On May 19, the mercury reached 97 degrees at the Twin Cities International Airport. This was the warmest temperature recorded in the Twin Cities for so early in the season. The previous first date of a temperature of 97 degrees or above was May 22, 1925. In fact, there are only three years in which the temperature has been 97 or above in May. Those years are: 1925, 1934 and 2006. The warmest temperature ever recorded at the Twin Cities official observing site in May is 106 degrees on May 31, 1934. Looking at 1890 to 2008 only about half the years reach 97 degrees as the warmest temperature for the year.

Another interesting aspect about the temperatures on May 19 was the extreme range found in the state at the same time. At 4pm it was 34 degrees in Grand Marais with a chilly breeze off Lake Superior and 100 degrees at Granite Falls, a difference of 66 degrees. A temperature range of 40 degrees at the same time in Minnesota happens on occasion, but a range of 60 degrees or more would be quite rare, and a range of 66 degrees may be unique. There was even some freezing rain reported along the north shore. One person who lives near Devil Track Lake in Cook County had ice coating his mailbox on the evening of the 19th.

Below is the hourly round-up for Minnesota from 4pm May 19, 2009 from the National Weather Service.
