...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR CENTRAL AND
SOUTHWEST NEBRASKA...DEEP SOUTH TEXAS...

...SUMMARY...
Widely scattered severe thunderstorms capable of producing hail and
severe gusts remain possible this evening in parts of central and
southwest Nebraska and deep south Texas.

...Central Great Plains into the eastern Dakotas...
Water-vapor imagery shows several weak disturbances embedded within
west-southwesterly mid-level flow over the north-central and
northern parts of the Great Plains.  An ongoing and organized
cluster of thunderstorms will likely continue to move east across
southwest and central NE this evening.  Relatively steep mid-level
lapse rates will aid in a risk for hail/severe gusts with he
stronger storms.  Other more widely spaced thunderstorms extend from
parts of eastern CO northward into the Dakotas.  The severe risk
will likely remain localized this evening with this activity before
it diminishes by mid-late evening.

...South TX...
Modest northwesterly flow aloft in association with a weak mid-level
disturbance over south-central TX will promote a gradual southward
movement of storms this evening.  The 00 UTC Brownsville, TX raob
showed an elongated hodograph with steep 700-500 mb lapse rates (8.3
deg C/km and 2000 J/kg MLCAPE).  It is plausible the risk for a
couple of supercells/storm cluster continues through the evening
this activity pushes offshore/south of the Rio Grande.  Large hail
and severe gusts will be the primary threats with the stronger
storms.
