<br />Ther~ was a scramble for potential rainfall augmentation <br />at 5:18 p.m. in Oklahoma but was canceled at 5:33 p.m. <br /> <br />JUNE 3rd - OPERATIONAL DAY *16: A weak frontal boundary lay N-S in <br />Western Kansas and the Oklahoma Panhandle this day. By 12 noon the <br />first plane was airborne and did some rainfall stimulation briefly <br />near Garden City 12:16 - 12:20 p.m. A very strong new storm built <br />near Walsh, Colorado, and the airborne plane was directed toward <br />that area anticipating it would move easterly into Stanton County. <br />Other planes scrambll:d at 12:48 p.m. with seeding beginning in <br />southwest Stanton at 12:56 p.m. Three more planes joined at 12:59, <br />1:23 and 1:47 p.m., respectively, and the cloud top joined at 1:38 <br />p.m. and seeded over parts of Stevens, Grant and Haskell counties. <br />After some needed maintenance, the last plane launched at 1:47 p.m. <br />and ,joined in seeding first over Kearny at 2:14p.m then moving <br />into Grant and Stevens counties as the storm complex moved ENE from' <br />Stanton County. At 3 p.m. the cloud top plane returned to Dodge <br />City for fuel and dry ice. After running out of supplies, one plane <br />ended seeding at 3:36 p.m.; two more ended at 3:44 p.m., a 4th at <br />3:46 p.m., and the last one at 5:51 p.m. <br /> <br />The cloud top plane was airborne again at 3:46 p.m. and <br />seeding south of Lakin at 4: 22 p. m. Other new storms began to <br />intensify vigorously near Syracuse soon reorganizinc;r with the <br />storms in Kearny County to become a large NW-SE line of storms. One <br />aircraft left the storm being worked much weaker---it had moved <br />through Stanton, Grant and Gray counties into southwestern Ford <br />County. All planes were brought to the new line of storms to work <br />around the multiple cells in it capable of producing hail. Also, <br />within the line of storms in Hamilton County was one area which was <br />less well-visible and less well-seeded which quickly strengthened <br />to become supercell variety; it moved southerly into central and <br />southeastern Stanton County causing extensive wind-and hail damage <br />to crops in that area. By 6:15 p.m. the cloud top plane had run out <br />of dry ice once again. Seeding continued until the storm had moved <br />into northeastern Morton where it dissipated. Seeding ended at 6:48 <br />p.m. and at 6:56 p.m. all patrolling ended as did operations. <br /> <br />JUNE 4th - OPERATIONAL DAY #17: By 4:29 p.m. an E-W line of <br />towering cumulus and thunderstorms forming across southern Gray and <br />Ford,counties. New cell propagation was to the north, on the "back <br />side" of the line. The two flights which were scrambled were <br />canceled at 5:15 p.m. when the line collapsed and moved out of the <br />target area. <br /> <br />Later a large, but weak, storm cluster moved southeasterly <br />from eastern Colorado into western Hamilton and western Greeley <br />counties. All planes were scrambled beginning at 7:02 p.m. because <br />of the warmer temperatures and higher concentration of moisture <br />available to the storm in the area being moved into---dew points <br />were in the high 50s and low 60s. <br /> <br />precautionary seeding began at 7:26 p.m. Three cloud base <br />planes seeded for hail suppression until 7:50 p.m., however, the <br />
