Wider weather episode

An area of low pressure lifted a warm front into the Northland during the day on the 26th. Behind this warm front was a moist and unstable airmass and daytime heating led to the development of strong to severe storms over northern Minnesota that moved to the southeast over western Lake Superior during the evening hours. A line of storms that moved along the South Shore produced numerous wind gusts over 40 mph with a peak gust of 62 mph on the Blatnik Bridge in the Twin Ports. The KDLH radar was inoperable for this event but a high level of service was maintained by utilizing the KMPX and KMQT radars and one minute GOES-16 satellite data.
