I have been in DC for a number of these 2'+ snow falls and it tends to
jam the place up for quite a while. A lot depends on what comes behind
it. Sometimes it warms up and things actually get worse because it
still freezes over night so you get black ice. My Firebird wore a
little reminder of that until after I sold it.
If it snows again it even gets uglier and people just stay home for
days.
I got propane, so I can bbq. Whenever I see a Dominion Virginia Power truck in the
neighborhood I go thank the guy. We've not had an outage over a few hours since I
moved here in 1995 (knock on wood).
Power outages were really pretty rare in the olden days. I don't
remember them at all when we lived inside the DC line and very rare
just over the line in PG. When I moved down to Clinton in the 70s we
had a few that lasted more than an hour but not many. Now my Ex says
it happens often enough that she bought a generator.
Ice storms were worse than the snow. (The old "sleet and freezing
rain" that was worse than a good snow)
This storm looks unusual because all the snow will come at once. Our
big snow events usually involved it snowing every day or two for a
week or so. Worst case was a pattern of cold air from the west and a
low coming up from the south. That was when PG got slammed. It usually
snowed a lot more in Montgomery and Frederick.
