URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 131
NWS Storm Prediction Center Norman OK
330 PM CDT Fri Apr 17 2026

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of
Central and Northeast Illinois
Northeast Missouri
Lake Michigan

* Effective this Friday afternoon and evening from 330 PM until
1100 PM CDT.

* Primary threats include...
A couple tornadoes possible
Widespread damaging winds likely with isolated significant gusts
to 75 mph possible
Scattered large hail and isolated very large hail events to 2.5
inches in diameter possible

SUMMARY...Thunderstorms have intensified across northeast MO, with
some additional intensification possible as they continued
northeastward into central IL. The airmass across the region
supports supercells capable of all severe hazards, including very
large hail and tornadoes. Another round of storms will follow in the
wake of the ongoing storms later this evening as a cold front moves
across the region. Wind gusts will be the primary risk with the
storms along the front, but line-embedded circulations are possible
as well.

The tornado watch area is approximately along and 75 statute miles
east and west of a line from 50 miles west northwest of Valparaiso
IN to 30 miles southeast of Jefferson City 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.
