1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed the development of thunderstorms over southern Wisconsin during the afternoon and evening hours on 16 June 2018. There were reports of hail, damaging winds and 1 brief tornado (SPC storm reports | NWS MKX summary). The pulsing of short-lived overshooting tops is evident in both Visible and Infrared imagery; above-anvil cloud plumes can also be seen in Visible imagery, drifting southeastward from the more robust overshooting tops. Note at 2000 UTC the boundary that was oriented approximately north-to-south, with widespread cumulus clouds to the west and generally cloud-free conditions to the east: this was a lake breeze boundary that had migrated inland from Lake Michigan. Many of the storms appeared to intensify as they interacted with this boundary.Categories: GOES-16, Severe convection
