ZCZC SPCSWOMCD ALL ACUS11 KWNS 140556 SPC MCD 140556 WIZ000-MNZ000-140700- Mesoscale Discussion 1608 NWS Storm Prediction Center Norman OK 1256 AM CDT Sun Jul 14 2024 Areas affected...Southeast Minnesota...Western Wisconsin Concerning...Severe potential...Watch possible Valid 140556Z - 140700Z Probability of Watch Issuance...60 percent SUMMARY...An isolated large hail and wind damage threat may continue for several more hours across parts of southeast Minnesota into western Wisconsin. A new weather watch to the southeast of WW 528 will likely need to be considered. DISCUSSION...The latest hi-resolution radar imagery from Minneapolis shows a cluster of strong to severe storms over southeast Minnesota and western Wisconsin. Most of the storms are multicells, although a supercell is ongoing just to the northwest of Minneapolis. These storms are located along an gradient of moisture and instability that is oriented from north-northwest to south-southeast in the vicinity of Minneapolis. The storms are likely being supported by a minor shortwave trough that is moving through the upper Mississippi Valley. In addition, a maximum in low-level flow is analyzed just to the west of this cluster. The latest WSR-88D VWP at Minneapolis has 0-6 km shear near 50 knots with about 20 knots of speed shear from the surface to about 4 km AGL. This, combined with the moderate instability, should continue to support a severe threat over the next several hours. Isolated large hail and wind damage will be the primary threats. ..Broyles/Edwards.. 07/14/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ARX...MPX...
