Meanwhile, natural gas traders continued to focus on tropical storm activity in the Gulf of Mexico, amid concerns over a disruption to supplies from the region.
The U.S. National Hurricane Center upgraded a storm system in the southwestern Gulf of Mexico into Tropical Storm Ingrid on Friday.
However, the agency said the storm was on course for landfall on Mexico's east coast, instead of threatening gas production facilities in the U.S. Gulf region.
Energy traders track tropical storm activity in the event it disrupts production in the Gulf of Mexico, which is home to nearly 5% of U.S. natural gas production.
Market players also monitored near-term weather forecasts to gauge the strength of demand for the fuel.
Updated weather forecasting models pointed to mostly normal to below-normal temperatures across most parts of the U.S. Northeast Midwest for the next ten days.
