A previous blog post discussed the use of GOES-16 1-min VIS and IR imagery during warning operations. Below is an example of a vertically stacked 2-panel display of GOES-16 VIS and IR imagery (and ENI Total Lightning data, warnings) for morning severe storms in the Dakotas. The 2-panel display has proven useful for monitoring convective trends during warning operations alongside radar data, especially with 1-min data. This is especially feasible nowadays with the larger/wider AWIPS displays now in NWS offices. In the example below, persistent storm top bubbling in the VIS along with obvious OT and enhanced V/U in the IR indicate continued strong updrafts. Gravity waves atop the anvil are also noted in the VIS.

The thunderstorm complex maintained its strength as it shifted to the south and east, producing damaging winds along its path.

Why does the IR imagery appear so smoothed spatially? My experience with GOES-16 data suggests a higher resolution appearance
