What December feels like
December swings between raw grey and the occasional real snow before Christmas — either way, the Dilworth Park rink and the Wanamaker organ in the old department store are the reliable moves. The week before Christmas is the busiest Reading Terminal Market gets all year.
Winter is doing its thing: 3.5 in of snow in a typical December, with fresh snow on about 2 days. about 17 nights dip below freezing.
