Mesoscale Discussion 1627 NWS Storm Prediction Center Norman OK 0437 AM CDT Mon Jul 15 2024 Areas affected...Far Southeast North Dakota...Far Northeast South Dakota...Western and Southwestern Minnesota Concerning...Severe Thunderstorm Watch 536... Valid 150937Z - 151130Z The severe weather threat for Severe Thunderstorm Watch 536 continues. SUMMARY...An isolated severe threat may continue for a couple more hours. Isolated severe gusts and hail will be the primary threats. Watch issuance is not expected to the southeast of WW 536. DISCUSSION...The latest mosaic radar imagery shows a cluster of strong thunderstorms from far southeast North Dakota into southwest Minnesota, which is located along the eastern edge of a moderately unstable airmass. The activity is being supported by a subtle shortwave trough over the northern Plains, and by a 30 to 40 knot low-level jet over central and northeast South Dakota. As the storms move southeastward across western Minnesota over the next few hours, an isolated severe threat should continue. However, instability is considerably weaker over southwestern Minnesota, suggesting that the overall intensity of the cluster should gradually decrease as daybreak approaches. ..Broyles.. 07/15/2024 ...Please see www.spc.noaa.gov for graphic product...
