<br />However, while planes were enroute back to their bases, a new
<br />east-west cluster of storms began to appear in northern Hamilton
<br />and 2 planes were diverted to check it out. Hail intensities were
<br />seen on the Hamilton storms by ra.dar at 4: 16 p.m. and two more
<br />planes were scrambled for assistance. Seeding began at 4:26 p.m.;
<br />a second at 4:29 p.m. The cloud top plane was scrambled at 4:37
<br />p.m. but' lacked an, operational on-board radar. When updrafts
<br />weakened for a briefly between 4:40 and 4:48 p.m. rain stimulation
<br />was performed. But, as updrafts increased at 4:48 p.m., seeding for
<br />hail was initiated. A third plane also began seeding in northern
<br />Hamilton at 4:52 p.m. with the storm continuing to indicate it had
<br />hail in it. As the east-west line of storms moved into southern
<br />Greeley at 5 p.m., some new storm growth propagated westward into
<br />Colorado. Updrafts at cloud base abruptly decreased by 5:12 p.m.
<br />and seeding rates were lowered. At 5:24 p.m. all seeding. ~nded on
<br />the storms which, by then, were in Greeley County.
<br />
<br />,More" new storm growth, soon ,began developing"&n',W",,,,,,',,,,,,,C,i'Gt'&eley
<br />County and spread further east across central WiChita, toward Leoti
<br />and Scott city. Seeding began in southwestern and southcentral
<br />Greeley at 5:34 p.m., then on the line east toward Scott County.
<br />Another cloud base pane scrambled at 5:33 p.m. and was assistinq on
<br />the line in western Wichita County by 5:50 p.m. The cloud top plane
<br />also was seeding the east-west line by 5:40 p.m.
<br />
<br />Two isolated st9rms began forming, one about 10 miles west of
<br />Syracuse, the other about 10 north of Kendall; one plane was sent
<br />to one nearer Kendall, at 6:02 p.m. finding nothing, then flew to
<br />the storm west of Syracuse to which a second plane was enroute. All
<br />other planes continued seeding across Greeley and WiChita counties.
<br />Seeding began in western Hamilton County at 6: 11 p.m., the second
<br />at 6:28 p.m. The last cloud base seeder was scrambled at 6:15 p.m.,
<br />shortly before the first plane needing refueling at 6:23 p.m. All
<br />storms were propagating and/or moving northwesterly.
<br />
<br />By 6:41 p.m. the overall storrnipicture had reorganized into
<br />three areas, (1) an east-west line across northwest Greeley, seeded
<br />by two planes, (2) a NE-SW line from northeast Hamilton to Coolidge
<br />and further southwest---seeded by two others, and a weaker, but
<br />intensifying, . east-west line, across central Greeley and, central
<br />wichita counties ,evontually seeded at .6: 58 p.m, by the last plane
<br />scrambled at 6:23 p.m; A gust front was kicked out of the western
<br />Hamilton storm.s, however, it may have been reinforced by a aurface
<br />trough which already had begun a more active movement eastward
<br />which was first detected near the state line at 6:40 p.m. The cloud
<br />top plane had to land for fuel at 7:32 p,m. The first cloud base
<br />plane to land was bacl<: in the air by 6:52 p.m. and seeding in
<br />eastern Hamilton at 7:15 p.m. As the trough moved eastward, it
<br />invigorated new storm growth between all three areas of storms just
<br />mentioned, especially in northwestern Hamilton and southeastern
<br />Greeley where seeding soon became very active. The new storm growth
<br />areas in Greeley and WiChita continued moving northwesterly with
<br />time as the areas themselves merged into a solid area while mOVing
<br />northward (while being seeded); the storm area eventually passed
