We can only hope the scientific and technical merits of the <br />request will be considered and not be swayed by political pressures <br />from any source. The longer our weather modification program is in <br />existence, the harder it is to refute the results found, especially <br />when refutation is based upon opini.on and subjectivity instead of <br />upon substantiated data and facts. <br /> <br />OPERATIONS: Generally, the w.."j( Wfl'" dr,y.with successive front;;:l <br />passages bringing either only a wind shift or minimal rainfall from <br />unseedable clouds. By week's end, ,May 3rd, abundant low level <br />moisture had moved in making for high severe storm potential. <br />Although aircraft were scrambled May 3rd, no seeding was performed <br />until after midnight May 4th aDd then only briefly. <br /> <br />APRIL 27th/28th - OPERATIONAL DAYS H & #2: (All times are CDT): <br />Dry weather continued in Western and Southwestern Kansas. However, <br />by Saturday, April 27th, a low pressure center had formed just <br />south of a cold front passing through our area helping to carry <br />moisture and instability into large portions of Kansas east of us, <br />Between 10,35 and 10'4,5 p.m. all aircraft were launched to seed <br />severe thunderstorms which broke out just northeast of Ford County <br />and were propagating to the southwest into Ford County. Storm <br />movements were to the southeast and east-southeast. Radar indicated <br />large hail just outside Ford County (later confirmed that 2" hail <br />fell around Lewis, in Edwards County). <br /> <br />Seeding first began at cloud base in northwestern Ford County <br />at 11:15 p.m. and during the course of the operations seeding was <br />hampered by poor visibility and low cloud bases. A second storm in <br />southwestern Ford was begun tobe seeded at 11: 56 p.m. The 5 cloud <br />b~.~e. .e'.irc"raft were divided bct.....~c~n tho. -. two stollliS, 3 on the <br />northwestern one and two on the southwestern one. The cloud base <br />aircraft seeded both storms, first seeding in northwestern Ford at <br />11:50 p.m. Radar showed hail in the storm being seeded which moved <br />from southwestern Ford into central Ford. By 12:53 a.m. it had <br />moved ENE out of Ford County. The seeded storm in northwest Ford <br />moved easterly into extreme northeast Ford before being let go at <br />,," a.m. and all aeeding .nded~ IJ. ~ <br /> <br /> <br /> <br />Curtis D, Smith <br />program Manager, <br />Western Kansas Weather Modification <br />
