National Weather Service Morristown TN
318 AM EST Wed Feb 8 2023
...New SHORT TERM, LONG TERM...
.SHORT TERM...
(Today through Thursday)
Issued at 316 AM EST Wed Feb 8 2023
Key Messages:
1. High winds expected in the Smokies tomorrow. Windy conditions
expected elsewhere in the east TN mountains, plateau counties, and
higher elevations of southwest Virginia.
Discussion:
A cutoff low over eastern New Mexico and the Texas panhandle this
morning, will open up and move east northeast into the Ozarks this
evening and overnight as a kicker shortwave moves into the Rockies.
In response to this, strong cyclogenesis will occur across the
Arklatex this evening and moving northeast into central Illinois
during the overnight hours. All of this will result in a cold front
moving east through Tennessee after midnight tonight, arriving in
our forecast area by mid morning tomorrow and pushing east of the
Appalachians by the end of the short term period.
Isentropic ascent and a swath of higher PWATs is resulting in some
isolated to scattered showers across northern Alabama. This will
shift north through the CWA this morning but am not expecting much
more than a couple hundredths through mid morning, mainly in the
southern valley and plateau areas. Most guidance shows rain chances
fizzling out by midday. Otherwise, expect today to be dry and on the
warm side once again. Warmest areas will likely be along/east of the
I-75 and I-81 corridor where increasingly backed H85 flow will
likely contribute to some weak downslope flow and subsequent warming.
For tonight, all guidance is insistent on a rapid strengthening of
the low level wind field, with a broad area of +60-70kt H85 winds
across western TN by shortly after midnight tonight as the low level
jet ramps up. With the surface low lifting northward into Illinois
by daybreak tomorrow morning, the stronger parts of the LLJ will
stay just to our northwest. However, there is plenty of evidence to
suggest that we will see high winds in the Smokies late tonight into
Thursday. Additionally, it is likely we'll hit wind advisory
criteria in the plateau, the rest of the east TN mountains, and also
the higher elevations of southwest Virginia. Would not be surprised
to see some 70mph gusts at Cove Mountain, with some 50-60mph winds
at Camp Creek area. Have gone ahead and hoisted up a high wind
warning and a wind advisory to cover this.
As far as rain chance go in the short term, after this weak area of
showers dissipates this morning dry conditions are expected until
after midnight tonight. By 09z-12z or so, an area of convection
ahead of the front should be pushing east into the forecast area.
With the upper low rapidly pulling away to the north, expect that
coverage and intensity of these showers will be waning as the push
into the CWA from the west. Have very high rain chances tomorrow but
rainfall amounts will be light. This will be especially true in the
northeast where persistent downslope flow will really eat away at
rain amounts.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 316 AM EST Wed Feb 8 2023
Key Messages:
1. Other than a few showers, most places will be dry Thursday night
through Friday, followed by a cooling trend.
2. A system will bring rain and snow to the Southern Appalachian to
Mid Atlantic regions Saturday through Sunday with limited confidence
on the extent of impacts in our forecast area. In any case, the best
chances for accumulating snow are in the Tennessee mountains and
higher elevations of southwest Virginia.
3. A warming trend will follow with rain chances returning by
Tuesday.
Thursday Night through Sunday
At the start of the period, a broad southwesterly flow pattern will
be in place aloft with the jet stream extending from the area up to
the northeast and troughing in the central U.S. A frontal boundary
will have passed through the area with slightly cooler and drier
conditions to begin the period. Heading into Friday, a secondary,
more notable front will move through the area as high pressure
expands from the west, ushering in cold air. This will also come the
advancement of a shortwave expected to become cut off from the large-
scale flow. Previously, this upcoming weekend had looked more like a
high elevation northwest flow set up, following CAA. However, the
closed low is indicated to become negatively tilted as it moves off
to the east with strong cyclogenesis expected to take place to the
south and east of our region Saturday into Sunday.
At this time, a lot of unknowns remain regarding the general
evolution and track of this next system. By most ensemble and
deterministic accounts, the thermal profile in the lower levels will
be sufficiently cold enough for precipitation to be predominantly
frozen in nature, possibly even outside of the higher elevations.
This of course is dependent on the aforementioned unknowns, which
are suggested to varying degrees within the global deterministic
model sources. The latest GEFS members, however, still illustrate
the wide range of solutions locally, from limited high elevation
snowfall up to more widespread, impactful accumulations. With all of
these factors in mind, HWO wording will be kept similar with focus
on the uncertainty and better chances for accumulations being in the
Tennessee mountains and higher elevations of southwest Virginia.
Monday and Tuesday
Heading into early next week, brief high pressure and shortwave
ridging will lead to drier and milder conditions for Monday.
Afterwards, another shortwave will eject out of the Southern Plains
and advance towards the region, later becoming more negatively
tilted. At this time, the result looks to be a return of
precipitation in the form of all rain in our area. Based on the
consensus and synoptic pattern, convection is likely closer to the
Gulf Coast region at a minimum.

.AVIATION...
(06Z TAFS)
Issued at 1249 AM EST Wed Feb 8 2023
A small area of showers over central AL will move northeast
through the remainder of the night, arriving in the southern TN
valley around 10z-12z. They'll be fairly ISOLD in nature, so will
just go with VCSH and some SCT025 bases at KCHA for now. There's
indications this could shift to KTYS as well but given spotty
nature and lower confidence that far north, will leave out of
KTYS. No showers or lower ceilings expected at KTRI. Winds will be
light at all sites, but should see increasingly steady southerly
component to winds at KTYS and KCHA after daybreak.
