I live just outside Los Angeles. On July 22, 2006 (150 days ago) I was whining because it was 109.9 degrees outside.
This morning, it is 58 degrees inside my office with the heat on full blast. When I got in my car this morning, the back window was covered in frost and the temperature was 38 degrees. Supposedly it got down to 34 last night.
That's a temperature variance of 75.9 degrees. Seems pretty seasonal to me. I guess I've just grown weak and soft from years of California living.
