Areas affected...Parts of western/central NE

Concerning...Severe potential...Watch unlikely=20

Valid 130121Z - 130315Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated severe storms will remain possible through the
evening, with a threat of large hail and localized strong/severe
gusts.

DISCUSSION...An isolated supercell has recently developed across the
NE Panhandle, with 2-inch hail recently reported northeast of
Scottsbluff. While buoyancy is not overly strong, with MLCAPE of
500-1000 J/kg per recent mesoanalyses, deep-layer shear is quite
favorable (effective shear of 50+ kt), and the ongoing supercell may
continue to propagate along a weak surface boundary into
west-central NE. Hail (possibly very large in the short term) will
be the primary threat, though localized strong/severe gusts will
also be possible.=20

With the short-term threat expected to remain quite isolated, watch
issuance is currently considered unlikely. Some increase in storm
coverage is possible later tonight within a modest low-level warm
advection regime, though it remains unclear as to whether any
organized upscale growth (with a corresponding increase in
severe-wind risk) will occur.
