I found more Christmas flips in Northern New England. 100.9 WYNZ Portland flipped today at 12:00am according to yes.com with Snoopy's Christmas. 95.7 WZID Manchester also flipped today around 6am with Let it Snow! I also wonder if WERZ will flip to Christmas this year. Not that it matters to people in WERZ's coverage area because they have 4 stations that are already Christmas; WHOM, WZID, WODS and WROR.
I'm pretty sure that in past years, WZID has just flipped for the weekend following Thanksgiving, and maybe with Delilah at night, We may see that they're back to normal on Monday.
