Areas affected...New England into southern and eastern Maine

Concerning...Heavy snow=20

Valid 260026Z - 260530Z

SUMMARY...Heavy snowfall rates on the order of 1-2 inches/hour are
expected to linger in portions of New England and gradually spread
north into southern and eastern Maine through the late evening
hours.

DISCUSSION...Latest surface observations and web cams continue to
depict widespread heavy snowfall across the New England region with
visibility reductions down to 1/4 mile or less. This activity
continues to be driven primarily by intense warm air advection
through a deep layer (approximately from the surface through 4 km
AGL based on hodograph curvature in regional VWPs). Latest RAP
mesoanalyses also depict strengthening frontogenesis within the warm
frontal zone, which is enhancing mesoscale ascent across the region.
This frontal zone is expected to gradually shift northward over the
next several hours, resulting in a slow northward spread of
precipitation. Additionally, recent 00z ALB and GYX soundings both
sampled deep saturated profiles with several layers within the
dendritic growth zone. These RAOBs align well with recent forecast
soundings for the greater New England region and will continue to
promote efficient snowfall production. Snowfall rates on the order
of 1-2 inches/hour will likely continue for at least a few more
hours across portions of New England, and an uptick in snowfall
intensity is expected across southern to eastern ME - especially
along the ME coastline where heavy snow banding appears most
probable based on QPF output from recent CAM solutions.
