Some think it's a carbon copy.
What a spectacular afternoon. It feels like May or June, rather than the last couple of days of winter. Temperatures this afternoon will soar into the 70s across much of the region. Yesterday Boston broke a record high of 74°, breaking the old record which was set just last year of 70°. This afternoon we hit 74° breaking the record high of 72° set way back in 1903. Inland areas will once again reach for the mid 70s this afternoon with plenty of sunshine.
