.\ , . , ."') , By 9:30 p.ro. a large storm compl~x, which had formed earlier in northeast Colorado, was near Arapahoe and moving southeasterly toward Greeley County. S$eding began 10:31 p.m. with all aircraft concentrating on it. There were multiple cells within the largQ complex, aome of which were located behind the primary area of seeding and throwing hail into area$ where seeding or.dinarily would have been performed. The storm moved from SQllthwest Greeley across Syracuse doingO devastating hail damage, then furthar southeast across southeastern Hamilton, southWestern Kearny, northwestern, central and southeastern Grant, and southwest Haskell. As seeding finished around Grant and Haskell counties between 1: 02 and 1:1' a.llI. (June 10th), aircraft were low on seeding agent and fUEll. During this period of seeding this large complex of storms, other severe storms built in eaatern Hamilton and western Stanton counties. The western Stanton storms WeL~ dttenuated on radar and not identified as strongly hail producing at the time. The Stanton storms passed southeast and may have bean r.Gspon3:1.ble for the large hail reports later in Liberal. Two a.ircraft were building in southwest unsuitable for seeding flight time for the day scrambled at. :3: 18 a. m. for new storms Greeley County, however, clouds werQ and the flights were terminated. Total was 32.0 hourll June 10th/ 11.th =-9EE~.J'_1Q~t.~._ P-!\YS /tp / # 1~: Mid-afternOon severe thunderstorms began forming in northeast Colorado; all available planes were scrambled at 2:48 p.m. When saeding began at 3:32 p.m., the oore of the storm was 10 miles northwest of Sharon Springs and rooving southeaaterly. The storm entered the target area around 3:010 p.m. All aircraft seaded the storm as it moved southeast except for the cloud top aircraft. Air traffic control would not allow the aircraft to work outside of a 60 mile radius of Garden City due to nl-illtary llU!neuversof some sort. So, the cloud top plane had to wait for a.lmost a half-hour until the storm llIoved closar. A hail streak about a half-mila wide was noted on the ground across northwest Greeley County and into Wallace County. This storm was slnd.lar to othe.t' vBt:yl.=irge storms in that th9ro were mult:lple cores within the complex producing hail, BOml!! of which could not be saed~d because of their position within the storm oomplex. The complex began weakening around 5 p.m. and by 5:43 p.m. the storm had all but diss.i.pated so that all planes were able to terminate their flights. Skies cleared afterward. Later in the evening, around 10:55 p.m~, planes were again scrambled to a rapidly building group of storms building in eastern Colorado, adjacent to Grgeley County. During the next seven hours new savere storms development seemed chaotic ~s they built randomly over Greeley, Hamilton, Grant, Kearny, W.ichita and Finney countiea. Seeding began at tl:30 p.m. in Greeley County and continued over all the previously roentioned counties until 5:57 a.m., Jun$ 11th. Total flight time for the day was 23.4 hours.
