<br />June 10th/11th - Northern Target Area: Five cloud base-planes and the cloud-top plane were <br />launched at 9:02 p.m. on the 10th toward a eastward-moving line of severe storms in Eastern <br />Colorado. Two cloud-base planes began seeding for hail northwest of Burlington, CO at 9:53 <br />p.m. and a third at 10:15 p.m. The fourth and fifth planes began seeding the line at 10:22 and <br />10:43 p.m., respectively; the cloud-top plane began at 10:51 p.m. As the storm moved into <br />Kansas' Sherman County, weather conditions for flying at cloud-base became too poor to <br />continue and all such flights were terminated at 11 :05 p.m. However, cloud-top seeding <br />continued through central Sherman County until 12:30 a.m., June 11th, at which time it landed to <br />replenish its dry ice supply and refuel. Hail up to 23/4" in diameter and flooding was reported in <br />Kit Carson County, Colorado. Initial reports of hail sizes up to 1 3/4" were reported in Sherman <br />County as well as 60-70 mph surface winds. <br /> <br />NOTE: 766 hail-claims were received during the above period <br /> <br />June 30th/July Ist - Northern Target Area: Three planes were launched at 8: 12 a.m. to a <br />severe storm near S1. Francis, in Cheyenne County. However, low cloud ceilings forced them to <br />land in Goodland with no seeding being performed. Hail sizes of3/4" - 7/8" were reported with <br />another of 1 3/4" and massive crop damage outside the target area during this time. <br /> <br />At 1 0: 12 a.m. the cloud-top Cheyenne was scrambled to a severe storm in Thomas <br />County. Simultaneously, cloud bases had lifted enough to launch two planes from Good1and. The <br />cloud-top plane began seeding over northern Thomas County at 10:38 a.m.; cloud base seeding <br />began in the same area at 10:35 and 10:45 a.m., respectively. The two cloud-base planes seeded <br />until flying conditions deteriorated, landing in Oakley at 11 :08 a.m. However, the cloud-top plane <br />continued seeding until storm intensity dropped below our hail threshold at 11: 15 a.m. <br /> <br />At 1 :26 p.m. six planes were sent to seed a southeasterly-moving supercell near Brewster <br />in western Thomas County from which a tornado was reported some 25 minutes later. The first <br />aircraft began seeding for hail at 1 :36 p.m. in eastern Shennan County and was joined by the <br />others at 1:58, 2:02, 2:10, 2:14 and 2:25 p.m. Seeding followed the storm through southwest <br />Thomas County into Logan County where at 4:47 p.m. operational control was passed on to <br />Lakin Radar. Another tornado sighting was posted 9 miles SSW of Russell Springs. <br /> <br />Southern Target Area: Between 2 - 2:15 p.m. two of the aircraft which had not been sent to the <br />northern target area earlier were airborne heading to an E- W oriented severe storm in southeast <br />Wallace County where seeding began at 2:31 and 2:43 p.m., respectively. All the other aircraft <br />were seeding a tornadic supercell moving into Logan County. The supercell and the Wallace <br />storm eventually merged into a single storm and pushed further southeast across Wichita, Scott, <br />northeast Kearny and Finney counties with all 9 aircraft seeding it. A tornado was reported 8 <br />miles south of Marien thai in eastern Wichita County and cloud rotation was sighted in northwest <br />Finney CountY until near cloud collapse south of Holcomb where seeding finally ended at 5:43 <br />p.m. <br /> <br />29 <br />
