PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1050 AM CST SAT DEC 21 2013

...WIDESPREAD SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE LOWER
MISSISSIPPI TO OHIO VALLEYS THIS AFTERNOON AND TONIGHT...

The NWS Storm Prediction Center in Norman, OK is forecasting the
development of a few intense tornadoes and widespread damaging winds
over parts of the Lower Mississippi to Ohio valleys this afternoon
and tonight.

The areas most likely to experience this activity include:

       Northwest Alabama
       Southeast Arkansas
       Central and Northeast Louisiana
       much of Mississippi
       Western and Middle Tennessee

Elsewhere, severe storms are also possible from parts of the Ohio
Valley to the Gulf Coast.

A potent jet stream disturbance now over west Texas will track
northeast into Red River Valley later today, before accelerating
northeast into the mid-Mississippi Valley tonight and early Sunday.

Associated with this disturbance, an area of low pressure now
forming over northeast Texas will become better organized as it
moves northeast into southern Arkansas this afternoon, northwest
Tennessee this evening, and the lower Ohio Valley early Sunday.

Ahead of the low, a broad flow of unseasonably warm and humid air
will surge north from the western Gulf of Mexico into the lower
Mississippi, the lower Tennessee, and the Ohio Valleys through early
Sunday.

The increasing moisture and strong wind field that will accompany
the jet stream impulse will create an environment favorable for
bands of rotating thunderstorms capable of both potentially strong
tornadoes and damaging wind over a broad swath extending from
eastern Texas and southern Louisiana northeastward into the lower
Mississippi and lower Tennessee Valleys.

Although the severe weather threat is expected to be greatest this
afternoon through early tonight over parts of Louisiana, Arkansas,
Mississippi, and Tennessee, a more conditional risk for tornadoes
and damaging winds will persist into early Sunday from the central
Gulf Coast northeast into the mid-Ohio Valley.

State and local emergency managers are monitoring this developing
situation. Those in the threatened area are urged to review severe
weather safety rules and to listen to radio, television, and NOAA
Weather Radio for possible watches, warnings, and statements later
today.
