On Sunday, September 15th, WPMI-TV switched to a new weather programming format for their digital sub-channel (virtual channel/radio frequency channel 15-2) that includes broadcasting national weather reports from the national TV programming service WeatherNation with customized weather graphics pertaining to parts of their local broadcast area (including current temperatures, predicted temperatures, heat indexes, and a weather radar map of the broadcast area) appearing near the bottom of the screen along with the current time for the areas and broadcasting local weather reports of their very own during breaks for the national weather reports.
The old format for the sub-channel used to have national weather reports from NBC Weather Plus, another national TV programming service dedicated to service, in addition to local weather reports on a regular basis ever since WPMI-TV began using the format in June 2005 upon their first broadcast on the sub-channel. The station stopped broadcasting weather reports from NBC Weather Plus in 2008 due to NBCUniversal's (the owners of the service) decision to end the service during that calendar year.
Another difference between the old format and the new format is the way their programs usually appeared on the sub-channel: the old format usually had local and national weather reports and advertisements appear in a small rectangle on the top-right corner of the display area of the channel while surrounded by weather graphics relevant to the station's local broadcast area such as current temperatures, predicted temperatures, the current time, and images such as clouds and suns indicating certain weather conditions. The new format has none of those graphics and its weather reports and some of its advertisements (produced in the 16:9 aspect ratio) can appear over the entire display areas of 16:9 TV sets or appear with black bars from top to bottom in the 4:3 display areas of the sets if their sources of the programming were standard-definition cable TV channels (the format or display settings for some TV sets receiving the sub-channel's new programming with an antenna may need to be adjusted in order for the programs to appear in their proper formats).
You may access a live video stream of WeatherNation's programming without local weather reports from WPMI-TV or the customized weather graphics pertaining to the station's local broadcast area that were normally on display during WeatherNation's reports by visiting the "On TV" section of the official World Wide Web site for WeatherNation.
