Heat Dome Triggers Severe Storms and Flooding in Northeast
A massive heat dome is currently affecting the Southeast and central United States, causing extreme heat and fueling severe storms in the Northeast and Great Lakes regions. Temperatures have exceeded 100°F (37.8°C) in states like Texas, Oklahoma, Kansas, Louisiana, and Arkansas over the past week, with heat indices reaching up to 110°F (43.3°C). Overnight lows are also unusually high, ranging 10–15°F (5.5–8.3°C) above average, with some areas experiencing temperatures 20°F (11.1°C) above normal. The heat dome, a high-pressure system trapping warm air, is obstructing the jet stream and creating conditions for severe storms. Heavy rainfall and flooding have already begun in parts of Pennsylvania, New York, and New Jersey, with more storms expected through Thursday. The situation is exacerbated by climate change, which has increased atmospheric moisture, leading to heavier downpours. [CNN, 2026]
