There was no evidence of either of these linear features in the corresponding GOES-17 Infrared imagery, or in Visible imagery (not shown). A perfect candidate for the “What the heck is this?” blog category.<\/p>\n

One possible explanation for the curious stationary feature was that it resulted from a convergence of flow around the cutoff low to the east and a digging trough approaching from the west. GOES-15 Infrared cloud-tracked Derived Motion Winds from the CIMSS Tropical Cyclones<\/strong><\/a> site (below)<\/strong><\/em> did show evidence of some converging flow in that region. Derived Motion Winds from GOES-17 were still in the Beta stage, and were not available for display in AWIPS.<\/p>\n
