  "textContent": "Extreme heat is expected to build across the Washington, D.C. region later this week, with temperatures climbing toward 100 degrees as the Fourth of July holiday approaches.\n\nMonday will be near seasonal, with highs in the 80s and mainly dry conditions. Patchy fog and low clouds early in the day may cause minor visibility issues for the morning commute, but most areas should see improvement by midday as sunshine breaks through.\n\nFOX 5’s Taylor Grenda says temperatures rise into the 90s on Tuesday before a heat dome settles over the mid‑Atlantic beginning Wednesday.
