The National Oceanic and Atmospheric Administration National Weather Service Storm Prediction Center published an updated set of online products that highlight ongoing severe weather resources and recent research. The SPC web pages list watch summaries, outlooks, probabilistic forecasts, and multiple climatology tools for public and professional use.
The site shows Tornado Watch and Severe Thunderstorm Watch summaries with both pages last modified September 11 2026 at 12 28 UTC. The home page also lists daily severe probabilities for September 12 and links for tornado, damaging wind, and severe hail probabilities for the same date.
The SPC site includes climatology archives, with severe weather climatology covering 1994 to 2024 and wildfire climatology covering 1992 to 2020. The page offers multiple wildfire probability products for specific acreage thresholds and directs readers to more climatology data on the site.
The SPC case archive entry for September 09 2026 records zero reported tornadoes, 59 wind events, and one hail event. The center also promotes tools and partnerships on the site, including the Tornado Environment Browser and a partnership labeled #TornadoStrong with FLASH Forecast Tools. A Spanish language blurb reads La tormenta factor de riesgo.
Research Highlights And Operational Links
The SPC publication list on the site shows recent peer reviewed papers that address several operational and scientific topics. In 2026 Squitieri Wade and Jirak published a study on a comprehensive archive for derechos in the Bulletin of the American Meteorological Society. Earlier work by the same authors proposed a modified definition of a derecho and offered an updated spatial climatology in 2025.
Other highlighted research includes a 2026 Weather and Forecasting paper by Chalmers and Parker on variability in high shear low CAPE quasi linear convective system environments in the Southeast. Lyons and colleagues contributed a 2026 Weather and Forecasting study on convective mode classification and tornado distribution from 2003 to 2023.
The list also contains two 2025 papers by Harrison McGovern Karstens Bostrom Jirak and Marsh that examine coproduction and expert evaluation of machine learning in operational meteorology, both published in Weather and Forecasting. A 2024 study by Moore on near surface wind fields of downbursts is also shown.
The SPC page invites users to find more research in its publication archive and to use operational tools made available online. These combined resources link recent scientific findings to the center's watch summaries and probabilistic forecasts as presented on the SPC website.
