The top image below is SRSOR Visible at 1820UTC. The second image is regular GOES Visible at 1745UTC. There was a lot of useful information available in the rapid scan in between regular GOES scans (in this case 45 minutes between images in AWIPS). The Rapid Scan showed clearing skies south of a cold front  and west of a weak surface low. Briefly following clearing the rapid scan clearly showed growing cumulus/convective initiation along the lines with scalloped area below.   Details of individual cloud elements (including tops quickly blowing off with initial convection) was very obvious in the rapid scan.

While regular GOES imagery reflected the general trends on a larger scale, it did not reflect the extent of clearing skies or convective growth. Evolution on the storm scale is not evident.
