.SYNOPSIS...
Light offshore flow will prevail through Saturday. Isolated to scattered
showers and thunderstorms will return by Saturday as Gulf moisture
slowly moves northward. Precipitation chances increase significantly
Sunday through most of next week as additional moisture from the Southern
Gulf of Mexico advances northward. East to southeast winds expected
to increase near or above 20 knots, along with increasing seas, beginning
Monday, and remain near this level for the remainder of the period.
This prolonged east to southeasterly fetch will likely cause increasing
tides, with minor coastal flooding possible. Small Craft Advisories
will be likely necessary during this time period.
