Editing Worcester, Massachusetts (section)

===Climate===
Worcester's [[humid continental climate]] ([[Köppen climate classification|Köppen]]: ''Dfb'') is typical of [[New England]]. The weather changes rapidly owing to the confluence of warm, humid air from the southwest; cool, dry air from the north; and the moderating influence of the [[Atlantic Ocean]] to the east. Summers are typically hot and humid, while winters are cold, windy, and snowy. Snow typically falls from the second half of November into early April,<ref name = NOAA/> with occasional falls in October; May snow is much rarer. The [[United States Department of Agriculture|USDA]] classifies the city as straddling [[hardiness zone]]s 5b and 6a.<ref>{{cite web |title=USDA Plant Hardiness Zone Map |author=United States Department of Agriculture |publisher=[[United States National Arboretum]] |url=http://www.usna.usda.gov/Hardzone/hzm-ne1.html |accessdate=February 19, 2015 |authorlink=United States Department of Agriculture |archive-date=March 3, 2015 |archive-url=https://web.archive.org/web/20150303152208/http://www.usna.usda.gov/Hardzone/hzm-ne1.html }}</ref>

The hottest month is July, with a 24-hour average of {{convert|70.2|°F|1}}, while the coldest is January, at {{convert|24.1|°F|1}}. There are an average of only 3.5 days of highs at or above {{convert|90|°F|0}} and 4.1 nights of lows at or below {{convert|0|°F|0}} per year, and periods of either extremes are rarely sustained. The all-time record high temperature is {{convert|102|°F|0}}, recorded on July 4, 1911,<ref>{{cite web

Worcester is known for being particularly snowy in the cold months, sometimes even experiencing intense autumn blizzards. The city averages {{convert|48.07|in|mm|sigfig=3}} of [[precipitation (meteorology)|precipitation]] a year, as well as an average of {{convert|64|in|cm}} of snowfall a season,<ref>{{Cite web |title=Weather averages Worcester, Massachusetts |url=https://www.usclimatedata.com/climate/worcester/massachusetts/united-states/usma0502 |access-date=2023-12-19 |website=www.usclimatedata.com |language=en}}</ref> receiving far more snow than coastal locations less than {{convert|40|mi|km}} away.<ref>{{Cite web |last=Sami |first=Isabel |title=Why Worcester gets more snow than most |url=https://www.telegram.com/story/news/2021/02/01/storm-central-heres-why-worcester-gets-more-snow-than-most/4340701001/ |access-date=2023-12-19 |website=The Worcester Telegram & Gazette |language=en-US}}</ref><ref>{{Cite web |title=Weather averages Boston, Massachusetts |url=https://www.usclimatedata.com/climate/boston/massachusetts/united-states/usma0046 |access-date=2023-12-19 |website=www.usclimatedata.com |language=en}}</ref> Massachusetts' geographic location, jutting out into the [[North Atlantic]], as well as Worcester's elevation relative to the surrounding terrain, makes the city very prone to [[Nor'easter]] weather systems that can dump heavy snow on the region. Extreme winters have brought up to {{Convert|120|in|cm}} of snowfall, as happened in 2005. In late January 2015, a blizzard traversed over the city as it shed almost {{Convert|32|in|cm}} of snow. This was the highest single-day snowfall total for anywhere in Massachusetts since data collection began in 1892.<ref>{{Cite web |last=Stucker |first=Kyle |title=Record snowfalls: Here are the largest single-day snowstorms in Massachusetts history |url=https://www.wickedlocal.com/story/regional/massachusetts/2022/01/28/massachusetts-weather-winter-storm-total-history-blizzard-78/9241463002/ |access-date=2023-12-19 |website=Wicked Local |language=en-US}}</ref>

While rare, the city has had its share of extreme weather. On September 21, 1938, the city was hit by the brutal [[New England Hurricane of 1938]]. Fifteen years later, Worcester was hit by a [[1953 Worcester tornado|tornado]] that killed 94 people. The deadliest tornado in New England history, it damaged a large part of the city and surrounding towns. It struck [[Assumption Preparatory School]], now the site of [[Quinsigamond Community College]].
