According to my guide, as a part of Why I Love Winter Week, TWC will be airing a special program tonight titled, "Winter Remix," and apparently it's a compilation of the best of TWC's winter coverage; it's not quite clear if it's talking about just this year or if the show's going to take a look past into the past, but it should be interesting to check out.
It's going to air in place of WWCH at 9 PM ET, and it'll be a half-hour show followed by Epic Conditions at 9:30. Epic Conditions will air two half-hour shows on both Tuesday and Thursday night, and Friday night will again feature the Winter Remix/Epic Conditions combo. WWCH will reair only on Wednesday and Saturday night this week.
Also a little bit different is that, according to my guide, the previous night's long-form will re-air during the 2 PM ET block each afternoon; no word on whether Weather Center will air at 3 PM ET or if that block will still be FFN.
