A heat wave is happening in the US. See where it will be the hottest
A broad upper ridge is driving a dangerous heat wave across the Plains to the Southeast, with afternoon highs in the upper 90s to low 100s and some Desert Southwest spots reaching 115–120. Heat indices are expected to run well above 105–115 degrees in much of the central U.S. into Monday, with extreme heat warnings issued for several states. Officials warn that relief will begin to arrive Tuesday as thunderstorms and a cold front move in from the central Plains to the Midwest. Health guidance stresses avoiding peak sun, staying hydrated, and seeking air-conditioned spaces, given the risk of heat exhaustion and heat stroke. The outlook suggests gradual cooling northward as the week progresses, though heat remains hazardous in affected areas.

A dangerous heat wave is forecast to persist into early next week, driven by a broad upper ridge centered over the central and southern U.S., affecting the Plains through the Mississippi Valley and Southeast.
Afternoon temperatures are expected to climb into the upper 90s to low 100s, with isolated Desert Southwest locales reaching 115–120 degrees, and overnight lows may remain in the 70s.
Forecasters warn that heat indices could surpass 105–115 degrees due to the combination of high temperatures and humidity, prompting major to extreme heat risk levels in much of the central/southern Plains, Mississippi Valley, and Southeast.
Extreme heat warnings cover numerous states, including Arizona, California, Illinois, Iowa, Kansas, Mississippi, and Missouri, with conditions continuing through Monday evening.
Relief is forecast on Tuesday as thunderstorm activity increases in the central Plains and a cold front drops into the Midwest, limiting heat in northern areas.
Health guidance emphasizes scheduling outdoor activity for cooler times, dressing in lightweight clothing, staying hydrated, and limiting sun exposure; recognition of heat exhaustion and heat stroke symptoms is highlighted.
Key symptoms cited include headache, nausea, dizziness, confusion, and very high body temperature, underscoring the need for rapid action if conditions worsen.
