URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 519
NWS Storm Prediction Center Norman OK
240 PM MDT Wed Jul 16 2025

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of
  Eastern Colorado
  Nebraska Panhandle
  Southeast Wyoming

* Effective this Wednesday afternoon and evening from 240 PM
  until 1000 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
  A tornado or two possible

SUMMARY...Scattered thunderstorms developing near Interstate 25 will
continue to intensify this afternoon and move eastward across the
Watch.  Appreciably strong deep-layer shear will support a mix of
supercells and severe multicells across mainly the northern half of
the Watch.  Large hail and severe gusts will be the primary hazards
with the stronger storms, but a tornado is possible.  Severe
thunderstorms posing primarily a severe-wind risk are possible later
this evening as storms congeal into a likely cluster across
southeast Colorado.

The severe thunderstorm watch area is approximately along and 65
statute miles east and west of a line from 40 miles north of
Cheyenne WY to 25 miles west southwest of Springfield CO. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU9).

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.
