GOES-16 Visible Imagery (0.64) from 1902 through 2307 UTC on 29 June 2017. Woodbury County in Northwest Iowa is outlined in Magenta (Click to play animated gif)
GOES-16 data posted on this page are preliminary, non-operational data and are undergoing testing
Softball-sized hail fell over parts of Iowa on Thursday afternoon, 29 June (Storm Prediction Center Storm Reports). The visible animation above, from 1902 to 2307 UTC, shows the rapid development of convection over far northeast Nebraska. Woodbury County in Iowa is outlined in the animation, the largest reported hail occurred in that county along the shores of the Missouri River; the location of the hail is shown as the green box in this slide. This visible image corresponds to the time of the hail fall.
One of the GOES-16 Baseline Products available to forecasters includes a series of stability parameters derived from the ABI channels (and using GFS data as a first guess): Legacy Atmospheric Profiles (or LAP). (Online Source) These products are similar to those produced from the GOES Sounder on GOES-15. The LAP Lifted Index at 2100 UTC, below, from the GOES-16 Mesoscale Sector sited over the convection, shows a remarkable pool of instability (Lifted Indices less than -8º C) in the region near the developing convection. More information on the Legacy Atmospheric Profiles products is available here (as part of the Satellite Foundation Course for GOES-R).
LAP Profiles can be an excellent tool for situational awareness when convection develops in clear or partly-cloudy regions.
