205 PM CDT Sun Oct 24 2021
The NWS Storm Prediction Center has issued a

Extreme west central Illinois
* 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 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).
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.
