AWIPS images of the GOES 10.7 \u00c2\u00b5m IR channel (above)<\/strong><\/em> showed the development of severe thunderstorms across parts of Colorado, Wyoming, Nebraska, and Kansas on 22 May 2008<\/a> <\/strong>(<\/em>see also:<\/em> CIRA RAMMB Satellite Case Study<\/a><\/em><\/strong>)<\/em>. According to the SPC storm reports<\/strong><\/a>, a number of tornadoes were produced by these storms (one tornado-related fatality was reported near Greely, Colorado), along with large hail (up to 2.75 inches<\/strong> in diameter near Windsor, Colorado and 3.00 inches<\/strong> in diameter near Grinnell, Kansas).<\/p>\n

\"MODIS<\/a><\/p>\n

A closer view using the 1-km resolution MODIS 11.0 \u00c2\u00b5m IR channel (above)<\/strong><\/em> from around 17:57 UTC (11:57 am local time)<\/em> revealed a rather diffuse “enhanced-v” signature<\/strong> just east\/northeast of Fort Collins, Colorado (station identifier KFNL)<\/em>. This storm went on to produce tornadoes and large hail in southeastern Wyoming, with one tornado doing extensive damage in the Laramie area.<\/p>\n

Another MODIS IR image from around 19:34 UTC (1:34 pm local time) <\/strong><\/em> displayed impressive detail in the overshooting top structure of the storms developing over western <\/strong><\/em>Kansas and far southwestern Nebraska (below)<\/strong>,<\/em> with the coldest cloud top brightness temperatures in the -70\u00c2\u00ba to -80\u00c2\u00ba C range (black to while enhancement)<\/em>.<\/p>\n

\"MODIS<\/a><\/p>\n

The GOES sounder derived Convective Available Potential Energy (CAPE) product (below)<\/strong><\/em> indicated that the pre-convective environment across northeastern Colorado during the morning hours was becoming unstable, with CAPE values in the 2000-4000 J kg-1 range (yellow to red enhancement)<\/em> at 16:00 UTC (10 am local time)<\/em>. The air mass south of the warm front and east of the dryline (from southern Kansas into Texas) was also very unstable, with CAPE values in some areas over 4000 J kg-1 (purple enhancement)<\/em>.<\/p>\n
