And it is still snowing lightly. The coldest heavy snow in DFW recorded history. And the heaviest cold snow by a good margin. Also, the heaviest snowstorm since 2/2010.

Few people are as wrong as often as Clay Travis is so it sounds like the people of Nashville better get out the beach wear and sunscreen.
He wasn’t lying as it looked like shards of glass falling out of the sky about 30 minutes ago Here. Temps at 23.5 degrees. Going to be interesting to see if the snow is cut back here as much as models have shown tonight. I don’t think I have to worry about zr as much as just sleet.

NWS Storm Prediction Center Norman OK
0309 AM CST Mon Feb 15 2021

Areas affected...parts of southern LA...southern into eastern
MS...northwest AL

Concerning...Freezing rain

Valid 150909Z - 151515Z

SUMMARY...Freezing rain rates 0.05-0.20 inch per 3 hours are
possible through 9am CST.

DISCUSSION...Radar mosaic shows a relatively small precipitation
shield moving northeast from southeast LA towards southern MS as of
3am CST. Surface conditions show temperatures ranging from near
freezing in southern LA to the middle 20s over central MS. Baton
Rouge recently observed over a tenth of liquid-equivalent
precipitation in the past hour (09z observation).

Large-scale ascent, associated with the eastward-migrating shortwave
trough over the southern Great Plains, will steadily increase early
this morning across the lower MS Valley. The leading edge of
stronger ascent is already implied in water-vapor imagery with
convection over southwest LA. The 06z NAM model indicated 3-hourly
precipitation totals generally in the 0.05-0.15 inch range but had
locally higher amounts. Forecast soundings from southern LA
northeastward show a sub-freezing layer beneath a layer near 850 mb
around 5-8 C. The profile will support freezing rain as the primary
precipitation type early this morning. Sleet may intermittently mix
with freezing rain, especially in the northwest quarter of the
discussion area where the depth of cold air is more favorable for
sleet.

ICE STORM WARNING!1613384015024.pngtHIS IS VERY SERIOUS.
Ice Storm Warning
URGENT - WINTER WEATHER MESSAGE

Tuscumbia, Russellville, Red Bay, Moulton, Town Creek, Athens,
Huntsville, Decatur, and Cullman
402 AM CST Mon Feb 15 2021

...ICE STORM WARNING IN EFFECT UNTIL 6 AM CST TUESDAY...

* WHAT...Significant icing. Ice accumulations up to one half
inch. Snow and sleet accumulations of up to one inch.

* WHERE...Lauderdale, Colbert, Franklin AL, Lawrence, Limestone,
Madison, Morgan and Cullman counties.

* WHEN...Until 6 AM CST Tuesday.

* IMPACTS...Power outages and tree damage are likely due to the
ice. Travel could be nearly impossible, especially by late this
morning and through much of the day. These hazardous travels
conditions will impact the morning and evening commute.

* ADDITIONAL DETAILS...Power outages will be likely due to the
expected ice accumulations, which in some rural areas could last
for a few days. The combination of bitter cold temperatures
tonight into Tuesday will make conditions particularly
hazardous for those that do lose power. Residents should be
prepared and have an emergency supply kit ready in event of a
long duration power outage. Travel conditions will be very slow
to improve on Tuesday into Wednesday, even after the
precipitation ends.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Travel is strongly discouraged. If you must travel, keep an extra
flashlight, food and water in your vehicle in case of an
emergency. Prepare for possible power outages.
 
FIRST TIME EVER FOR ICE STORM WARNING FOR HUNTSVILLE COVERAGE AREA SINCE THIS HAZARD STARTED BEING USED

Based on wunderground reporting stations, it appears most people have warmed 1-3 degrees overnight across much of central and north AL. Need to get that cold air moving if this is going to happen. WAA is going to be roaring later on. I need Honda to close up shop for the day!
 
HSV AFD really hit the points this morning


1. An upgrade to an Ice Storm Warning was done across northwest and
much of north central Alabama. This replaces the Winter Storm
Warning. Significant ice accumulations and impacts will be felt in
these areas. Moreover, the predominant precipitation type in these
areas will be freezing rain (with sleet and/or light snow and rain
mixing in at times), depending on your location. Treacherous travel
conditions are expected in these areas with heavy icing leading to
some tree and power line damage.

2. A Winter Storm Warning remains in place for all of southern middle
Tennessee and northeast Alabama. Confidence is still high that
widespread, significant impacts due to ice, sleet, and light snow
accumulations will occur in those areas. However, they will be less
so than areas to the south and west and ice accumulations will be
less as well. Regardless, it is critical for folks in these areas to
take this warning seriously and be prepared for significant wintry
impacts.

3. The start time of the Winter Storm Warning for Marshall, Jackson,
and DeKalb counties was moved up to NOW. The reasoning behind this is
that light freezing/drizzle will be moving in early this morning.
Ridgetops could start to see icing impacts shortly, especially in
Marshall and Jackson Counties. It`s a much more a complex situation
here where valleys are a few degrees above freezing and ridge tops
are below freezing. However, all locations will see wintry impacts by
later today and especially this evening and tonight.

4. Temperatures will vary during the event, depending on your
location. In fact, a brief change over to rain isn`t out of the
question in areas along and east of Interstate 65. Models continue
to "tease" a warm up to at or above freezing in these areas. While a
warming trend is likely, the values advertised by the models for a
large chunk of the area are likely overdone (as they have been for
several days). Thus, we continue to have confidence that most areas
will see significant winter impacts during the warning window.

5. Freezing rain will begin to overspread most of the region from
the SW over the next couple of hours and impacts will be felt
immediately in areas that are below freezing. The aforementioned
locations in the Ice Storm Warning will be primed for significant
ice accumulations and subsequently bigger travel and societal
impacts. Expect and prepare for hazardous travel for your morning
commute.

6. Regardless of where you live, hazardous travel impacts could last
well into Tuesday and potentially through Wednesday morning (when we
finally could warm up above freezing). Bottom line: With temperatures
not forecast to rise above freezing in most areas on Tuesday,
persons could be stuck where they are for as much as 24-48 hours.

7. Bitter cold air will filter into the region behind the arctic
front tonight, with temperatures dropping into the Teens late tonight
and Wind Chills in the single digits to near zero degrees in some
places. A Wind Chill Advisory may be needed in later forecast
updates.

8. Depending on the magnitude of ice accumulations and travel
impacts, power outages could persist in some rural areas for a few
days. The combination of bitter cold temperatures tonight into
Tuesday will make this particularly hazardous for those that do lose
power. Residents should be prepared and have an emergency supply kit
ready in the event of a long duration power outage.

Overall the main forecast change was high confidence in ice/sleet
accumulations and less so on snow. Our analysis shows a classic setup
for freezing rain, especially across northwest Alabama and areas in
the Ice Storm Warning. A warm nose aloft of +5-7C at 850-925 mb
combined with surface temperatures in the mid to upper 20s means
we`re especially primed for icing in these areas. The window for
ice/sleet accumulations will vary by location, with the morning into
early afternoon being favored in northwest Alabama, the mid/late
morning and afternoon in north central Alabama and southern middle
Tennessee, and the afternoon/evening in northeast Alabama. Regardless
of what warning type you`re in or the main timing of the impacts,
this doesn`t change our overall message of hazardous and potentially
dangerous winter weather conditions being expected.

They do a great job IMO. Slow at times but overall good job
