This Fourth of July, grills won’t be the only thing sizzling as millions across the US face potentially dangerous heat levels.
The summer started off unusually hot and is expected to remain so, with only brief moments of relief in the coming weeks. For Independence Day, much of the Lower 48 will experience summertime heat, with two large sections of the country facing temperatures far exceeding early July norms.
In parts of the West and southern US, temperatures will soar, with California and Oregon expected to see highs 10 to 15 degrees above normal on Thursday. Meanwhile, Texas, Oklahoma, and the Carolinas will face temperatures 5 to 10 degrees above their usual levels.
Heat Waves Across Regions:
- California and Nevada: Parts of California’s Central Valley will see highs in the 100s and 110s, while Southern California’s desert areas, along with Nevada and Arizona, could approach 115 degrees. Sacramento might hit 107 degrees, close to its record for the Fourth of July. Las Vegas could see temperatures around 112 degrees, nearing its record for Independence Day.
- Phoenix: Although not record-breaking, Phoenix will see temperatures about 7 degrees above its normal high of 107, marking the third consecutive day of temperatures exceeding 110 degrees.
- Pacific Northwest: Portland, Oregon, will experience mid-90s on Thursday, climbing to nearly 100 degrees on Friday, which is about 25 degrees hotter than normal.
- Southern US: Highs in the 90s will be widespread, with parts of Texas and Oklahoma reaching the low 100s. Dallas is expected to hit 101 degrees, making it the fourth consecutive day of triple-digit temperatures. Atlanta will reach 94 degrees, significantly higher than its typical 88 degrees for the Fourth of July.
Humidity and Heat Index: The heat in the South will be exacerbated by humidity, making it feel over 100 degrees for millions. This combination of high temperatures and outdoor holiday activities could result in heat-related illnesses without proper precautions.
Thunderstorms: In addition to the heat, thunderstorms are forecasted for parts of the Mississippi Valley and Midwest from the morning, with potential severe storms in Missouri, Kansas, Oklahoma, and Arkansas by afternoon and evening. These storms could bring damaging wind gusts, hail, heavy rain, and possibly tornadoes. Thunderstorms may also affect fireworks displays in Washington, DC, Philadelphia, and New York City.
Stay safe and take necessary precautions during this period of extreme heat and potential storms.
