Major Winter Storm Impacts Southeast Today – Bitter Cold Grips Heartland

Temperatures still remain 20 to 35 degrees below normal throughout the Plains, Mississippi Valley, and lower Great Lakes.

Significant icing and heavy snowfall

A major winter storm will impact the Southeast U.S. today bringing with it significant icing and heavy snowfall. This system will track into the Ohio Valley, Mid-Atlantic, and Northeast U.S. Thursday into Friday, producing similar impacts.

Over 100 million Americans are under Winter Storm Warnings, Winter Storm Watches, or Winter Weather Advisories as another round of impactful winter weather tracks from the Southern Plains to the East Coast…

The developing winter storm to produce heavy snow and treacherous ice accumulations from the South Central U.S. to Mid-Atlantic…

Bitter cold expected to continue. Showers and thunderstorms to track across the Southeast; Pacific storm system ushers in valley/coastal rain and heavy mountain snow to the Northwest.

Areas of snow and freezing rain to envelope much of the South Central U.S. this morning.

The snowfall will extend from Arkansas and the Mid-South to the central Appalachians with accumulations of 3 to 6 inches likely. Heavier amounts over 8 inches are possible in parts of south-central Arkansas.

Just south of the snow zone, significant ice accumulations are expected from east Texas and the Lower Mississippi Valley to the Virginia and North Carolina Piedmont by Wednesday night.

Ice accumulations of a quarter to a half inch are forecast in parts of east Texas, northern Louisiana, southern Arkansas, and western Mississippi with crippling totals over a half inch also possible. The same range of ice accumulations are anticipated in the North Carolina and Virginia Piedmont Wednesday night into Thursday with even some localized amounts as high as three-quarters of an inch.

Dangerous travel, numerous power outages, extensive tree damage

In those areas, residents can expect dangerous travel conditions, numerous power outages, and extensive tree damage. Meanwhile, periods of moderate-to-heavy snow will breakout across the northern Mid-Atlantic Thursday with some locations switching over to sleet and/or freezing rain.

Heavy snow may work its way to southern New England Thursday afternoon into Thursday night. Snowfall totals are subject to how much sleet and freezing rain mixes in, but the sheer amount of wintry precipitation will cause treacherous travel conditions and many travel delays.

As much as a foot (30 cm) of snow in the Appalachians of Virginia and West Virginia

The heaviest snow totals are likely in the Appalachians of Virginia and West Virginia where as much as a foot is possible. In coming days the number of record cold maximum and minimum temperatures will not be as common (the bulk of which are occurring in the South Central U.S.), temperatures will still remain 20 to 35 degrees below normal throughout the Plains, Mississippi Valley, and lower Great Lakes.

Morning lows in the single digits or below zero look to continue both today and Thursday in parts of the Great Plains.

Impending winter storm arrives Thursday morning

Bitter cold has pushed east into the Mid-Atlantic and Northeast ahead of the impending winter storm that arrives Thursday morning. High temperatures will struggle to eclipse the freezing mark both today and Thursday in these regions.

Out West, after a day of tranquil weather on Wednesday, a Pacific storm system ushers in another round of valley/coastal rain and mountain snow on Thursday. Locally heavy rainfall is possible in far northwestern California and far southwestern Oregon on Thursday. Meanwhile, the Cascades are likely to receive another foot of snow with heavy snow working its way into the northern Rockies Thursday night and continuing into Friday morning.

  1. Robert, are there any studies about anything like this?

    What if the jet stream flow during warmer times is actually one of two meta-stable states of the atmosphere?

    I was thinking about this last night… when it’s warmer, high-altitude equatorial air advects poleward, trapping cold polar air in a circular jet stream.

    When it’s colder, that equatorial air advection is less, thus the jet stream ‘wanders’… so what happens when high-altitude equatorial air advection is so low that the jet stream is no longer contained whatsoever?

    What if, rather than high-altitude West-to-East flow during warm periods, during cold periods it establishes lower-altitude roughly North-South flow (large isolated flows of cold air southward, large isolated flows of warm air northward, alternating warm | cold | warm | cold, etc.), with the flow skewed by planetary rotation and the presence of mountains?

    That would explain a lot… like why, during the last Ice Age, archaeological finds in the Arctic show that humans comfortably lived there (that would be an area where warm air was flowing equator-to-pole), whereas further south there were miles-thick glaciers (that would be an area where cold air was flowing pole-to-equator)… like why, during the last Ice Age, global temperature didn’t decrease all that much, but miles-thick glaciers could form… like why, during the last Ice Age, it could persist despite solar cycles subsequently ramping up (once a meta-stable state is reached, it requires a large enough change to ‘get it over the hump’ into the other meta-stable state).

    What we may be experiencing with the ‘wavy’ jet stream is the attempt by the system known as ‘Earth’ to reach one of the two meta-stable states. Once it reaches one of the two meta-stable states, it requires a large enough change to flip it back over to the other meta-stable state.

    So a “The Day After Tomorrow” scenario could be possible, with persistent severe temperature drops for certain areas (where air flows pole-to-equator), whereas in other areas, temperature would be benign (where air flows equator-to-pole).

  2. This is named winter storm #22 and right now it’s snowing in: Denver, St Jo, Texarkana, Little Rock, Memphis ,Tupelo, Jackson, Bowling Green, and Nashville. And it’s heading for: Pittsburg, Cincinnati, Charleston, DC, NY City, and Boston.
    Still waiting for a response from Joe on the National State of Emergency besides “Where the hell are we ?”. Wake up Joe, millions of folks are freezing !!!!

  3. What do you want to bet that come August, the warmists will concoct another report about how this was the warmest year ever?

  4. Snowing now in: Del Rio and Eagle Pass Texas on the Mexican Border; San Antonio, Austin, up tp Waco, and east to Lufkin TEXAS, and up into Louisiana and MISSISSIPPI. AGAIN. WAKE UP JOE! ! ! !
