As far as what kind of precipitation will fall from this storm..a wintry mix is expected. The farther north and west you are from DC the more likely the precipitation will be of the frozen variety, the farther south and east you are the more likely it will be more liquid. AND before the storm moves out, it could change to all snow across the region. BTWcomputer models continue to show big differences in solutions run to run and from day to day. Stay tuned!
