During the Northern Hemispheric winter of 2013–14, North America became the breeding ground for several storms, many of which had significant impacts. In several states in the US, there were record temperatures, some of which were the result of southward movements of the polar vortex.

Storm events

October 4–5

The first winter storm of the season, a significant system, was forecast by the National Weather Service, which issued a Blizzard Warning on October 3, preceding the storm.[1] The storm occurred as an early season blizzard, and, according to the Weather Prediction Center, was an event of a magnitude unseen for the past decade.[2] Many locations in Colorado, Nebraska, Montana, Wyoming, North Dakota, and South Dakota received near or over 10 inches (25 cm) of snow. Some areas in South Dakota received nearly 4 feet (1.2 m) of snow, with Silver City receiving 47 inches (120 cm). In many locations, there were high winds of over 50 miles per hour (80 km/h), with some locations reporting winds of nearly hurricane force, which is 74 miles per hour (119 km/h).[3]

November 28

December 2–5

On December 2, a Pacific storm system entered the Western United States, and it spread heavy rain and snow from the Pacific coast to the Rocky Mountains. As the storm continued to move east, high snow totals fell in its wake. Maximum reported snowfall totals in this area were found to have occurred in Idaho, Wyoming, and Montana, where 30 inches (76 cm) or greater were reported. High winds were widespread as well, with multiple locations in the mountainous regions of the western US reporting winds of greater than 60 miles per hour (97 km/h). As reported by the National Weather Service's Weather Prediction Center, the surface low reached its peak strength at approximately 6:00 UTC on December 3 while it was over western Wyoming, where a central pressure of 994 hectopascals (Template:Convert/mbar inHg) was observed.[4]

Late on March 25, a winter storm emerged off the coast of the Southeastern United States and began to undergo explosive intensification, becoming a bomb cyclone by March 26. Powered by moisture coming from the Gulf of Mexico, the storm quickly became an unusually powerful nor'easter 4 times the size of Superstorm Sandy, and reached a maximum low pressure of 954 millibars.[7] The system produced powerful sustained winds up to 89 mph, and wind gusts up to 119 mph, with unofficial amounts reaching 129 mph. After making landfall on Nova Scotia, the system weakened to a 960 mbar nor'easter on March 27, before weakening further to a 975 mbar storm on March 28. On March 29, the system deteriorated into a weak winter storm over Greenland, where it would remain for the next few days while slowly dissipating.
