Synopsis for the Gulf of Mexico
1024 AM EDT Sun Oct 21 2018

.SYNOPSIS...A cold front extends from N central Florida to 28N89W
and to 27N93W, where it becomes a warm front to a weak 1016 mb
low over the NW Gulf near 27N96W. A stationary front then trails
from the low to 23N96W to 20N97W. The cold front will sweep
across the eastern and central Gulf waters today and and become
a stationary front over the SE Gulf on Mon. The low will slowly
move northeastward through Mon night, then east-northeastward
across the north-central waters through Thu night and the NE Gulf
by Fri, dragging a new cold front across the SW Gulf. The
pressure gradient between the low and high pressure building over
the southeastern United States will support fresh to strong north
to northeast winds and building seas over the northern Gulf today
before diminishing Mon. Fresh to strong northerly winds are also
expected over the western Gulf behind the cold front. On Mon,
fresh to strong north to northeast winds over the NW Gulf will
lowly diminish through Thu.
