Area Forecast Discussion
National Weather Service Jackson MS
557 AM CST Fri Jan 6 2017

...WINTRY WEATHER EXPECTED TODAY...

.UPDATE...
Updated for 12Z aviation discussion

&&

.AVIATION...
12Z TAF discussion:
The bottom line is this will be a bad day for aviation. Precipitationis
moving in from the west this morning and will eventually transition
over to sleet or freezing rain for locations along and south of the
I-20 corridor through the morning and definitely into the afternoon.
Further north, precipitation that occurs should be more in the form
of snow that would affect GLH/GWO/GTR but this may not be til later
this afternoon. HBG should remain as rain for a while into the
afternoon before transitioning to sleet or some freezing rain. Winds
will be out of the north and gusty at times. /28/

&&

.DISCUSSION...

Today and tonight...

Very complicated forecast this morning as we are on the doorstep of
our first decent winter weather event this year. Cold air is already
in place over the region thanks to the reinforcing cold front from
the other day. Locations north of I-20 are below freezing whereas
the remainder of the area is above freezing, with low 40s in the
Pine Belt. Some very light rain or drizzle is ongoing this morning.

Overall the thinking hasn't changed in terms of the overall setup
for this incoming wintry precipitation event. A mid-level trough will
continue to develop across the Texas Panhandle through today and
swing east. As this occurs, a sfc low will further develop and track
northeast off the Texas coast. As this occurs, precipitation will
overspread the region. Models continue to paint two main areas of
precipitation. The first is a swath of snow just to the north of my
CWA. The HRRR indicates some of this precipitation occurring further
south across portions of my northern counties/around the Highway 82
corridor. If this does occur, there could be some light snow in
these locations during the morning hours. This wave will pass and
there could be a lull in precipitation across northern counties this
afternoon.

To the south, precipitation will likely be light rain at first
before the transition to sleet/freezing rain occurs this afternoon.
Model soundings continue to show a rather deep warm layer across
much of the central and southern parts of the ArkLaMiss region
through the morning and afternoon, once surface temperatures are
able to cool closer to freezing. This will bring some sleet to the
area but more likely freezing rain. Further south across the Pine
Belt, surface temperatures should remain warm enough for
precipitation to remain rain through much of the afternoon. There is
enough instability to where that area could even see some thunder.
As evaporative cooling occurs,freezing rain and sleet should move
into the Pine Belt later this afternoon and likely become the more
predominant precip type.

Models this morning continue to waffle both in amount of QPF and how
far north this occurs. Ultimately, the strength of the incoming
upper trough will dictate how far north this precipitation, and thus
type of precipitation, will be. For now, have left snow/sleet
accumulations in the advisory range and below winter storm warning.
Ice accumulations should also remain below one quarter of an inch.
However, this will be something to monitor in terms of how things
trend today. If precipitation is heavier or farther north,
accumulations could be higher and cause more of an impact across the
central and southern areas. If things continue to trend colder and
heavier precip, more effective evaporative cooling could occur and
lead to higher snow totals. Will include an elevated threat in the
HWO/graphics for the area between the Jackson metro and the Pine
Belt as current model guidance shows this could be the best area for
accumulations.

The upper trough will swing across the area later this evening.
Models indicate another band of snow associated with this which
could impact north MS/the Highway 82 corridor as well. Due to the
morning snow potential and this evening potential, have included the
remainder of my CWA in the Winter Weather Advisory with snow
potential of generally half an inch but perhaps some places could
see totals up to an inch. The trough will swing through this
evening. As this occurs, soundings indicate that all locations will
have cooled enough for light snow to occur before moving out prior
to midnight.

As if the winter precipitation wasn't enough to think about, cold
air will move in behind this system. Some of the coldest air of the
season, and certainly for this year, will occur tonight and through
the weekend. Highs today will be in the 30s, but likely with
precipitation occurring, readings will mostly be in the 20s and
lower 30s. Overnight lows tonight will drop to 20 degrees or below.
The coldest readings will be across the HIghway 82 corridor, with
temperatures in the upper teens. Temperatures won't rebound much on
Saturday. This, coupled with a gusty north wind, will bring very
cold wind chills to the region. Single digit wind chills will also
be possible across the Highway 82 corridor, even possibly as far
south as the I-20 corridor. Will include a limited risk in the
graphics/HWO for this hard freeze and wind chill danger risk. Future
shifts will likely need to issue a Hard Freeze Warning and Wind
Chill Advisory. /28/

Saturday through Thursday night... Strong high
pressure and drier air will move in on Saturday and with strong cold
air advection, highs will only climb into the low 30s for much of
the area. Hard freeze warnings will likely be needed for the
northern portions of the area Saturday and Saturday night, with lows
falling into the teens for much of the area. High pressure will
continue on Sunday with slightly warmer highs in the 40s. The
surface high will shift east of the area by Monday and the flow will
swing around to the southeast. This will be the beginning of a
warming trend early next week with high temperatures climbing into
the upper 60s/low 70s by Tuesday.

A relatively weak cold front will drop across the area Tuesday night
into Wednesday with an increased chance for showers and
thunderstorms. The boundary will quickly turn around and move back
north on Wednesday with a continued chance for showers and
thunderstorms. Thursday will be another unseasonably warm day with a
continued chance for showers and high in the 70s./15/
