Not melting that fast north of the city, looks pretty similar to where it was Tuesday outside the most sun exposed surfaces. Even still some ice/snow on road and drive way.
Of course once temps get into the mid/upper 40’s next two days that will change.
Past storms like Jan 2016/Feb 2006 melted out much faster. Biggest factor is temps not sun angle.
Even for Boxing Day a pretty good chunk was taken out quickly as temps got into the upper 40’s+ a few days after the storm. Then the hammer really started dropping in the form of more storms and very cold temps in early Jan.
