Haven't had all that much time to look at the models but it seems like it's GFS vs NAM. The GFS model suggests a more southerly track to the low across VA this evening which would give us some snow - mostly from midnight into the early morning hours tomorrow. An inch to slightly more is probably all we can look for from this.
The NAM is even worse. A more northerly track almost over us decreases the amount of moisture available, introduces the dry slot and makes atmospheric temperatures questionable with regards to the rain/snow line.
Based on the morning model runs, I'd say around an inch or two - but I'll take a look at the afternoon models as well.
Either way - shouldn't be a big deal and I don't expect it will start until closer to midnight tonight - maybe even later.
