Extreme temperature fluctuations in the United States

Overview

The central and southern United States experienced a period of unseasonably warm, summer-like temperatures. Initial forecasts indicated highs in the mid-80s for parts of Minnesota and Iowa, with potential for temperatures to reach the 90s in the Mississippi and Ohio valleys.

This heatwave intensified, with dozens of locations forecast to hit record high temperatures. Highs in the 90s were expected as far north as Illinois and Indiana, affecting cities such as St. Louis, Detroit, and Cleveland.

Following this extreme heat, a potent cold front moved across the country, triggering dramatic temperature swings. In many locations, highs were projected to drop by more than 30 degrees, with some northern areas experiencing freezing overnight temperatures for the first time since spring. The transition also brought risks of multi-day flooding across Texas and the Plains.
