Areas affected...Portions of southeast Wyoming...southwest Nebraska
and eastern Colorado

Concerning...Severe Thunderstorm Watch 268...

Valid 270115Z - 270215Z

The severe weather threat for Severe Thunderstorm Watch 268
continues.

SUMMARY...A short-term continuation of the severe weather threat may
necessitate a local watch extension in time beyond the scheduled 02z
expiration of WW 268, however a new watch is not anticipated.

DISCUSSION...Isolated severe thunderstorms were in progress across
the watch area at 0115z, with a tornado recently reported in Yuma,
County CO. Storms posing a more sustained severe threat will be
moving into recently issued WW 271 by around 02z, however some
severe risk will likely exist in WW 268 for 1-2 hours beyond 02z as
modest buoyancy and sufficient effective shear remains in place.
Thus, a local watch extension in time for portions of WW 268 may be
needed prior to expiration.
