How will it impact the DC region? [ygtXx2GhfFs] Health Updated on August 09, 2026 EDT — Published on August 09, 2026 EDT A heat dome is a ridge of high pressure that traps hot air like a lid on a pot, pushing temperatures roughly 30°F above normal and lingering for days. Instead of letting hot air rise and disperse, the high pressure pushes it back down, compressing and warming it further, while also blocking clouds and storms that might otherwise bring relief. The result: day after day of intensifying heat with little to break the cycle. 79aeyKiYnxP 4Cjo3exrNxx SWOpkCrJ3JN 0YbrNtwQLYa cQpgH3eFI3h 1yOg0L9rAGI
