US natural gas prices rose as weather forecasts turned hotter and LNG feedgas flows to export terminals increased, EnergyNow reported, citing the twin demand-side drivers that have anchored the bull case for US gas through the summer cooling season.

The move puts the market's focus back on two measurable variables: cooling-degree-day expectations across the Lower 48 and the volume of gas moving to Gulf Coast liquefaction plants. Both tightened on the day, and traders responded by bidding up prompt supply.

Why did the weather shift matter?

Forecasters revised temperature outlooks toward hotter conditions for key consuming regions. Hotter weather raises air-conditioning load, which pulls on gas-fired power generation — the largest single source of US gas demand during summer months.

Weather-driven demand revisions are the most common short-term price catalyst in the US gas market. A single hot forecast cycle can swing expected power-burn by billions of cubic feet per day, and Friday's shift followed that pattern: expectations moved first, then prices.

How much did LNG flows support the move?

Feedgas deliveries to US LNG export terminals also rose, according to the report. Higher flows to the terminals signal stronger liquefaction and export demand, absorbing supply that would otherwise pressure domestic storage.

US export capacity has grown as new liquefaction trains along the Gulf Coast ramp toward full rates, making feedgas demand a structural floor under the market. When terminal offtake rises at the same time weather demand improves, the two drivers compound — the configuration that lifted prices in this session.

What should readers watch now?

The watch items are straightforward.

• Storage: the next weekly EIA injection report will show whether demand strength is already trimming the build rate against the five-year average.
• Weather models: forecast revisions remain the dominant short-term driver; a cooler turn would unwind the weather premium quickly.
• LNG feedgas: sustained higher nominations would confirm the export-demand leg of the move rather than a one-day fluctuation.

EnergyNow's report attributes the gain to the weather shift and the LNG flow increase — a demand-side story, with no supply-side disruption cited.

For now, the market is trading heat and exports, not production. That balance holds until either the forecast turns or a supply event intervenes.
