One trick is to cover the windshield and the part of the hood nearest
the windshield with a tarp of piece of plastic that is stretched over
the windshield and trapped at the sides by the closed doors. Some of
the moisture causing the fog is from snow inhaled by the fresh air
intake which is now melting on the heater core. Any snow that falls
down past the wiper arms and in under the trailing edge of the hood is
going to show up inside the car in vapour form shortly after the
engine warms it.
