His father was a photographer and model-airplane distributor who was an Army projectionist in WWII. Tim assisted in the photography and shop work. Samaras first became interested in tornadoes at age six, when he watched ''
The Wizard of Oz'' on television with his mother. "When the tornado appeared," he recalled, "I was hooked!"
Samaras attended Lasley Elementary and O'Connell Junior High in Lakewood, before graduating from
Alameda International Junior/Senior High School in 1976.
In his twenties, he began to chase storms "not for the thrill, but the science."

Samaras was the founder of a field research team called Tactical Weather Instrumented Sampling in Tornadoes EXperiment (
TWISTEX), which sought to better understand tornadoes. His work was funded in large part by the

The probe was dropped in front of the oncoming tornado a mere 82 seconds before it hit.
The measurement is also the lowest pressure (adjusted for elevation) ever recorded at Earth's surface, . Samaras later described the tornado as the most memorable of his career.

In total, he tracked down more than 125 tornadoes during his career.
His colleagues considered him to be one of the most careful chasers in the business.
Beginning in 1998, Samaras founded and co-produced (with Roger Hill) the National Storm Chasers Convention, an annual event held near

Samaras' widow, Kathy, revealed in her first news interview after his death that she would continue ChaserCon, which consistently attracts luminary scientists and chasers as speakers. In 2005, he was named an "Emerging Explorer" by the National Geographic Society.

. The TWISTEX vehicle was struck and thrown by a subvortex, which generate the highest winds; some of these were moving at within the parent tornado.
Shortly before they were killed, Young noted how there was no rain around the vehicle as the wind grew "eerily calm". Tim Samaras responded: "Actually, I think we're in a bad spot." According to
Oklahoma Highway Patrol Trooper Betsy Randolph, the three could be heard screaming "We’re going to die, we’re going to die" over her patrol radio moments before the impact.

all of which combined so that several other chasers were also hit or had near misses. It was the first known instance of a storm chaser or a meteorologist killed by a tornado.
Even before it was known that Samaras, his son, and Young had been killed, the event led many to question storm-chasing tactics, particularly in close proximity to tornadoes. In addition to the three TWISTEX members, the tornado killed five other people, including local resident Richard Charles Henderson, who had decided to follow the storm.
Atmospheric scientists and storm chasers embarked on a major project to gather information and analyze what happened regarding chaser actions and meteorological occurrences. A makeshift memorial was established at the site soon after the incident
and a
crowdfunded permanent memorial, spearheaded by Doug Gerten, the deputy who first found the vehicle wreckage, was later established, although it was vandalized in late March 2016, with the monument struck by bullets and the American flag cut away from the flagpole.

Meteorologist
Jim Cantore remarked, "This is a very sad day for the meteorological community and the families of our friends lost. Tim Samaras was a pioneer and great man."
''National Geographic'' remarked, "Tim was a courageous and brilliant scientist who fearlessly pursued tornadoes and lightning in the field in an effort to better understand these phenomena."
