29 April 2017 -- Severe flooding hits Missouri?

Life-threatening flooding his southeastern Missouri on 29-30 April 2017. (Link for Totals) This lab shows you ABI Infrared Window (11.2 um) and Visible Imagery (0.64 um) as well as Lightning Data from the GLM and from surface-based observations:

Animations of lightning -- These both cover only 10 seconds! But look how much electrical activity is captured -- and look at how much moreareal extent is there in GLM vs. the ENTLN!! This is a series of images that are in the animations above. But maybe those animatios are too fast for you to view. Note how the cooling of the cloudtops is preceding the GLM observations. For lightning to occur, there must be sufficient glaciation to allow for charge separation. Here's a second set of images. Word Doc with Discussion/Questions.
