Sterling, VA Initial Environment

Overall, a large area of high pressure dominates the central United States with a surface cold front draped across the Appalachian Mountains through Pennsylvania, West Virginia and eastern Kentucky and Tennessee. A small trough was also centered over Virginia  and North Carolina. A decent cu field accompanied the cold front with GOES CI values mostly 30% or less as of 1830Z.

All the CAPE was concentrated over eastern North Carolina, with values of 500 J/kg or less over Maryland and eastern Virginia. A fairly steep PW gradient cut through central Maryland with .75-1 inch in the northeast part of the state, up to just over 1.5 inches in the southeast portion.

Any storms that do form over the CWA will be in the next few hours as the cold front moves through , but likely not severe.
