A powerful upper-level heat dome is forecast to blanket Florida and the Southeast this weekend into next week, with highs in the mid-90s to around 100F and heat indices of 105–115F due to high humidity; NOAA says dozens of heat records could be broken and more than 30 million people will be under extreme heat, with the pattern persisting through next weekend.
An unusually intense heat dome is pushing dangerous, often triple-digit temperatures across the Western United States this weekend, with about 55 million people under heat alerts and highs forecast to reach as high as 118°F in Phoenix and 115°F in Las Vegas, among other hot conditions. Nights will remain warm, raising risks of heat-related illness, and cooling centers are opening in major cities like Los Angeles and Las Vegas. The heat is accompanied by extreme fire danger in the Pacific Northwest, where windy, dry conditions and ongoing wildfires prompt evacuations and smoke across several states. Scientists say climate change is making such hot spells more frequent, intense, and long-lasting.
A powerful heat dome blankets the Western U.S. this weekend, with about 55 million people under heat alerts from California, Nevada, and Arizona to the Canadian border. Temperatures are forecast to hit triple digits in many places (Phoenix up to 118°F, Las Vegas around 115°F, LA in the mid-90s), risking dozens of record highs and dangerous overnight heat. Cooling centers are open in major cities as health officials warn of heat-related illness. In the Pacific Northwest, extreme fire danger (Level 3) prompts evacuations near Spokane due to the Old Trails Fire, while wildfire smoke affects multiple states and Canada. Climate change is linked to more intense, longer-lasting heat waves like this one.
A record-breaking heat dome will blanket Southern California this weekend, driving inland highs into the 100s (with some spots near 110°F) aided by El Niño moisture from Hurricane Genevieve, while humidity drops and wildfire risk rises; the Central Valley and parts of Northern California will endure sustained triple-digit heat into next week, the coast will stay cooler, and air quality may dip as wildfire smoke drifts from Oregon as the dome lingers and then shifts.
More than 42 million people are under heat alerts across the U.S. as a westward-shifting heat dome drives temperatures to as high as 119°F near Tecopa, California. The National Weather Service warns of dangerous heat across the Southwest through the weekend, with heat indices around 120°F in parts of the desert Southwest and Gulf Coast. About 2 million people are at the highest risk and 24 million at major risk, with health guidance urging hydration, cooling, and limited outdoor activity. Relief is expected by week’s end as a cold front lowers highs by 10–20 degrees.
A high-pressure heat dome will push from the Texas Panhandle into the Southwest this week, lifting temperatures into the 100s and 110s, boosting wildfire risk and smoke across the West and into Canada, with air quality concerns especially in the Northwest and nearby regions.
A heat dome is trapping heat across the central United States, pushing temperatures above 100 F from the Southwest to the Midwest and leaving roughly 70 million people under heat advisories. Overnight lows will stay high, humidity will be oppressive, and vulnerable populations are at risk as the heat persists through the week with limited relief anticipated. Officials urge cooling measures, hydration, and access to air conditioning or cooling centers as authorities monitor the situation.
Forecasters expect Tropical Storm Bertha to form from a Gulf Coast depression, while a central U.S. heat dome drives dangerous heat (indices up to about 116°F) and a cold front could trigger severe thunderstorms with flash floods from the Midwest to the Mid-Atlantic; wildfire smoke from Canadian fires blankets the Great Lakes region, worsening air quality, and eight flood-related deaths have been reported in Texas, Arizona, and Utah.
A persistent heat dome is pushing western temperatures well above average and expanding toward the Northeast, with about 100 million Americans under heat alerts and several cities forecast to set records. The extreme heat raises wildfire and heat‑related illness risks, while heavy rainfall and flood threats emerge in parts of the South.
A massive heat dome will blanket most of the continental U.S. for about a week, driving temperatures 15–25°F above normal and yielding dangerous overnight heat, with likely multiple new records and elevated wildfire risk; scientists say the event is amplified by climate change.
A widespread heat dome is forecast to push temperatures well into the 100s and up to about 110°F across the Intermountain West and northern Plains, threatening tie-or-break records from Salt Lake City to Billings and driving higher fire-weather risk as drought persists; forecasters warn the heat could intensify this weekend, with monsoonal moisture and a moister air mass potentially offering some relief by mid-to-late July.
A massive upper-level heat dome anchored over Western and Southwestern Europe is trapping hot, dry air and driving temperatures well above normal into mid-July, with Iberia and France already recording 40°C-plus days, tropical nights in major cities, worsening soil moisture deficits, and escalating wildfire risk as the pattern expands north and east toward the UK, Ireland, and central Europe.
A scorching heat wave sweeping the eastern and central United States has killed more than 20 people in the past week, with New Jersey reporting 25 heat-related deaths since July 2. Victims ranged from their 30s to 80s, many found in unair conditioned homes or outdoors. Other incidents include a 74-year-old man in Mississippi and numerous heat illnesses at a Pennsylvania event and in Washington, DC. Officials warn the death toll is preliminary as the East eases slightly with the heat dome shifting, while a new dome may push extreme heat to the West and trigger severe storms through July 7.
A dangerous heatwave is building across the U.S. East Coast, with temperatures around 100F (38C) and heat indices up to 115F for several days over the 4 July weekend, driven by a persistent high-pressure 'heat dome' and drought; the heat threatens outdoor events including President Trump’s Fourth of July celebration and World Cup watch parties, prompting officials to urge people to stay indoors, hydrate, and seek cooling.
Forecasters warn a dangerous heat dome will push the eastern U.S. into record-breaking heat through the Fourth of July weekend, with highs mostly in the mid‑90s to low‑100s and heat indices of 100–115°F in places. Nearly 200 million Americans are under heat advisories as several all-time records are expected to be challenged on the East Coast. The West remains cooler thanks to a persistent trough, while fire danger rises in parts of Utah, Colorado and New Mexico. Stay hydrated, seek air conditioning, limit outdoor exposure, and check on vulnerable neighbors.
