An immense Pacific marine heatwave coinciding with a super El Niño is expected to alter US weather this autumn: California faces higher storm surge and heavy rainfall risks, the Pacific Northwest could see reduced snowfall and drought conditions, wildfire risk rises in the West, Atlantic hurricanes may be suppressed while eastern Pacific storms intensify, and marine ecosystems and fisheries bear the cost of warmer waters.
NOAA data show July was the hottest month on record for the contiguous United States, averaging 3.3F above the 20th‑century average and surpassing all prior July/month records back to 1895. Three heat dome events drove extreme temperatures, with Wyoming recording its hottest July. Widespread wildfire smoke and heat-related disruptions affected daily life, and scientists link the trend to human-caused climate change. An ongoing strong El Niño could push global temperatures to new highs next year, potentially breaking more records as emissions continue.
A dangerous heatwave blankets much of the central and eastern US ahead of the Fourth of July weekend, with temperatures of 95–105°F and humidity driving heat indices to 100–115°F; the National Weather Service warns of widespread, prolonged heat through Friday and into the holiday weekend, NYC records 100°F for the first time since 2012, and officials deploy cooling centers while urging energy conservation as the grid faces strain.
A dangerous heat wave is set to sweep the central and eastern United States this week with 111 million people under heat alerts. Daytime highs are expected in the 90s and 100s, with humidity pushing heat index values to 105–114 degrees. Cities such as Chicago, Kansas City, St. Louis, Nashville, Philadelphia and Boston could feel temps like 100+ degrees by midweek, with New York also approaching 108 and Philadelphia up to 112 later in the week. The heat will persist into the July Fourth period and poses serious health risks, while Europe is facing its own deadly heat wave.
A massive winter storm dumped snow and freezing rain from New Mexico to North Carolina and swept toward the Northeast, threatening blackouts, transportation chaos, and bitter cold as it moved across the US after battering the Southwest and central regions.
A stretched polar vortex is funneling Arctic air into the United States, setting the stage for a significant winter blast with very cold temperatures and potential snow across parts of the Midwest and Northeast as the pattern unfolds.
A triple-dip polar vortex is expected to bring frigid Arctic air to much of the central and eastern US over the coming weeks, causing significant cold surges, snow, and increased energy demands, with temperatures potentially dropping below -25°F in some areas.
A significant Arctic cold front is sweeping across much of the US, bringing snow, record low temperatures, and hazardous travel conditions, with Florida experiencing unseasonably cold wind chills and potential impacts on local wildlife like iguanas.
The northern lights may be visible across 18 US states on Monday due to a geomagnetic storm caused by a coronal mass ejection from the sun, with the best viewing times just after sunset or before sunrise, and the possibility of sightings even outside the direct viewline.
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.
The U.S. Northeast and Midwest are facing severe weather threats including heavy rainfall, flooding, and dangerous heat conditions, with multiple alerts issued across the regions. Climate change is contributing to increased frequency and intensity of such extreme weather events.
This article discusses the recent surge in flash floods across the U.S., driven by climate change-induced increased moisture and storm activity, with over 3,000 warnings issued this year, and highlights the quiet tropical Atlantic with no current storm development expected.
Tens of millions across the US face flash flood risks due to heavy, humid rain fueled by a stalled storm front, with areas from Virginia to the Midwest and Southwest experiencing potential record rainfall and flooding, exacerbated by climate change and recent wildfires.
A large cloud of Saharan dust is expected to reach the southeastern US this week, affecting air quality, visibility, and potentially reducing hurricane activity, while also possibly creating striking sunsets and warmer nights.
About 100 million Americans are under heat advisories as a severe heat wave continues, with temperatures reaching dangerous levels in the Mid-Atlantic states and other parts of the country. New York City and other major cities are experiencing record highs, and the heat index could exceed 100 degrees in several states. The heat wave is exacerbating air pollution and straining public infrastructure, with potential power outages and health risks. This extreme weather is part of a trend of increasingly frequent and intense heat waves due to climate change.
