URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 532
NWS Storm Prediction Center Norman OK
345 PM CDT Sun Oct 24 2021

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Northern and western Arkansas
  Eastern Oklahoma

* Effective this Sunday afternoon and evening from 345 PM until
  1100 PM CDT.

* Primary threats include...
  A few tornadoes possible
  Scattered damaging wind gusts to 70 mph likely
  Scattered large hail events to 1.5 inches in diameter likely

SUMMARY...Scattered severe storm development is expected late this
afternoon along and just ahead of a cold front moving southeastward
across eastern Oklahoma.  The storm environment ahead of the front
appears favorable for a mix of supercells and storm clusters capable
of producing damaging winds and large hail.  The more
rightward-moving supercells may also pose the threat for a few
tornadoes this evening.

The tornado watch area is approximately along and 90 statute miles
east and west of a line from 15 miles north of Harrison AR to 50
miles south of Poteau OK. For a complete depiction of the watch see
the associated watch outline update (WOUS64 KWNS WOU2).

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.

surface and aloft to 1.5 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean
