URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 507
NWS Storm Prediction Center Norman OK
220 PM CDT Fri Jul 11 2025

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Far West-Central Illinois
  Extreme Northeast Kansas
  Northern Missouri

* Effective this Friday afternoon and evening from 220 PM until
  1000 PM CDT.

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

SUMMARY...Thunderstorm coverage and intensity is forecast to
increase from northeast KS across northern MO and into west-central
IL this afternoon. Strong to extreme buoyancy is in place across the
region, supporting the potential for robust updrafts. Vertical shear
is weak, which could limit storm organization, but the intense
updrafts and related water loading could result in numerous strong
downbursts. A few instances of hail could occur as well, but warm
temperatures should preclude a greater hail threat.

The severe thunderstorm watch area is approximately along and 45
statute miles north and south of a line from Leavenworth KS to 35
miles east southeast of Quincy IL. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU7).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for 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. Severe thunderstorms can and occasionally do produce
tornadoes.
