Onshore winds will prevail ahead of an approaching frontal system
Saturday. Scattered showers and thunderstorms with large hail,
frequent cloud to water lightning and heavy downpours may develop
over nearshore waters in the late afternoon. The boundary will send
widespread showers and storms across the north Gulf from late
Saturday through Sunday. Heavy downpours and embedded storms with
lightning and gusty winds will be the primary concern overnight into
Sunday.
The next weather system moves into Texas early in the week and a
prolonged period of building winds and seas is expected Monday thru
the midweek.
