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.
