List Of Regional Snowfall Index Category 4 Winter Storms
The Regional Snowfall Index (RSI) is a system used by NOAA to assess the societal impacts of winter storms in the United States. The scale is a replacement for the Northeast Snowfall Impact Scale (NESIS) system, which was used for winter storms just in the Northeastern United States; Regional Snowfall Index assesses winter storm impacts in the six easternmost regions of the United States instead of just the Northeast. Since its initiation, the NCDC has assigned RSI values to nearly 600 winter storms since 1900. Storms are ranked from Category 0 "Nuisance" to Category 5 "Extreme" on the scale. A Category 4 winter storm on the RSI scale is classified as "Crippling". The impact of the storms is assessed in six different regions of the United States: the Northeast, Northern Rockies and Plains, Ohio Valley, South, Southeast, and Upper Midwest. A Category 4 "Crippling" ranking is indicated by a numerical score between 10 and 18 on the scale. Out of the nearly 600 historical winter stor ...

February 1973 United States Blizzard
February is the second month of the year in the Julian calendar, Julian and Gregorian calendars. The month has 28 days in common years or 29 in leap years, with the 29th day being called the ''leap day''. It is the first of five months not to have 31 days (the other four being April, June, September, and November) and the only one to have fewer than 30 days. February is the third and last month of meteorological winter in the Northern Hemisphere. In the Southern Hemisphere, February is the third and last month of meteorological summer (being the seasonal equivalent of what is August in the Northern Hemisphere). Pronunciation "February" is pronounced in several different ways. The beginning of the word is commonly pronounced either as or ; many people drop the first "r", replacing it with , as if it were spelled "Febuary". This comes about by analogy with "January" (), as well as by a dissimilation effect whereby having two "r"s close to each other causes one to change. The ...

North American Blizzard Of 2005
The North American blizzard of 2005 was a three-day storm that affected large areas of the northern United States, dropping more than 3 feet (0.9 m) of snow in parts of southeastern Massachusetts, as well as much of the Boston metropolitan area. While this was by far the hardest hit region, it was also a significant snowstorm for the Philadelphia and New York City areas, which both suffered occasional blizzard conditions and snow accumulations. The storm began dropping snow on the upper Midwestern United States, Midwest on Thursday, January 20, 2005. It slowly moved eastward affecting the Great Lakes (North America), Great Lakes region and the Mid-Atlantic states on Friday and Saturday, January 21 and January 22, 2005. On Saturday evening the storm entered the Southern New England area. The strength of the storm, coupled with the extreme Arctic temperatures, created a light, fluffy snow which increased the snowfall totals. The storm shut down Logan International Ai ...

Climate Of The United States
The climate of the United States varies due to changes in latitude, and a range of geographic features, including mountains and deserts. Generally, on the mainland, the climate of the U.S. becomes warmer the further south one travels, and drier the further west, until one reaches the West Coast. West of 100°W, much of the U.S. has a cold semi-arid climate in the interior upper western states (Idaho to the Dakotas), to warm to hot desert and semi-arid climates in the southwestern U.S. East of 100°W, the climate is humid continental in northern areas (locations roughly above 40°N, Northern Plains, Midwest, Great Lakes, New England), transitioning into a humid temperate climate from the Southern Plains and lower Midwest east to the Middle Atlantic states (Virginia to southern Connecticut). A humid subtropical climate is found along and south of a mostly east–west line from the Virginia/Maryland capes (north of the greater Norfolk, Virginia area), westward to approximately ...

List Of Northeast Snowfall Impact Scale Winter Storms
The Northeast Snowfall Impact Scale (NESIS) is a scale used to categorize winter storms in the Northeast United States. The scale was developed by meteorologists Paul Kocin and Louis Uccellini, and ranks snowstorms from Category 1 ("notable") to Category 5 ("extreme"). Only two historical blizzards, the 1993 Storm of the Century and the North American blizzard of 1996 are rated in the 5 "extreme" category. The scale differs from the Saffir–Simpson Hurricane Scale and Fujita Scale, which are used to classify tropical cyclones and tornadoes, respectively, in that it takes into account the number of people affected by the storm. The scale, as devised, is intended chiefly to assess past storms rather than assist in forecasts.Kocin and Uccellini, pp. 269–270 List There are two available values for NESIS. The original values that Paul Kocin and Louis Uccellini computed for storms in their original 2004 work "A Snowfall Impact Scale Derived From Northeast Storm Snowfall Distr ...

List Of Regional Snowfall Index Category 5 Winter Storms
The Regional Snowfall Index (RSI) is a system used by NOAA to assess the societal impact of winter storms in the United States. The system is a replacement for the Northeast Snowfall Impact Scale (NESIS) system which, unlike the former; assesses winter storm impacts outside of the Northeastern United States. Since its initiation the NCDC has retroactively assigned RSI values to over 500 historical storms since 1900. Storms are ranked from Category 0 to 5 on the scale; with the former being classified as "Nuisance" and the latter as "Extreme". The impact of the storms is assessed in six different regions of the United States: the Northeast, Northern Rockies and Plains, Ohio Valley, South, Southeast and the Upper Midwest. A Category 5 ''Extreme'' ranking is indicated by a numerical score of 18 or higher on the scale. Out of the over 500 historical storms assessed since 1900, only twenty-six storms have been given a Category 5 ranking. The highest ranking storm on the list is the ...

March 2017 North American Blizzard
The March 2017 North American blizzard was a major late-season blizzard that affected the Northeastern United States, New England and Canada, dumping up to of snow in the hardest hit areas, mainly New York, Vermont, New Hampshire and Southern Quebec. Forming out of an extratropical cyclone near the Northwest, the storm system dived into the northern portions of the United States, dropping light to moderate snow across the Great Lakes, Upper Midwest on March 11–12 before reaching the Ohio Valley the next day. It later coalesced into a powerful nor'easter off the East Coast, producing a swath of heavy snowfall across a large portion of the Northeast. The storm was given various unofficial names, such as ''Winter Storm Stella'', ''Blizzard Eugene'', and ''Blizzard of 2017''. Ahead of the storm, residents prepared in advance for the major nor'easter, with blizzard warnings issued for several states, including New York, Pennsylvania, New Jersey, Connecticut, Rhode Island, and Mass ...

February 2014 Nor'easter
The February 2014 nor'easter was a major nor'easter that produced a damaging snow and ice storm that affected the Southern United States and East Coast of the United States, bringing with it up to a foot of snow and crippling ice across parts of the South. Thousands if not hundreds of thousands of people were left in the dark for days, possibly even up to 2 weeks without power. Delta Air Lines canceled over 2,000 flights, and it was reported by 8:00 p.m. Thursday, February 13, that as many as 6,500 flights originating in or destined for the United States had been canceled. On that day 70 percent of flights were cancelled at airports in Baltimore, Philadelphia, Washington, D.C., and Charlotte. Approximately 1.2 million homes and businesses lost power as the storm moved from the South through the Northeast. By the evening of Thursday, February 13, about 550,000 customers remained in the dark, mostly in South Carolina and Georgia. Meteorological history On February 11, a quick- ...

February 25–27, 2010 North American Blizzard
The February 25–27, 2010 North American blizzard (also known as the " Snowicane") was a winter storm and severe weather event that occurred in the Mid-Atlantic and New England regions of the United States between February 24–26, 2010. The storm dropped its heaviest snow of (locally as much as ) across a wide area of interior New England, New York, and Pennsylvania. The storm also brought flooding rains to coastal sections of New England, with some areas experiencing as much as . Aside from precipitation, the Nor'easter brought hurricane-force sustained winds to coastal New England. 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.

February 5–6, 2010 North American Blizzard
The February 5–6, 2010 North American blizzard, commonly referred to as ''Snowmageddon'', was a blizzard that had major and widespread impact in the Northeastern United States. The storm's center tracked from Baja California Sur on February 2, 2010, 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. Most crippling was the widespread 20 to 35 in (50 to 90 cm) of snow accumulated across southern Pennsylvania, the Eastern Panhandle of West Virginia, northern Virginia, Washington, D.C., Maryland, Delaware, and South Jersey, bringing air and interstate highway trav ...

December 2009 North American Blizzard
The December 2009 North American blizzard was a powerful nor'easter that formed over the Gulf of Mexico in December 2009, and became a major snowstorm that affected the East Coast of the United States and Canadian Atlantic provinces. The snowstorm brought record-breaking December snowfall totals to Washington, D.C., Baltimore, and Philadelphia. The blizzard disrupted several regions, and in some areas the snowfall rate prevented snow plows from maintaining the roads. The blizzard caused flights and trains to be canceled, and left areas without power. Kentucky, Maryland, Virginia, West Virginia, and New Castle and Kent counties in Delaware declared a state of emergency. Seven deaths were reported to have been caused by the storm. Meteorological history On December 16, 2009, meteorologists identified a storm forming in the Gulf of Mexico. It produced record rainfall in regions of Texas and had the potential to strengthen as it moved through Georgia and Florida and further nort ...

December 21–24, 2004 North American Winter Storm
December is the twelfth and final month of the year in the Julian and Gregorian calendars and is also the last of seven months to have a length of 31 days. December got its name from the Latin word ''decem'' (meaning ten) because it was originally the tenth month of the year in the calendar of Romulus which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.Macrobius, ''Saturnalia'', tr. Percival Vaughan Davies (New York: Columbia University Press, 1969), book I, chapters 12–13, pp. 89–95. In Ancient Rome, as one of the four Agonalia, this day in honour of Sol Indiges was held on December 11, as was Septimontium. Dies natalis (birthday) was held at the temple of Tellus on December 13, Consualia was held on December 15, Saturnalia was held December 17–23, Opiconsivia was ...
