Heat Dome Keeps Much of U.S. in Triple‑Digit Heat as Ridge Shows Signs of Weakening

Dangerous heat is pushing heat‑index readings into triple digits and straining public health and power systems.

Overview

  • Widespread Heat Advisories and Extreme Heat Warnings remain in place across the Gulf Coast, Texas and parts of the West where heat indices are forecast to top 108°F and outdoor heat illnesses are a major concern.
  • Inland Texas and the Southwest are forecast to stay at or above 100°F for several days with local forecasts calling for prolonged triple‑digit highs and Heat Advisories through the middle of the week.
  • Scattered afternoon and evening storms are expected regionally, with the Storm Prediction Center placing parts of the Southeast in marginal to brief moderate risk for strong to severe storms that could bring gusty winds and isolated flooding.
  • Western wildfire danger and smoke are elevated as Red Flag Warnings and very high fire danger affect parts of Washington and nearby areas, creating air quality impacts for sensitive groups.
  • The National Hurricane Center is monitoring an Atlantic tropical wave with roughly a 50 percent chance of development over seven days but officials say it is not an immediate threat to U.S. land areas while a late‑week ridge shift could increase rain and storm chances in some regions.
