.SYNOPSIS...

Southerly flow courtesy of high pressure centered off the Carolina
coast will prevail over the northern Gulf of Mexico for the
remainder of the work week. Elevated winds will continue into
mid-week as low pressure moves into the southern Plains,
tightening the pressure gradient...small craft should use caution.
Occasional passing disturbances aloft will provide rounds of
