Convective mesoscale discussions are issued by the National Oceanic and Atmospheric Administration’s Storm Prediction Center based on the National Weather Center in Norman, Oklahoma. [ 1 ] [ 2 ] One type of mesoscale discussion is a meso-gamma mesoscale discussion , which are for tornadoes believed to be at least EF2 on the Enhanced Fujita ...
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).
[16] [17] While the violent EF4 tornado was on the ground, Harry Weinman, a forecaster at the SPC, issued a special meso-gamma mesoscale discussion for the tornado. [18] In the discussion, the SPC stated that radar showed debris was being lofted at least 13,000 feet (4,000 m) into the air and that a vertical rotation of 70 knots (81 mph; 130 km ...

Meso-gamma discussion on May 23, 2024, in parts of TX/OK On May 23, the SPC issued an Enhanced risk over central Nebraska to Western Iowa for the threat of damaging winds. Conditions weren't quite as favorable this day compared to others with dew points only expected to reach the upper 50s °F, creating conditions for high-base supercells ...
An extremely critical fire weather event is the greatest threat level issued by the NWS Storm Prediction Center (SPC) for wildfire events in the United States. On the scale from one to three, an extremely critical is a level three; thus, these outlooks are issued only when forecasters at the SPC are confident of extremely dangerous wildfire ...
A meso-beta scale vortex 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 kilometres.
