Heat Advisories Affect Interstate 25 Corridor, Northern New Jersey, Nevada

A widespread heat wave is affecting multiple regions in the western and northeastern United States, with several areas forecast to reach or approach 100 degrees Fahrenheit this week. Fort Collins, Colorado, is expected to record its first 100-degree day of the year on July 9, marking a return to intense summer heat typical for mid-July. Las Vegas will experience highs consistently in the 108°-110° range, with a moderate heat risk for vulnerable populations and extreme UV index levels, while central Wyoming is forecast to see temperatures peak near 98 degrees before cooling slightly later in the week. Northern New Jersey, including Paterson, is under a heat advisory due to heat indices expected to reach between 100 and 104 degrees, prompting warnings for heat-related illnesses and the opening of cooling centers. Officials across these regions emphasize precautions such as hydration, limiting outdoor activities, and seeking air-conditioned environments to mitigate health risks associated with the heat. Weather forecasts also note potential thunderstorms in some areas following the heat peaks, offering some relief later in the week.
