GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 319 Pm Cst Thu Feb 22 2018
Synopsis..Fog, possibly dense at times, reforms tonight over area bays and sounds. A light to moderate onshore flow continues through Saturday night in response to a strong surface ridge of high pressure located off the mid atlantic coast. A cold front settles southeast and reaches the northern gulf coast Sunday and begins to stall over the northern gulf waters early next week. With the front in the area, chances of showers will be on the increase through the weekend with perhaps the passage of a few storms.

323 pm est Thu feb 22 2018

Near term [through tonight]
Sfc ridge will continue across the deep south with south to
southeast winds across the forecast area. Dry air aloft and more
than adequate moisture with current dewpoints in the 60s will allow
for patchy to areas of fog late tonight and potential for low clouds
as well. Have tweaked mins down a bit but generally expect lows to
bottom out 60-65 to a few upper 50s similar to this morning.

Short term [Friday and Saturday night]
Deep layer ridge will slowly be shifting eastward resulting in more
southerly low level flow developing by Saturday. Slightly higher
mainly layer moisture will begin edging eastward into the portions
of the fl panhandle and southeast al Saturday but not enough to
warrant mention of showers due largely to dry air aloft. The large
ridge affecting the region will continue the pattern of warm and
generally dry weather. High temps in the lower to mid 80s with lows
in the lower 60s with some patchy fog possible. By Saturday
night... Large mid to upper level trough over the central conus
pushes ewd as shortwave energy moves into the tn and ohio valley
areas. This will help bring a cold front to from central tn to the
lower ms valley by early Sunday morning. Continued with a low chance
of showers over the WRN zones as moisture ahead of the front
supports a few showers. Warmer overnight lows in the lower to middle
60s expected.

Long term [Sunday through Thursday]
As mid-upper level trough and cold front move into the area Sunday
and Monday elevated rain chances are expected. Some instability will
lead to chances of isolated thunderstorms along with the showers
from Sunday into Monday. A weak wave of low pressure may develop
Monday over al and ga and move northeastward. This low pressure will
help drive the front southeastward but upper level flow becomes less
conducive for ascent as main energy shifts northeast. By Monday
night into Tuesday... 500 mb heights become more zonal and the front
will stall over northeast gulf waters with sfc high pressure builds
north of the area. Lower rain chances anticipated during this period.

Front may work back northward Wed and Thu with a low chance of
showers anticipated again. Highs in the upper 70s to lower 80s are
possible again on Sunday, with highs mainly in the 70s next week
after the front moves slightly south of our area though could see
highs reach around 80 again by Thursday south-southwest low level
flow develops as front pushes back north of the area.

Aviation [through 18z Thursday]
Sct-broken cumulus rest of today which should mostly dissipate in
the evening hours. Restrictions expected late tonight and early
Friday with tafs for now showing MVFR and ifr from about 09z-14z.

Greatest chance ifr seem to be around vld and aby. Cannot rule out
some further restrictions to lifr range as shown by some of the
guidance.

Marine
Easterly to southeasterly winds from 10 to 15 knots will prevail
through Saturday... With more southerly flow Sunday ahead of the next
cold front. Cold front will move into area waters Sunday night into
Monday which will then stall then move back northward by mid week.

Seas will generally range from 2 to 4 feet with highest seas across
our southwestern marine zones.

Fire weather
No fire weather concerns are anticipated through the next several
days as high rh values persist across our area.

Hydrology
Little to no rainfall is expected for the next few days. The next
chance of moderate to heavy rainfall will be from Sunday through
Monday, mainly across northern and western parts of our area.

However, latest models have decreased projected rainfall totals
during this period, so widespread flooding does not appear likely.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.
