Summer of 2013 Climate Review and Fall Preview

"Meteorological Summer" (June-August) of 2013 was "A Tale Of Two Cities" across south central and southeast Colorado. June was a very warm and dry month, which helped to spark several destructive wildfires across the area. The southwest monsoon came alive across Colorado in the beginning of July and remained very active across the state through the end of August, bringing beneficial rains to much of south central and southeast Colorado. The much needed rainfall brought some relief to the drought which has had it grip on the area over the past several years. However, the onset of the summer monsoon also caused destructive flash flooding across the area, especially for areas in and around the recent burn scars. The following graphics depict departures from normal values for both temperature and precipitation across the state for the Summer Season of 2013.  

 

   

 In Colorado Springs, the average temperature for the 2013 Summer Season was 70.7 degrees. This is 2.4 degrees above the seasonal average and makes the summer of 2013 tied with 1954 as the 8th warmest summer on record, well below the 73.3 degrees recorded just last summer (2012). Colorado Springs recorded 10.93 inches of precipitation through out the summer, with a combined 10.33 inches received through out July (4.61 inches) and August (5.72 inches). This is 2.25 inches above normal for the summer as a whole, and makes the Summer of 2013 the 15th wettest on record, well below the 16.85 inches received through the Summer of 1965. The combined 10.33 inches of precipitation recorded in July and August ranks as the second wettest July and August on record in Colorado Springs, just behind the 11.74 inches received in July and August of 1999. The 5.72 inches of precipitation received in August ranks as the 6th wettest August on record in Colorado Springs, well below the 7.09 inches recorded in August of 1929.

Pueblo recorded 5.87 inches of precipitation through out the sumnmer, which is 0.13 inches above the seasonal average.

Below is the Climate Prediction Center's temperature and precipitation outlook for the upcoming Fall of 2013 (September-November), which gives a  slight tilt of above normal temperatures (mainly across southwest Colorado) along with equal chances of above, below and near normal precipitation to all of south central and southeast Colorado for the period.
