Investing.com - Natural gas futures extended heavy losses on Thursday, after data showed that U.S. natural gas supplies fell less than expected last week.
On the New York Mercantile Exchange, natural gas futures for delivery in April fell to a session low of $4.359 per million British thermal units, the weakest level since March 14.

The U.S. Energy Information Administration said in its weekly report that natural gas storage in the U.S. in the week ended March 14 fell by 48 billion cubic feet, compared to expectations for a decline of 59 billion cubic feet.
Supplies fell by 74 billion cubic feet in the same week a year earlier while the five-year average change for the week is a drop of 30 billion cubic feet.

Market analysts have warned that prices remain vulnerable to even further losses in the near-term amid concerns that the arrival of spring will bring warmer temperatures throughout the U.S. and cut into demand for heating.
Updated weather forecasting models showed that temperatures will be mostly normal in parts of the Midwest and Southeast through March 22 before turning colder.
The heating season from November through March is the peak demand period for U.S. gas consumption. Approximately 52% of U.S. households use natural gas for heating, according to the Energy Department.
