The rain hit as Halloween plans were shaping up around Lubbock High that fall, according to KFYO Lubbock News Talk. Nothing in the record suggests anyone saw it coming before it started, and once it did, it didn't let up.
The timing matters this year too. A slow-moving cold front dropped heavy rain and caused flash flooding across Texas at the end of September, weather that was expected to carry into October. Whenever that kind of system rolls through Lubbock, 1983 is the number it gets measured against.
For people here, that 5.4-inch mark works as a gut check on just how bad October rain can get. It's not an abstract record. It's the line forecasters and longtime neighbors point to when a fall storm starts dumping water on the South Plains and folks want to know how it stacks up.
More than four decades later, one October day in 1983 still outranks every fall storm Lubbock has seen since.
