<\/a>GOES-13 Infrared Window (10.7 \u00b5m) images [click to play animation]<\/p><\/div>4-km resolution GOES-13 (GOES-East)<\/em> Infrared Window (10.7 \u00b5m) images (above)<\/strong><\/em> showed the cold cloud tops associated with training and back-building thunderstorms that produced very heavy rainfall (along with some hail and damaging winds) in parts of Southeast Texas during the 26 May<\/strong><\/a> – 27 May 2016<\/strong><\/a> period. The images are centered on Brenham, Texas (station identifies K11R),<\/em> where over 19 inches of rainfall was reported in a 24-hour period (NWS Houston PNS<\/strong><\/a>). Note the presence of very cold cloud-top IR brightness temperatures of -80\u00ba C or colder (violet color enhancement)<\/em>.<\/p>\n During the overnight hours, a comparison of Suomi NPP VIIRS Day\/Night Band (0.7 \u00b5m) and Infrared Window (11.45 \u00b5m) images at 0801 UTC or 3:01 am local time (below)<\/strong><\/em> revealed cloud-top gravity waves propagating northwestward away from the core of overshooting tops (which exhibited IR brightness temperatures as cold as -84\u00ba C) located just to the west of Brenham. Due to ample illumination from the Moon — which was in the Waning Gibbous phase, at 71% of Full — the “visible image at night” capability of the VIIRS Day\/Night Band (DNB) was well-demonstrated. The bright white streaks seen on the DNB image are a signature of cloud-top illumination by intense lightning activity.<\/p>\n Suomi NPP VIIRS Day\/Night Band (0.7 \u00b5m) and Infrared Window (11.45 \u00b5m) images [click to enlarge]<\/p><\/div>A time series plot of surface weather conditions at Brenham is shown below.<\/p>\n<\/a>
