NWS Storm Prediction Center Norman OK
210 AM CDT Thu Jun 11 2026

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Western and Central Iowa
  Northern Missouri

SUMMARY...Mostly elevated strong to severe thunderstorms will
continue to develop overnight, initially across
south-central/eastern Nebraska, while eventually expanding into
western/central Iowa and far northern Missouri. This will include
the Interstate 80 corridor. Large hail is expected to be the most
common hazard, but surface-based storm potential could increase
mainly toward/after sunrise including what could be an increasing
damaging wind risk.

The severe thunderstorm watch area is approximately along and 60
statute miles north and south of a line from 40 miles west of
Kearney NE to 30 miles north of Ottumwa IA. 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
3 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
25025.
