TNE Posted February 8, 2012 Share Posted February 8, 2012 The highest snowfall produced by an arctic front by itself? Not including lake effect areas. Based from my experience: The best impact from an arctic front would be in the form of strong convection/hail and not snow in areas away from Lake Effect. Thunderstorms will develop with steep lapse rates present, a strong pressure drop occurring ahead of the arctic front, and some WARMER/MOIST AIR at the surface. To have meaningful QPF in areas away from Lake Effect, you will need warm/moist air. Warm/moist air is a bad sign for snow as it occurs over land and at the surface. If an arctic front and upper level low is enhanced by an intensifying lower level low pressure moving east, thunderstorms would occur (especially near the coast). Early January 26th 2006 areas near Philadelphia reported convection capable of producing 1" hail. Areas all over reported convective cells having tops reaching 25000 FEET. There was lightning, some rain, AND pea to golf ball sized hail around MIDNIGHT. Skies remained mostly clear before midnight and the storms exploded in Eastern PA. It was a pretty exciting night.
