Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure ridging extending from the Atlantic to
the central Gulf will slide ESE today as a cold front approaches
the Texas coast. The front will move over the NW Gulf this
afternoon. Tonight the front will stall from 29N83W to a low
pressure near 27N93W. A cold front will extend from the low to
Tamiahua, Mexico with strong to near gale force winds behind,
rapidly reaching gale force through Tue evening as the tail of
the front reaches the central Bay of Campeche. The stationary
front will transition to a warm front that lifts north of the
Gulf late on Tue, and the cold front will weaken as it reaches
the central Gulf Tue night into Wed, the southeastern Gulf
during Wed and east of the Gulf late Wed night. In the wake of
this front, high pressure will shift eastward across the
northern and central Gulf Fri and Fri night as another low forms
along a front that may possibly enter the NW and north- central
Gulf areas.
