.UPDATE...
Issued at 418 AM CST Sat Jan 24 2026

Looking at radar, you might think it`s already starting to snow in
Middle TN, but the air is so dry it`s taking awhile for the
atmosphere to saturate. Obs sites in West TN are starting to show
light snow over the last hour or two, so it`s not far off. Latest
several runs of the HRRR have been very consistent showing light
to moderate snow will begin in the next few hours and stick with
us until mid-afternoon when the change to sleet will occur. This
should be maintained for a couple of hours for everybody until the
warm nose aloft pushes far enough northward to change everyone
over to freezing rain. I think the forecast is still fairly well
on track with snow/ice totals, so I won`t make any changes in
those categories, but now is the time where we`ll have to start
paying to attention to in-situ observations rather than relying
on models to ascertain where that warm nose is residing at any
given hour. This will help us track the progress of p-type
transitions throughout the day.

Folks, if you haven`t made any preparations to protect people,
pets and property yet, you might have a couple of hours after
sunrise, but the time is running very short. By early this
afternoon when we change from snow to sleet, the freezing rain
won`t be far behind and then it`s too late. While many along and
east of I-65 will change over to all rain late tonight, the damage
of heavy icing will already have occurred. This will be a
situation where you need to get where you`re going early and
expect to stay for awhile. Major travel impacts will be
widespread and there will likely be at least scattered if not
numerous areas without power for an extended period of time due to
the amount of ice that is expected to build up. This is
unfortunate because of the arctic air that will arrive tomorrow
night. Use caution out there and do what you can to stay warm!

.SHORT TERM...
(Tonight through Sunday Night)
Issued at 1050 PM CST Fri Jan 23 2026

No major changes to impacts or messaging are in this forecast
package. Ice and snow accumulation remain pretty consistent from
the previous couple of forecasts. We have the greatest confidence
in impactful ice accumulation across our southwest counties where
an Ice Storm Warning is in effect. Elsewhere, the Winter Storm
Warning remains in place for both accumulating snow and impactful
freezing rain. Greatest impacts continue to include hazardous
travel conditions across Middle TN, and significant risk of tree
damage and power outages, particularly from southwest Middle TN up
toward Nashville Metro.

This Friday night, precipitation continues to blossom across the
southern plains and Lower Ms Valley. The leading edge of this
precip will start to reach Middle TN near daybreak in the form of
mainly light snow mixed with some sleet. Snow mixed with sleet
will spread across the area through the morning hours. By
lunchtime, snow accumulation will reach around one inch for the
northwest counties with lower amounts elsewhere.

Through Saturday afternoon and evening, a "warm nose" will move
up from the south bringing a gradual south to north transition to
sleet, then freezing rain. It is during the evening hours we will
start to see the potential for significant accrual of ice,
especially on elevated surfaces like trees and power lines. Later
Saturday night, the warm nose will push farther into our eastern
counties pivoting the liquid/freezing line to a southwest to
northeast position across the area. The northwest side of this
line is where late night ice will build up with pockets of
damage possible. Southeast of this line, surface temperatures
will creep up above freezing bringing at least temporary
improvement to driving conditions and mitigating ice damage
potential. By daybreak Sunday this dividing line will run through
Nashville Metro southwest to Waynesboro. There could be
significant differences in ice totals across short distances along
this zone.

The surface low will lift to the northeast Sunday morning scouring
out the warm air wedge allowing for the precipitation to change back
to snow as low level winds turn back to the northwest. This final
coating of snow on Sunday may bring an inch or 2 of fresh snow
along and north of I-40 with lighter amounts to the south. By late
Sunday evening, travel will be hazardous area-wide with layers of
snow and ice. ALthough the Plateau region and far southeast will
be spared the worst of the ice and snow Saturday night and much of
Sunday, conditions in the areas will worsen Sunday night as
leftover moisture freezes with the surge of cold air following
the storm system.

Keep in mind, the end of the precipitation is not the end of the
weather risk. We continue to be concerned about frigid conditions,
potentially life threatening cold, that will follow this storm.
Temperatures Sunday night will plummet into the single digits and
teens with sub zero wind chills. Look for extreme cold headlines
and more focus on the bitter cold as we move past the worst part
of the winter storm.

.LONG TERM...
(Monday through next Saturday)
Issued at 1050 PM CST Fri Jan 23 2026

Models continue to show a persistent cold pattern next week with
a couple of reinforcing shots of brutally cold air. Forecasts
include some sub-zero readings Monday night and perhaps again
late in the week. Otherwise, lows will be mainly in the teens
through the week. These cold temperatures and episodes of very
low wind chill values will necessitate some extreme cold warnings.
People who lose power and heat will be in danger during this
period. Warming shelters will be needed and we all need to check
on our neighbors, especially our more vulnerable neighbors.
Daytime sunshine will be helpful with travel recovery next week,
but depending on accumulated snow and ice amounts, untreated back
roads could be a problem all week.

.AVIATION...
(12Z TAFS)
Issued at 418 AM CST Sat Jan 24 2026

Starting 15-17Z/Sat, flying conditions will become brutal as all
terminals experience snow, then sleet, then freezing rain. MVFR
should enter the picture over the next few hours, then cigs and
vis will become LIFR for all terminals around 01-03Z/Sun. Winds
will slowly start to relax throughout this cycle, remaining north
to northeasterly.
