Natural gas futures for first-half 2018 took a dive in the past week as the latest winter forecasts convinced market bulls to retreat.

In the short term, the Northeast braced for arctic air from an Alberta clipper from Canada racing from Michigan to New York. Fast-moving storms like this can be counted on for flight delays but not necessarily for a sustainable bump in natural gas prices.

Other news from Europe—the shutdown of the Forties Pipeline System in the North Sea and an explosion at Austria’s main gas pipeline hub—are unlikely to move the U.S. market much.
