We discovered last winter, that the TV stations do not post cancellations if they have just a few. They do, however, post all cancellations on their websites. So on snowy Sunday mornings, do click on the TV Channels' websites below (in blue) as well as watching your TV for cancellations. You can download an app for each station on your smart phone as well.
