In the wake of a record-setting wet September, October 1-22 was exceptionally dry across Minnesota. No rain fell from September 26 to October 22 at the Twin Cities International Airport, making it a 27-day stretch without measureable precipitation. This was the eighth longest stretch on record. The longest stretch of days without measurable precipitation in the Twin Cities is 51 days; from November 13, 1943 through January 4, 1944. The last time the Twin Cities has gone so long without measurable precipitation was a stretch of 30 days that ended on May 9, 1980.
October was quite warm. The average temperature through October 21 was six degrees above normal at the Twin Cities International Airport.
Naturally, one would expect that an October with so many dry days would be sunny. In fact, the first three weeks of October 2010 was the sunniest October 1-21 since solar radiation measurements began at the U of M St. Paul Campus Climate Observatory in 1963.
