target area; finally, a third series of storms began around 10:30 p~m. which affected the northwestern and central counties in the WKWM target area---lasting into the pre-dawn hours June 11th. The combined total flying time for these seeding operations was 55.4 hours. Around this time of year when so near wheat harvest, and the season's "big storm" does so much damage, there is a mistaken temptation to think the hail suppression program isn / t working very well. In actual fact the seeding aircraft are generally flying flat out during these storm days, expending their suppliss---often flying a second or third time. .For years we have been try!r,g to make the point that one of the greatest obstacles preventing us from doing a significantly better job is the lack or equipment and additional seeding supplies, plain and simple. Nothing will change unless funding support is increased. . OPERATIONS: Most of the week was hot and humid; thunderstorms Were about as hard to find this week as days without thunderstorms the previous week. All times indicated below are Central Daylight Time. .JUNE 17th - OPERATIONAL DAY 1120: Although there were no 1'adar echoes at the time at 5: 52 p. m., three cloud base planes and the Cloud top plane were scrambled to a visually developing isolated thunderstorm in southern Scott County, south of Scott City. By 6:24 p.m. radar was indicating large hail forming in the cloud. The cloud base aircraft had difficulty locating persistent updrafts~-- most likely because the extreme instability of the atmosphere this afternoqn may have forced air upward into the growing cloud from above cloud base. In any event some updrafts eventually found and seeding begun at 6:28 p.m. by two planes and joined shortly after- ward by a third. By the time the cloud top aircraft was on the thunderstorm it had moved northerly over Scott City and had begun dissipating, however, not before rain and some widely spaced large hail had dropped from it. The cloud top aircraft plane was sent to the storms developing in Grant County at 7:20 p.m. Previously, at 6:37 p.m. tbe fourth cloud base plane was scrambled to newly developing storms in Grant County and south of Grant County. Aircraft from the Scott City storm were begun to be diverted to this area as early as 7:06 p.m. All aircraft were eventually diverted to Grant County, but only limited seeding for hail was performed between 7;36 p.m. and 8:03 p.m.; patro1l1ng continued until 8:32 p.m. Total flight time for this operation amounted to 10.6 hours. ~.~.~;~ Curtis D.
