NOAA Predicts Warmer Fall with Wetter Conditions in Southwest and Southeast

NOAA Predicts Warmer Fall with Wetter Conditions in Southwest and Southeast

The National Oceanic and Atmospheric Administration (NOAA) has released its fall 2026 forecast, predicting warmer-than-average temperatures across most of the United States from September through November. The strongest warming signals are expected in the Pacific Northwest and northern Rockies, with above-average temperatures also likely in the West, Great Plains, Gulf Coast, Northeast, and Mid-Atlantic regions. Meanwhile, wetter-than-normal conditions are forecast for the Southwest, including Arizona and New Mexico, as well as parts of the Southeast, such as Georgia and the Carolinas. Conversely, drier-than-normal conditions are anticipated in the Pacific Northwest and areas around the Great Lakes. This forecast coincides with a strengthening El Niño event in the tropical Pacific, which has a greater than 90% chance of becoming a very strong event during the fall and winter months (NOAA, 2026).

Super El Niño to Peak in January, Impacting U.S. Winter Weather Patterns

Super El Niño to Peak in January, Impacting U.S. Winter Weather Patterns

The 2026-2027 winter season is set to be heavily influenced by a Super El Niño, with January expected to be the peak period for its atmospheric effects. According to multiple forecasts, including those from NOAA, ECMWF, and UKMO, the El Niño will drive an active southern storm track, bringing above-average snowfall to regions like California's Sierra Nevada, Utah's Wasatch canyons, and the southern Rockies. Meanwhile, the Polar Vortex is forecast to weaken in late December and January, potentially allowing cold Arctic air to spill into the central and eastern United States. This combination of factors is expected to create a dynamic winter weather pattern, with significant snowfall in some areas and warmer, drier conditions in others. The Farmers' Almanac has dubbed the season one of "Snow, Sleet, and Surprises," highlighting the potential for sudden cold bursts and variable conditions across the country.

El Niño Expected to Bring Milder Winter to Chicago, NOAA Reports

El Niño Expected to Bring Milder Winter to Chicago, NOAA Reports

The National Oceanic and Atmospheric Administration (NOAA) has forecasted a milder-than-usual winter for Chicago due to a 'very strong' El Niño event, which has a greater than 90% chance of persisting through fall and winter 2026. El Niño, a climate phenomenon caused by warmer-than-average Pacific Ocean surface temperatures, is expected to shift the Pacific jet stream southward, leading to warmer and drier conditions across the northern United States. For the meteorological winter (December through February), Chicago has a 40% to 50% chance of experiencing above-normal temperatures, with the city's average winter temperature typically around 28°F (-2°C). However, experts caution that this does not eliminate the possibility of snow or severe winter storms. Source time: 2026-09-02 18:42:58 GMT.

Central U.S. Heat Dome Set to Fuel a Weekend Swelter

Central U.S. Heat Dome Set to Fuel a Weekend Swelter

A massive heat dome will dominate the central and southern Plains and Mississippi Valley during the Labor Day weekend, Sept. 5–7, bringing widespread highs in the 90s to low 100s, with temperatures up to 15 degrees above average. Meanwhile, showers and thunderstorms will surround the heat dome across the West, northern Plains, Midwest and Southeast. Some storms could produce torrential rain, flash flooding and gusty winds. The Northeast will be cooler, while tropical activity near Florida will also be monitored. Travelers should expect heavier traffic and possible flight disruptions.

El Niño Intensifies: UN Warns of 'Supersized' Weather Impacts

El Niño Intensifies: UN Warns of 'Supersized' Weather Impacts

The United Nations has issued a warning about an intensifying El Niño event, described as 'supersized,' with a nearly 100% likelihood of persisting until February 2027 (Yahoo News, 2026). This natural climate phenomenon, characterized by warming sea surface temperatures in the Pacific Ocean, is expected to significantly alter global weather patterns. In the U.S., El Niño typically brings wetter conditions to the South, milder temperatures to the North, and a quieter Atlantic hurricane season. NOAA predicts this El Niño could become the strongest in 70 years, with sea surface temperatures in the Niño 3.4 region already 2.2°C to 2.6°C above average (WMO, 2026). The event is expected to peak by late 2026, with impacts likely to extend into 2027.

Strong El Niño Forecast Raises Questions for Delaware's Winter Weather

Strong El Niño Forecast Raises Questions for Delaware's Winter Weather

A strong El Niño event is currently underway, with the National Oceanic and Atmospheric Administration (NOAA) reporting its commencement on June 11. Forecasters predict a 90% chance of a very strong El Niño this winter, meaning equatorial Pacific surface temperatures are 2 degrees Celsius warmer than average. Some scientists suggest this El Niño could reach historic levels. While El Niño has global impacts, its effects on Delaware are expected to be less pronounced compared to other U.S. regions. Sarah Johnson, a coordinating meteorologist for the National Weather Service in Mount Holly, New Jersey, noted that Delaware's winter weather is more influenced by the North Atlantic Oscillation than El Niño. However, a significant impact for Delaware is the suppression of tropical activity, with a 75% chance of a below-normal number of tropical storms. Historically, very strong El Niño events have shown varied impacts on Delaware, with past events in 2015-16 and 1997-98 resulting in different snow totals despite ...

Extreme Heat and Flash Flood Risks Across Central and Southern U.S. During Labor Day Weekend

Extreme Heat and Flash Flood Risks Across Central and Southern U.S. During Labor Day Weekend

A massive heat dome is expected to bring extreme temperatures to parts of the central and southern Plains, as well as the Mississippi Valley, during the Labor Day weekend. According to AccuWeather, temperatures in cities across Texas, Oklahoma, Missouri, Tennessee, and Nebraska could exceed 100°F (37.8°C), with high humidity making it feel up to 15°F (8.3°C) hotter. Meanwhile, showers and thunderstorms are forecast around the perimeter of the heat dome, affecting regions in the West, Midwest, northern Plains, and Southeast. The National Weather Service (NWS) has issued heat advisories for large portions of the Mississippi, Ohio, and Tennessee Valleys. Additionally, flash flooding risks are heightened in Texas due to heavy rainfall from Tropical Storm Edouard, which has weakened to a tropical depression.

Strengthening El Niño Expected to Suppress Atlantic Hurricane Activity

Strengthening El Niño Expected to Suppress Atlantic Hurricane Activity

Forecasters are predicting a quieter Atlantic hurricane season this year due to the strengthening of El Niño, a natural climate pattern characterized by warm surface water temperatures in the Pacific Ocean. According to the National Oceanic and Atmospheric Administration (NOAA), there is a 90% chance that El Niño will reach a 'very strong' status during the peak of the hurricane season, which runs from June 1 to November 30. Historically, such strong El Niño events are rare, with only six recorded since 1950. This phenomenon tends to suppress storm development in the Atlantic while increasing tropical storm activity in the Pacific. So far, five named storms have been recorded in the Atlantic, which is below the average of 14 for the season.

NOAA Adopts New Metric to Measure El Niño Strength in Warming Climate

NOAA Adopts New Metric to Measure El Niño Strength in Warming Climate

The National Oceanic and Atmospheric Administration (NOAA) has adopted a new metric, the Relative Niño-3.4 Index, to more accurately measure the strength of El Niño and La Niña events in a warming climate. This change addresses a growing challenge where traditional measurements, which compare sea surface temperatures in the tropical Pacific to a long-term average, were becoming less reliable. In recent years, warming trends across the tropical oceans have complicated the relationship between central tropical Pacific surface temperatures and atmospheric responses. For instance, strong El Niño-like sea surface temperatures (Niño-3.4 index values) were observed with weaker atmospheric responses, as seen in 2023–24. Conversely, relatively weak La Niña events (cooler-than-average sea surface temperatures) in 2024–25 exhibited stronger atmospheric changes than expected. The new Relative Niño-3.4 Index compares the surface temperature anomaly in the Niño-3.4 region to the average anomaly across the entire tropica...
