-0.7 degrees from normal? That's close enough to call "normal" and not "colder" than normal in my opinion.
Based on what I am seeing in the monthly outlook, it looks like more cooler than normal weather for the balance of March and into April. The period you mention over the last 38 months with mostly above normal temperatures, could it not be related to high sunspot activity too? I agree about global warming, but how much is the sun influencing it. It is interesting to note that since the sun has been less active since late January, that the way above normal temps stopped in late January. In fact, we have not had a 70 degree day since January and in December we had 1 and January we had 3. The one on the 31st for me was a record for the date, occurring right after midnight. Is it possible that this will NOT be a hot summer like the last 3 years. Even in global warming, cooler temperatures can still affect certain parts of the world. Look how many months were below normal in 2009, and that is only 4 years ago.
