Synopsis for the Gulf of Mexico

.SYNOPSIS...A surface trough is expected to take shape today,
and extend from near the Yucatan Peninsula north-northeastward
to the Florida Big Bend by tonight. Surface low pressure could
form along this trough today or Thu and is expected to meander
over the eastern Gulf through Fri. Environmental conditions
appear only marginally favorable for additional development
during this time. Enhanced showers and thunderstorms are
expected across most of the eastern half of the Gulf today into
Fri. Winds associated with this system are forecast to be fresh
over the NE Gulf beginning tonight. The system should move
eastward over Florida and into the Atlantic Ocean during the
weekend. Elsewhere, over the western Gulf, high pressure should
lead to gentle to moderate winds into the weekend, with
occasional fresh pulses along the W coast of Yucatan.
