An AWIPS image of the 1-km resolution POES AVHRR 12.0 \u00c2\u00b5m IR channel data (above)<\/em><\/strong> displayed a classic and well-defined example of an “Enhanced-V” storm top signature over the northern Texas Panhandle region on 18 May 2010<\/a><\/strong>. Overlays of SPC storm reports<\/a><\/strong> and cloud-to-ground (CG) lightning strikes near the time of the image showed that this severe thunderstorm was producing hail as large as 2.75 inch in diameter, as well as a couple of tornadoes — and there were a large number of CG strikes within the Enhanced-V signature. The coldest cloud top IR brightness temperature was -74\u00c2\u00ba C.<\/p>\n

The corresponding 4-km resolution GOES-13 10.7 \u00c2\u00b5m IR image (below)<\/em><\/strong> did exhibit an Enhanced-V signature, but the details were not as well-defined at the coarser spatial resolution. The coldest cloud top IR brightness temperatures were also about 10\u00c2\u00ba C warmer on the GOES-13 image.<\/p>\n
