Synopsis for the Gulf of Mexico

.SYNOPSIS...High pres extending from the middle Atlantic 
region of the United States southward to the eastern gulf waters 
will move eastward through Tuesday as a strong cold front moves 
across the central portion of the  U.S. and approaches the NW 
gulf waters. The cold front will enter the NW gulf Tuesday night 
followed by fresh to strong northerly winds and building seas. 
The cold front will reach from near Apalachee Bay to near 27N90W 
and to 26N93W where it will transition to a warm front to 
developing low pres near far southern Texas coast. A cold front 
will extend from the low southward to the far western part of 
the SW gulf on Wednesday. The low pres is expected to move 
quickly northeastward dragging the cold front across the 
remainder of the Gulf through Friday. Strong northerly winds and 
rapidly building seas will follow the front, with winds possibly 
reaching gale force over portions of the west-central and SW 
waters beginning on Thursday and through Thursday night. Strong 
NE winds with frequent gusts may occur over the far NW waters on 
Wednesday. High pres will build in over the area in the wake of 
the front.
