Low pressure tracked eastward across southern portions of the Ohio Valley during the day on March 18th while a warm front that started the day over northern South Carolina moved northward toward the local area. This warm front would serve as the focal point for much of the severe weather observed across Virginia as well as North Carolina during the late afternoon through evening on the 18th. By around 4-5 PM, the warm front made it to a Greensboro (NC)-South Hill-Wakefield-Williamsburg line before stalling. A strong cold front remained well to our north through the evening. A line of (initially) elevated convection formed across western NC during the early afternoon. This line moved eastward into the North Carolina Piedmont and one of the cells produced a tornado near High Point, NC (just SW of Greensboro). Meanwhile, a cluster of hail producing rotating cells formed across south-central/interior portions of SE Virginia (in the Wakefield CWA) by 5 PM. While these prompted both Tornado and Severe Thunderstorm Warnings from Emporia, VA to Hampton Roads, only severe hail (up to half dollar size) and a little but of straight line wind damage was observed. 

However, the aforementioned line of convection entered western portions of the Wakefield CWA by around 7:30 PM. Initially, the convection was all elevated given that the warm front had not moved to the NW of Greensville/Brunswick Counties. That line of convection traversed the Wakefield CWA during the next few hours. The southernmost cell in the line roughly followed the warm front, and it produced 1 tornado in Walters, VA (in far southern Isle of Wight County) and one area of 65-85 mph straight line winds in Northampton County, NC. This was likely due to the enhanced low-level directional shear (and thus Effective SRH) near and just south of the warm front. See "Environment" section for images. Additionally the tornado in the Wakefield CWA (and the one in High Point, NC) occurred near the greatest temperature/instability gradient (associated with the warm front). While environmental parameters seemed favorable for severe weather (and tornadoes) to our SE, no severe weather occurred deep in the warm sector across eastern and SE North Carolina. This was likely due to a lack of forcing in the warm sector. Quite a few of our past severe weather cases feature reports clustered along an instability gradient/front.
