As snow showers develop over parts of central Virginia, dry northwest winds are limiting the amount of moisture that can make it as far north as the metro area. Overnight, the metro area will likely be on the northern edge of any snow -- probably resulting in mostly flurries and little accumulation -- especially the farther northwest you go. Further to the southeast, some accumulation is possible per the advisory.

In a recent Special Weather Statement, the National Weather Service did caution that strong winds coupled with remaining ice on trees (in the north and west suburbs) could cause tree branches to fall, with the potential for some more power outages.

It should also be cautioned that:

1) Uncertainty is a bit higher than usual since we're right on the edge of developing snow bands. It could easily not snow at all or snow a bit more than I indicate above in the metro area between now and around 3am.

2) Any snow that does fall could make for slick travel late tonight and early tomorrow morning as temperatures in most areas are already near or below freezing.
