ZCZC SPCSWOMCD ALL ACUS11 KWNS 040028 SPC MCD 040028 MNZ000-SDZ000-NDZ000-040300- Mesoscale Discussion 1350 NWS Storm Prediction Center Norman OK 0728 PM CDT Sun Jul 03 2022 Areas affected...Northeast South Dakota...Southeast North Dakota...Far Western Minnesota Concerning...Severe potential...Watch possible Valid 040028Z - 040300Z Probability of Watch Issuance...40 percent SUMMARY...The severe threat may increase across parts of northeast South Dakota and southeast North Dakota over the next couple of hours. Weather watch issuance may become necessary across parts of the eastern Dakotas into far western Minnesota later this evening. DISCUSSION...Latest satellite imagery shows an east-to-west corridor of convective development currently taking place across northeast South Dakota. This corridor is located within an area of outflow, near a minimum of instability from earlier storms. Further to the north, into southeast North Dakota, surface heating into the lower 80s F, has resulted in moderate destabilization. The RAP suggests MLCAPE is currently in the 2000 to 2500 J/kg range across southeast North Dakota. The HRRR develops storms near Mobridge, South Dakota later this evening, and moves a small cluster east-northeastward across southeast North Dakota. The instability combined with moderate deep-layer shear, evident on WSR-88D VWPs, will be favorable for a severe threat. Steep mid-level lapse rates will make isolated large hail possible with rotating cells. Wind damage will may also occur, especially if convective coverage increases later this evening. ..Broyles/Guyer.. 07/04/2022 ...Please see www.spc.noaa.gov for graphic product...
