EXPANSIVE HEAT WAVE ACROSS THE PLAINS, MIDWEST & SOUTHEAST
An expansive and dangerous heat wave is building eastward today, bringing widespread Major to Extreme HeatRisk from the Plains through the Ohio Valley, Southeast, and Mid-Atlantic.
Highs ranging from 95°F to 105°F with heat indices exceeding 105°F (up to 110°F in humid southern Texas). Lows remaining elevated in the mid-70s will offer minimal relief, compounding heat stress on the body.
