Overall, the GFS did not do a good job predicting precipitation. This model run is forecast hour 54 and over predicted precipitation. The area over the east coast has no precipitation according to the radar, however the GFS predicted precipitation probably due to the mountains and off the Great Lakes.

This image compares recorded surface observations to forecast surface freezing line. Overall the GFS did a very job predicting as then was the 72 hour forecast. Nearly all the points north of the line are below freezing while all of the points south are above freezing.
