Look at these lovely green leaves from May 18, 2010.
Now look at the same exact tree (at a wider angle) 363 days later. Leaves are barely unfolding. Out west they had a frost warning last night. So yes, you are colder than usual this spring. Or at least colder than last spring. I can't go back to 2009 for this view because I was still taking pictures from my office window (this was in the pre-reflective film days) so I don't have any of this tree. The one outside my window, then as now, is in full bright green leafiness. Someday I might add a time/temp feature just to help track these things.
