<br />JULY 6th - OPERATIONAL DAY *38: By 3:50 p.m. a single storm had <br />begun developing vigorously just east of the east-central Ford <br />County. All planes, except one cloud base plane, were scrambled, <br />but it was scrambled at 4:18 p.m. New storm growth was creating 4 <br />storm cluster growing, strongly on its west and southwest side. <br />Seeding for hail began at cloud base at 4:38 p.m. Others joined in <br />at 4:40, 4:53 and 4:58 p.m, The cloud top plane began seeding at <br />5:05 p.m. All cloud base seeding ended at 5:30 p.m. At cloud top <br />seeding was intermittent until 5:51 p.m. when the cells collapsed <br />into weaker showers. Planes began returning to their bases at 5:35 <br />p.m, Some hail sizes (diameters) reported to the National Weather <br />Service falling in east-central Ford were 3/4 inch tol inch. <br /> <br />JUNE 7th - OPERATION~ DAY *39: At midnight all fiv~ clQ~dba~e <br />planes were scrambled to meet an east-southeast moving line' of <br />storms moving into northwestern Wallace County. Seeding began by <br />one plane at 12:29 a.m., others assisted at 12:34, 12:38 and 12:50, <br />respec~ively. Seeding was east-west along the northern part of the <br />County until 1:18 a.m. at which time the hail threat had diminished <br />and storms had moved away out of the ,target area. <br /> <br />Later in the afternoon, a single storm began forming just <br />north of Lane County. At 4:25 p.m. all aircraft were scrambled to <br />the storm, including the cloud top plane. Unfortunately, the on- <br />board radar system of the cloud top plane was inoperative limitinq <br />its seeding effectiveness. Seeding began at 4:55 p.m. Others joined <br />seeding at 5:01, 5:11, 5:18 and 5:26 p,m" respectively. The cloud <br />top plane began seeding at 5:50 p.m. The storm remained nearly <br />stationary and continued growing larger with time developing into <br />a supercell. Then, between 5:37 and 5:44 p,m., it moved 6outh- <br />southeasterly into north-central and central Lane County. Multiple _ <br />distinct hail-bearing cores were observed in northern Lane County <br />on radar at 5:58 p.m. Heavy seeding was performed on it as it <br />moved into east-central Lane. simultaneously" a WNW-ESE oriented <br />line of severe storms were building on the edge of northeastern <br />Wallace County, running ESE across northern Logan and northern Gove <br />counties. Two planes 'tlere sent in for resupply and' fuel at 7; 13 <br />p.m. By 7:20 p.m. the heavily-seeded supercell was considerably <br />weaker, indicated fewer hail-cores and had moved into east-central <br />Lane near the county line. Then, the three cloud base planes which <br />were seeding it were sent to work east-west along the line just <br />north of the target area counties of Wichita, Scott and Lane. The <br />cloud top plane continued mopping up the Lane stOrIn, seeding <br />intermittently until 7:24 p.m, <br /> <br />At 7:32 p.m. these three remaining planes began concentrating <br />on the part of the E-W line of storms from southwest Gove west into <br />southeast Logan, north of Lane and Scott counties. At 7:36 p,m. one <br />plane ran out of'seeding agent in one of its generators; at 7:50 <br />p.m. its second generator was dryas well. Another plane was down <br />to one generator at 8:05 p.m. High radar reflectivities were seen <br />at 7:40 p.m. in northern Wallace County, but could not be responded <br />to due to reduced seeding capability, <br />
