Area Forecast Discussion
National Weather Service Shreveport LA
1204 PM CST Fri Jan 14 2022

.AVIATION...

For the ArkLaTex terminals, VFR until predawn w/ our next fropa
now in the OK/TX panhandles. SE 5-10KT under cirrus for now with
MVFR cigs and shwrs ahead of the front. Winds will swing NW before
daybreak for KTYR 09Z and for KTXK/KSHV/KGGG/KLFK at around 12Z
and late this period for both KELD/KMLU. NW winds 15-25G30-40KT,
cigs become VFR but wrap around moisture arriving on the backside
of the deep upper low over NE TX. RA to SN will be the dominant wx
unfolding as the cold core low arrives ovhd w/ 1" amounts. /24/

&&

.PREV DISCUSSION... /issued 1013 AM CST Fri Jan 14 2022/

SHORT TERM.../Today/

Top of the hour readings are climbing through the 50s areawide
with southeast winds picking up a bit last hour. Skies will remain
partly to mostly cloudy with mostly high clouds today. Our
diurnal run is unfolding as expected with no need for changes as
our highs will end up ranging from mid 60s to lower 70s. /24/

PREV DISCUSSION... /issued 400 AM CST Fri Jan 14 2022/

SHORT TERM.../Today through Saturday/

Significant weather changes are in store over the next 24-36 hours
with one more warm day to enjoy before we return to winter reality
for the weekend. Signals of this major pattern shift are already
well noted on water vapor imagery as the potent shortwave trough
continues to dive southeastward across the Intermountain West. In
advance of this shortwave, abundant cirrus is seen spilling south
across our region in the NW flow aloft and expect this to continue
throughout today with filtered sunshine and high temperatures very
similar to yesterday's readings but perhaps a few degrees lower
due to the added high clouds, likely becoming more dense across
our northern zones. As a result, expect highs in the mid to upper
60s over most of our northern zones compared to lower and mid 70s
farther south with sfc winds veering more S/SE throughout the day.

Moving into tonight, cloud cover will continue to thicken up as
we begin to saturate from the top down with increasing moisture
advection ahead of the incoming trough and cold front. As this
occurs, expect enough lift to induce some scattered showers over
our northern zones after midnight through daybreak on Saturday.
By this time early Saturday morning, the cold front will begin
rapidly entering our W/NW zones with strong cold air advection,
possibly allowing for a gradual transition to a mix of rain/snow
generally along and north of the Interstate 30 corridor where
temperatures will be falling into the mid to upper 30s. If this
does occur, no impacts are anticipated as soil temperatures will
still be relatively warm given our late week warming trend prior
to the cold front arriving. As the front continues its eastward
progression across the remainder of the region through Saturday,
expect falling temperatures with highs likely occurring during
the morning hours over the majority of the region.

The other notable mention with this cold front will be the very
strong NW winds behind it, likely warranting a wind advisory over
at least our western 1/3 and possibly western half of the region.
This decision will come with future forecast issuances so suffice
it to say wind chills will make it feel even colder on Saturday
following fropa. /19/

LONG TERM.../Saturday Night through Thursday Night/

A cold core closed low remains progged to shift SE through the
region Saturday evening, which will help deepen the colder post-
frontal air mass in wake of the cold fropa earlier in the day. While
a deep wedge of mid and upper level drier air will undercut the low
behind the front Saturday afternoon, increasing ascent between the
H250-700 low over SE OK/SW AR during the evening will result in
areas of precipitation that will slide SE across portions of extreme
Ern TX and N LA by mid to late evening, before subsidence increases
late on the backside of the low as it begins to exit the region to
the E into Wrn and Cntrl MS. While partial thicknesses suggest a
quick changeover from -RA to -SN during the evening, forecast
soundings suggest that the transition from -RA to -SN will be slower
to occur, given the fact that cold air damming from the Ouachitas
may be an issue, resulting in a more subtle lowering of the freezing
levels from NW to SE. There also remains some model discrepancies
with how fast sfc temps will fall during the late afternoon and
evening Saturday given the effect of the damming, with the GFS/ECMWF
a bit warmer in maintaining above freezing temps across much of E
TX/SW AR through the evening before falling to near freezing late.
Meanwhile, the HRRR and NAM are much colder with the subfreezing
air, bringing the freezing temps to the I-20 corridor of E TX and N
of I-30 across SW AR by 00Z Sunday. Thus, these models have a much
faster changeover to -SN late Saturday afternoon and early evening,
but does seem a bit too fast given the damming that is expected.

Did maintain chance pops during the evening over SW AR/NW LA with a
-RA/-SN mix, before gradually transitioning the precip over to all
-SN over SE OK/Nrn sections of SW AR prior to 06Z, with a mix
persisting over far Srn AR/N LA. Believe the freezing levels should
lower enough for any remaining wrap-around precip to be mostly -SN
after 06Z across Srn Ar/N LA, although this will be quickly ending
from W to E overnight with the departure of the low. As for snow
accumulations, with sfc temps remaining above freezing for much of
the evening across portions of Srn AR/N LA atop the already warm
ground temps, accumulations will be minimal with amounts varying
from a dusting to up to half inch, with the greater accumulations
mainly on grassy surfaces across Nrn McCurtain County OK and the Nrn
sections of SW AR. Not expecting any accumulations across N LA
(except for possibly a dusting at best near the AR border) as temps
should remain above freezing for the duration of the event.

The wrap-around stratocu shield should quickly diminish from NW to
SE through midday Sunday with the departure of the low, with NW
winds beginning to relax some as sfc ridging builds E into the
region. Below normal temps will persist though even with insolation
Sunday, with temps falling back to or below freezing areawide Sunday
night. A warming trend will commence Monday as temps return back to
near the daily norms, before increasing in earnest Tuesday as a Srly
low level flow increases on the backside of the departing sfc ridge
to the E, and with a tightening pressure gradient ahead of
developing cold front off to our NW from the TX High Plains NW into
NW OK/Srn and Ern KS. A SWrly LLJ is progged to develop Tuesday
afternoon and night, although low level moisture return will remain
limited as these LLJ winds quickly veer more W over NCntrl TX/LA by
daybreak Wednesday. Have maintained a dry forecast through Tuesday
night, before introducing slight chance/low chance pops Wednesday
for SW AR/N LA/extreme Ern TX as enough moisture pooling may exist
ahead of a subtle shortwave that will translate E across the Srn
Plains into the MS Valley. A digging longwave trough to the N over
the Upper Midwest/MS Valley should also drive this cold front
farther S trough the region Wednesday, reinforcing a colder and
drier air mass back S into the area. Did maintain some slight
chance/low chance pops even through Wednesday night with the fropa,
with the vast majority of the medium range progs suggesting dry
conditions through the remainder of the work week and at least the
first half of next weekend. Have dropped the slight chance pops the
NBM is advertising for Thursday/Thursday night given the little
model support, with below normal temps again returning to end the
long term period. /15/
