* Tornado Watch for portions of
Southeastern Arkansas
Northeastern Louisiana
Central and southern Mississippi

A few tornadoes and a couple intense tornadoes likely
Scattered large hail and isolated very large hail events to 2.5
inches in diameter possible
Scattered damaging wind gusts to 70 mph possible
SUMMARY...A warm front will cross the region beneath strong vertical
shear. In that setting, clusters of severe thunderstorms, including
supercells, are forecast to move across the watch area overnight,
offering large hail, damaging gusts and at least a few tornadoes.
Some potential also exists for significant tornadoes (capable of EF2
or worse damage).
The tornado watch area is approximately along and 70 statute miles
north and south of a line from 50 miles south southwest of
Monticello AR to 20 miles east southeast of Meridian MS. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU8).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.

URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 17
NWS Storm Prediction Center Norman OK
650 PM CST Sat Jan 21 2017
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Central and southern Alabama
Western and central Florida Panhandle
Small part of southeastern Mississippi
Coastal Waters
* Effective this Saturday night and Sunday morning from 650 PM
until 300 AM CST.
...THIS IS A PARTICULARLY DANGEROUS SITUATION...
* Primary threats include...
Several tornadoes and a few intense tornadoes likely
Scattered damaging winds and isolated significant gusts to 75
mph possible
Isolated very large hail events to 2.5 inches in diameter
possible
SUMMARY...A cluster of storms now moving into extreme southwestern
Alabama is the first of what likely will be several areas of severe
weather moving across this watch overnight. As a warm front moves
northward across the region, conditions will moisten and destabilize
considerably amidst strong vertical shear. The resulting parameter
space is one often associated with long-lasting, intense tornadoes
rated EF2 or greater.
The tornado watch area is approximately along and 100 statute miles
north and south of a line from 80 miles north of Mobile AL to 50
miles south of Columbus GA. For a complete depiction of the watch
see the associated watch outline update (WOUS64 KWNS WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
