September 2012 was the driest on record in Fargo Moorhead. Only 0.12 inches of rain was recorded that month at Hector Int’l which was 0.01 inches less than in September 1974 which was the previous driest September on record. Those extremely dry conditions that month were not only confined to our area.
Bismarck for example, recorded only 0.05 inches of rain in September. That, by the way, was not a record for them, as a meager 0.02 inches of rain fell on the state capital of North Dakota in September 1948. Although precipitation was more plentiful in October and November, the past three months ended up finishing well below average locally. In Bismarck, even with a slightly wetter November than average, the past three months ended up being the driest autumn on record for that city, with only 2.14 inches being recorded during the season.
The old record of 2.37 inches was recorded just last year meaning two straight extremely dry autumns for that area.
