 Mesoscale Discussion 0793 NWS Storm Prediction Center Norman OK 0512 PM CDT Mon May 16 2022 Areas affected...Central and Eastern North Carolina Concerning...Severe Thunderstorm Watch 228... Valid 162212Z - 162315Z The severe weather threat for Severe Thunderstorm Watch 228 continues. SUMMARY...The severe weather threat will continue for a few more hours. DISCUSSION...A few supercells and multicell clusters continue within watch 228. The strongest storms are in eastern portions of the watch where the greatest instability is present. Farther west, the airmass ahead of these storms has cooled as an outflow boundary has surged ahead. Therefore, enough instability exists in a moderate shear environment (30-35 knots) to support some severe weather threat, but the greater threat remains farther east. The severe weather threat remains more questionable in southern portions of watch 228. A few weak storms have developed in northern South Carolina, but have remained sub-severe thus far. This airmass has not been impacted by earlier convection, but dewpoints have mixed into the low 60s. Therefore, some strong to severe storms are possible, especially near the sea breeze boundary where greater low-level moisture is present, but the lesser instability may also preclude more robust thunderstorm development. ..Bentley.. 05/16/2022 ...Please see www.spc.noaa.gov for graphic product...
