1963: Unseasonably hot autumn weather peaked on October 5-6 with most stations across about the western two thirds of Iowa tying or breaking their all-time October warm temperature records on one or both of those days. On the 6th the highest reported temperatures were 96 F at Columbus Junction and 95 F at half a dozen stations including Fairfield, Grinnell, and Waterloo. At Des Moines the high was 94 F just one day after a high of 95 F on the 5th, and aside from these two days the warmest temperature on record at Des Moines in the month of October is 92 F. The warm weather continued for most of October and the first freezes of the season were generally not reported until the final week of the month. In many areas this remains the latest first freeze on record and the month finished as the warmest October on record in Iowa.

1935: Several unusually cold early October days culminated on the morning of the 6th when the temperature bottomed out at 12 F at Humboldt. Other reported low temperatures included 14 F at Belmond, 15 F at Decorah, Mason City, and Rock Rapids, 16 F at Fort Dodge, and 18 F at Atlantic.

6 October 1963 → For five days along the coast of Cuba, Hurricane Flora lashed the island with winds up to 100 mph and dumped over 70 inches of rain. The storm killed 7,000 people. 6 October 1972 → Arizona saw its first topical storm when the remnants of PacificHurricane Joanne made their way to the state. Up to 5 inches of rain fell. 6 October 1981 → A Fokker F28 passenger flight flew into a tornado near Moerdijk, Holland at an altitude of about 3,000 feet shortly after take-off. The plane experienced nearly 7 g of force, resulting in detachment of the starboard wing. On-board instruments recorded significant pressure variations as the plane entered, or neared, the vortex. The plane crashed, killing all 17 aboard. 6 October 2010 → Eight tornadoes tore through northern Arizona during the pre-dawn hours. It is the most tornadoes ever recorded in Arizona in a single day.
