How do we get freezing rain at 33?  And what's the highest temp you can have freezing rain at?

 

32F

The air temp could he a couple degrees warmer but the surface must be below freezing.

Thanks that must be it- it was below freezing for several hours last night.

I thought it had something to do with the dew point lol, that the surface cools down to the dew point when precip is falling!

Maybe it cools down to the wet bulb temp instead?

Not sure why I can’t post photos here. Winter wonderland up here. Gorgeous. 33.3

I am close to that bright band on the radar. Just enough of a warm tongue aloft so I am sleet.

Hi everyone,  Wantage 8 s High Point NJ had to  be offline for 4 hours.  Here's what has transpired in Wantage NJ 4sw. ZRW-- 806AM-810AM, ZL- around930AM-10AM, then ZR- around 10A-1030A with freezing on windshield edges and blades despite heaters  Then. 0.4" snow sleet accumulation as of 150PM with 1 hour of all snow 1230-130PM. Now all sleet. 22.8F will check glaze later but we definitely have glaze here. No wind speed due to glaze but its blowing a bit.  Thanks for participating and all the mPINGS.  Helpful!  Think the operational HRRR had a nice call hours in advance on the precip change to snow for a time here in ne PA/nw NJ. 

Going to be a LONG event with so many interesting aspects. Cheers!

Looks like the models were (for the most part) correct.

 

Yeah, this was the easy part of the forecast.

Models were underdone on the snow up here, solid coating and right around freezing. Sleet pounding on the windows right now

My answer: WET bulb aob 32F, and/or ground frozen. The latter I dont know the answer but if the ground is frozen and its night...suspect glaze on frozen pavement, even above 32F air temp, but not likely on wires/branches.
