Administrators NorthGeorgiaWX Posted December 17, 2023 Administrators Share Posted December 17, 2023 MD 2333 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF THE COASTAL CAROLINAS Mesoscale Discussion 2333 NWS Storm Prediction Center Norman OK 1106 AM CST Sun Dec 17 2023 Areas affected...parts of the coastal Carolinas Concerning...Severe potential...Watch possible Valid 171706Z - 172100Z Probability of Watch Issuance...40 percent SUMMARY...A conditional risk of brief tornadoes or damaging gusts is forecast today, from the South Carolina upper coast toward coastal North Carolina. The risk is conditional on air mass recovery, and a watch may be considered. DISCUSSION...A surface low will deepen as it moves northeastward off the SC Coast today, along an existing baroclinic zone which is currently well offshore. Surface observations show cool air over land with gusty northeast winds, and this will likely maintain a decoupled boundary layer which should mitigate tornado and damaging gust potential in the near term. Later today, gradual warming is expected as the warm front shifts north along the coast. As winds veer to east and then southeast, a warmer and more unstable air mass will then support a risk of brief tornadoes and damaging gusts, as shear will remain strong along the warm front. Observational trends will continue to be monitored closely, along with satellite imagery, to ascertain when a potential watch may be needed later today. ..Jewell/Goss.. 12/17/2023 ...Please see www.spc.noaa.gov for graphic product...
