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.
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).

The Storm Prediction Center issued a mesoscale discussion stating that a tornado with winds of 170–205 mph (274–330 km/h) was likely ongoing, and that it was an 'exceptionally rare event'. The tornado then narrowed to 1.7 miles (2.7 km), but continued to produce EF3 damage as it crossed US 49 to the north-northwest of Seminary. Numerous ...

Mesoscale meteorology. Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall ...
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.
A mesoscale convective system ( MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and ...
