No watch is expected. DISCUSSION...Thunderstorms have formed along multiple boundaries in a hot and moist environment in the Mid Atlantic. Expect additional storms to develop on these boundaries through the evening. Weak flow (<20 kts) in the lowest 10 km (per LWX VWP) will limit a threat for sustained updrafts. Some strong downdrafts are possible considering the hot conditions and high DCAPE (1200-1300 J/kg) across the region. These pulse type storms may lead to localized strong surface winds where thunderstorm cores collapse, but the lack of any storm organization precludes the need for a severe thunderstorm watch. The corridor with the greatest threat for stronger updraft/downdraft pairs will likely be in northern Virginia/central Maryland where instability is maximized and numerous outflow boundaries are expected to collide within the next 1 to 2 hours. ..Bentley.. 07/21/2019 ...Please see www.spc.noaa.gov for graphic product...
