About 2 hours after the heat burst event, a comparison of AWIPS images of 1-km resolution POES AVHRR 10.8 \u00c2\u00b5m IR and 3.7 \u00c2\u00b5m shortwave IR data (below)<\/strong><\/em> continued to show an area of slightly warmer surface IR brightness temperatures (20.0\u00c2\u00ba C and warmer, yellow color enhancement)<\/em> along the rear flank of the collapsing convection. Again,\u00c2\u00a0 the areal coverage of the warm signature was greater on the 3.7 \u00c2\u00b5m shortwave IR image, since that channel is more sensitive to warmer temperatures.<\/p>\n
