The dominant cold period was 10月 16-27. All but one of the days during this period were at least 10 degrees colder than average (see 十月一日. 云 high-low temperature table).

The average temperature for 10月 18-27 was 26.8度(高31度.6、低21.9), typical of the weekend after Thanksgiving.

This cold surge ended up producing 7 record cold temperatures in the four days between 10月24日 and 28. The 27 degree high on the 25th was the 5th earliest high colder than 30 degrees in St. 云记录. The earliest one was 10月 17, 1930 when the high was 29. The temperature did end up getting down to 11 degrees early on the 27th, but the record cold low for that day was 5 degrees.
