Given the humidity levels, readings may feel as high as 107F. A second pocket of heat will lock in across Southern California and Arizona, where highs in Phoenix may reach 117F on Saturday.“It’s a pretty persistent pattern,” said Bob Oravec, a senior branch forecaster with the US Weather Prediction Center. “In some form it stays in place through next week. It changes every day a little bit, but pretty much remains through the end of the month.”Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

In addition, stagnant air under the large high-pressure system may crimp wind-generated power at peak times.Across the US, 89 daily high temperature records may be threatened, tied or broken on Saturday, according to the Weather Prediction Center. In addition, another 229 overnight heat records may fall or be shaken as well. On Sunday, Rapid City, South Dakota is forecast to reach 105F, which would set a new record. High overnight temperatures also drive energy demand by eliminating natural cooling, and can be a hazard to people, animals and some crops.While the central US bakes, much of the East Coast, including New York City, is set to remain relatively cool. The highs in Manhattan’s Central Park are forecast to reach 81F Saturday and 83F Sunday under sunny skies.“It’s good for us on the East Coast because we stay on the cool side of the pattern,” Oravec said. “Our days of 100-plus temperatures are gone, at least for the time being.” This advertisement has not loaded yet.Notice for the Postmedia NetworkThis website uses cookies to personalize your content (including ads), and allows us to analyze our traffic.
