[html]MD 1277 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL SOUTH DAKOTA
Mesoscale Discussion 1277
NWS Storm Prediction Center Norman OK
0245 PM CDT Fri Jun 24 2022
Areas affected...Central South Dakota
Concerning...Severe potential...Watch possible
Valid 241945Z - 242115Z
Probability of Watch Issuance...60 percent
SUMMARY...Large hail and damaging winds are possible with storms in
central/eastern South Dakota into north-central Nebraska. A watch is
possible for some of these areas this afternoon.
DISCUSSION...Visible satellite shows deepening cumulus towers from
north-central Nebraska into central South Dakota within the surface
trough. Capping continues to erode along and ahead of the trough
axis. With mid-level ascent continuing to approach the area, widely
scattered to scattered storm development is possible this afternoon.
Effective shear of 30-40 kts across the trough axis will support
initially discrete storms that will be capable of large hail and
damaging wind gusts. Storms may take some time to intensify as
moisture and MLCAPE (2500-3500 J/kg) increase in eastern South
Dakota. A severe thunderstorm watch will likely be considered for
parts of these areas this afternoon.
