October snapped a 16 consecutive month streak of above normal temperatures across the contiguous United States. Still, climate meteorologist are confident, 2012 will become the warmest year on record, easily surpassing 1998. Records date back 117 years. The main reason for the record year, began with the warmest March on record. Forecasters believe much of the country will finish this year with near normal temperatures. Still the record for warmest year is expected to easily fall.
Interesting to note that while much of the country was warm last March, Portland was cool and wet, with a mean temperature more than three degrees below normal. In fact, so far PDX has had 6 out of 10 months this year be cooler than normal. The Northwest often goes opposite from much of the country in terms of weather. This a good reminder that impacts of a warming planet will continue to be very different from one region to the next.
