Tornado Watch Number 292
NWS Storm Prediction Center Norman OK
1145 AM CDT Mon May 30 2022
The NWS Storm Prediction Center has issued a

600 PM CDT.
* Primary threats include...
Several tornadoes likely with a couple intense tornadoes

Scattered large hail and isolated very large hail events to 2.5
inches in diameter likely
SUMMARY...Severe storm development is underway from northeast
Nebraska into southeast South Dakota, and storms will spread quickly
northeastward through the afternoon. The storm environment favors a
mix of supercells and clusters/line segments, with all hazards
possible. The potential for strong tornadoes will increase through
the afternoon toward southwest Minnesota, especially with any
discrete supercells. Otherwise, very large hail (near tennis ball
size) and damaging outflow winds up to 75 mph can be expected.
The tornado watch area is approximately along and 70 statute miles
east and west of a line from 50 miles north northeast of Sioux Falls
SD to 25 miles east southeast of Norfolk NE. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU2).
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.
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 2.5 inches. Extreme turbulence and surface wind
gusts to 65 knots. A few cumulonimbi with maximum tops to 550. Mean
storm motion vector 21050.
