Some all-time record heat could scorch portions of the United States on the weekend of July 11.This time, the western and central U.S. could see a widespread and significant heat wave, said AccuWeather senior meteorologist Alex Sosnowski in an online forecast. The heat wave is expected to develop and intensify from the Intermountain West to the northern Plains, NOAA's Weather Prediction Center said in an online forecast.Widespread triple-digit high temperatures are expected by the afternoon of Saturday, July 11, possibly reaching the 110-degree mark locally by Sunday afternoon, July 12. This will lead to numerous daily high, monthly, and even all-time temperature records, the Weather Prediction Center said.Forecasters say parts of the East should brace for another round of 90–100-degree after the weekend, forecasters say. AccuWeather meteorologists predict the extreme heat threat building across the northern Plains will expand east across the nation as the new heat dome moves toward the Midwest and Ohio Valley.This will bring a period of dangerous heat and humidity to the eastern United States beginning Tuesday, July 14, while extreme heat continues across the central and western U.S.High humidity will increase the risk of heat-related illnesses despite air temperatures being somewhat lower than the July 4th week heat wave.All-time records?High temperatures may not just shatter records for a particular day, but they could approach, tie or top the hottest temperatures on record for some locations in the Rockies and northern Plains, Weather.com said.Specifically, Salt Lake City could flirt with its all-time record of 107 degrees set on five different days, most recently on July 17 and Sept. 7, 2022, according to Weather.com.Billings, Montana, could see its first high in the 110s in 92 years of records dating to 1934, Weather.com said. That's just one of almost two dozen locations in eastern Montana and Wyoming that could flirt with their all-time record highs.Extremely hot daytime highs combined with potentially record-warm overnight lows will result in increasing heat stress, leading to widespread major to locally extreme heat risk. "This heat wave will quickly become dangerous to anyone without adequate cooling or hydration," the WPC said.Remember your heat safety!In many areas of the Plains, this heat will be especially dangerous as June temperatures have limited heat acclimation, the National Weather Service said. "Remember to protect yourself by limiting outdoor activity, hydrating, and ensuring access to A/C or cooling centers. Never leave children or animals unattended in vehicles!"
