The Snow Lover's Crystal Ball has been murky the last couple of days concerning the possible snowstorm this weekend. The threat seemed to be waning yesterday as computer models seemed to be approaching a no-storm consensus except for several pesky ensemble members (subsets of these models with slightly varied data inputs) that kept screaming "not so fast."

This morning's model runs trended back toward a storm suggesting that there is more potential than I may have thought when writing yesterday's post. And so, the CWG has dusted off the old crystal ball which still is a little foggy but providing glimpses of a potential snowstorm that might be bigger than today's if everything comes together perfectly.

Probability of accumulating snow (1" or more): 30%

Maximum accumulation potential: 6"+

U.S. government offices are open Friday.

Some school systems have announced delays or closures.

7:15 p.m. update: The storm is over.

5:15 p.m.
