DISCUSSION...Latest 01Z surface observations show the freezing line draped from northern PA, through southern NY, and into VT/NH. The freezing line has crept south slowly over the past 2 hours in tandem with the synoptic quasi-stationary boundary, and is expected to continue to drag south through Friday morning. However, temperatures ahead of the front have warmed slightly over the past hour, hinting that the southward progression of the freezing line may be slower than depicted by recent guidance. Regional radar mosaics show a broad swath of precipitation moving northeastward into the region, driven primarily by warm advection within a mid-level baroclinic zone. This forcing is forecast to persist over the coming hours, and given the persistent warm nose aloft (as sampled by the 00Z ALB sounding and recently noted in CC data from KBGM), a wintry mix of sleet and freezing rain will continue well into the night. Freezing rain accumulation up to 0.1 inch per hour may be possible for locations that linger in the narrow transition zone. ..Moore.. 02/04/2022 ...Please see www.spc.noaa.gov for graphic product...
