Straddling two major zones, the majority of the state, except for the southeastern corner, has a [[humid continental climate]] ([[Köppen climate classification]] ''Dfb''). The southern portion of the state has a [[humid subtropical]] climate. The largest city, [[Philadelphia]], has a [[humid subtropical climate]] (Köppen ''Cfa''). Summers are generally hot and humid. Moving toward the mountainous interior of the state, the winter climate becomes colder, the number of cloudy days increases, and snowfall amounts are greater. Western areas of the state, particularly locations near [[Lake Erie]], can receive over {{convert|100|in|cm}} of snowfall annually, and the entire state receives plentiful precipitation throughout the year. The state may be subject to severe weather from spring through summer into autumn. Tornadoes occur annually in the state, sometimes in large numbers, such as 30 recorded tornadoes in 2011; generally speaking, these tornadoes do not cause significant damage.<ref>[http://www.homefacts.com/tornadoes/Pennsylvania.html/] {{webarchive|url=https://web.archive.org/web/20150517123642/http://www.homefacts.com/tornadoes/Pennsylvania.html/|date=May 17, 2015}}</ref> {| class="wikitable" style="text-align:center;font-size:90%;" | | colspan="13" style="text-align:center;font-size:120%;background:#E8EAFA;" |Monthly Average High and Low Temperatures For Various Pennsylvania Cities (in °F) |- !
