US natural gas futures extended losses in after-hours trading on Wednesday as expectations for a larger-than-average increase in domestic gas inventories outweighed support from an intense heatwave expected to drive cooling demand across much of the country.
The front-month Henry Hub contract and the continuous contract fell 1.95% to $3.211 per million British thermal units.
Market participants await Thursday's weekly US Energy Information Administration storage report. According to Barchart, analysts expect natural gas inventories to rise by about 83 billion cubic feet for the week ended June 26, well above the five-year average injection of 64 Bcf for the corresponding week.
Gelber & Associates projected an 81 Bcf storage injection. "For now, the market is not ignoring the heat, but it is also not treating it as a reason for a clean breakout while storage remains healthy and the forecast moderates beyond the front-end heat pulse," Gelber & Associates said in a Wednesday market note. "Furthermore, most forecasting models have maintained warmer-than-normal summer temperatures for the past few months, so it is likely priced in at face value."
Near-term weather conditions, however, remain supportive of demand. Forecasts for July 1-5 continue to call for triple-digit daily highs across major population centers in the Midwest and Eastern US, lifting electricity demand and projected natural gas consumption.
However, prices also came under pressure as weather forecasts for mid-July turned slightly cooler, potentially easing demand for air conditioning among power generators. Barchart reported that the Commodity Weather Group expects near-normal seasonal temperatures across the eastern US during July 6-15.
Barchart, citing BNEF data, said Lower 48 US gas demand reached 80.2 Bcf per day on Wednesday, up 0.8 Bcf from the previous day and 4.0% higher than a year earlier. Celsius Energy estimated power-sector gas consumption at 39.2 Bcf on June 29, an increase of 3.9 Bcf from the previous day, although still 3.4 Bcf below the same day last year.
On the supply side, US dry gas production averaged 110.5 Bcf/d on Wednesday, down 1.6 Bcf from the previous day but still 1.7% above year-earlier levels, reflecting continued robust output.
Meanwhile, estimated net feedgas flows to US LNG export terminals slipped by 0.5 Bcf/d to 19.2 Bcf/d on Wednesday, remaining at historically strong levels and up 0.7% from a week earlier.
