Across America's midwestern states, the weather is often unpredictable as very hot summers, winter blizzards and violent thunderstorms are not uncommon, and Iowa is no exception to that rule.
For the most part here the spring months are pleasant, but rainy; summers can be rather warm; fall months are comfortably mild, yet chilly in the mornings, and winters are cold statewide.
Early evening thunderstorms are common in late spring and summer, and tornados commonly occur in Iowa as it's positioned in America's Tornado Alley.
January is the coldest month, with average high temperatures in the high 30's. July is the warmest month, with average high temperatures approaching the high 80's. Hotter summers and colder winters (with significant snow) are not uncommon.
Annual precipitation amounts range from 25 to 30 inches in the northwestern third the state, while the central and southern areas are closer to 35 inches.
