雨fall Made Up About One Third of Warm Season Shortfall (Wetter to South)

The result was an offset of the lack of rain during the 2023 warm season. The rainfall deficit was the largest between May and mid-September (9.86 inches behind; 7.实际97英寸，17英寸.83 inches average; see above table), but St. 云拾起6.36 inches from September 22 through the end of October, making up about a third (3.09英寸)的巨大赤字.

Ross Carlyon, 国家气象局 Twin Cities climate guru, broke down the history of St. 云 warm season rainfall between the equinoxes. 他指出，在2023年， St. 云 had a shortfall well over 9 inches, making it the 5th driest warm season between the March and September Equinoxes. On the other hand, the period from September 23 through the end of October 是圣. 云记录, making up over 3 inches of the rain shortfall.

According to the comparison between the 10月3日1 US drought monitor and the September 19 US drought monitor (set to those dates on the 两周比较页面)，所有的区域在 extreme (bright red) and exceptional (brown) drought categories 缓解了. In the Twin Cities, where even more rain fell (10月12-14日超过2英寸; half inch to 2 inches Oct 23-28)， with over 5英寸(红色)代表这个月, all of the drought categories were dropped. In north central and central Minnesota, the 6-inch plus rainfall deficits since May still have the lower two categories of drought (棕褐色). Central Minnesota is running out of time to make up the shortfall before the ground freezes for the winter and the early November pattern hadn't produced much precipitation.

Warm October Makes 2nd Warmest May Through October

Temperature-wise, the heat through the first two-thirds of October had threatened 最温暖的10月前十名 since the average temperature was in the lower 50's. This was a statistical outlier, since only 8 days were more than 10 degrees warmer than average (October 5-17 was within 5 degrees either side of average). But, the late season cold, as well as the 快速下降的正常值 (high temperatures 10 degrees above average are in the 70's during the first week but are in the 60's in late October), 月平均气温降至 49.4度，3度.比平均水平高7度. That was merely the 31st warmest out of the 141 Octobers 在圣. 云记录.

仍然, it was yet another milder than average month, so the May through October average temperature is 65.0度，3.比平均水平高9度. That's the second warmest May-October temperature 在圣. 云记录. 只有1900年(66年).6度)更暖和. St. 云2023是0.3 degrees warmer than the 3rd place year of 1921. 基本上, all of 2023 has been warmer than average, 除了三月和四月, when the prolonged snow cover kept temperatures down.

这两个 90度——高位 at the start of the month ran the warm season total to 24 days, which tied 1935 as the 11th most number of 90 degree days on record. That was the most since the severe heat wave and drought year of 1988, which had 33 days with a high of 90 or above, 其中7个得分在100分或以上. 1988 is still the only year since the 1930's in the top 10 in 90 degree days and accounted for 7 of the 11 100 degree days since 1950.
