532 ACUS11 KWNS 171246 SWOMCD SPC MCD 171245 MIZ000-WIZ000-MNZ000-171415- Mesoscale Discussion 1299 NWS Storm Prediction Center Norman OK 0745 AM CDT Mon Jun 17 2024 Areas affected...Western/northern Wisconsin to Upper Michigan Concerning...Severe Thunderstorm Watch 427... Valid 171245Z - 171415Z The severe weather threat for Severe Thunderstorm Watch 427 continues. SUMMARY...At least isolated severe storms, capable of damaging winds and possibly some hail, will continue to focus across west-central Wisconsin through mid-morning, and may spread into additional parts of central/northern Wisconsin, where an additional Watch could be needed. Severe Thunderstorm Watch 427 continues until 15z. DISCUSSION...A relatively small-scale quasi-linear cluster remains strong/severe this morning as it approaches the I-94 corridor of west-central Wisconsin including the Eau Claire area. This cluster will likely continue northeastward, favoring the instability gradient that extends across southwest/west-central Wisconsin toward northeast Wisconsin and the eastern Upper Peninsula of Michigan. This cluster has a general history of severe-caliber wind gusts in the predawn hours, including a measured 53 kt gust at Rochester Minnesota. An additional Watch could be warranted for portions of central/northern Wisconsin pending short-term convective trends. ..Guyer.. 06/17/2024 ...Please see www.spc.noaa.gov for graphic product...
