.SYNOPSIS...A cold front has entered the northern Gulf, and will
continue moving quickly across the basin while weakening. High 
pressure will build in the wake of the front. Fresh southerly 
return flow will set up over the western Gulf tonight through 
Tue night ahead of the next cold front forecast to reach the 
northern Gulf late on Wed, then stall and lift northward Thu. 
Looking ahead, a third and stronger cold front is expected to 
move across the Gulf waters over the weekend.
