On the morning of 30 June 2017, an undular bore is observed in north Texas.  The clouds associated with the undular bore can be seen on the GOES-16 visible (0.64 micron) band.  The GOES-16 Split Window Difference (10.3 – 12.3 micron) product adds additional information.  The undular bore is observed to exist further west of where clouds associated with the undular bore (in clear skies) are located.  We observe this feature in the split window difference due to local maxima in water vapor depth along the “crests” of the undular bore.
