\"GOES-14<\/a>

The GOES-14<\/strong><\/a> satellite continued to be in Super Rapid Scan Operations for GOES-R (SRSOR<\/strong><\/a>) mode on 11 May 2014<\/strong><\/a>, capturing the development of thunderstorms along a dryline that stretched from the Texas Panhandle into far southwestern Kansas. As a southward-moving cold front intersected this dryline, McIDAS images of 1-minute interval GOES-14 0.63 \u00b5m visible channel data (above; click image to play animation; also available as an MP4 movie file<\/a>)<\/strong> <\/em>showed that the narrow line of storms later developed into large discrete supercell thunderstorms over Kansas, with widespread reports of tornadoes, large hail, and damaging winds (SPC storm reports<\/strong><\/a>).<\/p>\n

Farther to the northeast, other large supercell thunderstorms could be seen growing over eastern Nebraska along a warm frontal boundary — these storms exhibited numerous signatures of vigorous overshooting tops. Near the end of the animation, winds gusted to 82 mph at Omaha, Nebraska at 00:51 UTC.<\/p>\n

AWIPS images of GOES-13 sounder Convective Available Potential Energy or CAPE (above; click image to play animation)<\/strong><\/em> and Total Precipitable Water or TPW (below; click image to play animation)<\/strong><\/em> with surface frontal analyses revealed the sharp gradient of both instability and moisture across the dryline — just to the east of the dryline, CAPE values exceeded 4000 J per kg (darker purple color enhancement),<\/em> while TPW values were generally in the 30-40 mm or 1.2-1.6 inch range (shades of yellow)<\/em>. In addition, GOES-13 sounder Lifted Index<\/strong><\/a> values were in the -8 to -10\u00ba C range across parts of Kansas into southeastern Nebraska prior to convective initiation.<\/p>\n
