Digging thru the record books, I see 4, yes 4 only times I've had a +50 low in January. Jan 15, 1995 (54 degrees), Jan 5, 2004 (55.7 degrees), Jan 5,2005 (53.6 degrees), and Jan 12,2020 at 51.2 degrees. Today will make another as low at 7 am was 50.7 degrees (borrowing a miracle). My records go back to Oct 1979.
