Synopsis for the Gulf of Mexico

.SYNOPSIS...A frontal boundary has stalled across the NW
Caribbean. A sharp surface trough extends from the Yucatan
Peninsula near 19.5N91W to 1017 mb low pres near 21N95W to
extreme S Texas. High pressure to the north of the area is
supporting strong winds to the north of the trough to 27N, and
to the W of the trough to the Mexican coast. The low and trough
will drift N over the weekend. The pressure gradient between
this low pres and new high pres across the south-central U.S.
will strengthen the winds and produce strong to gale force winds
across much of the Gulf of Mexico Sat afternoon through Sun
night. Conditions will improve modestly on Mon and then
significantly Tue through Wed.
