Here's why you better get used to a smoky stubborn summer in much of America

Forecasters say the only break much of America can hope for anytime soon from eye-watering dangerous smoke from fire-struck Canada is brief bouts of shirt-soaking sweltering heat and humidity from a southern heat wave that has already proven deadly. Even then the smoke will likely come back to the Midwest and East. That’s because neither the 235 out-of-control Canadian wildfires nor the stuck weather pattern that’s responsible for this mess of meteorological maladies are stubbornly showing no signs of relenting for the next week or longer. That's what meteorologists at the National Oceanic and Atmospheric Administration’s Weather Prediction Center figure.
