Severe Thunderstorm Watch Number 559
NWS Storm Prediction Center Norman OK
340 PM MDT Mon Aug 10 2026

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Northeast Colorado
  Far Northwest Kansas
  Western Nebraska

* Effective this Monday afternoon and evening from 340 PM until
  1100 PM MDT.

* Primary threats include...
  Scattered damaging winds and isolated significant gusts to 75
    mph possible
  Isolated large hail events to 1.5 inches in diameter possible

SUMMARY...Thunderstorm coverage is expected to increase over the
next few hours across the central High Plains. These storms are
forecast to progress eastward into the hot and deeply mixed airmass
downstream across northeast Colorado, western Nebraska, and far
northwest Kansas. Moderate buoyancy exists downstream as well, and
the overall environment supports the potential for strong to severe
gusts, particularly as cold pools amalgamate. A few instances of
hail are also possible early in the convective cycle.

The severe thunderstorm watch area is approximately along and 65
statute miles east and west of a line from 70 miles northwest of
Mullen NE to 40 miles south of Burlington 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.
