Computer model average snowfall forecast for Saturday. (00z Euro, 9z SREF, 12z NAM/GFS)

The computer models are predicting a period of light to moderate snow on Saturday. The graphic above takes the various computer model forecasts and creates an average forecast, based solely off of those models. 

11:15 a.m. update:
This data includes 00z Euro, 9z SREF, 12z NAM/GFS. 

My thoughts:
Most of the guidance indicates anywhere from 1 to 4 inches of snow, but the GFS has been throwing out some much higher numbers. In fact, the latest GFS run (12z) was showing 3 to 9 inches across the state.

The forecast does bear watching. A series of disturbances are expected to pass through the area between Friday and Sunday. The one on Friday should stay to our northwest, but the one on Saturday could bring at least some snow to the area. The system on Sunday is the big coastal storm that is still expected to stay well east of New England.

Stay tuned to for the latest weather discussions.
