URGENT – IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 262
NWS Storm Prediction Center Norman OK
1155 AM CDT Fri May 16 2025

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of
Northern Arkansas
Southwestern Illinois
Central and Eastern Missouri
Far Eastern Oklahoma

* Effective this Friday morning and evening from 1155 AM until
700 PM CDT.

* Primary threats include…
A few tornadoes likely with a couple intense tornadoes possible
Widespread large hail and scattered very large hail events to 4
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely

SUMMARY…The airmass across the region continues to destabilize
amid strong low-level moisture advection and daytime heating. Robust
thunderstorm development is anticipated over the next few hours as
an approaching cold front interacts with this strong buoyant
airmass. Strong vertical shear is also in place, supporting
supercells as the primary storm mode. All severe hazards are
possible with these supercells, including very large hail up to 4″
in diameter and strong tornadoes.

The tornado watch area is approximately along and 80 statute miles
east and west of a line from 70 miles south of Harrison AR to 35
miles north northwest of Saint Louis MO. 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.

OTHER WATCH INFORMATION…CONTINUE…WW 260…WW 261…

AVIATION…Tornadoes and a few severe thunderstorms with hail

storm motion vector 24040.
