Arlington and much of the D.C. region will be under a Wind Advisory starting at 10 a.m. Wednesday.
Forecasters say that a line of showers and thunderstorms in the morning will give way to gusty winds through Wednesday evening. The wind gusts may damage trees and cause power outages.
Meltwater from the wet spring snow that fell today may refreeze overnight, leading to treacherous conditions Thursday morning.
That’s the message from VDOT, which issued the following press release this evening.

Four inches of snow has fallen in Arlington, according to the 2 p.m. snowfall total at Reagan National Airport.
The snow has led to slippery roadways and numerous closures. Though above-average temperatures and dogged work by Arlington and VDOT crews has resulted in many main roads being more wet than snow-covered as of mid-afternoon, a number of accidents and spinouts have been reported.

Most roads in Arlington have become snow-covered throughout the course of the morning as the D.C. area’s first — and likely last — big snowstorm of the season continues.
