Wintry King Kong Winter Storm Potential Feb 13th-16th

From Huntsville NWS:
From the afternoon discussion from the Huntsville National Weather Service office:
Confidence continues to increase that a significant winter/ice event
will impact the area on Monday

The trough axis will swing across the area Monday night, and a stout punch of subfreezing air will make it all the way through the
forecast area. We believe this will be where impacts are maximized,
as subfreezing temperatures will outpace the colder air aloft,
creating a rather messy winter weather situation. Believe most of the forecast area will be dealing with ice by this point, especially
areas along and west of I-65. As the colder air begins to arrive
aloft, could see a transition from freezing rain to sleet late
Monday, especially over NW AL and SM TN. There could be a brief
window for some snow accumulation over far NW AL late Monday night, but this really depends on how quickly the colder air arrives aloft, and if this happens before the dry air sinks in. Any impacts will likely linger through Tuesday night, as high temps struggle to make it above freezing until Wednesday.

We continue to grow more confident that widespread
travel impacts will occur, especially over northwest Alabama and
southern middle Tennessee. Unfortunately, ice is a lot harder to
mitigate when it comes to travel, and roads can become hazardous
quickly. Depending on ice accretion, some power outages could be
possible. If this happens, it could take a while for power to be
restored in some areas. Temperatures will remain below freezing
across much of the area until Wednesday morning, even dropping into
the teens in northwestern AL Monday night. This will be especially
hazardous for those who are without power. It is important to monitor
this situation over the holiday weekend and begin prepping for these
potential impacts now.

Brent you are under a Winter Storm Warning. The headline reads " Historic Winter Storm to impact the region Sunday and Monday." Blowing and drifting snow. Wind chills below 0.

(1) A historic winter storm is poised to impact North and Central
Texas, with impacts beginning as early as Saturday morning,
continuing through Monday.

(2) Extremely cold temperatures, rivaling the December 1989 Arctic
Outbreak, are forecast on Sunday and into Monday, with prolonged
much below normal temperatures expected to continue through next
week.

(3) Major impacts resulting in severe stress to the region`s
infrastructure (particularly power, water, and highways) are
likely. Regional travel will be crippled for days.

(4) Additional frozen precipitation will be possible toward the
middle of next week, though confidence is low in the details at
this time.

They're still being somewhat conservative with the amounts (3-6").

We are declaring Monday and Tuesday First Alert Weather Days due to the threat for icy roads, power outages and damage to trees. The greatest threat for power outages and damage to trees will be over northwest Alabama and southern Middle Tennessee beginning Monday afternoon. These areas could see ¼ to ½ inch of ice accumulation. If there is a changeover to sleet or snow there will be less ice and that is good news. However bridges and overpasses could become slick by Monday afternoon if temperatures drop into the 20s. Farther east the threat for freezing rain will move into the Huntsville metro area after 4pm Monday with up to ¼” of ice possible. We are still not sure how much of a period of sleet and snow we could see, but up to 1” of snow will be possible if the colder air moves in a little faster. As we get later into the afternoon and evening hours Monday we will watch temperatures begin to drop into the lower and middle 20s. The roads will likely not have time to dry and it is possible we could have hazardous driving conditions develop across all of North Alabama and Middle Tennessee into Monday night. These conditions could last into the afternoon on Tuesday if temperature do not get above freezing and if cloud cover lingers. Stay tuned for updates on this developing weather system.
