NOAA: Summer 2026 Becomes Hottest on Record Across the Contiguous U.S.

NOAA says meteorological summer (June–August) 2026 was the hottest on record for the contiguous United States, averaging 74.4°F (3.0°F above the 20th‑century average). The heat was broad across the Lower 48, with four states—Colorado, Utah, Arizona, and New Mexico—posting their own summer records, and July’s heat dome driving 100°F+ days and persistently hot nights; the period also saw above‑average minimum temperatures in 17 states and contributed to drought strains in the Colorado River Basin, including record low levels at Lake Powell and Lake Mead.

Heat dome fuels Northeast storms as summer heat lingers into fall

A central U.S. heat dome is driving temperatures above 100°F in much of the South and Midwest, with overnight lows 10–15°F above average. The high-pressure system also steers storms around its edge, bringing rounds of heavy rain and possible flooding to the Northeast and Great Lakes this week. The first heavy rain threat appears Sunday afternoon into Monday, with 2–3 inches possible from the Great Lakes into southern New England, and additional rain rounds likely Tuesday through Thursday with uncertain exact locations. Rising atmospheric moisture from a warming climate is fueling heavier downpours.

Southwest Heat Dome Bears Down, Pushing Temps to Record Lows of Nighttime Relief

A heat dome is driving temperatures to 110–115°F across the U.S. Southwest through late August into early September, with little relief at night and health risks rising for vulnerable groups; monsoonal moisture could bring scattered storms, and cooling centers are opening in some cities as researchers note climate-change linked increases in such extreme heat.

Southeast Braces for Near-Record Heat Dome This Weekend

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.

Western heat wave tightens its grip, threatening record temps for millions

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.

West Suffers in a Heat Dome as Millions Face Record Heat and Fire Threats

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.

California braces for record heat as massive heat dome stalls over the West

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.

Heat dome blankets U.S. as 42 million face heat alerts, temps surge to 119°F

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.

Heat Dome Brings Triple-Digit Heat and Widespread Smoke Across the U.S.

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.

Heat dome blankets central U.S. in dangerous, prolonged heat

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.

Heat, floods, and smoky skies: US faces extreme weather as Bertha brews

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.

Record Heat Dome Targets Drought-Scarred West, Elevating Fire Risk

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.

Heat Dome Grips Western Europe, Prolonging Extreme Heat Through Mid-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.
