Synopsis for the Gulf of Mexico
1115 PM EDT Tue Apr 20 2021
.SYNOPSIS...A stationary front extends from Sarasota, Florida, SW
to the Bay of Campeche, connecting to a 1010 mb low pressure. The
stationary front will transition back to a cold front reaching
the far southeastern Gulf late Wed. 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.
