Discussion              

An unusually cool air mass remains entrenched in the Mid-Atlantic region and an upper-level low spinning overhead will keep it quite unsettled here at mid-week.  With cold air aloft, any daytime heating will quickly result in destabilization of the atmosphere leading to clouds, scattered rain showers and perhaps even a rumble of thunder. The air is cold enough that some can experience small hail or graupel mixed in with the rain later today and tonight. The weather gets quieter and milder at the end of the week and the weekend is shaping up quite nicely.
