...WINTER WEATHER ADVISORY IN EFFECT FROM NOON TUESDAY TO 6 AM
CST WEDNESDAY...
...WIND CHILL ADVISORY IN EFFECT FROM MIDNIGHT TUESDAY NIGHT TO
10 AM CST WEDNESDAY...

* WHAT...Precipitation initially in the form of a wintry mix of
  light rain, sleet, and snow will gradually turn into light snow
  across the region late Tuesday afternoon into Tuesday night. 
  Snow accumulations are generally expected to be less than one 
  half inch, though isolated totals over one inch cannot be ruled 
  out. Elevated northerly winds will bring dangerous wind chills 
  in the single digits late Tuesday night into Wednesday morning. 

* WHERE...Across all of southeast Mississippi, and much of 
  southwest and south central Alabama and the northwest Florida 
  Panhandle away from the immediate coast. 

* WHEN...For the Winter Weather Advisory, from noon Tuesday to 6 
  AM CST Wednesday. For the Wind Chill Advisory, from midnight 
  Tuesday night to 10 AM CST Wednesday.

* ADDITIONAL DETAILS...Temperatures will fall well below freezing
  Tuesday night, so any lingering light snow accumulations on area
  roadways will cause slick travel conditions even after 
  precipitation ends. The cold wind chills will cause frostbite in
  as little as 30 minutes to exposed skin.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Weather Advisory for snow, means periods of snow will 
cause primarily travel difficulties. Be prepared for snow covered 
roads and limited visibilities, and use caution while driving.

A Wind Chill Advisory means that cold air and the wind will
combine to create low wind chills. Frost bite and hypothermia can
occur if precautions are not taken. Make sure you wear a hat and
gloves.

WEDNESDAY...
...WIND CHILL ADVISORY REMAINS IN EFFECT UNTIL 11 AM CST
WEDNESDAY...

* WHAT...Precipitation, mainly in the form of snow, will move east
  across the region through the early morning hours. Along the
  leading edge of the precipitation and down along the coast, a
  brief period of freezing rain and sleet is likely. Light
  accumulations, less than a tenth of an inch of freezing rain,
  and less than one half inch of sleet are expected. Snowfall
  accumulations of 1 to nearly 2 inches are possible over inland
  areas in association with the heavier snowbands. Since
  temperatures are already well below freezing across most of the
  area, hazardous driving conditions are becoming widespread
  across interior portions of southeast Mississippi due to
  accumulating snow and some icing. Conditions will very slowly
  improve through Noon tomorrow. Strong north winds will result in
  dangerous wind chill values in the single digits late tonight
  and early Wednesday morning. 

* WHERE...Areas south of the I-10 Corridor will experience a of
  freezing rain before changing over to sleet and snow overnight,
  whereas north of I-10 will be primarily snow. 

* WHEN...The wintry precipitation will continue across most 
  inland areas through 2 AM, then gradually end from west to east 
  through 6 AM. A Winter Weather Advisory is in effect until 6 AM 
  CST Wednesday. A Wind Chill Advisory is in effect from midnight 
  tonight to 11 AM CST Wednesday.

* ADDITIONAL DETAILS...Be prepared for hazardous conditions on
  area roadways, especially inland areas. Be prepared for reduced
  visibilities at times. The cold wind chills will cause 
  frostbite in as little as 30 minutes to exposed skin.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Weather Advisory means that periods of snow, sleet or
freezing rain will cause travel difficulties. Be prepared for
slippery roads and limited visibilities, and use caution while
driving. The latest road conditions for the state you are calling
from can be obtained by calling 5 1 1.

A Wind Chill Advisory means that cold air and the wind will
combine to create low wind chills. Frost bite and hypothermia can
occur if precautions are not taken. Make sure you wear a hat and
gloves.

The local office's own words before this wind chill advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Mobile, AL wrote its last area forecast discussion before this wind chill advisory went out at Jan 15, 11:26 AM CST, 3 hours 23 minutes earlier.

AVIATION...
12Z issuance...VFR conditions and light easterly winds expected
through the period. /49

PREV DISCUSSION... /issued 408 AM CST Mon Jan 15 2018/

NEAR TERM /Now Through Monday night/...Upper-level flow becomes
more zonal over the local area through the near term as a
shortwave exits to our east and another, more substantial trough
digs into the Plains to our west. At the surface, high pressure
builds over the eastern seaboard and southeastern U.S., which
results in a more easterly flow across our local area. With cold
air advection coming to an end, we see a warming trend in
temperatures today (mid 50s areawide) and tonight (low to mid
30s), while the weather remains clear and dry. /49

SHORT TERM /Tuesday Through Wednesday night/...An arctic cold
front located at the northwestern edge of the forecast area early
Tuesday morning moves through the remainder of the area during the
day and ushers much colder air into the region. There remains the
potential for patches of precipitation to occur in the wake of
the frontal passage, mostly in the form of a wintry mix, beginning
first over interior southeast Mississippi and interior southwest
Alabama then shifting eastward across the remainder of the area
overnight. Model soundings indicate that the duration of the
precipitation will probably be about 3 hours for most areas before
drier air aloft shuts off the precipitation. While no
accumulation of wintry precipitation is expected, a light dusting
of snow cannot be ruled out over interior areas.

Overnight lows trend colder Tuesday night into Wednesday night
with lows Tuesday night ranging from the upper teens well inland
to the upper 20s at the coast, then Wednesday night will see mid
teens well inland ranging to mid 20s at the coast. Highs on
Wednesday will be unusually cold and expected to only reach the
mid to upper 30s for most areas, which is about 20 to 25 degrees
below seasonable values. A Hard Freeze Watch has been issued for
late Tuesday night into early Wednesday morning roughly along and
west of I-65. Another Hard Freeze Watch will likely be required
for all areas north of the coast Wednesday night into early
Thursday morning. In addition, late Tuesday night into early
Wednesday morning will have northerly winds near 10 mph combined
with the very cold temperatures. This results in wind chill values
of 5 to 10 over interior areas and a Wind Chill Advisory will
likely become necessary for this portion. /29

LONG TERM /Thursday Through Sunday/...A shortwave trof advances
across the central states on Thursday then splits on Friday with
the northern portion continuing across the interior eastern states
and the southern portion lingers over eastern Texas. The latter
feature finally ejects eastward across the Gulf coast states
Saturday into Saturday night while a larger upper trof advances
across the western states into the central states. A dome of
surface high pressure over the forecast area on Thursday gradually
retreats into the western Atlantic through Saturday night while a
surface low (associated with the advancing upper trof) develops
over the central Plains. The surface low moves off towards the
Great Lakes region on Sunday and brings a trailing cold front to
near the lower Mississippi river valley. Despite the passage of
the shortwave trof over the area Saturday into Saturday night, no
precipitation is expected at this time as isentropic lift looks
too weak over the forecast area. Slight chance to chance pops will
return to the forecast on Sunday with the approach of the cold
front and increasing isentropic lift. Lows Thursday night look to
remain above hard freeze warning criteria and range from the mid
20s inland to the lower 30s at the coast. A warming trend follows
with seasonable to slightly above seasonable temperatures
expected by the weekend. /29

MARINE...High surface pressure over the southeastern U.S. results in
a generally light east to northeast wind flow over the marine area
into Tuesday. A strong frontal passage then brings increasing
offshore flow and building seas Tuesday night through Wednesday
night, along with a slight chance of showers and more bitter cold
temperatures. A Small Craft Advisory will likely be required during
that period, before winds begin to subside and shift to more
easterly once again Thursday. With high pressure building over the
eastern Gulf on Friday, light to moderate onshore flow sets back up
over the weekend ahead of the next approaching system. /49
