<br />Hitch Ranch which is located southeast of Guymon. The storms passed <br />the Hitch Ranch relatively quickly to the east. All seeding ended <br />at 9:55 p.m. and flights terminated. <br /> <br />Out of this sequence of storms, the National Weather Service's <br />preliminary reports listed tornadoes occurring east of Ford County <br />in Pawnee County, south of Larned, nearby and inside Mullinville <br />itself (Kiowa County) and near Coldwater (Comanche County). Maximum <br />hail sizes reported to the National Weather Service outside the <br />target area were up to 2 3/4 - 3 1/2 inches in diameter and inside <br />the target area up to 1 1/4 inches. <br /> <br />JUNE 12th - OPERATIONAL DAX #21: By sundown a north-south oriented <br />line of storms was approaching the Kansas - Colorado state line <br />west of Hamilton County, Two severe storms, with hail, were seen on <br />radar in northwest Prowers County (Colorado) prior to scrambling <br />four cloud base planes. The planes were scrambled between 8:44 and <br />9: 14 p.m. The first plane airborne fl~wintc Colorado tccheck out <br />'the storm characteristics (cloud base height, updraft velocity, <br />amount of precipitation, ete. ) then, returned to Kansas. The four <br />aircraft were soon "stacked" vertically along the Ramilton County <br />line seeding to suppress hail. Seeding began at 9:1B p.m. As the <br />line of storm moved nearer they weakened and collapsed, eventually <br />pushing out an extensive, arc-shaped gust front across the entire <br />western portion of the target area, north to south. AS storm <br />intensities lowered, some intermittent seeding was done first to <br />increase rainfall, then to reduce hail, then back to the rainfall <br />stimulation mode---this occurred between 9:50 and 9:55 p,m. along <br />the line. The final decision to stick with rainfall stimulation was <br />made when it was discovered that the extensive gust front which had <br />pushed out of the line, fan-shaped, to the northwest, west and <br />southwest were below all the planes, flying where updrafts <br />ordinarily would be strong. Often it'S the case that new clouds <br />form along and above gust fronts, however, this was not true <br />tonight. When seeding ended at 10:12 p.m. there was no indication <br />-of new storms building above the gust front, however, aircraft <br />patrolled atop the gust front as a precaution as it pushed deeper <br />into the target area. At 10:35 p.m. two aircraft began seeding to <br />stimulate rainfall in Greeley and Wallace counties. Seeding ended <br />there at 11:08 p.m.: all flight~ were terminated by 11:19 p.m. <br /> <br />The original line of storms, moving into Kansas from Colorado <br />before it collapsed and pushed out the gust front mentioned, <br />fizzled out over into the central parts of the Western Kansas <br />counties bordering Colorado. The line held together until after <br />midnight before eventually raining out just along the state line. <br />The continuous light rainfall looked excellent, too bad most of it <br />was wasted falling in Colorado since we probably did the most to <br />promote the persistence of the storms. <br /> <br />JUNE 13th - OPERATIONAL DAY #22: Initially a widely-spaced NNW-SSE <br />oriented line of building cumulus clouds began forming around 2:15 <br />p,m. All planes were scrambled between 2:30 p.m. and 2:44 p.m. <br />including the cloud top plane. AS time passed, two primary areas <br /> <br />,1-- <br />
