PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0407 AM CDT THU APR 03 2014

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE OZARKS REGION TO
PARTS OF THE MID-SOUTH AND LOWER OHIO VALLEY THIS AFTERNOON AND
TONIGHT...

The NWS Storm Prediction Center in Norman, OK is forecasting the
development of tornadoes, large hail and damaging winds from the
Ozarks region to parts of the Mid-South and lower Ohio Valley this
afternoon and tonight.

The areas most likely to experience this activity include:

most of Arkansas
southern Illinois
southwestern Indiana
western Kentucky
northern Louisiana
southern and eastern Missouri
northwestern Mississippi
western Tennessee

Elsewhere, severe storms are also possible from the mid-Mississippi
Valley to western Ohio and southwestward to central Mississippi,
eastern Oklahoma and southeast Texas.

A strong disturbance 3-7 miles above ground will move northeastward
out of the Four Corners and Rockies today, causing winds to
strengthen over the outlook area. As that happens, a cold front
will overtake a dryline from north to south across parts of eastern
Kansas, Missouri and eastern Oklahoma. When the front and dryline
encounter sunshine-heated and richly moist air to their east,
thunderstorms should erupt and become severe, with help from that
increase in surrounding winds.

The greatest threat for very large and damaging hail will be with
the early, western storms in Missouri and Arkansas this afternoon
and evening, while the damaging-wind hazard will ramp up this
evening and possibly overnight in the Mississippi Valley.
Tornadoes--some strong with EF2 or worse damage--also are possible.
A separate band of severe thunderstorms, also offering tornado and
severe-wind risk, may form tonight over parts of the Mississippi
Delta region--in and near the southern part of the moderate-risk
area.

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.
