18z issuance...VFR conditions will prevail along the north central
gulf coast region this afternoon and through much of the evening
with only high level clouds increasing through the period.

Increasing low level moisture will move north from the gulf of
mexico and over the TAF sites beginning late this evening, with
ceilings expected to be in the ifr category (~700 feet).

Visibilities will also be reduced overnight due to developing fog,
possibly reaching the lifr to ifr categories (1 2sm to 1sm) late
tonight into Monday morning. Southeast winds 7 to 12 knots this
afternoon will lower to between 5 to 7 knots overnight. Expect
light rain to move into the mobile metro area after mid morning
Monday, so added a prob30 group for now. 22

Aviation...

21 12z issuance... GeneralVFR conditions through this evening
(around 22 03z), when ifr to lifr CIGS (low status) and
visibilities (fog) develop. Surface winds becoming southeast
around 10 knots today and continuing through tonight. 12 ds
prev discussion... Issued 426 am cst Sun jan 21 2018
near term now through Sunday night ... The upper shortwave noted
yesterday has now moved east of the forecast area, now over northern
florida, and will move off the atlantic coast today. As the upper
low moves off to the east, upper ridging will drift east across the
forecast area today. Tonight, the upper ridging is expected to move
quickly off to the east of the forecast area as deep low pressure
and troughing develops over the plains states. Surface high pressure
located along the southeast atlantic coast early this morning will
move out over the atlantic through tonight, while a cold front
associated with the developing plains system approaches from the
west. This cold front will be approaching the mississippi river by
daybreak Monday, with perhaps a few showers moving into our far
western counties very late tonight as the front approaches and upper
ridging weakens. Persistent low level southeasterly flow today and
tonight will bring increasing moisture into the region, and this
onshore flow combined with the cool near shore marine waters will
likely result in some fog across the area tonight, especially over
the southern locations near the coast. High temperatures today
finally return to the lower 70s for most locations, except along the
immediate coastal areas where the onshore flow will keep highs in
the mid to upper 60s. Warmer tonight too, with lows ranging from the
upper 40s over northeastern counties to the low to mid 50s
elsewhere. A few upper 50s possible along the immediate coast.

12 ds
short term Monday through Tuesday night ... Monday through Monday
night, a closed upper system moves from over the central plains
east-northeast over the mid upper mississippi river valley before
getting a more northeast push due to a building upper ridge over
the western atlantic. This system pushes a surface front across
southeast mississippi late Monday afternoon, then east of central
alabama and the western florida panhandle shortly after midnight
Monday night. Shra tsra pretty much a given ahead of the front
Monday afternoon into the evening hours. Biggest question is the
chance of any severe. Guidance remains on the marginal side for
any strong to severe (topping out around 500 j kg). 0-3km shear is
enough (200-300 m^2 s^2 in the afternoon) for some rotators.

Mid upper level support has shifted north a bit, north of the
forecast area in our case. SPC continues to advertise a marginal
risk of severe weather with damaging winds the primary threat and
see no reason to alter this at this point, with less overlap of
surface and upper ingredients than yesterday. Temps above seasonal
expected Monday. With cooler air moving over the area behind the
front, Monday night's lows will see a gradient of around seasonal
lows west to above east.

Tuesday through Tuesday night will see a return of near seasonal
temps as cooler drier air overspreads the entire forecast area.

16
long term Wednesday through Saturday ... Shortwave energy moves
over the plains mid week into the weekend, pushing surface high
pressure from the plains to off the mid atlantic coast. This
brings back southerly flow off the gulf by Friday. Moisture
levels increase into the weekend until another front moves across
the area Saturday night. Rain returns Friday night, with a better
chance of rain Saturday. Temps moderate slowly upwards from around
seasonal mid week to above seasonal with the return of southerly
flow end of the week.

16
marine... For the most part, no hazards in the near term except for
winds nearing exercise caution levels for the offshore gulf zones
this afternoon. A cold front approaches the marine area from the
west tonight and early Monday bringing an increased chance of
showers and embedded storms, as well as an continued increase in
seas associated with the increased onshore flow. The front is
expected to move east across the marine area Monday night. Showers
and storms ending with the frontal passage and a moderate to strong
offshore flow is expected in the wake of the front Tuesday through
late week. Winds and seas primarily in the exercise caution category
( 15 to 20 knots and up to 6 feet)through most of the week for the
offshore gulf waters, but possibly reaching small craft advisory
levels (20 knots plus) by weeks end as a reinforcing surge of
offshore flow develops. 12 ds

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
