On March 20, 2025, The Weather Company (TWC) announced it is now the first operational user of the Joint Effort for Data Assimilation Integration (JEDI). JEDI is a groundbreaking weather forecasting framework developed by the Joint Center for Satellite Data Assimilation (JCSDA) and hosted by the University Corporation for Atmospheric Research (UCAR). The Weather Company’s...

As we enter spring and severe weather begins to ramp up, NOAA’s research project Warn-on-Forecast aims to increase the lead time for tornado, severe thunderstorm, and flash flood warnings Traditionally, warnings have been based on detection or indicators of severe weather hazards using Doppler radars, but this “warn-on-detection” approach has reached a plateau. Now, NOAA...

At the end of 2024, AccuWeather closed a deal to acquire TOA Systems, Inc. TOA Systems, Inc. is a premier provider of lightning detection hardware and one of the few global lightning networks in existence. “The integration of AccuWeather’s expertise in machine learning and weather forecasting with TOA’s advanced hardware will dramatically enhance decision-making processes...

With all the recent talks about which federal agencies may see reductions in funding and staff with the new presidential administration, the National Weather Service (NWS) has been at the forefront of conversations. For starters, the NWS costs the average tax-paying American $3-4 per year. That’s about the cost of one cup of coffee. As...

A team of researchers from NASA and their partners are testing new drone technology that could be used for localized forecasting. The team equipped NASA’s Alta X quadcopter with wind sensors, aiming to provide precise and sustainable micrometeorological data to help predict wildfire behavior. With wildfires becoming more common, and wind being a major contributor...

Researchers at the Department of Energy are using the world’s fastest supercomputer to bring up-to-the-minute, pinpoint weather forecasts weeks in advance to the general public’s finger tips. The project is called ORBIT, which stands for Oak Ridge Base Foundation Model for Earth System Predictability. By training the world’s largest AI model for weather prediction, hyperlocal...

As the annual tradition continues, weather-predicting rodents from all across North America emerged from their sleep and offered weather forecasts for either an early spring or six more weeks of winter. There are actually more than 80 weather-forecasting prognosticators, but not all of them record a prediction every year. On February 2, 2025, 43 groundhogs...

As weather apps on mobile devices become more and more popular, the public is quick to make judgments on which apps are and are not accurate. That is of course, in their own opinion, and based on their interpretation of what the app is saying. However, sometimes those interpretations are a misunderstanding of what the...

The need for more accurate global precipitation forecasts is growing as climate change is increasing the amount and intensity of water-related disasters like floods and droughts, as well as for the management of water resources. A research team in Japan has created an algorithm called Local Ensemble Transform Kalman Filter, or LETKF for short. LETKF...

It’s official – La Niña has finally emerged in the tropical Pacific. La Niña is the cool phase of the El Niño/Southern Oscillation, a pattern of sea surface temperature and atmospheric changes in the tropical Pacific Ocean. We’ve been talking about La Niña’s arrival since spring of 2024, and although it took a little longer...
