U.S. natural gas futures are on an upward trend for the seventh day in a row, driven by the cold weather sweeping across the U.S. and the subsequent surge in demand for heating. The frosty conditions are expected to persist into early March, further elevating demand for natural gas. Production freeze-offs have escalated due to the severe weather, while LNG exports continue to remain high, according to market analysts. Despite these conditions, technical indicators suggest an overbought market, and physical prices are likely to decrease early next week as daily demand drops.
