There's always a possibility. You need to understand that the schools sometimes close in D.C. when there's under 2" of snow, and we're at the mercy of the school authorities who have total control over whether their facilities are open. This part of the world does not deal well with winter. Right now, they're predicting the infamous "mixed precipitation" (ice, sleet, snow) for Sunday, but so far the forecast for Saturday is for fair skies, temps in the low 30s.
