The Storm Prediction Center ( SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), [1] which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC).

A high risk severe weather event is the greatest threat level issued by the Storm Prediction Center (SPC) for convective weather events in the United States. On the scale from one to five, a high risk is a level five; thus, high risks are issued only when forecasters at the SPC are confident of a major severe weather outbreak.
Part of the Tornadoes of 2024. From April 25–28, 2024, two separate large and destructive tornado outbreaks occurred back-to-back across the Midwestern, Southern, and High Plains regions of the United States, primarily on April 26 and 27. [2] On April 26, a tornado in Lancaster County, Nebraska, injured three people, [3] which touched down in ...
Meteorological synopsis High risk convective outlook issued by the Storm Prediction center at 13:00 UTC on May 6 May 6. Starting April 30, the Storm Prediction Center noted that certain models, including the ECMWF, forecasted a multi-day period of high instability and supportive wind shear across the Southern and Central Plains, and by May 1, a 15% risk was added across Nebraska, Kansas ...
Also in April, Timothy A. Coleman, with the University of Alabama in Huntsville (UAH), Richard L. Thompson with the NOAA Storm Prediction Center, and Dr. Gregory S. Forbes, a retired meteorologist from The Weather Channel publish an article to the Journal of Applied Meteorology and Climatology stating, "it is apparent that the perceived shift ...
Severe. F4. 207–260 mph. Devastating. F5. 261–318 mph. Incredible. The Fujita scale ( F-Scale; / fuˈdʒiːtə / ), or Fujita–Pearson scale ( FPP scale ), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.
The Storm Prediction Center issues daily outlooks denoting the risk for severe weather and wildfires for specific regions in the United States. For severe weather, which includes the risk for thunderstorms, tornadoes, hail, and straight-line winds, there are five risk levels indicating the probability for these hazards: marginal, slight, enhanced, moderate, and high.
