<br />., <br /> <br />County., Seeding began near the eastern border of Stevens at 6:32 <br />p.m., unable to arrive prior to the hail-producing first entering <br />the county. Seeding continued on the Stevens storms until 6: 48 <br />p.m., by which time the storm cluster had moved northeast out of <br />Stevens into Seward County, a non-target area county. The seeding <br />plane then flew to the Lakin area for seeding on a new N-S oriented <br />line of storms. It looks as if the old N-S surface trough had <br />continued drifting east with time such that by 6:41 p.m. storms <br />began forming and intensifying over its boundary'once more to form <br />a N-S line across eastern portions of Wichita, Kearny and Grant <br />counties. Seeding began just northeast of Lakin at 7:06 p.m. <br /> <br />Moving back in time a bit, the cloud top aircraft was moved <br />out Of the Wallace County'area at 6:25 p.m. and sent to "an isolated, <br />storm in, <.:entral Wichita County ,and,' Eventu".Dy t,.." wot.kthe newly <br />forming N-S line developing from Wichita County southward. After <br />flying one pass south along the line, the cloud top plane had to <br />land for fuel. At 6:48 p.m. one of the seeding planes had to land <br />for fuel and supplies---itwas airborne again at 7:58, p.m. and <br />seeding near Lakin at 8:15 p.m. - <br /> <br />By 7:30 p.m. the north-south line of storms on the surface <br />trough was strongest from Deerfield north along the FinneY/Kearny <br />county and Scott/Wichita county lines with a separately intense <br />area along the cold front in northern Wichita County and both areas <br />were being seeded. In the sector between the trailing edge of the <br />cold front, moving easterly from Western Kansas and converging with <br />the surface trough, new storms built quickly. Seeding was performed <br />by all available planes around the surface trough-formed storms, <br />however, two aircraft had to land for fuel and/or supplies; one at <br />7:38 p.m., the other at 7:49 p.m. One of the planes were able to <br />get airborne a second time, at 9:34 p.m. and CBgin seeding at 9:51 <br />p.m. in southern Lane County. <br /> <br />By 9:50p.m. the storms generated along the cold front had <br />overtaken those generated around the surface trough forming a <br />massive, area",of thunderstorms,' and rainshowers in Scott County and <br />-portions of Kearny.,Finne:y; wic:hitaand 1.ane counties. When seeding <br />ended at ,9:05 p.m, three of the aircraft were working in Lane <br />County and one had been working in eastern Kearny/western ,Finney. <br /> <br />~ s~:~ <br /> <br />program Manager, <br />Western Kansas Weather Modification <br />
