Cumulonimbus clouds are those which form into thunderstorms.
The cloud seeding plane shot out a total of 26 flairs between both trips.
Since the clouds were at a warmer temperature than needed to shoot silver iodide flares, the pilot tried an alternative method, using a mixture of calcium and chloride.
The first time they went up they went southwest of Wichita Falls and the second trip was west around Lake Kemp.
City officials will have a better sense of how much cloud seeding helped the storm, if any, in a few weeks because they will get a report mapping out the flights and pinpointing exactly where the flares were shot.
