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.
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 ...
Meso-gamma mesoscale discussion See also: List of Storm Prediction Center meso-gamma mesoscale discussions SPC mesoscale discussions for a high-impact and high-confidence strong tornadoes (EF2+) or winds greater than 100 miles per hour (160 km/h) are called meso-gamma mesoscale discussions. Meso-gamma mesoscale discussions are rarely issued by the SPC. As of May 2024 [update], the Storm ...
A mesoscale discussion may refer to: Mesoscale convective discussion, a forecast concerning thunderstorms issued by the Storm Prediction Center (SPC) Mesoscale precipitation discussion, a forecast concerning precipitation issued by the Weather Prediction Center (WPC) Category: Disambiguation pages.
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 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 ...
