Areas affected...northern VT and NH into portions of western and
central ME

Concerning...Heavy snow 

Valid 021304Z - 021700Z

SUMMARY...Heavy snow will shift eastward from northern VT/NH into
parts of western/central ME this morning. Snowfall rates around 1
inch per hour are expected, with some areas briefly seeing rates as
high as 2 inches per hour.

DISCUSSION...Areas of heavy snow are ongoing across parts of
northern VT and NH as a band of 700 mb frontogenesis strengthens
ahead of the midlevel trough/low. Strong forcing and a warm/moist
advection around 850-700 mb is aiding in a deep, saturated layer
extending vertically through the dendritic growth zone, enhancing
snowfall rates. As the midlevel trough develops eastward, heavy
snow, with rates around 1 to 2 inches per hour, will spread eastward
into parts of western and central ME through the morning hours.
