November 13–21, 2014 North American winter storm
From November 13–21, 2014, a potent winter storm and particularly severe lake-effect snowstorm affected the United States, originating from the Pacific Northwest on November 13, which brought copious amounts of lake-effect snow to the Central US and New England from November 15 until November 21, when the system departed the East Coast of the United States. The snowstorm elicited an enormous response from emergency crews and the National Guard, requiring more manpower than any other snowstorm in the history of New York state as it buried cars and stranded thousands of people in their homes in Western New York. Eight months after the storm, the snow's remnants still remained in Buffalo, New York.
Meteorology
The winter storm was associated with the November 2014 North American cold wave. On Thursday, November 13, an extratropical disturbance developed just off the shore of southern Oregon, at the end of an occluded front. Early on Friday, November 14, the system fully moved ashore in the Pacific Northwest, and began bringing snowfall to the region. The winter storm quickly moved southeastward and then northeastward, triggering large amounts of lake-effect snow near the Great Lakes beginning on Sunday, November 16. On November 16, Lake Erie had a water temperature of. On Monday, November 17, the system reached Western New York, triggering large amounts of lake-effect snow there as well. The air crossing over the lake by the evening of November 17 was at 850 hectopascals at the eastern end of the lake and even colder at its western end; this lapse rate was nearly double that of the dry adiabatic lapse rate and resulted in a very unstable atmosphere at the lower levels. The surface and lower-level winds were also well-aligned with the fetch of Lake Erie, favoring the formation of a long, intense band of lake-effect snow, and varied little over the next several days, keeping the band in place over the same areas for an extended period. The event was briefly interrupted by a low-pressure system with general snowfall passing through on Thursday, November 20, before reverting to the same synoptic setup as before.High pressure and warmer temperatures moved into the area beginning on Friday, November 21, which caused the storm to exit the East Coast, ending the lake-effect snow. The system then quickly began moving northeastward. During the next couple of days, the winter storm eventually intensified, On November 24, the storm decayed into a disorganized 986 mbar system, after moving just east of southern Greenland. On November 26, 2014, the weakened winter storm was absorbed by another neighboring system to the northwest of Iceland.
Impact
Several counties were heavily impacted, with areas in and around Buffalo, New York, particularly the city's southern suburbs, receiving snowfall totals in the range of, killing at least 26 people; most of the deaths were caused by heart attacks from overexertion trying to remove the snow. Under the sheer weight of the snow, roofs began collapsing. As the New York State Thruway became impassable, many motorists became trapped, including Niagara University's women's basketball team. With a forecast for warmer temperatures and rain, fears of potentially severe flooding due to the melting snow quickly arose. The maximum snowfall recorded from the storm was in the hamlet of Cowlesville, in the Town of Bennington in Wyoming County and bordering Erie County.Radio station WWKB was knocked off the air due to the event, but other radio and television stations were mostly unaffected, as their studios were located outside the snowbelt; those with news bureaus went wall-to-wall with coverage for the entire week and contributed reports to the national networks. WBEN prepared for the event by making sure those of its reporters who lived in the southern suburbs found accommodations north of the city before the event, ensuring they could make it to the station when the storm hit.
Many local school districts in and around Buffalo closed for more than a week in order to remove snow and assess possible damage to property.
