426 ACUS11 KWNS 030002 SWOMCD SPC MCD 030001 MNZ000-SDZ000-NEZ000-030130- Mesoscale Discussion 1138 NWS Storm Prediction Center Norman OK 0701 PM CDT Sun Jun 02 2024 Areas affected...Northern Plains Concerning...Severe Thunderstorm Watch 379... Valid 030001Z - 030130Z The severe weather threat for Severe Thunderstorm Watch 379 continues. SUMMARY...Severe threat continues across ww379. DISCUSSION...Several supercells have developed within low-level warm advection regime across eastern SD into southwest MN. This activity is maturing immediately ahead of a weak surface low that is forecast to track across eastern SD into northwest MN later this evening. Latest diagnostic data suggests MLCAPE is in excess of 2000 J/kg across this region and the environment remains amply sheared for organized updrafts. Large hail appears to be common with the most robust updrafts and this is the primary risk with storms this evening. Even so, a tornado or two can not be ruled out with the more discrete supercells, especially near the warm front where low-level shear is a bit stronger than the western half of the watch. Organized severe storms are expected to gradually spread into southwest MN over the next few hours. ..Darrow.. 06/03/2024 ...Please see www.spc.noaa.gov for graphic product...
