PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0840 PM CDT MON MAY 19 2025

...Severe thunderstorms expected over parts of the southern Plains
into the Ozarks and mid Mississippi Valley this evening and
overnight...

* LOCATIONS...
Western and Northern Arkansas
Missouri
Far Eastern Oklahoma
North-Central and Northeast Texas
Southern Illinois

* HAZARDS...
Widespread damaging winds, some hurricane force
Several tornadoes, a few intense
Scattered large hail, some baseball size

* SUMMARY...
A significant severe weather episode should continue tonight
across parts of the South-Central States. Strong tornadoes,
scattered to widespread damaging wind swaths, and very large
hail remain possible.

Preparedness actions...

Tornadoes at night can be particularly dangerous because they
are usually fast-moving and difficult to see. Stay tuned to
NOAA Weather Radio, weather.gov, or other media for watches and
warnings. A tornado watch means that conditions are favorable
for tornadoes to form during the next several hours. If a tornado
warning is issued for your area, move to a place of safety,
ideally in a basement or interior room on the lowest floor of a
sturdy building.
