Worth knowing today

Denver should hit 86 today, enough to top the 84.9 record for the date set in 2020 (records since 1921) and run about 17 degrees above the normal high of 68.5.
record · heat
Columbus Day jumped 4 degrees overnight to around 80 in Denver, with the West Coast trough and the remnants of Hurricane Rachel staying well to the west. A backdoor cold front is the one thing that could still shave a few degrees off.
revision · holiday
Wednesday in Denver could land anywhere from 48 to 81, with a middle guess of 68. The swing depends on where the upper low tracks as it leaves the Southwest, and the latest runs lean toward a path north and east.
