Area Forecast Discussion
National Weather Service Nashville TN
527 PM CST Wed Jan 5 2022

.UPDATE...
FOR 00Z AVIATION DISCUSSION.

&&

.DISCUSSION...

Today's temperatures have rebounded to slightly warmer than normal
levels, in the upper 40s and lower 50s with breezy winds. This is
occurring ahead of an initially dry frontal passage this
afternoon that will help set us up for wintry wx tomorrow. Lows
tonight are expected to drop into the 20s areawide.

By daybreak Thursday, a strong and intensifying H5 jet streak is
forecast to be racing from the Central Plains toward Tennessee. At
the same time, a surface low pressure area is expected to form
across southern MS that will track northeastward along the Arctic
front through central AL/GA into the Carolinas. Strong lift
associated with both features atop the Arctic airmass will create
widespread precipitation that will spread into Middle Tennessee
starting around 10Z Thursday, covering the whole area by midday
before quickly exiting during the afternoon as the surface low and
upper shortwave depart.

Forecast soundings from all available models continue to indicate
all snow throughout the event along and north of I-40. South of
I-40 and especially in the counties near the Alabama border, some
forecast soundings (NAM, HRRR, SREF) show a warm nose at the
onset of precip Thursday morning that will erode as precipitation
spreads and cold advection increases. We think the cold air will
win out with mostly low impacts from freezing rain and sleet.
However, these warm nose situations often complicate our winter
forecasts, so people in our southern counties should be prepared
for the potential of at least some glaze development. Because of
the mixed precip type, our southern counties should see the lowest
snow totals with around 1 to possibly 2 inches. Along and north
of I-40, we continue to forecast about 3 inches of snow. However,
12Z models have shown a substantial increase in qpf. This could
translate to snow amounts pushing over 4 to maybe 6 inches for
areas along and north of I-40 and this would require a Winter
Storm Warning. Our reason for keeping the advisory in place is the
sudden jump in model qpf. We would like to view updated model
information this evening to see consistency before pushing these
higher amounts. Since we are already pushing the upper bounds of
advisory criteria, it is quite possible our evening or overnight
crews may decide to issue a warning for parts of even much of our
area with higher snowfall totals if models maintain support for
it.

Once snow gets going, temperatures will stay below freezing
throughout the day on Thursday, with lows falling into the teens
and single digits by Friday morning. Whatever ice/snow that falls
will easily accumulate on roads and create hazardous travel
conditions as we go through the day on Thursday and especially
Thursday night into Friday morning.

Although some sunshine is expected Friday, temperatures will
struggle to climb beyond the 20s. lows Friday night will be very
cold again, in the teens. An upper level ridge will build up
quickly for Saturday with highs in the 40s. This is a little lower
than previous forecasts and guidance since we expect a good deal
of snow to be on the ground, holding back temp rises. The warm
advection will continue Saturday night into Sunday, but the
pattern will also bring moisture, meaning widespread rain
showers. Another front will swing across the area Sunday evening.
A brief flurry could occur as the cold front chases out the rain
showers, but no accumulating snow. After this system, a return to
cold, dry weather is expected for at least the first half of next
week.

&&

.AVIATION...
00Z TAF DISCUSSION.

Mostly clear skies will give way to a gradually lowering cloud
deck during the overnight hours, with borderline MVFR CIGS around
12Z. Light snow is expected to begin falling around this time, and
by 15Z-16Z all TAF sites will likely be impacted by IFR VIS and
CIGS as the snow intensity picks up. This should last for the
remainder of the TAF period, though possible amendments for LIFR
conditions may be possible with the heaviest snowfall.
