With the arrival of daylight the following morning, 1-minute interval GOES-14 SRSO-R<\/strong><\/a> visible (0.63 \u00b5m) images (below)<\/strong><\/em> revealed the presence of numerous short-lived overshooting tops which were penetrating the cirrus canopy of the persisting MCS. The formation of a well-defined outflow boundary was also seen, which continued to move southward during the late morning hours. The MP4 movie file is also available as a very large (73 Mbyte) animated GIF<\/strong><\/a>. A GOES-14 1-minute-image IR (10.7 \u00b5m) animation which shows the initial development and subsequent motion of the MCS can be seen here<\/a><\/strong>.<\/p>\n
