THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE COASTAL CAROLINAS
### SUMMARY
A few strong to severe thunderstorms posing a risk for gusty winds and perhaps a tornado could occur across parts of coastal North Carolina this evening/tonight.
Coastal Carolinas
Within an amplifying upper flow regime over the CONUS, an upper trough over the Midwest/Upper Great Lakes will progress east-southeastward toward the central Appalachians and Mid-Atlantic/Carolinas through tonight. In response, steady surface cyclogenesis (9-10mb/12hr) is expected tonight along the coastal Carolinas, with some potential inland advancement of the offshore warm/moist sector where middle 60s F surface dewpoints exist in proximity to the Gulf Stream.
Scenario-typical short-term model characteristics and biases are experientially apparent in latest available guidance, with recent NAM runs most optimistic for near-coastal/just-inland cyclogenesis and destabilization, potentially too much so as compared to more offshore GFS/ECMWF guidance given the expected increasingly prevalent precipitation inland tonight. Regardless, some near-coastal potential will exist tonight for a couple of supercells/severe-caliber severe storms potentially capable of wind damage and/or a tornado, with the North Carolina Outer Banks having the primary vulnerability late this evening into the overnight.
