The IRI outlook for seasonal average temperature for June-August 2015 issued in the third week of May. Red areas indicate places with an increased chance for above normal temperature, while blue areas show an increased chance for below normal temperature. “Normal” is defined by the temperatue that was observed in middle one-third of the cases during the 30-year period of 1981-2010. The color shading shows the probability for above-normal (if red) or below normal (if blue) temperature. White areas indicate no forecast direction, which implies an equal (33.3%) probability for any of the three possibilities (below normal, near normal or above normal).
