September 2018 GOES-16 RGB Composite
I created a True Color RGB image for all GOES-16 data files between 1800-1820 UTC for the month of September 2018. Then I plotted an image for different RGB percentiles. Looks cool.
Notice the differences between the 0th (minimum) and 1st percentile. Those dark spots are caused by cloud shadows.

Summer 2018 Lightning Flashes
The Geostationary Lightning Mapper (GLM) observed about 150 million lightning flashes this summer between 8 May and 7 September, 2018.
There is an odd straight line to the east of Florida and one across South America. These are caused by a known processing issue of the GLM instrument and will be fixed soon.
Below shows the no-flash/flash mask. In other words, the pixel is green if there was any lightning flashes ever observed during the period. In this figure, you get a sense of the area the instrument is able to observe in.

Coal Hollow Fire
The Coal Hollow fire, 10 minutes up Spanish Fork Canyon, was started by lightning on August 4th and has burned over 6,000 acres.
The plume of smoke and a pyrocumulus cloud has been visible for the last few days.
The smoke and fire temperature shows well in GOES-16 observations:
The air quality in Spanish Fork this morning (August 9, 2018) is extremely bad. I ride the train with
my dad and he had a hint smelled of smoke on his clothes.

The Red Narrows weather station up Spanish Fork Canyon shows the shift in wind down the canyon last night.
And here are the winds at UKBKB (EW2355)

Quarter-Sized Hail
Quarter-sized hail was observed in this quick-moving thunderstorm that moved across the Salt Lake Valley before noon...
It looks to me that the lightning data is skewed a little south of there it actually occurred. The center of maximum reflectivity is in the heart of Salt Lake County, but the lightning mapper positioned the flashes along the Salt Lake-Utah county line.
