09:28 AM EDT, 10/10/2025 (MT Newswires) -- Natural gas prices weakened for a third-straight day on mild long-term forecasts and a larger than expected rise in inventories last week. Gas for November delivery was last seen down $0.10 to US$3.17 per million British thermal units.

The drop comes as long-term forecasts from the National Weather Service expect seasonal or cooler temperatures for the big markets of the Northeast following a long run of warmer than usual temperatures that offered some late-season cooling demand ahead of the Nov.1 start to the heating season.

In its weekly report on Thursday, the Energy Information Administration reported U.S. inventories of the fuel stored for winter use rose by 80-billion cubic feet last week, above expectations for a rise of around 76-bcf, according to NatGasWeather. The rise left stocks at 3.64-trillion cubic feet, 4.5% above the five-year average.
