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.
Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues convective outlooks, mesoscale discussions, and watches as a part of this process. Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3 ...
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 lines, and mesoscale convective complexes .
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 ...
A suprapubic catheter (sometimes called an SPC) is a device that’s inserted into your bladder to drain urine if you can’t urinate on your own.

Talk:List of Storm Prediction Center meso-gamma mesoscale discussions
There are three headlines ordered by severity: "flash flooding likely", "flash flooding possible", or "flash flooding unlikely". [13] Mesoscale discussions (MDs) once were issued by the Storm Prediction Center (SPC) for both convective (MCDs) and precipitation (MPDs) events but WPC now covers this heavy rainfall function.
