URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 303
NWS Storm Prediction Center Norman OK
110 PM CDT Tue May 20 2025

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of
Eastern Arkansas
Southern Illinois
Western Kentucky
Southeast Missouri
Northern Mississippi
West Tennessee

* Effective this Tuesday afternoon and evening from 110 PM until
800 PM CDT.

* Primary threats include...
A few tornadoes likely with a couple intense tornadoes possible
Scattered large hail and isolated very large hail events to 2.5
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely

SUMMARY...Thunderstorms will intensify across the watch area this
afternoon in a very moist and unstable air mass. A few supercells
are expected, capable of large hail, damaging winds, and a few
tornadoes.

The tornado watch area is approximately along and 110 statute miles
east and west of a line from 60 miles east northeast of Poplar Bluff
MO to 35 miles south of Greenville MS. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS

Mesoscale Discussion 0898
NWS Storm Prediction Center Norman OK
0107 AM CDT Tue May 20 2025

Areas affected...far eastern Missouri...southeast
Illinois...southwest Indiana...and western Kentucky

Concerning...Severe potential...Watch likely

Valid 200607Z - 200730Z

Probability of Watch Issuance...80 percent

SUMMARY...Wind damage and QLCS tornado threat may persist east of Tornado Watch 298. An extension in space of the existing watch or a new watch may be needed.

DISCUSSION...A long-lived linear MCS continues to move east across Missouri this morning. This MCS has a history of producing sporadic wind damage along with transient to slightly longer lived low-level circulations/QLCS tornadoes.

The environment along the path of the MCS Monday evening was unstable and highly sheared. SPC mesoanalysis shows the environment ahead of the MCS remains highly sheared -- 40-50 knots effective deep-layer shear -- and remains unstable -- with mixed-layer CAPE between 1000-2000 J/kg. SPC Mesoanalysis also shows that this region is a relative minimum in convective inhibition, which would support a continued wind threat/QLCS tornado threat.

Either a local extension of Tornado Watch 298 or a new watch will likely be needed within the next hour.

"Laurel County resident Chris Cromer said he got the first of two tornado alerts on his phone around 11:30 p.m. or so, about a half-hour before the tornado struck. He and his wife grabbed their dog, jumped in their car and scrambled to the crawlspace at a relative’s nearby home because the couple’s own crawlspace is small.

Edit: The city apparently removed that layer from their ArcGIS server. You can still see it on the screenshot below but it will not appear on the GISsurfer map.
----------
#StLouis #Missouri took a serious #tornado hit today. The city ArcGIS server seems to already have a layer showing the approximate track.

*Caution!* The city ArcGIS server does not specifically identify this data as pertaining to today's tornado. But the location seems to match with other info I have seen.

2.5 inches in diameter likely
Widespread damaging winds and isolated significant gusts to 80
mph likely

SUMMARY...Supercells ongoing across eastern MO and western IL are

downstream across the region. All severe hazards, including very
large hail up to 2.5" to 3" in diameter and strong to intense
tornadoes, are possible.

The tornado watch area is approximately along and 95 statute miles
east and west of a line from 35 miles north northwest of
