[9][10][11] On October 27, 2014, WeatherNation TV signed an affiliation agreement with the Sinclair Broadcast Group to carry its programming on a subchannel of the company's flagship station, WBFF in Baltimore.

[15] As a demonstration of the increasing political influence of far-right ideologies, in mid-January 2025, WeatherNation began airing repeated adds starring Eric Trump, far right podcasters, and patriot supplies including Trump-branded merchandise, indicating a pattern of increasing commercial and social influence of Trump.

[citation needed] As of January 2015[update], WeatherNation TV has current or pending affiliation agreements with 35 television stations in 33 media markets encompassing 21 states and the District of Columbia.

The national feed's carriage on certain cable and satellite providers is WeatherNation TV's sole method of distribution in markets where an over-the-air affiliate is not present.

WeatherNation TV affiliates, specifically those that operate a news department, have the option of breaking away from the network's programming to carry regularly scheduled programming from the station's primary feed – particularly, programs carried by the station's primary network affiliation – on the subchannel in order to accommodate breaking news or severe weather coverage, or telecasts of locally produced or syndicated sports events on the primary channel (depending on WeatherNation TV's subchannel placement and the station's carriage of additional subchannel services, especially those affiliated with a major network such as The CW or MyNetworkTV).

Although WeatherNation TV maintains a high-definition feed, its broadcast affiliates carry the network in 480i standard-definition in its default 16:9 widescreen format in order to preserve bandwidth to transmit the station's primary channel in high-definition; the HD feed is generally exclusive to certain pay television providers at their preference.
