..no thunderstorm areas forecast... 


... 
thunderstorms are not expected across the Continental United States.

Weak convection may develop along southward-surging Arctic frontal zone 
across portions of eastern Idaho into western Wyoming. However...buoyancy and depth 
of convection should prove inadequate for lightning. 
Elsewhere...mostly dry and stable conditions should prevail.

Areas affected...southeastern and eastern ME 


Concerning...heavy snow 


Valid 270358z - 270800z 


Summary...snowfall rates locally exceeding 1" to 1.5" per hour will 
continue over the next few hours...but should continue gradually 
diminishing overall. 


Discussion...latest radar loop shows steadier/widespread snow 
gradually shifting northeastward out of ME at this time...with more banded -- but 
still locally heavy -- snow lingering over much of eastern New York and New 
England. As the upper vorticity maximum now crossing southern New England 
continues moving northeastward -- thus yielding a decrease in qg ascent 
across the ME vicinity...expect overall coverage and intensity of 
snowfall to trend downward with time into the overnight hours. 
However...snowfall rates locally in excess of 1" to 1.5" per hour 
will continue locally for the next few hours within heavier bands 
across portions of northern and eastern ME -- near and north of the track of the 
middle-level system.
