MD 0942 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF NORTHERN CALIFORNIA…NORTH AND CENTRAL NEVADA…AND WESTERN UTAH
Mesoscale Discussion 0942
NWS Storm Prediction Center Norman OK
0212 PM CDT Tue Jun 06 2023
Areas affected...portions of northern California...north and central
Nevada...and western Utah
Concerning...Severe potential...Watch unlikely
Valid 061912Z - 062115Z
Probability of Watch Issuance...5 percent
SUMMARY...Thunderstorms may produce hail and gusty winds through the
afternoon.
DISCUSSION...Thunderstorm development has been noted across portions
of northern California, north-central Nevada, and northern Utah in
the last hour. Temperatures have warmed quickly with little cloud
cover through the morning. Modifying the 12z soundings from LKN and
SLC produces a deeply mixed boundary layer with steep lapse rates
through the profile. Surface objective analysis indicates MLCAPE
around 500 J/kg amid modest deep layer shear around 30-35 kts. This
environment will favor multi-cell clusters, with potential for a few
instances of severe wind and hail. Given the lack of deeper
moisture, the spatial extent of this threat will likely remain too
small for watch issuance.
