Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
1220 PM CST Mon Jan 28 2019

.DISCUSSION...See updated information below.

&&

.UPDATE...Current forecast looks good. Could see a few minor
tweaks this evening maybe for tonights precip but nothing
significant attm. Stay tuned. Did bring the winds up significantly
for tonight and on Tues due to the strong push of cold air in the
wake of the front. Right now not seeing wind advisory criteria
though we may get very close to these conditions mostly over the
coastal counties of both AL and NWFL during the day on Tue. 32/ee

&&

.MARINE...Have made a few tweaks to the earlier forecast mainly
to bring winds up over inland bays and sounds. As a result a
Small Craft Advisory will be in effect for the entire marine area
including all inland bays and sounds from 3 am CST through 6 pm
CST on Tue and the open gulf waters out to 60 nm including lower
Mobile Bay and MS Sound through Tues midnight. 32/ee

&&

.AVIATION...
18Z issuance...VFR conditions through about 29.06z followed by
mostly MVFR cigs through 29.18z. Lower cigs mostly in low stratus
and light rain in the wake of a strong cold front that moves
across the region after midnight tonight. Winds will be south to
southwest at 8 to 12 knots through about 29.09z followed by a
strong west to northwest flow at 15 to 25 knots with higher gusts
through about 29.15z then north through 29.18z. 32/ee

&&

.PREV DISCUSSION... /issued 632 AM CST Mon Jan 28 2019/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
28/12Z issuance...VFR and light winds of 10 knots or less expected
across the region today into the early evening hours. Ceilings
develop and lower this afternoon and tonight, but generally
remain VFR. Precipitation develops overnight, especially after
midnight as a cold front approaches from the west. Over
northwestern portions of the forecast area rain will change to
snow as we approach sunrise Tuesday morning. 12/DS

PREV DISCUSSION... /issued 456 AM CST Mon Jan 28 2019/

NEAR TERM /Now Through Monday night/...High pressure just to the
east of the forecast area this morning will weaken and get pushed
further to the east through this evening as a strong cold front
moves rapidly toward the forecast area from the west. Mostly clear
skies this morning but increasing clouds expected through this
evening as the front approaches. Highs today generally in the lower
60s.

Increasing southwesterly flow today and this evening in advance
of the approaching front, shifting to the northwest and becoming
stronger after midnight in the wake of the front as it moves east
across the area.

No precipitation today, but rain will develop and begin to move into
the area from the west around midnight tonight as the front
approaches. The front will move east across the entire forecast
area between midnight and 6 AM Tuesday morning with much colder
air quickly spilling into the region in its wake. An upper
shortwave in the base of a broad upper trof will rotate toward the
area late tonight and associated large scale ascent will result
in continued light to moderate precipitation behind the front. In
the wake of the front, rain transitions to a rain/snow mix after
about about 3 AM Tuesday and then to all snow as cold air makes
its way into the area toward daybreak. At this time, snow could
begin accumulating along and north of a general Beaumont MS to
Camden AL line before daybreak, with up to near one half of an
inch possible in some parts of Wayne and Choctaw counties.
Additional accumulations will be possible after 6 AM Tuesday and
are further discussed in the short term discussion below. Some
slick spots on roads, especially bridges and overpasses are
possible before daybreak (and more likely for a few hours after
sunrise Tuesday), mainly over parts of Choctaw and Wayne counties.
Snow will then spread east after sunrise, and again impacts,
locations and accumulations for this is discussed in the short
term discussion which follows. We have now issued a Winter Weather
Advisory beginning at 3 AM Tuesday morning for portions of
interior southeast MS and interior southwest AL, roughly for
counties along and north of the aforementioned Beaumont-Camden
line. Locations farther south and east will likewise see a
transition to rain/snow mix after daybreak Tuesday. Turning much
colder with the frontal passage, with lows tonight ranging from
the lower 30s far northwestern zones to the lower/mid 40s far
southeastern and coastal zones. 12/DS

SHORT TERM /Tuesday Through Wednesday night/...With arctic cold
front making passage Tuesday, strong cold air advection in its
wake and a drop in temperatures occurs thru the day. Post frontal
precipitation falling in the deepening colder thermal profiles
supports snow over the interior Tuesday morning. Latest WPC
probabilities for measurable snow indicate a 10-20% line extending
from Perry Co. MS to central Butler Co. AL. The probabilities for
snow amounts approaching around 1" increase northward from there,
with the higher probability (40 to 60%) over Choctaw Co. AL.
Latest gridded snowfall totals ending by noon Tuesday range from a
half to near 1.5 inches along and northwest of a line from
Runnelstown MS to Thomasville, AL. Southeast of this line to
southern Perry Co. MS to Monroeville AL to eastern Wilcox Co. AL,
a quarter to a half inch of snow accumulation is advertised. Winter
weather advisory for all areas mentioned continues to noon Tue
and headlines will be posted on the 4 AM package. Main impacts
will be to driving as some slick spots on bridges and overpasses
become likely.

Just to the south and east of the winter weather advisory, snow
flurries are quite possible from the remainder of the southeast MS
zones to central/northern portions of Mobile/Baldwin Co's
northeast from there to along the I-65 corridor also thru noon.
Forecasters expect no accumulation at this time of snow in these
areas.

Dry air quickly spreads in from west to east with precipitation
ending by Tuesday afternoon. Northwest flow increases Tuesday and
could increase to wind advisory criteria over the coastal zones.
Later shifts will monitor for this potential. There are
indications that high level clouds will be increasing from west to
east late Tuesday night, which could have an impact on how cold it
gets. For now, will maintain lows in the lower 20s over the
interior. 29 to 32 along the coast.

A chilly day on tap Wednesday. With the consideration of thickening
high based cloud cover Wednesday, forecasters favor a lower
adjustment to daytime highs which look to stay in the 40s area-
wide. Wednesday night cold. /10

LONG TERM /Thursday Through Sunday/...Surface high pressure
gradually moves east of the area during the longer term resulting
in a gradual modification in daytime highs/night-time lows to
close out the week. Daytime highs recover back into the 60s over
the weekend with a small chance of showers. /10

MARINE...High pressure continues to prevail over the marine area
through today but gradually weakens this evening as a strong cold
front approaches from the west. This front is expected to move east
across the marine area after midnight tonight with a strong
offshore flow and building seas developing in its wake. We have
gone ahead and issued a Small Craft Advisory for all Gulf waters
and the Mississippi Sound and southern Mobile Bay beginning 3 AM
Tuesday and continuing through 9 PM Wednesday, with Exercise Caution
elsewhere. Winds and seas will be subsiding on Wednesday, gradually
falling below SCA criteria late. A light to moderate mainly easterly
flow is then expected late in the week. 12/DS
