Yellowstone's climate is greatly influenced by altitude, with lower elevations generally found to be warmer year-round. The record high temperature was {{convert|99|°F|°C}} in 2002, while the coldest temperature recorded is {{convert|-66|°F|°C}} in 1933.<ref name="facts"/> During the summer months of June to early September, daytime highs are normally in the {{convert|70|to|80|F|C}} range, while nighttime lows can go to below freezing (0&nbsp;°C), especially at higher altitudes. Summer afternoons are frequently accompanied by [[thunderstorm]]s. Spring and fall temperatures range between {{convert|30|and|60|F|C}} with nights in the teens to single digits (−5 to −20&nbsp;°C). Winter in Yellowstone is accompanied by high temperatures usually between {{convert|0|and|20|°F|°C}} and nighttime temperatures below {{convert|0|°F|°C|abbr=on}} for most of the winter.<ref name="weather">{{cite web |title=Weather |publisher=National Park Service |date=December 20, 2006 |url=http://nps.gov/yell/planyourvisit/weather.htm |access-date=March 20, 2007 |url-status=live |archive-url=https://web.archive.org/web/20070315015907/http://www.nps.gov/yell/planyourvisit/weather.htm |archive-date=March 15, 2007 }}</ref>

Precipitation in Yellowstone is highly variable and ranges from {{convert|15|in|mm}} annually near Mammoth Hot Springs, to {{convert|80|in|mm}} in the southwestern sections of the park. The precipitation of Yellowstone is greatly influenced by the moisture channel formed by the [[Snake River Plain]] to the west that was, in turn, formed by Yellowstone itself. Snow is possible in any month of the year, but most common between November and April, with averages of {{convert|150|in|mm}} annually around Yellowstone Lake, to twice that amount at higher elevations.<ref name="weather"/>

The climate at Yellowstone Lake is classified as [[Subarctic climate|subarctic]] (Dfc), according to [[Köppen-Geiger climate classification system|Köppen-Geiger climate classification]], while at the park headquarters, the classification is [[Humid continental climate|humid continental]] (Dfb).

[[Tornado]]es in Yellowstone are rare; however, on July 21, 1987, the most powerful tornado recorded in Wyoming touched down in the [[Teton Wilderness]] of [[Bridger-Teton National Forest]] and hit Yellowstone National Park. Called the [[Teton–Yellowstone tornado]], it was classified as an [[Fujita Scale|F4]], with wind speeds estimated at between {{convert|207|and|260|mph|km/h}}. The tornado left a path of destruction {{convert|1|to|2|mi|km}} wide, and {{convert|24|mi|km}} long, and leveled {{convert|15000|acre|ha sqmi}} of mature pine forest.<ref name="tornado">{{cite web |title=Severe Weather |publisher=Wyoming Climate Office |date=March 14, 2007 |url=http://www.wrds.uwyo.edu/wrds/wsc/climateatlas/severe_weather.html |access-date=March 20, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070219011836/http://www.wrds.uwyo.edu/wrds/wsc/climateatlas/severe_weather.html |archive-date=February 19, 2007 }}</ref>
