US natural gas futures fell on Tuesday, snapping a record-breaking three-day rally. Traders completed exiting short positions, reducing upward pressure. The market now pivots to a historic winter storm forecast to blanket parts of the U.S., which typically boosts heating demand and prices.

The prior surge was fueled by aggressive short covering, where investors bought back contracts to limit losses after a sharp price drop. This volatility reflects the market's sensitivity to weather forecasts, which drive seasonal demand for natural gas used in heating and power generation.

Attention now shifts to the storm's actual impact on storage levels and pipeline flows. A prolonged cold snap could tighten supply and support prices, but any milder-than-expected outcome may trigger renewed selling. Traders will monitor weekly inventory data for confirmation.
