Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front across the N Gulf coastal waters from
the Big Bend region to 27.5N95W to 24.5N97.5W and will extend
from N central Florida to near 27N90W to Tampico, Mexico Thu
morning. Meanwhile, 1008 mb low pres near 21N95.5W will allow
strong N winds to spill southward across the Mexican coastal
waters. The front will meander across the N Gulf through Fri
before becoming diffuse, while the low moves slowly NE and
becomes better organized. Strong to near gale force winds will
surround the low on Fri with gale force wind expected across E
portions of the low Fri night and Sat. This low has a medium
chance to develop into a tropical or subtropical cyclone late
this week.
