Areas affected...eastern Wyoming...northeastern Colorado...western
Nebraska
Concerning...Severe potential...Watch unlikely
Valid 230119Z - 230215Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated wind and hail risk possible over the next couple
of hours.
DISCUSSION...A cluster of thunderstorms have developed and
strengthened across eastern Wyoming near a gradient of MLCAPE around
250-500 J/kg. Within this region, moisture and forcing remains
overall limited, with dew points in the upper 40s to 50s. Lack of
deeper moisture, loss of daytime heating, and lack upper level
support will likely keep the overall severe threat low. Given deep
layer shear around 45-50 kts, a few briefly organized storms may
produce instances of hail and gusty wind will be possible,however, a
watch is unlikely to be needed.
