Valid 210046Z - 210215Z The severe weather threat for Severe Thunderstorm Watch 607 continues. SUMMARY...Severe hail remains a concern with the stronger sustained supercells this evening. DISCUSSION...Multiple sustained supercells have progressed across central MN over the past few hours, with marginally severe hail reported (particularly with the storms over northern MN). 2000-3000 J/kg MLCAPE remains in place, along with 35-40 kts of effective bulk shear per 00Z mesoanalysis. The 00Z MPX observed sounding also shows a hodograph with appreciable low-level curvature and modest elongation, suggesting that supercells will remain the dominant mode of the convection through the evening hours. Large hail should remain the primary threat, though a damaging gust or tornado cannot be ruled out. ..Squitieri.. 08/21/2026 ...Please see www.spc.noaa.gov for graphic product...
