URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 531

NWS Storm Prediction Center Norman OK

205 PM CDT Sun Oct 24 2021



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Extreme west central Illinois

  Missouri



* Effective this Sunday afternoon and evening from 205 PM until

  1000 PM CDT.



* Primary threats include...

  A few tornadoes likely with a couple intense tornadoes possible

  Scattered damaging winds and isolated significant gusts to 75

    mph likely

  Scattered large hail likely with isolated very large hail events

    to 2 inches in diameter possible



SUMMARY...Scattered severe storm development is expected this

afternoon along and ahead of a cold front moving from Kansas toward

western Missouri.  The storm environment will initially favor

supercells capable of producing a couple of strong tornadoes, large

hail, and damaging winds.  Later this evening, the threat for wind

damage will increase as storms evolve into a more linear mode toward

eastern Missouri, while the threat for tornadoes will persist with

circulations embedded in the line of storms.



The tornado watch area is approximately along and 95 statute miles

east and west of a line from 10 miles east northeast of Kirksville

MO to 55 miles south southeast of Springfield MO. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU1).



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.



&&



AVIATION...Tornadoes and a few severe thunderstorms with hail

surface and aloft to 2 inches. Extreme turbulence and surface wind

gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean

storm motion vector 24045.
