Synopsis..High pressure will continue to shift east to the eastern seaboard and western atlantic through Saturday in response to a strong cold front approaching from the west. The cold front will move across the marine area late tonight through Sunday morning leading to a strong offshore flow occurring throughout most of the day on Sunday. Northerly winds and seas will gradually subside Sunday night through early Monday. Frequent gusts to gale force, occurring mostly over the open gulf waters, will also be possible in the wake of the front early Sunday.

06z issuance...VFR condition through about 18.09z for bfm, and
through about 18.10z for pns. MVFR visibilities (5sm) already
being reported at mob. MVFR ceilings (2500 to 3000 feet) will
then occur after these times at all TAF sites through early
Saturday morning as low clouds develop. Both pns and bfm should
see ceilings rise to back toVFR levels (3500 feet) though early
Saturday evening, but mob should stay at MVFR levels (3000 feet).

MVFR ceilings (2500 to 3000 feet) will then occur at all taf
sites through the remainder of the forecast, along with showers in
the vicinity. Winds will be mostly south to southeast at 5 to 8
knots through early Saturday morning, increasing from the south to
southwest 12 to 16 knots through 19.06z. 22

Prev discussion issued 349 pm cst Fri nov 17 2017
near term now through Saturday ... A broad upper ridge of high
pressure over texas and northern mexico, stretching east over the
western gulf, will shift south through Sat afternoon in response to
a vigorous short wave trough and surface cold front moving eastward
from the central rockies to the mid to lower mississippi river
valleys through Sat afternoon. This system remains progressive and
positively tilted through Sat afternoon with limited forcing in the
mid levels further south along the northern gulf coast through sat
afternoon. Near the surface a closed low tracks east across the
central plains to south of the great lakes with the attendant cold
front reaching the ms la border by late Sat afternoon. With this
pattern expect increasing clouds tonight through Sat afternoon with
a slight chance of rainshowers for most areas by Sat afternoon. A
light southeast wind will become better developed late this
afternoon and tonight becoming mostly south and building during the
day on sat. With the better onshore flow better low level moisture
is expected to advect inland overnight through Sat afternoon
possibly leading to some patchy for most inland areas mostly before
sunrise Sat morning. With better mixing expected tonight the threat
for dense fog is lower compared to last night.

Temperatures will be generally 5 to 10 degrees warmer than last
night ranging from the low to mid 50s to the east and north and the
upper 50s to lower 60s to the west and along the immediate coast.

Highs Sat will range from the mid to upper 70s for most areas.

32 ee
short term Saturday night through Monday night ... A cold front
moves through the area Saturday night, with showers along and
ahead of the front ending from northwest to southeast by early
Sunday morning. Low temps Saturday night range from low 40's
inland to mid 50's along the immediate coast. In the wake of this
front, northerly winds usher in a cooler and drier airmass, with
afternoon highs Sunday only reaching the upper 50's to low 60's.

Expect colder lows Sunday night as clear skies and light winds
will allow plenty of radiational cooling, with temps dropping into
the low to mid 30's across much of the area. Some inland locations
could see temps dip just below freezing around sunrise early
Monday morning. Highs on Monday once again range from upper 50's
to low 60's, before lows in the upper 30's to mid 40's Monday
night as light surface winds shift to more easterly and a weak
upper shortwave bring an increase in cloud cover. 49
long term Tuesday through Friday ... Rain chances increase once
again Tuesday as a vigorous upper shortwave digs into the lower
mississippi river valley and northwestern gulf of mexico. At this
point, the upper level jet splits, with the southern stream trough
developing a surface low over the central gulf while the northern
stream remains over the midwest and great lakes. Models are
in fair agreement with another shortwave embedded within the
northern stream pushing a front through our local area Tuesday
night. This front eventually stalls well offshore and acts as a
sort of barrier, keeping the low out over the central gulf.

Heading through midweek, yet another impulse in the northern
stream digs across the eastern conus, this time falling into phase
with the southern stream trough. The resulting deeper longwave
pattern then pushes the central gulf low east towards the florida
peninsula and away from the local area.

Ultimately, the weather along our portion of the gulf coast will
depend on the track of the upper trough (and subsequent surface
low) over the gulf. Current model trends have it far enough south
for the bulk of precipitation to remain offshore. As the low
tracks east-northeast across the gulf, cloud cover and rain
chances would increase along and east of i-65 Thursday and
Friday, with areas west seeing fewer clouds and drier weather.

In terms of temperature, expect temps around seasonal on Tuesday,
with highs in the upper 60's to around 70 Tuesday afternoon and
lows in the mid 40's to low 50's Tuesday night. In the wake of
Tuesday night's front, temps drop a few degrees below-seasonal
Wednesday through Friday. Highs range from low to mid 60's, and
lows range from low to mid 40's. 49
marine... High pressure will continue to shift east to the eastern
seaboard and western atlantic through Sat in response to a strong
cold front approaching from the west. The cold front will move
across the marine area late Sat night through Sun morning leading to
a strong offshore flow, occurring throughout most of the day on
Sunday. Frequent gusts to gale force, occurring mostly over the open
gulf waters, will also be possible in the wake of the front early
Sunday. A moderate south to southwest flow is also expected ahead of
the front by mid to late Sat afternoon. Northerly winds and seas
will gradually subside Sun night through early Mon as a broad
surface ridge of high pressure builds from the lower mississippi
river valley to the southeast states through Mon afternoon. A light
onshore flow is expected by late Mon shifting mostly north to
northeast Tue through Thu in response to another cold front moving
south over the northern and central gulf. An area of low pressure is
expected to form along the front over the gulf moving mostly east of
the marine area Thu through sat. 32 ee
