URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 360
NWS Storm Prediction Center Norman OK
555 PM MDT Mon Jun 13 2022
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Western South Dakota
Northeast Wyoming
* Effective this Monday afternoon and evening from 555 PM until
1100 PM MDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 75
mph likely
Scattered large hail and isolated very large hail events to 3
inches in diameter likely
A tornado or two possible
SUMMARY...Clusters of storms are forming in eastern Wyoming, and
convection is expected to increase in coverage/intensity through
this evening into western South Dakota. The environment supports
the potential for supercells with isolated very large hail up to 3
inches in diameter, while clustering of storms in time will favor
the potential for severe outflow gusts up to 75 mph. A tornado or
two may also occur with the more persistent supercells, or with
embedded circulations in any storm clusters/line segments.
The severe thunderstorm watch area is approximately along and 75
statute miles east and west of a line from 70 miles east northeast
of Buffalo SD to 70 miles south of Rapid City SD. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU0).
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.

AVIATION...A few severe thunderstorms with hail surface and aloft to
