As noted on the Satellite Liaison Blog, an outbreak of severe thunderstorms developed over parts of Oklahoma and Texas on 26 March 2017. A GOES-16 Mesoscale Sector positioned over that region provided 1-minute data — and 0.5-km resolution Visible (0.64 µm) images (above; also available as a 114-Mbyte animated GIF) showed the formation of storms that produced hail (as large as 3.25 inches in diameter, at 0043 UTC) and one tornado (at 0018 UTC) in eastern Oklahoma during the 2000 to 0045 UTC time period. SPC storm reports are plotted in red — their locations have been parallax-corrected, assuming a cloud top height of 11 km. Both of the aforementioned large hail and tornado events occurred  during the 30-minute gap in operational GOES-13 (GOES-East)  imagery from 0015 to 0045 UTC, when that satellite was executing New Day Schedule Transition and Southern Hemisphere scan duties.
