The climate of Missouri (United States of America)
The state of Missouri is centrally located in the United States. When the state was founded in 1821 it became the 24th state of the United States. The landscape of Missouri consists of hills and a rolling countryside. Missouri is located in a region where a warm maritime climate (type Cfa according to the Köppen climate classification) changes into a slightly more erratic warm continental climate (type Dfa). Extreme weather conditions are not uncommon in Missouri. This is because of the absence of protecting mountains, which makes it possible for cold air coming from the north and warm air coming from the Gulf of Mexico to reach the city. During the winter there may be mild days. However, when a northern current supplies cold Arctic air temperatures may drop below zero. This mainly occurs in December, January and February when subzero temperatures may also occur during the day. On average Missouri gets 10-15 centimeters of snowfall per year which falls in 7-10 days. However, during some winters hardly any snow falls while during other years heavy snowfall can be recorded. Summers are very warm. In June, July and August temperatures around or even above 30 degrees Celsius (86 degrees Fahrenheit) are not uncommon. Even in September temperatures may reach tropical values. Missouri is located in Tornado Alley which is a large region in the United States where tornadoes may form. These tornadoes can be very destructive. On Sunday 22 May 2011 the city of Joplin got hit by a category EF-5 multiple vortex tornado. During this tornado about a third of the city was destroyed and 159 people lost their lives. This made it the most deadly.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The figures below apply to Jefferson. For climate figures on specific regions and places please, visit the relevant individual climate pages.
