Mesoscale Discussion 1626 NWS Storm Prediction Center Norman OK 0236 AM CDT Mon Jul 15 2024 Areas affected...Central and Southeast North Dakota Concerning...Severe Thunderstorm Watch 536... Valid 150736Z - 150930Z The severe weather threat for Severe Thunderstorm Watch 536 continues. SUMMARY...A threat for large hail and severe gusts will continue to be possible for at least a couple more hours across parts of central and southeastern North Dakota. DISCUSSION...The latest mosaic radar imagery shows an MCS across central and southeastern South Dakota, where a cluster of strong to severe storms is ongoing. The cluster is located along a northwest-to-southeast gradient of moderate instability extending across central and southeastern North Dakota. The storms are being supported by large-scale ascent associated with a subtle shortwave trough, evident on water vapor imagery. The latest WSR-88D VWP at Bismarck has 0-6 km shear near 70 knots, owing mostly to strong speed shear in the lowest 6 km. This is expected to support continued cell organization within the MCS over the next couple of hours. Large hail and isolated severe gusts will be the primary threats. ..Broyles.. 07/15/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FGF...ABR...BIS...
