Forecasts for Frigid US Temps Push Nat-Gas Prices Sharply Higher

December Nymex natural gas prices surged over 5% to an 8-month nearest-futures high, primarily driven by updated forecasts predicting frigid US temperatures that are expected to significantly boost heating demand. This sharp rally occurred despite robust US natural gas production nearing record highs and overall adequate domestic inventories, suggesting the market is prioritizing short-term weather-driven demand increases. Active US drilling rigs also rose to a 2.25-year high, indicating continued supply expansion.

Analysis

December Nymex natural gas futures (NGZ25) surged +5.23% to an 8-month high, primarily driven by updated weather forecasts predicting frigid US temperatures. The Global Forecast System model shifted colder for the North Rockies and Northeast from November 14-18, and for the central US from November 21-25, signaling increased heating demand. This immediate weather-driven demand outlook overshadowed other market factors.

Despite the price rally, the supply side remains robust, with the EIA raising its 2025 US nat-gas production forecast by +0.5% to 107.14 bcf/day. Current US dry gas production is near record highs at 110.7 bcf/day (+11.7% y/y), and active drilling rigs increased by +3 to a 2.25-year high of 128, indicating continued supply expansion. US nat-gas inventories, while increasing by +33 bcf last week (matching consensus), remain +4.3% above their 5-year seasonal average, suggesting adequate overall supply.

Domestic demand for lower-48 states was strong at 92.6 bcf/day (+20.1% y/y), complemented by robust LNG net flows of 18.1 bcf/day (+4.1% w/w). US electricity output also showed modest year-over-year growth, contributing to underlying gas demand. European gas storage, at 83% full, is below its 5-year seasonal average of 92%, potentially supporting continued US LNG exports.

Key Decisions for Investors

• Investors should closely monitor evolving weather forecasts, as short-term frigid temperatures are the primary catalyst for current natural gas price strength.
• Maintain awareness of the robust US production and inventory levels, which could exert downward pressure on prices once weather-driven demand subsides.
• Evaluate potential hedging strategies or position adjustments to balance short-term weather-driven upside with longer-term supply-side bearish factors.
