January 2014 Gulf Coast winter storm
The January 2014 Gulf Coast winter storm was a winter storm that impacted the eastern and southeastern United States, as well as Mexico, most notably the Gulf Coast region, which rarely receives frozen precipitation
==Meteorological synopsis==
As with most major winter storms in the American South, a low-pressure system formed near the western Gulf of Mexico, in this case, over Mexico on January 27,〔(【引用サイトリンク】title=WPC Surface Analysis Archive )〕 and eventually moved eastward. The breakdown of the normal polar vortex around the North Pole allowed an outbreak of frigid Arctic air to penetrate well into the South. The cold wave traveled much further south than normal, such that when the precipitation arrived from the Gulf Coast winter storm, freezing temperatures were occurring all of the way down to the coast.
Despite the unusually far southward incursion of cold air, the storm took a somewhat more northward track than initially expected, much to the relief of some areas that were spared, and much to the surprise of others further north that had not paid attention to later changes in weather forecasts and corresponding winter storm warnings.
On January 31, the weakened winter storm was absorbed into the circulation of another more powerful extratropical cyclone over the North Atlantic, while situated off the coast of South Carolina.〔(【引用サイトリンク】title=WPC Surface Analysis Archive )〕
