In my area, it comes on every Sundays at 5:00 AM CDT on WMBD-TV (CBS affiliate).
I was hoping my favorite TV station, WEEK-TV (NBC affiliate) would get it (hence NBC Weather Plus). But no, instead, it ended up on one of my market's worst stations (that also has a low-rated, libral-biased newscast). No offence of course. It just that I hate CBS!
At least WMBD-TV isn't a CBS O&O station. It just that I perfer NBC, and CW affiliates as well as inpendent stations.
I also wish they would move all of my other favorite syndicated shows to my favorite TV station too. My brodcasting market sucks around here including my radio market.
