SUMMARY...A corridor of strong to severe gusts around 50-65 mph remains possible this morning across far southeast Minnesota into far northeast Iowa and west-central Wisconsin. DISCUSSION...A cluster of storms near a surface boundary across southeast MN will continue to track east around 40 mph. This activity has produced gusts up to 67 mph recently. The downstream environment remains very moist and unstable, and a southwesterly low-level jet around 25-30 kt should further aid in maintenance for strong to severe convection the next couple of hours as storms approach the MS River. ..Leitman.. 06/17/2024 ...Please see www.spc.noaa.gov for graphic product...
