To hope for a big snowfall this weekend or not?

Service changes are slated to impact 15 out of the 19 operating subway lines this weekend, but because up to six inches of snow is expected to fall by 9 a.m. Friday, the MTA may decide to try to run the trains on a normal schedule.

As of Thursday, the following lines are set to be affected this weekend: 1, 2, 3, 4, 6, 7, A, C, D, E, F, G, N, Q, R.
