a shallow freezing layer exists at low levels, freezing rain, or
is the type of temperature structure that is
necessary for an ice storm
at low levels on will experience freezing rain
higher levels, it will be rain
during the ice storm of '98, LSC was high enough

VT, however, was low enough (el=300') to be in
the freezing rain
