At one time I thought there were logos available for at least some of the regional weather networks, such as NortheasternWeather.net
I have an old one 'NEWN_logo_tea.jpg' but that is all I can find though I seem to remember it was part of a set that was provided by someone in a forum somewhere (likely on the previous forums at northeasternweather.net)
Would anyone know if there are others still available, even via individual/independent contributors?
