.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

Broad surface ridge centered over the Ohio River Valley is steadily
moving eastward. As it does so, offshore winds will be rotating
around to east and then southeast through the early morning hours.
Farther west, an upper level low is located near the 4-Corners
region. It will be quickly moving eastward and into the Central
Plains by late in the day today. A surface low will develop in the
vicinity of the upper low and follow its path into OK and KS. The
local pressure gradient will tighten in response to that feature.
Thus, expect the southerly winds to increase to at least Exercise
Caution speeds from west to east over the coastal waters late this
aftn/evn. Models show BL winds peaking in the low 20s around 06Z on
Tuesday and quickly falling off to 15kts or less by mid morning
Tuesday. May need to issue a short term Small Craft Advisory for
open Gulf waters. 48 hours after that, another (stronger) cold front
will push through the region. The upper trough looks to be much
deeper and broader which will likely translate to stronger winds
that persist longer than 12 hrs.
