A watch is not anticipated. DISCUSSION...Clusters of storms are ongoing across the eastern West Virginia Panhandle and northern and eastern Virginia. Per ACARS profiles from BWI and DCA, the atmosphere is very moist with poor mid-level lapse rates. Additionally, regional VWPs indicate shear is fairly weak (25 kts of 0-6 km bulk shear), though this may be enough for some loosely organized multicell convection. Given the thermodynamic environment, water loading in downdrafts may cause some damaging gusts, particularly where storms have clustered and precipitation mass is concentrated. There is a general northwest-southeast gradient in CAPE in the region, though poor low-level flow across this gradient suggests that convection will be difficult to sustain with the loss of daytime heating. Because of this and the expected sparse coverage of damaging gusts, a watch is not anticipated. ..Supinie/Smith.. 06/15/2025 ...Please see www.spc.noaa.gov for graphic product...
