AUGUST 10th + OPERATIONAL Di\Y 1/43: Surface troughing, intene8 heating and high moisture COmbined to trigger severe storms late this afternoon. All cloud base plan6B ware scrambled at 6 p.m. to a severe storm developing in southeast Greeley County laying within an extensive NE-SW line frOM near Leoti to near springfield, CO. Storm movements were very slow to the "outheast or, in someca88s, nearly stationary. Seeding for hail began in northeast Hamilton at 6;37 p.m. As the storm built westward across northern Hamilton . County, it was seeded by three cloud base aircraft; the fourth flew to check out other storms in Greeley County. The cloud top aircraft was scrambled at 6;40 p.m. when storm numbers and intensities were apparently inoreasing over much of Western Kansas. As seeding was ending in northwest Hamilton, planes were divarted to a major ~torm developi~g a few miles south or Laot!; seeding began on it at 7;03 p.lli. - and the others joined shortly afterward. The cloud top aircraft also began seeding the Wichita County (Leot1) storm at 7:30 p.m. and performed other seeding 1n southwestern Greeley County and north+central Hamilton County. As .eedlng waned on the tecti and Hamilton storms, aircratt were moved toward another severe storm growing 1n northeastern Scott County and beginning seeding on it at 8:01 p.m. Thereatter, a gradual tilling in occurred in the cloud gap between the wichita area of storms and the Scott County storms. All planes performed seeding on these two areas and in between them as they grew together. Seeding continued until 9:33 p.m. at which time cloud base updrafts. bedame much weaker and 9"neral cloud development became significantly les9. Flight time amounted to 17.6 hours. AUQUST 13th - OPERAT~ONAL DAY 144: A Canadian cold front mov~ rapidly southward through Western Kansas in late afternoon triggering thunderstorms in Lane County. All planes were scrambled at 5: 50 p. m. when radar indicated an intense new storm complex forming south of a storm area being watched which was much further north, outside the target area. The new storm complex was about 10 miles north or Dighton and slow-moving to the southeast. The first cloud base plane began aeading cot 6: 23p .lit.; the second at 6:38 p.m. As the other planes were heading toward Lane County, other new storms developed in northern Wallace County and were moving southeasterly. Two planes were diverted to Wallace with the first one beginning seeding at 6;46 p.m.; the second patrolled the storm for a short while before going into Logan County to check on an WNW~ESE line of storms QX~andin9 down into Scott county. ~9 cloud top aircraft began seeding the Lane County storms. at 7:03 p.m., working around the extreme northeast corner as well as the eastern-central part of it before the cells moved east out of the target area. The cloud top plane checked out the line of storms over Logan County extending into NW Scott and terminated at 6:43 p.m. shortly after taking a lightning str1ke. Later the it was found the lightning strike cau~ed some damage to the aircraft, however, it WAS flyable by the next day.
