I'm sure some will disagree and say temps before don't matter, but IMO the warmish temps we had(I had) the few days prior to this storm affected accums. If it had been 30s leading up to this then I think roads/grass would have caved sooner. But I got to 49F before the squall front Sunday. To me and my experience, the ground and pavement was toasty. Not a complaint but more a observation that the snow could have been better for some if you take prior conditions before this storm into account.
29F current so things will stay icy for a while.
