As the line moved eastward rapidly (around 45 to '.' 50 mph), the individual 'storms in the line moved southeasterly. Seeding began in Greeley County, Beat of Towner, co at 7:33 p.lll., eventu8,lly lj!nding up with.,.three aircraft seeding north-south a~:ross' Greeley and Wallaqe counties. The last plane seeded in northern Hamil ton County beqinning at 7:54p.m. As seeding was progressing gUSt fronts were being pushed out strongly to the east all along the line at one time or another. , The plane seeding in northern Hamilton WaS moved south along the leading edge of the line arriving in western Stanton County at 8:28 p.m. After seeding over Stanton and Grant counties tl1e seeding aircraft moved northward into Kearny County to assist the three other aircraft---the three other planes had been following the line eastward and had been directed to concentrate mostly in NW K9arny and .sou-tharn. ~':1ch1ta counties. Severe 1;hundorstorrn~ .brought strongly wind (64 mph-maximum) driven small hail and moderate rain to the radar site. All aircraft continued seeding the line over Finney, Gray, Haskell and Ford counties unt.1.1 the storm system showed signifioant weakening, around 10:25 p.m., at which time all flights were terminated. Total flight time on this operation was 15;6 hours. JULY 13th114th - OPERATIONAL DAYS #29/30: A few thunderstorms built in eastern Colorado during the afternoon and moved easterly toward Kansas. A cold front alao passed through during the evening. As the storms moved closer to the state line new storm growth increased, forming a north-south oriented line as it moved into Kansas. Three cloud base planes were initially scrambled at 9:35 ~.m. to meet the ~rimary storm developing near: Holly, CO, but collapsed shortly a(~erward. The remaining two planes were scrambled at 9:50 p.m. as significant, strong new cloud growth occurred in west-central and northwestern Stanton County. Seeding beqan at 10:04 p.m. in south~rn Hamilton and western stanton with three aircraft focusing work there. The fourth cloud base plane worked over northern Hamilton County.. The cloud top aircraft began seeding over northeastern Hamilton at 10:52 p.m. and worked north-south along the line of storros...,..which-h;ofl "'T:'a~nized by, that time seeding. from Qreeley County across Hamilton and Stanton, then back across Grant, Kearny and wichita counties. All aircraft stayed in front of the eastedy-moving line as it moved into the central patt of the target area and seeded north to south into the front-feeding ~pdraft areas of that line. Initially, seeding was to reduce haili however, by 11:50 p.m. storm intensities and updrafts had decreased to levels low enough so that rainfall stimulation could be continued over a larger area beginning at 11:50 p.m.. The flight of the cloud top aircraft was terminated' at 11:35 p.m~ Seeding to increase rain was performed across southern parts of Scott and Lane counties, Finney, Haskell, Gray and western Ford County. Other aircraft flights terminated'at 12,08 a.m., 12:22 a.m., 12:37 a.m. and 2:01 a.m. Total flight time on this operation was 19.3 hours. '
