Unusual Summer expected

It’s late June and I’ve released my forecast for the Summer of 2013.

With the devastating floods in Southern Alberta the forecast is likely not what we all want to hear. The reasons for the cold wet forecast down there is a combination of 3 things.

-A cycle created by excessive moisture. solar energy goes to evaporating the water instead of heating the ground, the water forms clouds and produces more rain putting down slightly less than what evaporated.
-Blocking has been predominant so far, currently a blocking pattern over Alaska has resulted in an extreme jet stream pattern and partly caused the great floods.
-The summers during such floods have had a history of being cold and wet. The summers of 2005 and 1995 were quite chilly. Summer 1986 also had a cooler soggy summer. A connection and not purely in indicator of what summer 2013 may bring.
