June 1 marked the first day of meteorological summer. The just completed spring season was a testament on how our climate varies from year to year. You may recall that the spring of 2012 was the warmest on record with an average temperature of 50.2 degrees which was nearly 1 degree warmer than the previous warmest spring on record set in 1977.
Preliminary numbers for the spring of 2013 season suggest an average temperature of 36.3 degrees which would rank our just completed spring as the 10th coldest on record. That was just barely warmer than the spring of 1996, the most recent year with similar spring weather. That year the average spring temperature was 36.2 degrees.
Because the recent heavy rain event hit the north metro and the official sensor at the airport especially hard, the period from March 1 to May 31 will end up ranking as the 2nd wettest spring since records started in 1881.
