said mariners should be on the lookout for scattered scattered
showers and thunderstorms 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
in the mornings through early afternoon. 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.
