Those of us very far south, points from where I am at in Charleston on down, "winter" is for all intents and purposes about over. The sun angle and length of day is rapidly increasing. For VA, I would agree, still lots of time to go as you are much farther north and more prone to the mid-latitude storm systems.
We can see a few cold nights and get around 32 (at 6-7am just before sunrise or for a few hours at best) a few more times here on the Charleston coast but that window is closing with every passing day. After this week, GFS 2m temps are showing 67-70 each day and lows in 50s at night for several days.
About time to get the pre-emergent down in the yard.
