URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 636
NWS Storm Prediction Center Norman OK
430 PM CST Tue Nov 18 2025
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Extreme Southern Illinois
Western Kentucky
Southeast Missouri
Northwest Tennessee
* Effective this Tuesday afternoon and evening from 430 PM until
1000 PM CST.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
Isolated damaging wind gusts to 65 mph possible
A tornado or two possible
SUMMARY...A cluster of intense thunderstorms will likely track
southeastward across the watch area this evening. Large hail and
perhaps a tornado will be possible.
The severe thunderstorm watch area is approximately along and 55
statute miles north and south of a line from 15 miles west of Poplar
Bluff MO to 65 miles southeast of Paducah KY. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU6).
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.

SPC: 40% chance of a Severe T-Storm Watch being issued for part of the tri-state (Slight Risk area)

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE LOWER OHIO VALLEY AND MIDDLE MISSISSIPPI VALLEY...

...SUMMARY...
Widely scattered severe storms are possible across parts of the
middle Mississippi Valley and lower Ohio Valley this afternoon and
evening.

...20Z Update...
The primary change with this update was the addition of a Slight
Risk (2/5) over parts of the Lower OH Valley and Mid MS Valley --
driven by 15-percent hail probabilities. The latest visible
satellite imagery shows an increasingly agitated boundary-layer
cumulus field evolving across southeast MO -- in the vicinity of a
frontal wave/weak surface low. Continued heating amid increasing
boundary-layer moisture ahead of this feature should erode
inhibition through the remainder of the afternoon and support
isolated to widely scattered thunderstorms along a pre-frontal
surface trough. Any storms that form will be moving into an
environment characterized by around 50 kt of effective shear and
weak-moderate surface-based buoyancy. This will conditionally favor
discrete/semi-discrete supercells capable of producing large hail
and locally strong gusts. While less certain, a couple of tornadoes
cannot be ruled out if established supercells evolve, given
sufficient low-level hodograph curvature. Elsewhere, the Marginal
Risk was expanded slightly northward to account for an ongoing
elevated hail risk.
