Most local TV stations air just a few weather reports a day: a forecast in the morning, perhaps an update in the afternoon, followed by an outlook for the next day at night. But when a winter storm was blanketing much of the U.S. earlier this month, Cleveland residents were able to get hourly updates on the situation on Haystack News—a TV news aggregator that recently began to use artificial intelligence (AI) to produce local weather reports.

Haystack built an automated workflow on top of Amazon’s AWS that uses LLMs, text-to-speech and an image generator to churn out new forecast videos every hour. It has been releasing these AI-generated weather updates for 30 cities, including Cleveland, Houston, Cupertino, Kansas City and St. Louis. The company has plans to expand the program to more than 100 locations over the next two weeks, and it aims to be in every U.S. city within a matter of months.

"We will try to get it done 100 percent this quarter," said Haystack News cofounder and CEO Daniel Barreto.
