The 2014–15 North American winter was frigid and prolifically wintry, especially across the eastern half of North America in the months of January–March. The season began early, with many places in North America experiencing their first wintry weather during mid-November. A period of below-average temperatures affected much of the contiguous United States, and several records were broken. An early trace of snowfall was recorded in Arkansas.[1] There were greater accumulations of snow across parts of Oklahoma as well.[2] A quasi-permanent phenomenon referred to as the polar vortex may have been partly responsible for the cold weather. Temperatures in much of the United States dropped 15 to 35 °F (8.3 to 19 °C) below average by November 19, following a southward "dip" of the polar vortex into the eastern two-thirds of the country. The effects of this dip were widespread, bringing about temperatures as low as 28 °F (−2 °C) in Pensacola, Florida.[3] Following a significant snowstorm there, Buffalo, New York received several feet of snow from November 17–21.[4] In addition, significant winter weather occurred throughout the season, including a major blizzard that struck the Northeastern United States at the end of January, another blizzard that affected much of the Northern United States days later in early February, and several significant snow events paired with very frigid temperatures for much of February.
Many records for snowfall and temperature were broken, many for the month of February, with every state east of the Mississippi River being colder than average, some for the entire winter. However, this meteorological winter was the 19th-warmest of the past 120 winters over the Contiguous United States, largely due to persistent warm weather in the Western United States.[5] During the 2014–15 winter season, Boston broke its all-time official seasonal 107.6-inch (2.73-meter) snowfall record from the winter of 1995–96, with a total snowfall record of 108.6 inches (2.76 m) as of March 15, 2015.[6]
While there is no well-agreed-upon date used to indicate the start of winter in the Northern Hemisphere, there are two definitions of winter which may be used. Based on the astronomical definition, winter begins at the winter solstice, which in 2014 occurred on December 21, and ends at the March equinox, which in 2015 occurred on March 20.[7] Based on the meteorological definition, the first day of winter is December 1 and the last day February 28.[8] Both definitions involve a period of approximately three months, with some variability.
Seasonal forecasts
On October 16, 2014, the National Oceanic and Atmospheric Administration's Climate Prediction Center issued its U.S. Winter Outlook. This outlook indicated that below-average temperatures in parts of the south-central and southeastern United States would be favored, with above-average temperatures favored in the western U.S., Alaska, Hawaii, and New England. Drought conditions were expected to improve in California's southern and northwestern regions, but no improvements were expected earlier than December or January. Above-average conditions were also expected to pervade the winter months in the western U.S., the Intermountain West extending across the U.S.–Canada border through New York and New England, and Alaska and Hawaii. The Precipitation Outlook favored above-average precipitation across the southern tier and Atlantic coast of the United States, with above-average precipitation also favored in southern Alaska and the Alaska panhandle. Below-average precipitation was favored in Hawaii, the northwestern United States, and near the Great Lakes region. The rest of the country was given an "equal chance" for either above- or below-average temperatures and/or precipitation.[9]

Seasonal summary
The North American winter season of 2014–15 expressed a significant level of variance. First,
Due to a persistent stationary high-pressure pattern over the west coast that redirects the jet stream, it remained (and remains) in a wavy ideal configuration to bring warm air north over the western U.S. and cold air towards the south over the continental states, and to favor winter storms over the East Coast. Severe winter blizzards over New England are often associated with this configuration, and nearly all of the snow storms this season followed very similar tracks and had marked similarities in their synoptic evolution. Boston in particular saw the effects of this, experiencing six major snow storms in the first two months of the year, leaving it with over 105 inches (270 cm) of snow. January 27 saw first major snowfall of 2015, with observations showing a blocked flow with warm air over the west coast, accompanied by a pronounced cold trough downstream, which pattern looks very similar to the blizzard that Boston saw on January 23, 2005.[18]
As a result, February was record-breaking for many cities in the United States, yet in opposite extremes. Much of February saw below-average cold in the eastern part of the country, it was markedly warm in the West. A multitude of cities east of the Mississippi experienced their coldest February in decades, including Chicago, Ill.; Cleveland, Oh.; Grand Rapids, Mich.; Harrisburg, Pa.; Hartford, Conn.; and Portland, Maine. Marquette, Mich. Syracuse, Buffalo and Rochester, N.Y. also set records for coldest month overall,[19] as did Bangor, Maine where the average temperature was 6.1 °F (−14.4 °C). And with an average temperature of 2.5 °F (−16.4 °C), the state of Maine itself also set a record low. For Worcester, Mass, February was the coldest month out of any month on record with an average temperature of just 14.2 °F (−9.9 °C), while also accumulating more than 110 inches (280 cm) of snow this winter.
In contrast, in the West a persistently strong ridge of high pressure over the warm eastern Pacific Ocean and western North America elevated temperatures to record levels from Arizona to Washington. It was the warmest winter month (December, January, February) on record in San Francisco; Seattle; Portland, Ore.; Reno, Nev.; Las Vegas; and Salt Lake City, with the latter realizing an average temperature for February of 43.9 °F (6.6 °C), breaking the old record set in 1907. Meanwhile, just 1.1 inches (2.8 cm) of snow fell in the entire month in Anchorage, Alaska, making it the fifth-least-snowy February on record.[20]
Portland and Salem had their warmest February on record, with the latter tying the record set in 1934 for their warmest at 45.9 °F (7.7 °C) degrees with the year. For the first time in record keeping, every day in February was at least 50 °F (10 °C) in Salem.[21]
California averaged 1.5 °F (0.83 °C) warmer than the previous warmest winter (2013–14), which had broken the previous record (1980–81) by 0.8 °F (−17.3 °C). February was the warmest on record in Washington, California, Utah and Arizona, while February was among the top 10 warmest in four other states. Overall, the National Oceanic and Atmospheric Administration reported that about 30.6 percent of the country was "very warm" – meaning February was in the warmest 10 percent of the historical record – while 31.5 percent of the country was "very cold," or in the coldest 10 percent historically.[5]

On December 9, 2014, ahead of a system moving onto the California coast, the National Weather Service issued several watches and warnings, including a Gale Warning, a Flash Flood Watch, a High Wind Watch, and a Hazardous Seas Advisory.[30] The storm complex brought heavy rain and snow to much of California. On hillsides scorched by wildfires, the rains brought down mud and rocks which covered part of California State Route 91.[31] The system brought from about 10 inches (25 cm) to over 2 feet (61 cm) of rain in some areas. High snowfall totals were recorded as well, with a maximum snowfall of 19.8 inches (50 cm) near Lodgepole, California. Recorded gusts of hurricane-force were recorded in California, Nevada, Oregon, and Washington, with a peak gust of 139 miles per hour (224 km/h) recorded near Benton, Nevada.[32] On December 12, an EF0-rated tornado struck Los Angeles. It was the most significant Los Angeles tornado since 1983, when a tornado struck the Los Angeles Convention Center.[33] While the rain was not great enough to bring an end to the intense drought affecting the area, it did help to bring some places above average in terms of annual precipitation.[31]

On January 8, Estcourt Station, Maine was the coldest place in the United States with −38 °F (−39 °C). Montpelier, Vermont had a record low of −20 °F (−29 °C), and Jackson, Kentucky was −1 °F (−18 °C). Schools closed in Portland, Maine and Chicago. In New York City the temperature was 9 °F (−13 °C), with a wind chill of −2 °F (−19 °C). Even as far south as Mobile, the temperature reached 17 °F (−8 °C).[38] Nearly 2000 flights were delayed, and 500 cancelled. Washington, D.C. had delays when railroads froze. In Pittsburgh, two baby African penguins at the National Aviary had to go inside.[39]

A major winter storm occurred from January 31 – February 2, bringing blizzard conditions to the Chicago area with 19.3 inches (49 cm) of snow, being the fifth-largest snowfall in city history. Detroit received 16.7 inches (42 cm), the third-largest recorded total and largest storm in 40 years.[51] Over a foot of snow was reported in locations in Indiana, Iowa, Ohio, and Wisconsin.[52] At least 25 centimetres (9.8 in) of snow fell near Toronto.[53] Some parts of the Northeast received up to two feet of snow from this storm, as a heavy band of snow stalled over Southern New England. However, widespread amounts of between 10 and 15 inches were much more the norm.[54]

February cold wave
Throughout nearly the entire month of February, extreme cold plagued the eastern half of the nation. Multiple blasts of arctic air associated with the polar vortex dove into the Northeast, but the coldest was the shot of arctic air that brought the coldest air recorded over portions of the eastern Great Lakes in decades on February 15, and possibly over the entire forecast record.[56] Well below normal temperatures covered a large portion of the eastern United States and were expected to stay in place, with only slight moderation, through the rest of the month.[57] Through February 21, primarily on February 16 and February 20, over 600 record low temperatures were recorded in the eastern U.S., including all-time record lows and record lows for February.[58][19] As of February 15, Lake Erie had 94 percent ice cover[59] while Lake Superior and Lake Huron were over 80 percent covered, and Lakes Michigan and Ontario were between 50 and 60 percent iced over.[60]

From February 14–15, the Northeast experienced yet another winter storm, with Boston receiving over 12 inches (30 cm) of snow.[61] Other locations around Massachusetts received up to 22 inches (56 cm), bringing the total snowfall up to almost 6 feet (1.8 m) in some areas.[61] Residents of Boston and surrounding areas were urged to stay inside, due to the increasingly dangerous conditions.[61] There were numerous automobile accidents and roofs caving in throughout the Northeast and Midwest, and at least six people were confirmed dead.[62]
Parts of the central and southern U.S. received heavy snow and ice. Washington, D.C. received over 4 inches (10 cm) of snow and parts of the mid-South received 0.5 inches (1.3 cm) of freezing rain. The ice storm caused over 200,000 people to lose power.[63] A second winter storm hit the mid-South on February 25–26, bringing an additional 3 inches (7.6 cm) to 8 inches (20 cm) of snow much of North Carolina.[64]
Late February–early March winter storms
In the last week of February into the first week of March, four separate winter storms impacted areas from western Texas to the Northeast, all which included a messy swath of snow and ice.
The first winter storm occurred on the weekend of February 20–22. During this time period, a weak area of low pressure formed in the central parts of the U.S, and began to track eastward. Precipitation was at first relatively scattered, but as the day went on it began to blossom, reaching the
The second winter storm focused on the South and Southeast on February 25–26. A stationary front coalesced into an area of low pressure in the center of Louisiana, and moved to the east. Originally composed of all rain, snow began to break out on the northern side of the winter storm due to cold air beginning to penetrate into the Deep South. It consisted of wet snow, which would cause numerous power outages.[66] Heavy snowbands also began to set up, which was the result of heavy accumulations ranging from 6–12 inches (15–30 cm) in eastern North Carolina.[64] The winter storm also produced a small but potent line of thunderstorms in the Florida Peninsula, as such a tornado watch was issued. The system began to accelerate somewhat as it began to emerge off the Southeast coast early on February 26, as snow continued to fall into the southern parts of the Mid-Atlantic.
The third in the series of winter storms happened from February 28 into late March 1, and spread a swath of snow and ice from the High Plains to New England.[67] The system organized from an upper-level impulse associated with a developing southward dip in the jet stream, which led to the formation of a weak area of low pressure. This weak disturbance began to develop a stripe of snow from the Midwest to the Ohio Valley, and it began to push into the Northeast as the sluggish winter storm tracked to the east. Snowfall was sometimes heavy at times, with snowfall rates of up to 2 inches per hour, but didn't last long. Freezing rain also began to develop in the Mid-Atlantic, setting the stage for more ice accumulations. As the snow moved to the east, warm air began to run over the cold air in place over the Mid-Atlantic, and snow changed over to a mix of freezing rain and sleet by evening on March 1 in areas near Maryland and southern New Jersey. Ice accumulations ranged from 0.1–0.4 inches (2.5–10.2 mm), and snow totals 5–8 inches (13–20 cm) in a swath from the Midwest near Illinois to southern New England. The entire wintry mess moved off by mid-morning on March 2.[68]
The fourth and final winter storm came right on the heels of the previous system, and actually occurred in two phases, with the latter bringing record cold in its wake.[69] It occurred from March 3–5, and brought up to a foot of snow in the Northeast, while also causing multiple travel issues and/or delays. One such included a pileup on Interstate 65 in Kentucky, where some people were stranded for many hours.

Records
Northeastern United States
Nine states in the Northeast United States had one of their coldest January–March periods on record.[72] According to the National Oceanic and Atmospheric Administration, from February 1 to 28, 2015, 898 lowest minimum temperature records were broken and 91 were tied in the Northeastern United States. In addition, 736 records for the highest snow depth were broken and 138 were tied during the same period.[73]
Over a large portion of New England, February 2015 was the most extreme winter month observed in modern record keeping. Eastport, Maine was one of many places also seeing record snowfall, with 132.5 inches (337 cm) over five weeks. Snowflakes fell on 19 out of 28 days in the Boston, Massachusetts area, setting records in numerous locations with depths up to over 36.0 inches (91 cm) deep in certain places. Boston broke the previous record for the snowiest month by almost 24.0 inches (61 cm).[74]
With a total of 108.6 inches (276 cm) as of March 16, Boston broke its previous all-time winter season (July 1 through June 30) record of 107.6 inches (273 cm) set in 1995–96.[75] Previously Boston saw a record 30-day snowfall of 94.4 inches (240 cm) from January 24 – February 22, 2015. Other broken records included four calendar days with at least 12.0 inches (30 cm) of snow, and the fastest 72.0 inches (183 cm) snowfall in 18 days from January 24 – February 10, 2015, and the fastest 90.0 inches (229 cm) snowfall during 23 days, from January 24 – February 15, 2015. Overall, Boston saw three of its top seven heaviest snowstorms in just over two years. Record cold temperatures were involved as Boston failed to reach 40 °F (4 °C) for 43 consecutive days, from January 20 through March 3.[citation needed] Boston also spent the second longest amount of time below freezing in the city records at 15 days.[76]
Providence, Rhode Island saw its second snowiest season with 73.5 inches (187 cm), with February being their second all-time snowiest month with 31.8 inches (81 cm).[77]
Boston, Massachusetts, received 99.4 inches (252 cm) of snow for the
Baltimore (as measured at BWI), averaged below the freezing temperatures for first three months of 2015, making it the coldest start to any year there on record. January averaged 2.1 °F (1.2 °C) below normal, and February was the second-coldest on record, being 10.5 °F (5.8 °C) below normal, while March continued the chilly trend, finishing 3.9 °F (2.2 °C) below normal.[79]
In February 2015, nine states (Connecticut, Maine, Massachusetts, New Hampshire, New York, Ohio, Pennsylvania and Vermont) had their second coldest February.[80] New York and Vermont had its coldest first quarter on record in 2015.[81]
Western United States
Despite an intrusion of cold air near the end of the month, temperatures in the Western United States averaged above normal for December, with temperatures in much of the area averaging over 3 °F (1.6 °C) above normal. The greatest departures from normal occurred in the vicinity of southern Idaho, where temperatures in Pocatello averaged 32.2 °F (0.1 °C), the seventh-warmest December in the area's 72-year record. Salt Lake City, Utah observed a monthly average temperature of 37.3 °F (2.9 °C), 7 °F (3.8 °C) above average, making the month the third-warmest December on record for the city. Ontario, Oregon too experienced its third-warmest December on record, averaging 36.2 °F (2.3 °C), 8.4 °F (4.6 °C) above normal. Fresno, California observed its warmest December on record, with an average of 51.9 °F (11.1 °C). Mount Shasta experienced its second-warmest December on record, with an average temperature of 41.1 °F (5.1 °C), 6.0 °F (3.3 °C) above normal.[82]
California, Idaho, Nevada, Oregon, Utah, Washington, and Wyoming all experienced a top-10 warm January in 2015. California also experienced its fourth-driest January on record, receiving only 15 percent of its average precipitation for what would ordinarily be the wettest month of the year. San Francisco recorded no measurable precipitation in January for the first time on record, and as with the state, January is typically the wettest month of the year for the city.[83] As of March 27, 2015 snowpack in the Sierra Nevada was at a record low of eight percent of the historical average for April 1.[84] Winslow, Arizona recorded 1.11 in (28 mm) above the normal precipitation level for the month with 1.63 in (41 mm) of precipitation during the month of January. With 270 percent of the average monthly precipitation, Tucson, Arizona saw its fourth-wettest January in a 69-year record with 2.54 in (65 mm) of precipitation. With an average monthly temperature of 62 °F (16.7 °C) (4 °F (2.2 °C) above normal), Los Angeles experienced its sixth-warmest January in its 139-year record. Rock Springs, Wyoming saw its third-warmest January on record with an average temperature of 29 °F (−1.7 °C) for the month, 7.6 °F (4.2 °C) above the temperatures typically observed.[85]
Much of the Western United States, including Arizona, California, Nevada, Utah, and Washington, experienced its warmest winter on the 120-year record, and Idaho, Oregon, and Wyoming experienced one of their top-three warmest winters.[86]
Canada
In Quebec, Montreal experienced its coldest February on record with an extended cold spell and an average temperature of −15 °C (5 °F).[88]
On February 13,
By the end of April 2015, a record 550 centimetres (220 in) of snow fell on parts of the Prince Edward Island.[90]
By the end of February, the maximum extent of ice cover in the Great Lakes was 88.8%, the first time since the late 1970s that two consecutive winters had resulted in ice cover of greater than 80%.[91]
