TORNADO WATCH BOXES AND AVIATION WATCH BOXES IN PINK COLOR

 ACTIVE WARNINGS IN WATCH AREA SO TAKE COVER
 
 URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 18
   NWS Storm Prediction Center Norman OK
   745 PM CST Sat Jan 21 2017

   The NWS Storm Prediction Center has issued a

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

   * Effective this Saturday night and Sunday morning from 745 PM
     until 300 AM CST.

   * Primary threats include...
     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.

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 15...WW 16...WW 17...

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 2.5 inches. Extreme turbulence and surface wind
   gusts to 60 knots. A few cumulonimbi with maximum tops to 450. Mean
   storm motion vector 25030.

 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.

   &&

   OTHER WATCH INFORMATION...CONTINUE...WW 15...WW 16...

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 2.5 inches. Extreme turbulence and surface wind
   gusts to 65 knots. A few cumulonimbi with maximum tops to 450. Mean
   storm motion vector 25030.
