URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 314
NWS Storm Prediction Center Norman OK
140 PM CDT Fri Jun 25 2021

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  South-central/Eastern Kansas
  Western Missouri

* Effective this Friday afternoon and evening from 140 PM until
  900 PM CDT.

* Primary threats include...
  Scattered large hail likely with isolated very large hail events
    to 2 inches in diameter possible
  Scattered damaging wind gusts to 70 mph likely
  A tornado or two possible

SUMMARY...Clusters of storms will continue to develop this afternoon
along/south of a modifying boundary that extends from
south-central/eastern Kansas into western Missouri. Some supercells
and sustained multicells can be expected, with storms likely to
become more numerous by early evening. Damaging winds and large hail
are the primary risks, although there is a possibility that some
tornado risk could materialize later this afternoon/early evening
particularly for storms interacting with the remnant boundaries.

The severe thunderstorm watch area is approximately along and 65
statute miles north and south of a line from 30 miles west southwest
of Hutchinson KS to 25 miles east of Knob Noster MO. 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.

&&

AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 550. Mean storm motion vector
26025.
