Mesoscale Discussion 1316 NWS Storm Prediction Center Norman OK 0603 AM CDT Tue Jun 18 2024 Areas affected...northeast MN Concerning...Severe Thunderstorm Watch 432... Valid 181103Z - 181230Z The severe weather threat for Severe Thunderstorm Watch 432 continues. SUMMARY...Strong thunderstorm gusts of 45-60 mph remain possible across portions of northeast Minnesota the next couple of hours. DISCUSSION...An organized line of thunderstorms will continue shifting east across northeast MN the next couple of hours. Measured gusts have mostly been in the 45-60 mph range over the past hour. Moderate elevated instability amid strong vertical shear should maintain thunderstorm intensity for another 1-2 hours. With eastward extent, this activity may weaken as it approaches the MN Arrowhead/Lake Superior where temperatures are cooler and an earlier cluster of thunderstorms has likely modified the airmass, resulting in weaker instability. ..Leitman.. 06/18/2024 ...Please see www.spc.noaa.gov for graphic product...
