US natural gas futures climbed in midday trading on Wednesday, supported by hotter near-term weather forecasts and expectations that weekly storage injections will remain below year-earlier levels for an eighth consecutive week.
The front-month Henry Hub contract and the continuous benchmark both rose 1.82% to $3.193 per million British thermal units.
According to NRG, a brief heat event is expected across much of the Midwest and Northeast through the end of the week, with temperatures reaching the 90s Fahrenheit. However, the firm noted that temperatures are forecast to return to average or below-average levels across much of the country after this week.
Looking further ahead, Trading Economics said additional support came from forecasts calling for above-normal temperatures during the second half of June.
NRG said that both June 2026 month-to-date demand and overall 2026 year-to-date demand are running about 1 billion cubic feet per day below the levels seen during the same periods last year. However, the company noted that structural growth in the power burn sector, particularly from data centers, is averaging roughly 0.5 Bcf/d higher on both a June month-to-date and 2026 year-to-date basis compared with the corresponding periods in 2025.
Meanwhile, Trading Economics, citing LSEG data, said average natural gas production in the US Lower 48 states has eased to 108.8 Bcf/d so far in June from 109.7 Bcf/d in May and that reduced production was showing up in weaker inventory injections.
The last seven storage reports have each recorded injections below year-ago levels, gradually eroding the five-year average surplus to the current 5%. NRG said market participants are forecasting a 101 Bcf injection for the week ended June 5, 8 Bcf lower than the build a year ago.
On the export side, Trading Economics said net flows to major US LNG export terminals have fallen to 16.3 Bcf/d so far in June from 17.1 Bcf/d in May. Seasonal maintenance at facilities, including Golden Pass and Freeport LNG in Texas, has continued to weigh on export volumes, the firm said.
