How will it impact the DC region? [lJ8B84SDZx4] Health Updated on August 07, 2026 EDT — Published on August 07, 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. YTCboLSOsnm y3LTT3O27Xj Te6YPCIYp3b IAgWuuyrvVv ic6Rxkbj1p5 w7B90i3oxG7 KMirG1hwplf
