From Wikipedia, the free encyclopedia

This is a list of meso-gamma mesoscale discussions, which are issued by the National Oceanic and Atmospheric Administration’s Storm Prediction Center during high-confidence and high-impact severe weather events.[1][2][3][4][5] These can be for tornadoes believed to be at least EF2 on the Enhanced Fujita scale, or winds at least 100 miles per hour (160 km/h). So far, the Storm Prediction Center has issued 43 meso-gamma mesoscale discussions.
