2025 In a Flash: NSSL Annual Accomplishments Report
Tag: Hot Items
MRMS-Based Tool Enhances Ice Storm Analysis and Forecasting
NSSL has developed an experimental new product that provides a real-time analysis of freezing rain to identify both location and accumulation.
NSSL Advances Tornado Research with Uncrewed Aircraft Systems
Uncrewed Aerial Systems are opening new avenues for researchers to study tornadoes and gather data while staying safe.
SWERVE: Predicting severe weather weeks in advance
The Severe Weather Extended-Range forecasting and Verification Experiment (SWERVE) is testing our ability to forecast severe weather up to three weeks in advance.
RADAR CLUES: New Technique To Help Forecasters Predict Downbursts
NSSL is testing a radar-based technique that spots areas of cold, dense air inside thunderstorms — a key signal for potential downbursts. These bursts of strong, damaging wind can happen fast, especially during summer storms in the Southeast and Southern Plains.
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…
Experimental Phased Array Radar captures wildfire data
For more than 60 years, the NOAA National Severe Storms Laboratory (NSSL) has been at the forefront of developing weather radar. Currently NSSL is working on Phased Array Radar (PAR) as the next generation of…
