URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 207
NWS Storm Prediction Center Norman OK
355 PM CDT Sat Jun 23 2018

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Parts of central and western Oklahoma
  Extreme northwest Texas

* Effective this Saturday afternoon and evening from 355 PM until
  1000 PM CDT.

* Primary threats include...
  Scattered large hail and isolated very large hail events to 2.5
    inches in diameter possible
  Scattered damaging wind gusts to 70 mph possible
  A tornado or two possible

SUMMARY...Thunderstorm development is expected in the next couple of
hours along a stalled boundary near I-40, from the southern Oklahoma
City metro area westward.  The storm environment favors supercells
capable of producing very large hail and damaging winds.  A modest
increase in low-level shear this evening could also support the
threat for an isolated tornado, though this threat is secondary to
the hail and wind.  Some clustering of storms and southward
movement/development will be possible later this evening across the
southern portions of the watch area.

The severe thunderstorm watch area is approximately along and 50
statute miles north and south of a line from 30 miles west southwest
of Clinton OK to 50 miles north northeast of Ardmore OK. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU7).

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.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 205...WW 206...

AVIATION...A few severe thunderstorms with hail surface and aloft to
2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 600. Mean storm motion vector
30015.

NWS Storm Prediction Center Norman OK
220 PM MDT Sat Jun 23 2018

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  East central and southeast Colorado
  Western Kansas
  Extreme northeast New Mexico
  The extreme western Oklahoma Panhandle

* Effective this Saturday afternoon and evening from 220 PM until
  900 PM MDT.

* Primary threats include...
  Scattered large hail and isolated very large hail events to 2
    inches in diameter possible
  Scattered damaging wind gusts to 70 mph possible

SUMMARY...Ongoing thunderstorms from Limon to Goodland should expand
some in coverage and intensify the remainder of the afternoon, with
some potential for storms to coalesce into a cluster and move
southeastward this evening.  The initial threat will be large hail
with splitting supercells, while the threat for damaging winds
should increase this evening as a cluster forms.  Farther south,
more isolated storms could form east of the high terrain.  Any
sustained storms will likely be supercells capable of producing
large hail for a few hours this afternoon/evening.

The severe thunderstorm watch area is approximately along and 75
statute miles east and west of a line from 25 miles west northwest
of Burlington CO to 30 miles south of Springfield CO. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU6).

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.

OTHER WATCH INFORMATION...CONTINUE...WW 205...

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