Discussion
A cold front will slowly make its way through the area this
evening. Cloudy skies will continue through the evening hours but
we should clear out north to south, and you should feel a
temperature difference in the morning as temps should be in the
50s in the morning. Highs will only reach the lower 70s on
Thursday under clear conditions. As we move into Friday, all
guidance points to a surface low developing in the gulf and moving
towards the southeast united states. The national hurricane
center highlights an area with 50 percent chance of development
over the next few days. Impacts from this system will be highly
dependent on the track of the low. All guidance suggests that the
bulk of the rain and stronger onshore winds will be offset to the
east of the center of circulation. Today, guidance showed a little
bit of an eastward trend from guidance from earlier. This would
favor a drier solution for our forecast area. Confidence is
building with respect to tides moving higher than normal by Friday
with the highest values into the weekend due to the path of the
sfc low over the northern gulf and its fetch over the eastern half
of the gulf. For right now, have slightly favored an eastward
track in the forecast. This forecast is still a very fluid
situation and could change drastically as the surface low
circulation has not developed yet, and models tend to struggle
with unorganized systems. We will have to watch the evolution of
this over the next 24 hours to get a better handle on the
situation. There will be a tight rain gradient over the region and
which side we are one depends on the track. The system should
push out of the area Saturday night and return flow ahead of the
next cold front should begin once again by late Sunday. This front
should move through the area Monday night.

Aviation
MVFR conditions to prevail through at least 6z. After 6z
conditions should improve from north to south toVFR conditions.

Winds will pick up out of the north at 10 to 20 knots as a cold
front moves through the area this evening.

Marine
A cold front will slowly push through the coastal waters this
evening. Exercise caution is in effect for the entire coastal
waters through Thursday morning. We will have to watch for a
possible upgrade this evening if winds exceed expectations. A
strong low pressure system will then impact the coastal waters on
Friday night and Saturday. Fully expect to see small craft
advisory conditions develop by Friday evening and persist into
Saturday evening. We will have to monitor for possible upgrades
to gale warnings or tropical type products if needed. Winds of 20
to 30 knots and seas of 6 to 12 feet will be possible. High
pressure should quickly build over the waters as the low departs
on Sunday allowing for lighter winds of around 10 knots and seas
of 2 to 4 feet to take hold. However, another low pressure system
and cold front will approach the waters on Monday resulting in
increased onshore flow of 15 to 20 knots.
