Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extends from near Tampa Bay, Florida to 
the SW Gulf stalls to the central Bay of Campeche. Weak low 
pressure ahead of the front in the SE Gulf will weaken as it 
moves southeast early today. The front will sweep southward 
across the SE Gulf into the Straits of Florida by tonight, except
lifting northward over the western Gulf ahead of low pressure 
moving through northeast Mexico. The front may lift northward 
early Tue as a warm front while the low pressure moves into the 
north-central Gulf. A trailing cold front over the western Gulf 
will dissipate through mid week. Looking ahead, a stronger cold 
front may move off the Texas coast into the far northwest Gulf Thu
night followed by near-gale or gale force winds and building 
seas.
