Forecast

Effingham has a humid continental climate, with four clear seasons. Summers are usually warm and humid. Winters are cold, with some snow and ice. Spring and fall bring milder temperatures, but changes can happen quickly.

The area often gets weather from different air masses. Warm, moist air moves north from the Gulf of Mexico, while cold, dry air moves south from Canada. When these air masses meet, low pressure can bring rain, thunderstorms, and strong winds. High pressure usually brings calmer and drier weather.

Effingham sits on mostly flat land near the center of Illinois. It has no mountains to block winds or storms, so weather systems can move across the area easily. The flat farmland also allows large temperature changes between day and night.

Rain falls throughout the year, with heavier rain often occurring in spring and summer. Thunderstorms are common during the warmer months, and some can produce hail, damaging winds, or tornadoes. Snow is most likely from December through February, though winter amounts can change from year to year.
