URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 534

NWS Storm Prediction Center Norman OK

325 PM MDT Thu Jul 30 2026



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of 

  Western into North-Central South Dakota



* Effective this Thursday afternoon and evening from 325 PM until

  900 PM MDT.



* Primary threats include...

  Scattered damaging wind gusts to 70 mph possible

  Isolated large hail events to 1 inch in diameter possible



SUMMARY...Widely scattered to scattered thunderstorms are forecast

to develop and intensify through the early evening.  A couple of

small thunderstorm clusters may evolve ahead of an upper disturbance

as some propensity for storms to produce outflow acts to consolidate

the severe risk by early evening.  Severe gusts 60 to 70 mph are the

primary hazard but isolated large hail near 1 inch in diameter is

possible too.



The severe thunderstorm watch area is approximately along and 80

statute miles east and west of a line from 50 miles east northeast

of Buffalo SD to 60 miles west southwest of Pierre SD. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU4).



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.
