1-minute SRSO-R GOES-14 Visible (0.63 µm) images (above; also available as a 265 Mbyte animated GIF) showed the development of severe thunderstorms which produced large hail and damaging winds (SPC storm reports) in southeastern North Dakota, northeastern South Dakota and far western Minnesota on 10 August 2016. SPC noted a region of enhanced instability centered over southeastern North Dakota around 16 UTC (MCD); it is interesting to note that an orphan anvil was seen to form around 13 UTC between Valley City (KBAC) and Gwinner (KGWR) — near the northern edge of the pocket of instability — before the main convection began to develop just north of the North Dakota/South Dakota border around 1515 UTC.
