MD 0677 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR EASTERN NORTH CAROLINA INTO FAR SOUTHEAST VIRGINIA


Mesoscale Discussion 0677

0547 AM CDT Sun May 04 2025

Areas affected...eastern North Carolina into far southeast Virginia

Concerning...Severe potential...Watch unlikely 

Valid 041047Z - 041345Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated strong gusts, and perhaps a brief/weak tornado,
cannot be ruled out over eastern North Carolina and eventually into
far southeast Virginia.

DISCUSSION...A line of convection with wind shift continues to push
east, now completely out of SC and over eastern NC. Earlier, a 50 kt
gust was measured near North Myrtle Beach. 

In addition to the narrow north-south line of convection, other
storms have developed ahead of the line. These storms have shown
periodic weak mesocyclones. Other storms continue to show
near-severe inbound velocities mainly over the water, but this
activity may eventually move inland.

The air mass is marginally unstable, but sufficient for isolated
severe reports this morning. Low-level SRH with 0-1 km values of
100-150 m2/s2 will continue to favor rotation within the stronger
storms, though any tornado risk should remain low-end in nature.
