Saving Lives & Property…

NOAA’s National Severe Storms Laboratory serves the nation by working to improve the lead time and accuracy of severe weather warnings and forecasts in order to save lives and reduce property damage. NSSL scientists are committed to their mission to understand the causes of severe weather and explore new ways to use weather information to assist National Weather Service forecasters and federal, university and private sector partners.

At NSSL, our basic and applied research focuses on understanding severe weather processes, developing weather observation technology, and improving forecast tools, with emphasis on:

Warn-On-Forecast Hits Milestone: Runs Three Domains at Once

March 13, 2025

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

November 14, 2024

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.

Threats in Motion

In nature, hazardous weather is almost always in motion. New research and technology are making it possible to provide more continuous information about the storm and its movement. Threats in Motion (TiM) is the next step in the evolution of how weather information is provided to the public. Learn more →

Advanced Technology Demonstrator

Radar research at the NOAA National Severe Storms Laboratory has taken another step forward. The Advanced Technology Demonstrator is the first full-scale, S-band, dual-polarization phased array radar built from the ground up and designed specifically for use as a weather radar. Learn more →
