Widnall was born and raised in Tacoma, Washington, graduating from the Aquinas Academy for Girls in 1956. She graduated from MIT with a SB in 1960, SM in 1961, and ScD in 1964, all in Aeronautics. Her master's thesis was entitled Boundary layer stability over flexible surfaces and her doctoral thesis was entitled Unsteady loads on hydrofoils including free surface effects and cavitation, both under the supervision of Marten T. Landahl.
Widnall was appointed as the Abby Rockefeller Mauzé Professor of Aeronautics and Astronautics in 1986 and joined the Engineering Systems Division, was Chair of the Faculty 1979–1981, and has served as MIT's Associate Provost from 1992–1993. In 1988 she was the President of the American Association for the Advancement of Science. She was elected to the American Academy of Arts and Sciences that same year.

Her husband earned a doctorate degree from MIT in aerospace engineering and headed the MIT-Draper team that developed the Apollo GN&C system. The couple has two grown children, William and Ann Marie.
Widnall's research has been focused on fluid mechanics, in particular the aerodynamics of high-speed vehicles, helicopters, aircraft wakes, and turbulence. One of her most notable works is on the elliptical instability mechanism with Raymond Pierrehumbert.
