Kansas City's weather features a continental climate typical of the central United States, with distinct four seasons.

Summers are hot and humid, while winters are cold and sometimes snowy. Spring and fall have mild weather but can be quite variable, especially in spring when tornadoes and thunderstorms are a concern. Based on official data from the National Oceanic and Atmospheric Administration (NOAA) and Kansas City weather sources, we will summarize the annual weather information.

Spring (March to May): Spring in Kansas City is a season of unpredictable temperatures. The average low in March is about 34-39°F, and the high is around 52-55°F. By April, the lows rise to about 45°F, and the highs reach around 64°F. In May, the lows are about 55°F, and the highs can reach 75°F, making it a great time for outdoor activities. Rain is frequent during spring, with March to May being the wet season in Kansas City. The average monthly precipitation is about 3-4.3 inches. Notably, spring marks the beginning of tornado season, and the Missouri-Kansas area where Kansas City is located is adjacent to 'Tornado Alley,' leading to several tornado warnings each year. It is important to register for the emergency alert system and have an evacuation plan in place.

Summer (June to August): Summers in Kansas City are hot and humid. July is the hottest month, with average high temperatures reaching about 91-95°F. The high humidity can make it feel even hotter. From June to August, the average monthly precipitation is about 3.1-4 inches, with sudden thunderstorms often occurring in the afternoons. Excessive Heat Warnings are frequently issued during the summer, and special care is needed for the elderly, children, and outdoor workers. Kansas City's flat terrain has limited natural shade, making the heat feel more intense. Checking air conditioning systems and staying hydrated are essential during the summer.

Fall (September to November): Fall is one of the most pleasant seasons in Kansas City. The average high in September is about 82°F, dropping to 66°F in October and 52°F in November. Precipitation decreases compared to summer, and there are many clear days, making it ideal for enjoying fall foliage and outdoor events. October is a stable weather month and attracts many tourists. By mid-November, temperatures drop sharply, and the first snow begins to fall. Strong thunderstorms can still occur in the fall, and the weather can change quickly, so it's advisable to have outerwear ready.

Winter (December to February): Winters in Kansas City are cold and can be harsh at times. January is the coldest month, with average lows around 23-27°F and highs around 37-41°F. The average annual snowfall is about 18 inches, which is not as much as cities in the northeastern U.S., but there are days when snow accumulates each winter. Ice storms can occasionally occur, causing roads and sidewalks to freeze, prompting the city authorities to issue snow removal and road safety notices. Between December and January, heavy snow or ice storms can lead to school closures or traffic restrictions.

In summary, the average annual temperature in Kansas City is about 55°F, with annual precipitation around 37-38 inches. The average annual snowfall is about 18 inches, and the number of clear days per year is about 215, which is higher than the national average. Extreme weather events (tornadoes, heat waves, ice storms) occasionally occur, making preparedness essential. Setting up weather alerts for Kansas City on a smartphone app can help respond to sudden weather changes.

For Korean residents, compared to Seoul, Kansas City's summers are hotter and drier, while winters are similar or slightly milder. However, the spring tornado season and summer thunderstorms are weather phenomena that are difficult to experience in Korea, so newcomers are advised to sign up for local weather service alerts (NOAA Weather Radio, NWS app, etc.) and familiarize themselves with emergency evacuation procedures.
