How do the local TV stations decide what counties to include on their Snow Watch/Snowbird maps? Channel 4 does not include, for example, Weakley County, on their Snowbird map, but yet they listed Weakley County among the counties that cancelled classes, on their crawls at the bottom of the screen. Meanwhile, channel 5 has another whole tier of counties in west Tennessee on their map that channel 4 does not have on theirs. Counties like Weakley, Carroll, Henderson, and Hardin are on the channel 5 map, but not on 4. None of the local channels have anything south of the Tennessee/Alabama state line, and nothing far enough east to be on the eastern time zone.
Neither channel has Calloway County, Kentucky, on their maps, but they still occasionally include the temperature in Murray, Kentucky, in their reports. At one time, channel 4's weather maps stretched as far west as Madison County, but obviously not anymore.
I didn't really include much about channel 2, because I have rarely, if ever, seen a map on their channel similar to what I've seen on 4 or 5, but I am also aware that their coverage area might be a bit less than that of 4 and 5, due to the existence of ABC affiliates in Bowling Green and Jackson.
