Mesoscale Discussion 2125 NWS Storm Prediction Center Norman OK 1133 AM CDT Fri Sep 27 2024 Areas affected...eastern NC and southern VA Concerning...Tornado Watch 688... Valid 271633Z - 271830Z The severe weather threat for Tornado Watch 688 continues. SUMMARY...A few brief tornadoes remain possible through the rest of the afternoon as a weakening band of showers with embedded thunderstorms moves across parts of eastern North Carolina and southern Virginia. DISCUSSION...Despite numerous low-level mesocyclones during the late morning to midday, tornadogenesis has largely appeared elusive within a persistent band of convection from the central NC/VA border area southward into coastal far southern NC. One strong meso with the deepest updraft last hour may have briefly produced in southern NC per an ILM LSR. Low-level winds have subsided across the coastal plain via LTX VWP data, but do remain sufficient for a brief tornado threat amid 74-78 F surface dew points and temperatures in the low 80s. Farther north, low-level hodographs remain rather enlarged, but will shrink throughout the afternoon. Morning CAM guidance suggest a breakup to the convective band should occur, which will yield a more cellular mode. This would favor potential for a few tornadoes, but should be tempered by the otherwise diminishing shear/ascent environment. ..Grams.. 09/27/2024 ...Please see www.spc.noaa.gov for graphic product...
