GOES-14 was in SRSO-R mode on 23 April – 24 April 2016, providing 1-minute Visible (0.63 µm) images (above; also available as a large 115 Mbyte animated GIF) which showed the development of convection over far northern Utah/Colorado, much of Wyoming, southern Montana, and far western South Dakota during the daytime hours of 23 April. Some of this convection produced moderate to heavy rainfall (and some accumulating snowfall) across Wyoming and southern Montana.

Hat tip to Jim Strain, who sent out the Tweet:

Taking a closer look at the Black Hills of South Dakota with GOES-14 Visible (0.63 µm) and Shortwave Infrared (3.9 µm) images (below; also available as a large 151 Mbyte animated GIF), one can see intermittent smoke plumes from the Storm Hill Fire (located near the center of the red circle) on the Visible images during the late afternoon and early evening hours, with the continuation of a fire “hot spot” signature (dark black to yellow color enhancement) on the Shortwave Infrared images into the nighttime hours. The maximum shortwave IR brightness temperature was 324 K at 0424 UTC (10:24 pm local time); the fire hot spot became obscured by dense cloud cover after about 0600 UTC. Highways are plotted in dashed magenta lines on the images.
