GOES-14 Super Rapid Scan (1-minute interval) images of eastern US low-end derecho
For the second consecutive day, the GOES-14 satellite was placed into Super Rapid Scan Operations for GOES-R (SRSOR) mode to monitor the ongoing severe bow echo/low-end derecho event that was moving across the eastern US on 13 June 2013. GOES-14 0.63 µm visible channel images at 1-minute intervals (above; click image to play animation; also available as a QuickTime movie) revealed the emergence of a well-defined shelf cloud across Virginia and North Carolina, which marked the leading edge of the gust front moving out ahead of the line of severe thunderstorms. According to the SPC storm reports, these storms produced a wide swath of damaging winds (with gusts as high as 78 mph in Virginia), along with some large hail (up to 2.75 inches in diameter in Maryland).
