Austin's main weather station at Camp Mabry recorded its largest 24-hour temperature swing ever: From 88 degrees at 3:15 p.m. Tuesday to 32 degrees as of 3:15 p.m. Wednesday — a stunning plummet of 56 degrees.

The previous 24-hour temperature-swing record was 51 degrees, and the National Weather Service said it had happened on three occasions:

• Feb. 8-9, 1994, from 4 p.m. to 4 p.m., when temperatures fell from 82 to 31 degrees.

• Dec. 21-22, 1990, from 9 a.m. to 9 a.m., when temperatures fell from 71 to 20 degrees.

• March 25-26, 1955, from 11 a.m. to 11 a.m., when temperatures fell from 86 to 35 degrees.

Interestingly, the record for the biggest 24-hour temperature upward swing back to warmth is much smaller. On Jan. 13-14, 1962, from 6 a.m. to 6 a.m., temperatures rose 40 degrees from 21 to 61 degrees.

The more surprising part was that it was 71 F on a December morning in Austin.

I'm surprised their third-rate power grid didn't fail again.

Impressive, especially how the temperature drop was recorded (or persisted) in the afternoon as well. Here, such drops only occur in the early morning the next day (after a warm 30C day), but then the temps would rise again by the afternoon (to at least 15C).
