East Coast Chasing
Chasing is possible in some areas of the east, but several factors make it very difficult: a) roads....lot's-o-curves, forested, etc. B) visibility....trees, terrain, low cloud bases c) storms....occasionally we get a long-lived classic supercell, but more often it seems we deal with HP's, mini-supercells, and storms embedded in squall lines, etc. Many times we seem to have rotating storms develop in a modestly unstable (CAPE of maybe 1000) but highly sheared environment, producing low-topped convection that does produce tornadoes.
Every year there are storms worth chasing in VA/NC, but many times the lead time doesn't allow me to reach anything (i.e. leaving work early and have a 4-year old at home). Tropical season brings on its own challenges, brief spin-ups with fast-moving storms in a limited-visibility environment (LOTS of rain).
Since some of the convective variables tend to not be quite as strong as what you'd typically find in the plains, it seems severe weather is more sporadic, and tough to forecast a target area more than a few hours ahead of time. Lot's of times it's "hey storms are firing, can we get there???".
Here in VA/NC region, there seems to be a number of "hotspots" east of the Appalachians, and in our local CWA the area along the VA/NC border seems to get its fair share of activity (Pittsylvania VA to Rockingham NC on eastward). The following pict/link is from the Blacksburg VA NWS office, and it shows an F3 tornado moving into VA from Rockingham County NC. This was a long-track event, and probably a one in 10 or 20 year event for our local area.

I am not familiar with the scene in Northern Virginia, but they seem to get a fair number of severe/tornadic storms up there (maybe due to population density that they get reported more???). Depending on location, traffic may be an issue there. If you were lucky enough to find yourself intercepting a nice supercell in VA...you'd think you were chasing 15 years ago...because you'd be the only one on the storm!
