I think 1-2" is probably the best call for Friday for the following reasons/factors as I see it:
Total QPF
Intensity of QPF falling
Time of day that it's falling
I just arrived at work - it was 20.1 at home when I left. When I walked out the front door, it sounded like a faucet was running. There is a lot of melting going on at 20 degrees. If temps on Friday are close to 30, snow will struggle to accumulate with light rates. Yards not so much, but streets may remain wet the entire day. To me, Friday seems to be falling squarely in the "nuisance" category for most.
I am really excited for the end of the month into February. Me thinks we're going to have a lot of fun in the coming weeks.
