NSSL CAPTURES STUNNING DATA ON EF-3 TORNADO
On May 18, 2025 a tornado touched down near the town of Arnett, Oklahoma. Researchers with the NOAA National Severe Storms Laboratory (NSSL) were in place to intercept the storm and capture stunning data of the EF3-rated tornado from beginning to end.
Revolutionizing Hail Forecasts — One Falling Stone at a Time
New high-speed camera captures hail in free fall to improve public safety
Using lightning to monitor the extreme impacts of landfalling hurricanes
A new paper on data collection during Hurricane Ian discusses the deployment of and data collected by a suite of instruments during the landfall of the Category 5 hurricane in Florida in 2022.
The Tornado That Didn’t Surprise: A Story of Preparedness and Partnership
The Warn-on-Forecast System, a revolutionary new forecasting tool being developed by NOAA’s National Severe Storms Laboratory, seeks to equip forecasters with critical information between watches and warnings to allow them to offer longer lead times…
NSSL using tornado tools to study post-wildfire flash floods and debris flows
You likely know the NOAA National Severe Storms Laboratory (NSSL) for its tornado research or radar developments, and its support of the National Weather Service (NWS) mission. However, you may not know the lab has…
Where Have All the EF5 Tornadoes Gone?
The way violent tornadoes in the United States are rated has changed over time, resulting in no EF5-rated tornadoes since 2013, according to researchers from the NOAA National Severe Storms Laboratory in a paper published…
Warn-On-Forecast Hits Milestone: Runs Three Domains at Once
For the first time, the NOAA National Severe Storms Laboratory’s Warn-on-Forecast System (WoFS) has successfully run short-term forecasts for three geographic areas at once—predicting severe weather, winter weather, and fire weather. The historic milestone demonstrates…
A CLEAR VISION: Phased Array Radar innovating for the future
For more than 30 years, the nation’s weather forecasting has relied heavily on the NEXRAD radar network. This network has been the global gold standard in weather radar, however the system is reaching the end of its designed lifespan.
Phased array radar stands as a potential paradigm-shift solution for the future of weather radar in the United States.
SCIENCE IMPACT: Experimental Warn-on-Forecast System yields 75-minute lead time on violent tornado
SCIENCE IMPACT: NSSL’s Warn-on-Forecast System yields 75 lead time on Greenfield, Iowa tornado, demonstrating potential for long-range tornado warnings.
