<br />storm,episode prior to frontal passage this. day. At 12:57 a.m. one <br />plane was scrambled to an E-W line of storms across Stevens County; <br />two other planes were scrambled at 1:13 and 1:17 a.m. Hail was <br />indicated by radar in NE Morton County. Seeding began for hail at <br />1:22 a.m. on the line south of Big Bow in Stanton County. Storms <br />were moving to the ENE into Stanton and Grant counties. Seeding <br />continued until 1:47 a.m. when we switched to rainfall augmentation <br />because of lower updrafts and lower radar intensities. All seeding <br />ended at 1:52 a.m. and all aircraft returned to their bases, two of <br />them not having seeded. <br /> <br />Around mid-afternoon clouds developed in an E-W line, west of <br />NE Kearny; two planes were scrambled to increase rainfall, one at <br />2:39 p.m., the second at 2:45 p.m. Seeding began at 2:59 p.m. in SW <br />Lane County and in the Kearny/Finney area at 3: 11 p.m. Another <br />plane, scrambled at 3: 02 p.m. An"a-wide storm intensifica'tio:1 <br />ensued such that by 3:32 p.m. hail suppression had to be started in <br />northern Kearny. Other planes were scrambled at 3:58 and 4:02 p.m. <br />Seeding proceeded on storms from near Kendall across central Kearny <br />into central Finney counties. As storms "pulsed", losing severe <br />intensities, rain stimulation continued. One plane had to land for <br />fuel at 5:22 p.m., the same time that a new seeding area for hail <br />was begun in western Greeley County. A funnel cloud was seen near <br />Tribune around 5:43 p.m. The cloud top plane began working in that <br />area at 5:35 p.m. In southwestern Finney County and near Deerfield <br />hail was observed at 5:52 p.m. and in SE Lane County at 6:07 p.m. <br />At 6:07 p.m. the cloud top plane was sent to seed over Finney and <br />Gray counties with the other aircraft until it ran out of dry ice <br />at 7:11 p.m. It was airborne again by 8:04 p.m. The cloud base <br />plane in Greeley worked southeast across 'Hamilton County into <br />Kearny before having to land for resupply at 7:29 p.m. It was again <br />airborne at 8:25 p.m. and went to a separate severe storm which had <br />moved from Hamilton County across southern Kearny into NE Grant. <br /> <br />By 8:35 p.m. all seeding was concentrated in <br />and Gray counties ending in Haskell at 9:37 p.m. <br />plane ended at 9:43 p.m. <br /> <br />JUNE 2nd - OPERATIONAL DAY #15: A severe storm built a few miles <br />southeast of Lakin shortly before midnight, June 1st, triggering <br />the scramble of two planes. Seeding for hail began at 12:12 a.m. 12 <br />miles southeast of Lakin. Intermittent rainfall augmentation was <br />performed during the seeding period. Some brief hail fell at the <br />radar site at 12:50 a.m. but by 1:28 p.m. storm intensities and <br />tops were lower and all seeding ended. <br /> <br />Grant, Haskell <br />The cloud top <br /> <br />A few hours later a very fast-moving, large severe storm <br />within a NW-SE oriented line of storms formed and moved into the <br />northwest part of the target area. Planes were scrambled at 5:15 <br />a.m. with seeding beginning at 5:22 a.m. in NW Kearny County. All <br />planes continued seeding ahead of the storm system as it moved <br />southeasterly over portions of Grant, Haskell, Finney, Gray and <br />Ford counties. Seeding ended at 7:46 a.m. <br />
