This Heat Dome Could Last Weeks—Heres Why [nNErRjiPlid]
Just days after a record-breaking heat wave disrupted July 4th celebrations nationwide, a new heat dome is building over the Midwest and Plains — and this one could stick around much longer. Unlike last week's heat dome, which centered over the Ohio and Mississippi valleys, this one is building first over the western U.S. before surging into the north-central states early this week and expanding eastward. Widespread highs of 95-105°F are expected across the northern Plains and Upper Midwest, with AccuWeather RealFeel temperatures reaching a dangerous 105-115°F. Minneapolis has already hit 92°F, Indianapolis 93°F, Chicago 95°F, and Omaha 96°F this week — several cities could set new highs for the year. Rather than breaking down, forecasters say the heat dome is expected to restrengthen and could persist through much of the rest of July, bringing prolonged 90-105°F highs to cities including St. Louis, Kansas City, Minneapolis, Des Moines, and Denver. The heat dome is also suppressing rainfall beneath its core, raising concerns about worsening crop stress in areas already facing drought. 🌡️ In this video: Where and when the new heat dome is hitting hardest How this compares to last week's record-breaking heat Why it could last through the rest of July How to stay safe during prolonged extreme heat #HeatDome #Midwest #ExtremeHeat #WeatherNews #Heatwave2026 Want to create live streams like this?
