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). Most of those days generated a high around the freezing mark with lows as cold as the 20s and even a few teens (see NWS圣. 云 10月 high-low temperature graph). 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.

The cold weather was produced when the upper air high pressure area that spent most of the summer along the West Coast of North America pulled westward into the eastern Pacific. The northwest-to-southeast steering wind pattern allowed much colder than average air to push consistently from the Northern Plains through the Great Lakes and into the Mid-Atlantic.
In keeping with the yo-yo trend of the fall, there were still 5 days with a temperature at least 8 degrees warmer than average. This included an 81 degree high on 10月9日th. That's among the latest 15 percent for the last 80 degree in 10月. We may be done with 80 degree days in St. 云 in 2020, but there is a good chance for a 70-degree high during the first week of November.
One factor that helped with the cold was early season snowfall. 10月20日, a snowstorm produced a widespread 6-9 inches over central and southern Minnesota. 10月22日, St. 云 barely missed yet another shovelable snowstorm, producing 6-10 inches from Breckenridge and Fergus Falls to Little Falls, Royalton, 和Pierz. 不过,圣. 云最终得到7分.0 inches of snow from the 10月20日 storm, breaking the daily snowfall record. That snow helped to keep temperatures cold since some of the sun's heat is lost melting the snow.
St. 云最终得到了7分.8 inches of snow for the month of 10月, breaking the previous 10月 record (set in 1936) by a full inch. 记录s were also set in the Twin Cities 在德卢斯有前科.

There were also 6 10月 days with a high of freezing or colder, the most in St. 云记录 dating back to 1893. The old record was 5 days in 1925. There were 21 days with a low of freezing or colder, which was the third most in the month of 10月. The record was set in 1988 (25 days).
The growing season came to an end with a hard freeze and a low of 27 degrees on 10月 2. 这大约晚了一个星期 for the median date of the first frost, but nearly right on time for the first 28 degree temperature. 最后一次霜冻日期 in the spring was May 12, so the growing season between frost days in St. 云 was a total of 143 days, in the upper half of longest growing seasons (average 137 days). 然而, it was a bit short on days without a freeze (also 143 days, since the first and last frost date had lows of 27 degrees). St. 云 averages 158 days between freezes.
