US natural gas futures fell more than 1% on Friday to around $2.85/MMBtu, reversing the previous session’s gains as cooler weather forecasts reduced expectations for late-September cooling demand. The latest forecasts show above-average temperatures covering a smaller portion of the South and Southeast from September 22 through October 1, potentially reducing natural gas demand from power generators for air conditioning. The bearish weather outlook comes despite a tighter-than-expected weekly storage build and continued concerns about the US inventory surplus.
The market remains caught between strong production and softer weather-driven demand on the bearish side, while tighter storage fundamentals and LNG export demand provide important bullish counterweights. Lower 48 production averaged 113.1 bcfd in September, above August’s record monthly average of 112.2 bcfd, while average flows to the nine major US LNG export facilities were expected to fall to a three-week low of 17.5 bcfd, largely because of maintenance at Cameron LNG in Louisiana.
Why Are US Natural Gas Prices Falling Today?
The immediate catalyst behind Friday’s decline is a shift in the weather outlook.
Natural gas demand typically rises during periods of extreme summer heat because gas-fired power plants supply electricity for air conditioning. The latest forecasts, however, indicate that above-normal temperatures will cover a smaller area of the South and Southeast between September 22 and October 1.
That potentially reduces electricity-sector gas consumption at a time when the market is already dealing with exceptionally strong production.
The combination creates a familiar pressure point for natural gas:
More production + less weather-driven demand = greater potential for injections into storage and weaker prices.
However, the market is not facing an entirely bearish fundamental picture.
Thursday’s rally demonstrated that traders remain sensitive to storage data, with the latest EIA report showing a smaller-than-average inventory build.

US Natural Gas Storage Surplus Is Narrowing
One of the most important bullish signals underneath the market is the recent improvement in the US storage balance.
The EIA reported a below-average storage build for the week ended September 11, causing the inventory surplus relative to the five-year average to narrow to 118 Bcf from 148 Bcf one week earlier.
That represents a meaningful reduction in the surplus.
The smaller storage build indicates that gas consumption was stronger than expected, with late-season heat increasing demand from the power sector.
This is why Thursday’s natural gas rally was significant.
Even though US production remains extremely high, demand was strong enough to produce a tighter-than-normal weekly storage injection.
The problem for bulls is that the weather forecast has now become less supportive.
If cooler conditions reduce power-sector demand while production remains around record levels, future storage injections could begin to look less constructive.
Record US Natural Gas Production Remains a Major Bearish Factor
Production is arguably the biggest structural bearish factor facing the natural gas market.
Lower 48 production averaged 113.1 bcfd during September, exceeding August’s record monthly average of 112.2 bcfd.
That means the market is entering the end of the summer cooling season with exceptionally high supply.
The significance is straightforward.
If production continues to exceed demand growth, more gas can flow into underground storage. That could prevent the recent narrowing of the storage surplus from continuing.
For natural gas bulls, the key question is therefore whether demand can absorb this additional production.
So far, LNG exports and power-sector consumption have provided important outlets for US gas. But both are currently facing potential near-term limitations.
Cooler Weather Could Reduce Power-Sector Natural Gas Demand
Weather remains one of the most important short-term drivers of US natural gas prices.
The latest forecasts indicate that above-average temperatures will cover a smaller area of the South and Southeast from September 22 through October 1.
That matters because these regions can generate substantial natural gas demand from electricity producers during periods of intense air-conditioning use.
As temperatures moderate, electricity demand for cooling can decline.
Gas-fired power generation may therefore require less fuel.
This creates a potentially bearish combination with record production.
If the weather turns cooler faster than expected, the market could lose one of its most important late-season demand supports just as supply remains elevated.
LNG Export Demand Faces a Temporary Headwind
US LNG exports have become one of the most important sources of structural natural gas demand.
However, average flows to the nine major US LNG export facilities were expected to fall to 17.5 bcfd, their lowest level in approximately three weeks.
The decline was primarily attributed to maintenance at Cameron LNG in Louisiana.
Lower LNG feedgas demand means more natural gas remains available within the domestic US market.
That can place additional pressure on prices, particularly when domestic production is already running at record levels.
The maintenance issue is important, however, because it does not necessarily represent a permanent deterioration in LNG demand.
Once maintenance is completed, feedgas flows could recover.
Storage, Production and LNG Demand Are Pulling the Market in Different Directions
The current natural gas market is being driven by several competing forces.
On one side, the storage data has improved.
The surplus against the five-year average has narrowed from 148 Bcf to 118 Bcf, suggesting the market has become tighter relative to historical norms.
On the other side, production has reached new highs.
At 113.1 bcfd, September output is running above the previous record monthly average.
Meanwhile, LNG feedgas demand is temporarily weaker because of maintenance, while cooler weather threatens to reduce power-sector consumption.
The result is a market where the fundamental picture cannot be reduced to a single indicator.
Storage is improving, but supply remains abundant.
Demand has been strong enough to tighten the surplus, but weather forecasts are becoming less supportive.
LNG exports remain structurally important, but current flows are temporarily weaker.
Bullish Sentiment
1. Storage Surplus Is Narrowing
The storage surplus has declined to 118 Bcf from 148 Bcf, demonstrating that recent demand has been strong enough to tighten the market relative to the five-year average.
2. Below-Average Storage Build
The EIA’s latest below-average injection provided evidence that late-season demand remains capable of absorbing significant volumes of natural gas.
3. Power-Sector Demand Could Remain Resilient
Although the latest forecasts are cooler, temperatures across parts of the South and Southeast remain important. Any renewed heat could quickly increase air-conditioning demand and gas-fired power generation.
4. LNG Exports Remain a Structural Demand Driver
US LNG exports continue to represent a major source of natural gas demand. The current reduction in feedgas flows is linked largely to maintenance, meaning demand could recover when facilities return to normal operations.
5. Weather Forecasts Can Change Quickly
Natural gas remains highly sensitive to changes in weather models. A renewed period of hotter temperatures could quickly reverse some of the current bearish pressure.
Bearish Sentiment
1. US Production Is at Record Levels
September Lower 48 production is averaging 113.1 bcfd, above August’s record 112.2 bcfd.
This provides the market with substantial supply and increases the risk of larger future storage injections.
2. Cooler Weather Reduces Cooling Demand
The latest forecasts show a smaller area of above-average temperatures between September 22 and October 1, potentially reducing gas demand from power generators.
3. LNG Feedgas Flows Are Falling
Flows to major US LNG export facilities are expected to decline to 17.5 bcfd, a three-week low.
Until maintenance-related disruptions ease, that leaves more gas available for the domestic market.
4. The Storage Surplus Still Exists
Although the surplus has narrowed, inventories remain 118 Bcf above the five-year average.
That means the market has not eliminated the excess supply accumulated relative to historical norms.
5. Strong Production Could Overwhelm Demand
The most important bearish risk is that production continues rising while both weather-related demand and LNG feedgas demand soften.
That combination could cause the storage surplus to widen again.
The Key Battle: Record Supply Versus Tightening Storage
The central question for natural gas traders is whether the recent improvement in storage fundamentals can continue.
A 30 Bcf reduction in the storage surplus is constructive.
But it occurred during a period when late-season heat supported power demand.
If cooler weather reduces consumption while production remains above 113 bcfd, the market could quickly lose some of that improvement.
This makes upcoming EIA storage reports particularly important.
Traders will be watching whether injections remain below historical averages or begin to accelerate as temperatures moderate.
What Traders Are Watching Next
Natural gas traders will be monitoring several key variables:
- US weather forecasts for late September and early October.
- EIA weekly storage injections and changes in the 118 Bcf surplus.
- Lower 48 production, particularly whether output remains above 113 bcfd.
- LNG feedgas flows as Cameron LNG maintenance progresses.
- Power-sector gas demand as cooling requirements decline.
- Hurricane and extreme-weather developments that could disrupt production or demand.
- Forward natural gas prices as traders assess winter storage requirements.
The biggest potential market catalyst remains the interaction between weather and production.
Currency Hedger View
For international energy companies, LNG businesses, commodity traders and industrial consumers, the natural gas price is only one component of total financial exposure.
Natural gas is primarily priced in US dollars, meaning companies operating with revenues or costs in euros, pounds, UAE dirhams or other currencies can face an additional FX risk when natural gas prices move.
A fall in US natural gas prices may therefore have a different financial impact depending on the company’s underlying currency exposure.
Currency Hedger, the FX and hedging division of Octalas Group, focuses on helping businesses manage currency exposure associated with international payments, receipts and commercial transactions.
For companies exposed to energy markets, separating the commodity-price risk from the currency risk can provide a clearer view of overall financial exposure.
Today Markets View
US natural gas futures are under pressure as cooler weather forecasts threaten to reduce power-sector demand just as production remains at record levels.
The move to around $2.85/MMBtu reflects the market’s concern that supply could once again outpace demand as the summer cooling season fades.
However, the bearish picture is not complete.
The EIA’s latest report showed a below-average storage build, while the surplus against the five-year average narrowed significantly from 148 Bcf to 118 Bcf. LNG exports also remain a major structural source of US gas demand, even though Cameron LNG maintenance is temporarily reducing feedgas flows.
The market therefore faces a clear fundamental conflict.
Record production, cooler weather and weaker LNG flows are bearish, while tightening storage balances, resilient power demand and the potential recovery in LNG exports provide bullish counterweights.
For traders, the next major signal will come from whether storage injections remain below historical norms as temperatures moderate. If production stays above 113 bcfd while demand weakens, the pressure on natural gas prices could intensify. Conversely, renewed heat, stronger LNG flows or another series of below-average storage builds could provide support.
