<br />1990
<br />
<br />GENERAL I NTEJ'ESt: Al though rScords a:re st i 11 be i ng compiled, it
<br />appears likely the total number of crop-damaging hail claims across
<br />the state this yeiH' will be much higher than that recorded the past
<br />few years, Nor-wally, countiea in western and southwest"rn Kansas
<br />tend to follow the state trend in this statistic each year, Two
<br />items may !l/lve cau.sed :on above &ver!l,ge number of claims to be
<br />submitted: }o'irst, the gener.....lly excellent winter and spring
<br />moisture prtlduGed a whetlL crop that had the appearance, early in
<br />the season, of bel~e one of the best in Ye~rs, Overall, the crop
<br />Wo!lS potentially more valuable: hence, it would follow there would
<br />be a greater tendency to insure it, Second, it's common knowledge,
<br />as a state, Kansas has "",uffered much more severe W':ather in late
<br />spring a.nd ear-Iy fJUIlUller than it is usually accusn:.;lltled to. ,Severe
<br />weather by definition i6 accompanied by ds,maging hail, l1i811 winds,
<br />excessive rainfall, etc.
<br />
<br />Here in western and southwestern Kansas cr'op hail insurance
<br />rates have cenerally tr('!nded lower' and become more affordable over
<br />the years since the weat):;eor modification prog7"a11l began in 1975.,.11.
<br />striking comparison to the approximate 20% average increase in
<br />rates just II.c:ross the state line in Colorado since 1975.
<br />
<br />OPERATIONS: Generally, high pressure, high temperature and high
<br />moisture perSisted over' all of Kansas tbis past we e II: , Wi th
<br />temperatures soaring into the law 100's, regions of high moisture
<br />could be sufficiently warmed to a point where convective clouds
<br />could form and subsequently develop into severe thunderstorms,
<br />
<br />JUNE 25tb---OPERATIONAL DAY #16: Afternoon thunderstorm activity
<br />began forming near Goodland southwest to the Kansa:st'Colorado state
<br />11no west 0:1: Sharon Springs, All planes were scralnbled al'o\.md 4; 54
<br />p.lII., MDT, The strangest storll1$ remained ill Colorado being
<br />p.::ltrolled unti I s~eding began in eastern Cheyenne CrlUrlty, Colorado,
<br />When seeding beS<ln, an advancing NE-SW line of severe storms was
<br />nearing Wall<lce and Greeoley counties, All aJ.r':;r'aft seeded around
<br />this line of storms inside the lO-mile limit over that portion of
<br />both Cheyenne and Kiowa counties in Colorado, Three aircraft
<br />performed cloud base seeding from 6; 18 p. m. - 7: 15 p, m, \MDT)
<br />dispensing 304 grams at silver iodide; the cloud top plane
<br />dispensed 13,6 Kg dry ic~ between 5:30 p,m, and 6:44 p.m.
<br />
<br />As the NE-SW line moved eastel'ly, seeding continued over
<br />Wall<lce, Greeley and WJ,chita counties. The strongest new growth
<br />continued on the southern end of the line, eventually forming OVer
<br />Prowers County (Colorado) and Hamilton County. the line was
<br />patrolled as the stonns soon moved through l-\amilton County.
<br />Seeding was initiated by all three cloud base planes in eastern
<br />Hamilton County first begir.ning at 9: 19 p, roo Storms moved into
<br />Finney and Haskell counties where seeding continued and storm$;
<br />later weahened and dissipated. Seeding ended ~t 10:45 p,m.
