lying north and east of the state, although major Arctic blasts can occasionally reach the state. Average January high temperatures range from around in some northern valleys to almost in St. George. Temperatures dropping below should be expected on occasion in most areas of the state most years, although some areas see it often (for example, the town of Randolph averages about fifty days per year with temperatures that low). In July, average highs range from about . However, the low humidity and high elevation typically leads to large temperature variations, leading to cool nights most summer days. The record high temperature in Utah was , recorded south of St. George on July 4, 2007, and the record low was , recorded at Peter Sinks in the Bear River Mountains of northern Utah on February 1, 1985. However, the record low for an inhabited location is at Woodruff on December 12, 1932. Utah, like most of the western United States, has few days of thunderstorms. On average there are fewer than 40 days of thunderstorm activity during the year, although these storms can be briefly intense when they do occur. They are most likely to occur during monsoon season from about mid-July through mid-September, especially in southern and eastern Utah. Dry lightning strikes and the general dry weather often spark wildfires in summer, while intense thunderstorms can lead to flash flooding, especially in the rugged terrain of southern Utah. Although spring is the wettest season in northern Utah, late summer is the wettest period for much of the south and east of the state. Tornadoes are uncommon in Utah, with an average of two striking the state yearly, rarely higher than EF1 intensity. One exception of note, however, was the unprecedented Salt Lake City Tornado that moved directly across downtown Salt Lake City on August 11, 1999. The F2 tornado killed one person, injured sixty others, and caused approximately $170 million in damage; it was the second strongest tornado in the state behind an F3 on August 11, 1993, in the Uinta Mountains. The only other reported tornado fatality in Utah's history was a 7-year-old girl who was killed while camping in Summit County on July 6, 1884. The last tornado of above (E)F0 intensity occurred on September 8, 2002, when an F2 tornado hit Manti. Wildlife Utah is home to more than 600 vertebrate animals as well as numerous
