GMZ001-210800- Synopsis for the Gulf of Mexico 400 PM EDT Tue Apr 20 2021 .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. $$ GMZ011-210800- NW Gulf including Stetson Bank- 400 PM EDT Tue Apr 20 2021 .TONIGHT...NE winds 10 kt.
