Through Friday, we've had a pretty similar April compared to last year in terms of days where we've been above 70 or 80 degrees. It was a bit unusual for us this year because it took until April for us to get our first 70 degree day (unless you're in Delaware, where it happened in January), where most years we're hitting 70 for the first time in March.
That said, the level of warmth this year, mostly in the past two weeks, is pretty consistent with what April 2012 pulled off. Last year, Philadelphia had seven days of 70 or warmer through the 19th. This year, we also had seven. Most of the numbers across the board were pretty consistent as well for locations around the region.
