Valid 212043Z - 212215Z The severe weather threat for Severe Thunderstorm Watch 509 continues. SUMMARY...The severe weather threat will continue through the afternoon and into the evening. DISCUSSION...Storms across Virginia and into the DelMarVa have mostly lacked structure thus far with only occasional stronger multi-cell storms. As height falls overspread the area this evening, expect more robust convection with a greater damaging wind threat and an eventual line of storms along or ahead of the cold front, advances east. In addition, strengthening mid-level and low-level flow will assist in storm organization, further supporting the threat. ..Bentley.. 07/21/2026 ...Please see www.spc.noaa.gov for graphic product...
