Southeast Gulf of America

.SYNOPSIS...A ridge extending from SW Florida to near Houston
Texas combined with lower pressures over central Texas and
Mexico will maintain moderate winds across the basin ahead of a
cold front. The weak cold front will move into the northern Gulf
tonight, stall, then lift north and dissipate through Wed night.
Another weak front will sink into the NE Gulf Thu through Thu
night then dissipate. High pressure is expected to move into the
NE Gulf this coming weekend and dominate the basin. Winds may
freshen in the western Gulf starting Sat night. E winds will
pulse fresh to locally strong along and just north of the
Yucatan Peninsula each afternoon and evening through the period
as a trough develops daily and drifts westward at night. Smoke
from agricultural fires in southeastern Mexico will continue to
maintain hazy sky conditions across the western Gulf through the
period.

.SYNOPSIS...A frontal trough from near 31N63W to 28.5N69W will
shift moderate to fresh winds ahead of it. A pair of frontal
troughs may move across the northern waters later in the week
