Icy sheen on all snow surfaces

It feels like an abnormal January weather-wise here, but I just looked back at my temperature records for the past four years (January '06 through January so far) and it's not that abnormal. I'm aware that a scant three or four years of records means little, but it's still fun comparing year to year. No averages calculated yet - that'll be next.
In January '06 we had mostly 30s and 40s as our daytime temps, and single digits below zero all the way up to 34 degrees for nighttime temperatures.
In January '07 my outdoor wireless thermometer bottomed out once (-21.9, can't believe it bottoms out at that temperature!) and only five nights were above zero. Daytime temperatures ranged from 11 degrees to above 40.
In January '08 temperatures were very similar to last year, with the thermometer bottoming out twice, and daytime temperatures were in exactly the same range as '07.
This year is wienie compared to the past two Januarys. Thermometer has not come close to bottoming out - the lowest has been -11.1. Our daytime temps have not gone below 20. Personally I'd rather have blistering cold than what we have, though this year is still better than having bare ground showing. Still too cold to ride the bike to work, though.
And as today's blog title says - the thawing and re-freezing we've had nearly daily has made all snow-covered surfaces look as shiny as a bald pate.
