How long for rain to melt snow and ice?

    I am here in the northwest, where we are going to have a huge snow storm, and I'm wondering:

    How long would it take rain, falling at 0.3 inches per hour, to melt 6 inches of snow, and 1 inch of ice underneath said snow?

    There are a million factors that make this impossible to figure.

    Temperature, sunlight, area, substrate, wind...

    Add in the temperature of the roads and surfaces that the rain might fall on. Once our paved driveway falls reliably below freezing, we have no reasonable expectation that a warmer rain can possibly melt off the snow and ice. If anything, the snow will generally condense and densify, and the underlying ice will be all-but-impossible to dislodge.
