The urban area of St. Louis has a [[humid subtropical climate]] ([[Köppen climate classification|Köppen]]: ''Cfa''); however, its [[Greater St. Louis|metropolitan region]] even to the south may present a hot-summer [[humid continental climate]] (''Dfa''), which shows the effect of the [[urban heat island]] in the city. The city experiences hot, humid summers and chilly to cold winters. It is subject to both cold Arctic air and hot, humid tropical air from the [[Gulf of Mexico]]. The average annual temperature recorded at nearby [[Lambert–St. Louis International Airport]], is {{convert|57.4|°F|1}}. {{convert|100|and|0|°F|0}} temperatures can be seen on an average 3 and 1 days per year, respectively. Precipitation averages {{convert|41.70|in|mm|sigfig=2}}, but has ranged from {{convert|20.59|in|mm|abbr=on}} in 1953 to {{convert|61.24|in|mm|abbr=on}} in 2015. The highest recorded temperature in St. Louis was {{cvt|115|°F}} on July 14, 1954, and the lowest was {{cvt|-22|°F}} on January 5, 1884.

St. Louis experiences [[thunderstorm]]s 48 days a year on average.<ref name="weatherbase">{{cite web |url=http://www.weatherbase.com/weather/weatherall.php3?s=43427&refer=&units=us |title=Historical Weather for St. Louis, Missouri |access-date=October 15, 2009 |archive-url=https://web.archive.org/web/20120916194311/http://www.weatherbase.com/weather/weatherall.php3?s=43427&refer=&units=us |archive-date=September 16, 2012 |url-status=live}}</ref> Especially in the spring, these storms can often be severe, with high winds, large [[hail]] and tornadoes. Lying within the hotbed of [[Tornado Alley]], St. Louis is one of the most frequently tornado-struck metropolitan areas in the U.S. and has an extensive history of [[St. Louis tornado history|damaging tornadoes]]. Severe flooding, such as the [[Great Flood of 1993]], may occur in spring and summer; the (often rapid) melting of thick snow cover upstream on the Missouri or Mississippi Rivers can contribute to springtime flooding.
