Weather of 2009 Winter of 2009–10 in Europe
The 2009–10 North American winter was one of the most active and prolific winter seasons on record in the United States and North America as a whole, and the most severe since the 1995–96 winter. Multiple winter storms and widespread arctic blasts throughout the winter led to an expansive snow cover, with the Weather Prediction Center (WPC) issuing summaries on a total of 20 significant winter weather events. None other that saw the most impacts was the Northeast and Mid-Atlantic states; from mid-December to the end of February, the region saw four blizzards affect a majority of the states, three of which occurred within the month of February alone. Those three storms pushed cities such as Washington D.C., Baltimore, Philadelphia and New York City to one of, if not the snowiest February on record. The winter also saw a prolific amount of winter storms rated on the Regional Snowfall Index (RSI) scale, with 17 such storms, and 6 of those storms further achieving a ranking of Category 3 or higher. A moderate-to-strong El Niño influenced the majority of the weather patterns during the winter, especially in the second half.
Other major winter weather events during the season also included a powerful West Coast storm in mid-October and a wide-ranging and crippling blizzard that struck the central U.S. on Christmas Eve and Christmas Day, spreading snow and blizzard conditions from Oklahoma to the Canada–United States border; it was also the first to be rated a Category 5 on the RSI scale since the January 1996 United States blizzard. In January, a a parade of storms caused significant impacts to the West Coast in addition to British Columbia in Canada. Additionally, a crippling Category 4 winter storm affected the southern half of the U.S. in mid-February, leading to record snow cover in those areas. Collectively, the winter storms and related weather caused at least $3.08 billion in damages and 108 fatalities, most of the deaths coming from the February 5–6 blizzard.
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 2009 occurred on December 21, and ends at the March equinox, which in 2010 occurred on March 20.Earth's Seasons: Equinoxes, Solstices, Perihelion, and Aphelion, 2000-2025 http://aa.usno.navy.mil/data/docs/EarthSeasons.php United States Naval Observatory March 27, 2015 August 15, 2015 Washington, D.C.

On October 15, 2009, the National Oceanic and Atmospheric Administration's Climate Prediction Center issued its U.S. Winter Outlook. Due to a strengthening El Niño, winter weather was expected to be affected by this. Warmer-than-average temperatures were favored across much of the western and central U.S., especially in the north-central states from Montana to Wisconsin. Below-average temperatures were expected across the Southeast and mid-Atlantic from southern and eastern Texas to southern Pennsylvania and south through Florida. Above-average precipitation is expected in the southern border states, especially Texas and Florida. Recent rainfall and the prospects of more should improve current drought conditions in central and southern Texas. The rest of the country fell into the equal-chance zone.NOAA: El Niño to Help Steer U.S. Winter Weather http://www.noaanews.noaa.gov/stories2009/20091015_winteroutlook.html National Oceanic and Atmospheric Administration October 15, 2009 April 27, 2016 December 19, 2015 https://web.archive.org/web/20151219170553/http://www.noaanews.noaa.gov/stories2009/20091015_winteroutlook.html live

The winter of 2009–10 was one of the most severe winter seasons on record for North America, with significant winter storms and arctic outbreaks of bitterly cold temperatures.https://www.ncei.noaa.gov/pub/data/cmb/images/remove-temp-sr/2009-2010-cold-season/2009-2010_Cold_Season.pdf 2009/2010 Cold Season National Oceanic and Atmospheric Administration December 14, 2010 January 10, 2026 affecting the majority of the continent and the United States during the majority of the winter months. At one point during the winter, on February 18, all of the Lower 48 had snowfall on the ground, signifying the extremity of the amount of major winter storms that occurred in a short period of time across the U.S. The extreme activity was also indicated by the high amount of storms rated on the Regional Snowfall Index (RSI); a total of 17 storms were rated on the scale, 6 of which were rated at or above a Category 3 on the scale. The ongoing 2009–10 El Niño event was responsible for the overall winter weather pattern, leading to many blockbuster snowstorms across the eastern half of the country. The season overall opened with a snowstorm in the Rocky Mountains at the start of October, before a major storm system, partially attributed to the remnants of Typhoon Melor, affected the Western United States by mid-month starting on October 13.Jeff Masters Weather Underground October 14, 2009 October 14, 2009 Thirsty California soaks up Melor's Deluge http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=1350 October 16, 2009 https://web.archive.org/web/20091016221845/http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=1350 dead November did not feature much activity, aside from the remnants of Hurricane Ida becoming a nor'easter that affected the Mid-Atlantic region mid-month, causing significant damage and heavy rainfall. Additionally, snow cover across the contgiuous U.S. was well-below average for the month of November, with temperatures mostly above average.

December saw a major pattern shift as winter weather events kicked into high gear, precipitated by the negative phases of the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO), which favor colder temperatures and more favorable winter storm tracks. Temperatures overall during the month of December were below-average as multiple outbreaks of cold temperatures affected the U.S.; the month ended with temperatures 3.2 °F (1.78 °C) colder than the long-term average nationally, with the coldest temperatures towards the central part of the country.NOAA National Centers for Environmental Information Monthly National Climate Report for December 2009 January 2010 January 10, 2026 https://www.ncei.noaa.gov/access/monitoring/monthly-report/national/200912 May 14, 2025 https://web.archive.org/web/20250514160436/https://www.ncei.noaa.gov/access/monitoring/monthly-report/national/200912 live A major winter storm affected regions from the Rocky Mountains to the Great Lakes from December 7–11, causing significant impacts. Only a week later on December 19, the first high-impact and major snowstorm for the eastern U.S. occurred, as a powerful blizzard buried the Northeastern United States under 12–24 in cm on of snow and killing 7. Shortly afterwards, on Christmas Eve, most of the Central United States were struck by an extremely large and widespread blizzard and storm complex that produced heavy snowfall and blizzard conditions from Texas and Oklahoma all the way north towards the Canada–United States border; the storm was rated a category 5 on the RSI, the first since the January 1996 blizzard. On Christmas Day, approximately 63% of the Contiguous United States had snow on the ground and constituting a "white Christmas", the most expansive snow cover since 2003; New York City and Philadelphia would not see another white Christmas after this winter until 2024.https://weather.com/storms/winter/news/2025-12-16-weirdest-white-christmas-2025 The Strangest White Christmases In US | Weather.com December 22, 2025 weather.com March 7, 2026 December 18, 2025 https://web.archive.org/web/20251218195153/https://weather.com/storms/winter/news/2025-12-16-weirdest-white-christmas-2025 livehttps://www.fox29.com/news/when-was-last-time-philadelphia-had-white-christmas When was the last time Philadelphia had a white Christmas?

A weak disturbance that started overnight on December 6 stalled over the western United States and intensified rapidly. Heavy downpours began early in the morning of December 7 and continued non-stop until the evening, triggering flash-flood watches. The storm dropped as much as 4.5 in mm on of rain in Cuyamaca, San Diego, causing blackouts in some locations. This storm was followed by a small semi-tropical winter storm which started overnight on December 10 and then stalled over Southern California and intensified, causing heavy downpours. In addition to 4 in mm of rain, this storm gave pea-sized-hail and gusty winds before weakening and moving away from Southern California on December 13. Heavy snow hit Wisconsin, New York, Washington, D.C., and parts of Maryland on the 10th and 14th. Heavy rain hit parts of Arizona on the 11th. In Vancouver, BC a strong winter storm deposited anywhere from 10 to 30 cm of heavy snow from the night of the 12th through to the morning of the 15th after a frigid arctic air that had been over the region for days with as low as -15 °C temperatures met with moist Pacific air.

2009 North American Christmas blizzard
Just before Christmas of 2009, an area of low pressure formed in eastern Texas, and began to track on a northwards track. Interacting with cold air from the west, snow broke out on the western side of the system, stretching from Oklahoma to southern Minnesota.

In late January, a winter storm affected the upper parts of the Southeast, specifically in the Carolinas. Originating from a weak area of low pressure that had formed from a large upper-level low in the Central U.S. late on January 29, it began to track to the east, and due to interacting with cold air that was in place over the Northeast, snow began to form around the North Carolina–South Carolina border, with heavy snowfall beginning to creep northwards.http://www4.ncsu.edu/~nwsfo/storage/cases/20100129/ January 29–30, 2010 Winter Storm March 7, 2026 November 14, 2018 https://web.archive.org/web/20181114210122/http://www4.ncsu.edu/~nwsfo/storage/cases/20100129/ live As the system moved towards the East Coast, snowfall rates began to increase to 1–2 in cm per hour. The storm began to accelerate, and began to crank out the last burst of snowfall along the affected areas before moving offshore. Total snowfall accumulations ranged from 8–14 in cm, mainly in North Carolina. Snowfall was even reported as far north as southern New Jersey, and a thick band of ice accumulations of up 0.4 in mm was also reported further south. 13 people were confirmed to have bene killed as a result of the storm.Annual Global Climate and Catastrophe Report: Impacting Forecasting - 2010 https://www.aon.com/attachments/reinsurance/201012_if_annual_global_climate_cat_report.pdf https://web.archive.org/web/20250110225623/https://www.aon.com/attachments/reinsurance/201012_if_annual_global_climate_cat_report.pdf January 10, 2025 March 7, 2026 aon.com
February cold wave
Another outbreak of arctic air occurred in February, persisting for most of the month, which allowed for many winter storms to affect the United States and North America as a whole in short succession.February 2010 Monthly Climate Reports https://www.ncei.noaa.gov/access/monitoring/monthly-report/national/201002 March 7, 2026 National Centers for Environmental Information (NCEI) Very cold temperatures were recorded as far south as the Gulf Coast, and the national average temperature in the United States for the month of February ended up slightly below average as a result. Temperatures below 0 F C were observed in rare locations due to expansive snowpack, with the town of Louisa, Virginia reaching a temperature of -3 F C on February 7.
Early February blizzards
Two blizzards occurred in very close proximity in the Northeast during a timespan from February 5–11. This put many areas in the Northeast towards their snowiest winter on record. Both were rated on the Regional Snowfall Index, a Category 3 for the first, and a Category 2 for the latter. While having very similar snow totals in its aftermaths, the origins were very different. In total, the back-to-back snowstorms produced record snowfall amounts in some areas and even pushed areas towards their snowiest season on record. They were also mentioned in the media, with the first blizzard receiving unofficial names like "Snowmageddon", "Snowpocalypse" and such, with the latter receiving an unofficial name of "Snoverkill".

This was the first blizzard in February 2010 that had major and widespread impact in the Northeastern United States. The storm's center tracked from Baja California Sur on February 2, to the east coast on February 6, 2010, before heading east out into the Atlantic. Effects were felt to the north and west of this track in northern Mexico, California, and the southwestern, midwestern, southeastern, and most notably mid-Atlantic States. Severe weather, including extensive flooding and landslides in Mexico, and historic snowfall totals in every one of the Mid-Atlantic states, brought deaths to Mexico, New Mexico, Virginia, Pennsylvania, and Maryland.http://dcist.com/2010/02/comparative_snowpocalypse_analysis.php Welcome to Comparative Snowpocalypse Analysis 101 February 6, 2010 DCist February 8, 2010 live https://web.archive.org/web/20100209022207/http://dcist.com/2010/02/comparative_snowpocalypse_analysis.php February 9, 2010

Less than two days after the previous storm had left the East Coast, another significant snowstorm pummeled nearly the same areas, throwing off many people and delaying cleanup efforts from the first storm. This storm began as a classic "Alberta clipper", starting out in Canada and then moving southeast, and finally curving northeast while rapidly intensifying off the New Jersey coast, forming an eye, something that a blizzard in 2005 had done (ironically 10 years later, another severe blizzard did the same). The National Weather Service, in an interview with The Baltimore Sun's weather reporter Frank Roylance, likened this storm to a Category 1 hurricane. Forecasters told Roylance that "Winds topped 58 mph over part of the Chesapeake Bay, and 40 mph gusts were common across the region as the storm's center deepened and drifted slowly along the mid-Atlantic coast".https://www.baltimoresun.com/ Baltimore Sun March 6, 2026 The Baltimore Sun March 7, 2026 April 11, 2017 https://web.archive.org/web/20170411011830/http://touch.baltimoresun.com/ live Total snow accumulations from this system were generally about 15–30 mi km further north then the previous blizzard snow totals had been, with accumulations peaking around 28 in cm (one area in Maryland in the higher elevations, picked up nearly 62 in ft).

February 25–27, 2010 North American blizzard
Near the end of the month, another blizzard struck parts of New England, New York, New Jersey, and Pennsylvania. This storm was a complex combination of multiple systems, including an upper air low from the northern Great Plains states, and a surface low from the Gulf Coast states. As the surface low tracked northeast from the coast of North Carolina, the upper air low transferred its energy to it, eventually enabling the new storm to undergo rapid intensification near the shore of eastern Long Island. A strong blocking regime of high pressure over the Canadian Maritime provinces prevented the storm system from exiting to the east. This resulted in a cutoff low (not influenced by the predominant jet stream currents), which took a highly unusual track, retrograding west into New York state before looping back out to sea.http://forecast.weather.gov/product.php?site=NWS&issuedby=OKX&product=AFD&format=CI&version=7&glossary=1&highlight=off February 26, 2010 National Weather Service Area Forecast Discussion National Oceanic and Atmospheric Administration National Weather Service February 26, 2010 October 1, 2011 https://web.archive.org/web/20111001060745/http://forecast.weather.gov/product.php?site=NWS&issuedby=OKX&product=AFD&format=CI&version=7&glossary=1&highlight=off live Total snowfall accumulations were as high as 36 in cm in areas further inland, while New York City picked up 20.9 inches of snow.
