A rapid analysis by World Weather Attribution finds the West heatwave this week is largely driven by the climate crisis, showing the event would be about four times more likely in a warming world and temperatures up to 30°F above March norms from California to Colorado, with health, infrastructure, and economic impacts and a warning that such extremes will become more common without policy changes.
A massive high-pressure heat dome is trapping hot air over the U.S., expanding into the East and producing a sweeping, potentially historic March heat wave with many states recording or nearing new March highs; temperatures in the 90s are expected across the southern and central Plains, and several locations hit 112°F in the Southwest. The heat is expected to persist into mid-next week as the dome shifts east, while scientists say climate-change warming has made such extreme heat far more likely.
A West Coast heat dome likely produced the hottest March temperatures in US history, with Martinez Lake, AZ hitting 110F and Indio and Thermal, CA reaching 108F; nationwide March records were preliminarily tied, highlighting how climate change is boosting extreme heat and expanding heat waves across the region.
An early-week heat wave overwhelmed the West, with about 38 million people under heat alerts as temperatures surged into the 90s and 100s and numerous March records were set from California to Arizona (e.g., Palm Springs 107°F, Indio 108°F, Phoenix’s earliest 100°F day). Boise also logged an 80°F winter high, and Las Vegas reached a March-record 95°F. The heat is forecast to move east into the Rockies and Plains, raising wildfire risks in Colorado and surrounding states.
A historic March heat wave is unfolding across the Western U.S., fueled by a powerful heat dome and human-caused climate change. Forecasters warn temperatures could break multiple records from California to Montana, with Phoenix possibly reaching 106°F, creating serious health risks as residents cope with heat before cooling access is widespread. The extreme warmth could accelerate snowpack melt, threaten water supplies, and elevate wildfire risk, echoing and potentially rivaling the 2021 Pacific Northwest heat dome in intensity and consequences.
A four-front weather week grips the U.S.: a western heat dome brings near-record warmth and fire weather, an East Arctic blast dumps heavy snow and plunges temps, a Great Lakes cyclone adds blizzard conditions, and severe East Coast thunderstorms risk damaging winds and tornadoes as the jet stream buckles.
An anomalously early heat wave is boiling the western U.S., with Southern California highs reaching the 90s and parts of Arizona and Nevada in the triple digits as about 39 million people are under heat alerts. The National Weather Service says a high-pressure heat dome will drive daily record highs and likely extend through the week, raising concerns about heat risks, drought, wildfire potential, and water supply. The West is also contending with reduced snowpack, while a separate winter storm hits the Midwest and Hawaii endures heavy rains from an atmospheric river.
Forecasters warn of a rare, multi-system weather assault across the U.S.: a Southwest heat dome could push triple‑digit heat, a polar-vortex chill will dip temperatures into the Midwest and East, two back‑to‑back snowstorms including a potential bomb cyclone may slam the northern tier and Great Lakes, and Hawaii faces heavy rain from an atmospheric river while the jet stream—linked to Arctic warming—drives extreme swings. Some areas could see record highs while others endure record lows as spring approaches.
An intense heat dome and high humidity in the eastern U.S. are causing dangerous wet-bulb temperatures, nearing levels that threaten human survival, with climate change likely to make such conditions more common and severe in the future.
Nearly half of the U.S. population is under heat alerts due to a heat dome causing extreme temperatures across many major cities, including Orlando, New Orleans, and St. Louis, with others under lower-tier advisories.
A severe heat dome is causing dangerous heat conditions for over 100 million people across the US, with high temperatures, humidity, and risk of heat-related illnesses, especially in the southeast and Tennessee Valley, while thunderstorms and wildfires also pose additional hazards.
A heat dome combined with the 'corn sweat' phenomenon is causing a dangerous heat wave across much of the eastern U.S., with high humidity and temperatures over 105°F in some areas, exacerbated by climate change, posing serious health risks and emphasizing the need for safety precautions.
A heat dome is expected to bring a significant heat wave to Michigan midweek, with temperatures rising into the 90s and potentially reaching 100 degrees by Thursday, accompanied by increased humidity and heat index values, with some relief possible by Friday due to thunderstorms.
Europe is experiencing an unprecedented heat wave with record temperatures in Spain, Portugal, Germany, and France, driven by a persistent heat dome. The UN Secretary-General warns that extreme heat has become the new normal, as authorities issue red alerts and deal with heat-related emergencies, including wildfires and health risks. The heat is also affecting events like Wimbledon, with the hottest opening day on record.
A heat dome, caused by a high-pressure system trapping warm air, is causing extreme temperatures across the eastern U.S., with warnings for health risks and record-breaking heat linked to climate change. The phenomenon acts like a lid on a pot, leading to prolonged heat and dry conditions, and is influenced by jet stream patterns. Similar events have occurred across the U.S. in recent years, with increasing severity due to global warming.
