Allen is in east central Kansas, on the open Great Plains. Its inland location brings large temperature changes. The area has hot summers, cold winters, and quick weather changes during spring and fall.
High pressure often brings clear skies, light winds, and dry air. Low pressure can bring clouds, strong winds, rain, and thunderstorms. In spring and early summer, warm, moist air from the Gulf of Mexico can meet cold, dry air from the north. This can cause heavy rain, hail, damaging winds, and sometimes tornadoes.
The flat to gently rolling land around Allen does not block air masses. Cold air can move south from Canada, while warm air can move north from the Gulf region. The area usually gets about 35 to 40 inches of rain each year, with much of it falling during spring and summer. Snowfall is usually light to moderate, but winter storms can still bring ice, strong winds, and heavy snow.
Summers are often hot, humid, and stormy. Fall usually brings cooler temperatures and calmer weather, though storms can still occur. Winters are cold, with changing periods of clear weather, rain, snow, and ice. Spring is mild to warm and has the greatest risk of severe storms. Local conditions can also include drought during dry periods and flooding after heavy rain.
