 Brief Description: The storm approached the city from the west-southwest. There were unconfirmed reports of funnels in the Horseshoe Bay area, four miles southwest of Marble Falls, before the storm arrived. Spotty damage was reported to roofs in the Horseshoe Bay area. The tornado first struck the west side of the city, crossing a heavy commercialized and residential area. Roofs were severely damaged at this time with several structures sustaining F1 and F2 damage. Several boats at a dealership were tossed on top of each other. Two-by-four's were embedded into the side of a church preschool care center, penetrating an inside classroom wall by four to five feet. Fortunately, all children had been moved into hallways just before the tornado arrived. Numerous commerical signs were down with widespread roof damage. This damage became even more extensive as the tornado moved across the northern part of the city. Marble Falls primary school also sustained damage, but students had been evacuated to the main school. Trees were uprooted on the school grounds and damage was reported to outbuildings. Metal I-beams were bent at a nearby metal building, indicating F2 to F3 damage. Three nearby semi-tractor trailer delivery trucks and a bread delivery truck were overturned. Two of these trucks were reported to have been lifted "two to three feet off of the ground" as they were overturned. At a nearby Wal-Mart department store 100 to 200 employees had taken shelter, having practiced their severe weather drill the day before. The store was hit and severely damaged, with the employees sustaining only a few minor injuries. Additional roof damage was reported at Marble Falls High School. Students had just executed a tornado drill as the storm struck. There was extensive peeling of metal from the auditorium and gymnasium roofs. In summary, over 440 homes sustained damage, with one house and 17 mobile homes destroyed and major damage to 36 homes. Eighteen businesses reported major damage with 47 others reporting minor damage. In addition, two bridges were damaged, along with severe damage to schools. In all, 512 structures sustained damage.

 Brief Description: The same thunderstorm that spawned a brief touchdown in McCulloch County produced a second tornado south of Richland Springs. A hunting cabin, two trailer homes, 2 barns, and 3 vehicles were destroyed. Several rounds of thunderstorms developed across West Central Texas on the morning and afternoon of the 12th. The first round of storms brought dime to golf ball size hail to parts of the Northern Edwards Plateau, Concho Valley, and the Heartland. A second round of storms that developed during the early afternoon produced a supercell across the southern Heartland. This storm dropped a tornado south of Brady in Southern McCulloch County, as well as hail up the size of golf balls in the town of Brady itself. As the supercell moved into San Saba County, a second tornado would touch down. This tornado had an 8 mile long path and was 100 yards wide, passing 8 miles south of Richland Springs. Although each tornado would produce damage, no injuries or deaths were reported.

 Brief Description: The fourth tornado that was produced by the large supercell thunderstorm developed on the north side of Lake Belton, near Morgans Point where a marina was destroyed. Over 100 boats at the marina were destroyed by the strong tornado that moved slowly south-southwest. Ten homes along the lakeshore also sustained severe damage and damage to trees was nearly total. The tornado dissipated just northeast of Woodland.

 Brief Description: Several eyewitnesses reported that the Jarrell tornado was preceded for a period of 8 to 10 minutes by a series of short-lived very small tornadoes that formed from the same supercell thunderstorm. These touched down, then dissipated in order. The first tornado in Williamson County formed near 2:25 pm CST and built rapidly to F2 strength. It survived for approximately 8 minutes, often returning briefly to a roped and tilted feature before it died. This tornado was followed by a second that formed near 2:35 pm CST. It built quickly into a multi-vortex tornado that appeared to be near F2 strength as well. This dissipated after only 4 minutes. The final tornado from this same supercell, , the Jarrell Tornado, developed as a small...rope-shaped tornado, touching down around 2:40 pm CST inside the Williamson County line northwest of Jarrell. From film and eyewitness accounts, it expanded quickly into a very large vortex nearly 1/2 mile in width. Observations recounted by eyewitnesses indicated that the damage path may not have been made strictly by one tornado. A number of eyewitnesses reported seeing several small, rope-like funnels before the character of the tornado changed drastically into the killer tornado. Ground damage patterns in the Double Creek Subdivision also suggested this possibility. The tornado crossed CR 308, CR 305, and then CR 307. Where the tornado crossed each of these county roads, approximately 525 feet of asphalt was ripped off each of the roadways. This particular destruction was believed to be very close to the centerline of the tornado circulation. As the tornado crossed the intersection of CR 305 and 307, a business on the corner was destroyed. The tornado moved into the Double Creek area at this point with total destruction. F5 destruction continued from shortly after its formation until very close to the end of the damage path. The tornado began a brief turn toward the southeast as it entered the Double Creek subdivision and the surrounding area, moving very slowly. It reached the subdivision at 3:48 pm. This time is based on a clock found at a destroyed residence in the extreme northwest corner of the subdivision and the home believed to be the first struck by the tornado. Here, it widened to it maximum width of three-quarters of a mile. From the air, the ground appearance changed abruptly in the vicinity of CR 308 and continued until very near the end of the path. No definitive circulation patterns or suction spots were evident, but there was the noted obvious change in the appearance of the ground. In the Double Creek area, approximately 40 structures were totally destroyed. One of the most striking signs in approaching this area was the distinct lack of debris of any size. Closer inspection showed lots of little debris but no sign of large items. It was estimated that several dozen vehicles had been in the subdivision and removed by the tornado. Nearly 300 cattle grazing in a pasture near the subdivision were also killed, with many of them tossed and blown for over 1/4 mile. At least half a dozen cars were identified from the air lying in the open areas, most of them flattened and encrusted with mud and grass. Trees in the subdivision were completely stripped of bark. Later ground survey revealed that most of the debris that was left in the area was extremely small indicating the power of the tornadic wind. All 27 deaths associated with the Jarrell tornado occurred in the Double Creek area. Eyewitnesses reported that it appeared to have slowed down as it entered the subdivision, and that may account for the nearly total destruction that took place. After passing through the Double Creek area, the tornado shifted its track again slightly, moving toward the south-southwest across CR 309 and into a heavily wooded area of cedar trees. The total destruction of the tornado ends abruptly shortly after entering the wooded area. However, a small swath of tree damage on the north side of the main damage path suggested the possibility of a multiple vortex pattern. No other evidence of multiple vortices was observed. The sequence of weather phenomenon reported with this tornado was exactly opposite of that often reported- the tornado first appeared, followed by nearly calm conditions, then hail, followed by rain and finally brief, gusty winds. This is attributed to the fact that the parent supercell was moving toward the southwest for most of its life. The storm essentially "backed into" the area as it moved.

 Brief Description: A strong weather system produced scattered showers and thunderstorms over Central Texas on the afternoon of Thursday March 16. Funnel clouds were first reported by the public and by the Leander Police Department near 4 pm that afternoon. A small, short-lived F0 tornado struck near the police station near 4 pm, with no significant damage. Shortly after 4 pm, another rope-shaped funnel was observed west of Leander. Photographs of this developing tornado indicate a generally-long and rope-shaped structure that slowly twisted and wound its way to the surface. The tornado touched down in the western part of Mason Creek Subdivision located on the west side of Leander and moved slowly eastward. Damage near the tornado touchdown was F0 level approaching F1. It damaged eaves of roofs, took shingles off roofs and knocked down large tree branches. More significant damage was noted along Greening Way and Mason Creek Boulevard in the west and central part of the subdivision, where several large trees of over 1 foot diameter were uprooted. This indicated damage in the lower levels of the F2 scale. In addition, the tornado had destroyed approximately 30 percent of one home. Again, this indicated minimal F2-level damage. The tornado began to lift as it approached Old Bagdad Road on the eastern side of the subdivision. Most of the damage in this part of the subdivision was at the F0 level. In all, the tornado damaged 24 homes and several outbuildings. The tornado was estimated at 200 yards wide with a path length of 1.5 mile.
