Synopsis for the Gulf of Mexico

.SYNOPSIS...A stationary front extends from near Sarasota,
Florida to 24N90W to a 1014 mb low at 21N95W. The stationary
front will transition back to a cold front reaching the far
southeastern Gulf Wed night. The low is forecast to lose its
identity along the front by early Wed. Scattered showers and
thunderstorms will be focused along and near the front tonight
into Wed morning. Some of this activity may produce strong gusty
winds and rough seas. High pressure in its wake will shift
eastward through Sat night as a cold front reaches eastern
Texas. Fresh to strong southerly return flow will develop over
the NW Gulf Fri, shift to the central Gulf early Sat and
diminish by late Sat as the cold front moves across the NW Gulf
and central Gulf waters. The front will become stationary from
the east- central Gulf to the west-central Gulf Sun and Sun
night as a weak gradient sets up over the area.
