The arrival of El Niño is increasing confidence in a quieter-than-normal 2026 Atlantic hurricane season. Colorado State University now expects only 11 named storms this year, well below average. Still, forecasters warn that it only takes one landfalling hurricane to cause significant impacts, regardless of seasonal totals.

The maximum heat index, or feels-like temperature, is forecast to reach 109 on Friday, 106 on Saturday and 105 on Sunday, according to the National Weather Service.

When the usual explanation failed, the weakening Madden–Julian Oscillation emerged as the main reason for the decline in tropical cyclones over recent decades.

Scientific Data, Published online: 12 June 2026; doi:10.1038/s41597-026-07519-2 A global dataset of land-atmosphere coupling metrics based on observations for evaluating Earth system models

Sentinel-6 satellite data shows strengthening warm-water waves in the Pacific, pointing to the likely arrival of El Niño and its global weather impacts later in 2026. Several months before an El Niño develops, large waves of warmer, elevated water travel eastward across the Pacific Ocean. Satellite observations in 2026 have detected several of these waves. [...]

Three key challenges hinder the identification of short-term heavy precipitation (STHP) over the Yangtze River Delta region: feature selection, sample imbalance, and poor physical performance of models. To address these issues, this study developed a physically consistent cascade recognition model based on ERA5 reanalysis data from 2020 to 2024 and high-density ground-based observations. The mode…

With matches in 16 cities across the US, Mexico and Canada, players and fans face an array of weather-related challenges With the 2026 World Cup now under way, all 48 teams face a common opposition: summer weather across North America. Matches will be played in 16 cities, from southern Mexico to Canada, with a range of weather risks possible at each venue. Thunderstorms disrupted play before the …

A dozen students participating in NASA’s 2026 Student Airborne Research Program collected data about the atmosphere, using a weather balloon that measures ozone concentrations as it rises. The post Up, Up, and Away With Weather Balloons appeared first on NASA Science .

Cold fronts colliding with warm, humid air from the Gulf of Mexico could cause dangerous weather conditions, forecasters say

Abstracts are now being accepted for the session, which will take place at the 2027 AMS Annual Meeting. The post NASA, NOAA to Hold Joint Session at 23rd Symposium on Operational Environmental Satellite Systems appeared first on NASA Science .

A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle sizes.

In July 2021, a rare and extremely severe rainstorm and flood disaster occurred in Henan Province, China. Using multiple daily observational and reanalysis data, this study investigates the modulation mechanisms of the boreal summer intraseasonal oscillation (BSISO) on the Henan extreme rainfall event. The analysis is conducted within the framework of the dual-mode BSISO indices (BSISO1: 30–60-da…

A recent preprint (not yet peer-reviewed) reports that when global average lower-troposphere temperature (TLT) is adjusted to remove the influence of ENSO (el Niño Southern Oscillation) and of aerosols, the resulting adjusted data reveal unambiguous...

This is a re-post from Yale Climate Connections by Bob Henson It might have seemed exotic when it first appeared, but the forecast “cone of uncertainty” used by the NOAA/NWS National Hurricane Center (NHC) is now a familiar part of tropical cyclone readiness in U.S. states and territories. For 2026, NHC has made a couple of key tweaks to its standard cone product. It’s also testing an expanded ve…

Tropical Storm Boris has formed and is expected to bring heavy rain to parts of southern Mexico's Pacific coast

Meteor storms may pose a hidden danger to NASA’s Artemis lunar missions, challenging spacecraft safety and mission timing.

Aircraft icing poses a catastrophic threat to aviation safety. This study conducts a comparative investigation of two typical severe icing events, occurring in summer (July 2023) and winter (January 2024) over the Sichuan-Chongqing region, using pilot reports, ERA5 reanalysis data, geostationary satellite observations (Himawari-9/FY-4A), radar products, and sounding data. The research aims to dis…

India declares onset as up to 280mm of rain falls in 72 hours in Kerala, while downpours hit south-west Thailand The monsoon season has officially begun in parts of Asia, marking the start of a period of enhanced rainfall vital to the region’s economy. The south-west monsoon begins each year as a consequence of a growing temperature difference between the Asian land mass and the Indian Ocean. Thr…
