The GFS has blown the thermals at the surface. At this hour they had 35F here. It is 31F now. We have been at freezing or slightly below throughout. The NAM has been the closest on thermals at the surface.
TWC forecasting 3-5" for Boston. I guess they are riding the old GFS, CMC and the Ukie, and giving zero play to the PARA, the NAM, even the 12z and18z Euro, among others like HRRR and RAP. Don't get it.
GFS say 4" here. Para says 18". Which do you believe? Para has been consistent throughout. GFS has been all over the place. Para keeps it below freezing here at h850 and h925, GFS has both freezing lines north of us, with the 925 0° line out to ORH and up to Ray.
