Wantage NJ This post at 740'MSL. Plenty of freezing rain.  Sleet and snow mix began 435P went to zr- at 5P. At least 0.14" liquid since it began. glaze on all surfaces except driveway spotty. Unsuspecting would fall.. it's not the solid ice at 25F zr- but it's slippery with thin film on all trees.  Temp 31.6F.

31.5F with steady light rain in central Dutchess. A very tenuous glaze on elevated surfaces, but water is mostly running off.

Now 32.2F. A few remaining isolated slick patches underfoot, otherwise no problems.

(While I have no delusions that my PWS is sensitive or precise enough to reliably track temperature to tenths of a degree, the jump above 32 did seem to correspond to the end of ice accretion.)

Ice pictures from a nighttime 0.2"+ freezing rain event with estimated radial thickness of 0.12".  Pix at 715AM  This icing followed a max daytime temp of 34-35F and occurred at 31.5 throughout the night  til the 430AM ZL- 32.0.  This in my mind, counters an argument that we need 20s temps for a good freezing rain event. Nighttime I deny that.  Treated surfaces wet but I think we need to be careful about dismissing dangerous icing for pedestrians at night at temps of 31.5F. Was a good advisory throughout inside I95 and maybe I95 itself.  I will stand corrected with any science that says otherwise. These pix I think help my concerns about icing at 31F. off my pulpit for now and will listen to counter arguments. Can redistribute as you wish.

That’s how you run a freezing  rain event IMO, .2” coating, treated surfaces had no issues. It was a beautiful site earlier driving around with just enough ice to make for some gorgeous sights but not enough to case major issues. Now it’s raining under all of the trees as it melts away.
