Mesoscale Discussion 1264
NWS Storm Prediction Center Norman OK
0143 PM CDT Thu Jun 23 2022
Areas affected...portions of eastern Nevada and western Utah.
Concerning...Severe potential...Watch unlikely
Valid 231843Z - 232015Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated severe wind gusts are possible this
afternoon/evening.
DISCUSSION...Thunderstorms have started to develop across central
and eastern Nevada where temperatures have warmed into the 80s and
SPC mesoanalysis shows 250 J/kg MLCAPE. Some additional heating, in
addition to cooling temperatures aloft, should lead to additional
destabilization with MLCAPE around 400 to 600 J/kg this
afternoon/evening. Effective shear around 25 to 30 knots should
support multicell clusters or occasional rotating updrafts. The
primary threat will be damaging winds due to the inverted-v
thermodynamic profile and propensity for evaporatively cooled
downdraft acceleration. This threat is expected to continue into the
evening before waning after sunset. A watch is unlikely due to the
isolated nature of the threat in a weakly unstable environment.
