Missouri generally has a variety of seasonal humid subtropical climate ( Köppen climate classification Cfa ), with cool winters and long, hot summers. In the southern part of the state, particularly in the Bootheel, the climate borders on a more mild - type humid subtropical climate ( Köppen Cfa ), and in the northern third, the state transitions into a humid continental climate ( Köppen Dfa ). Because of its location in the interior United States, Missouri often experiences extremes in temperatures. Lacking either large mountains or oceans nearby to moderate its temperature, its climate is alternately influenced by air from the cold Arctic and the hot and humid Gulf of Mexico. As of late, Missouri has seen a drastic decline in annual snowfall, with some daily high winter temperatures sometimes dwindling in early summer / late spring temperatures.

Although the mean temperature for June and July is only 73 ° F and 76 ° F ( 23 ° C and 24 ° C ) it is not uncommon for the temperature to reach 100 ° F ( 38 ° C ) at least three concurrent days each week in these months, as it did in 1904 during the World Fair where the temperature in St. Louis, Missouri was 103 ° F ( 39 ° C ).
