[html]MD 0730 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEAST SD
Mesoscale Discussion 0730
NWS Storm Prediction Center Norman OK
1150 PM CDT Wed May 11 2022
Areas affected...Southeast SD
Concerning...Severe potential...Watch unlikely
Valid 120450Z - 120645Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated strong to severe storms may produce hail
overnight. Coverage of severe storms is expected to be limited,
thus a watch is not likely. However, trends will be monitored.
DISCUSSION...Isolated thunderstorms have begun to form over southern
SD and northern NE. This appears to be associated with low-level
warm/moist advection and lift above a relatively cool/stable
boundary layer. Forecast soundings suggest this activity is rooted
around 700mb, but steep mid-level lapse rates are yielding around
2000 J/kg of MUCAPE. Effective shear values are sufficient for a
few elevated rotating storms overnight across southeast SD capable
of large hail. Current indications are that intense storms will be
isolated and a watch may not be needed. But trends will continue to
be monitored.
