for the city its pretty blah, it may be more of snow that never stick or rain/snow mix.. hr 33 the freezing level at phl is around 937mb or 2100 feet up, so that screams more rain.

For places like dyl ptw, ukt...its snow that flips prob as its ending...hr 36 has ptw and dyl still below with the freeze level around 400-500 ft which is snow. by hr 39 the precip is done...so they are majority frozen

Thanks - Sounds like fall line N+W. Far northern and western suburbs for best shot.

So I suppose ABE and north and west would be all frozen?

GFS looks like it may snow, surface is torched but I see no reason why flakes won't fly, maybe accumulation on grass?

the freezing level per gfs at phl at hr 36 is 1300 ft, rain/snow mix..surface looks like mid 30s...once to my work in wayne on northwest they are solidly snow.

wow 18z NAM looks great for a festivus white miracle

2-3"?

The BUKFIT data should be in in about 15 minutes and I'll check precip type then. 850's are cold enough north of the city for most of the event but 925's and 2 m are warm, so there might be some melting.

its actually worse...u flip just after hr 33 and even before that you are very wet snow...the freezing layer is like 2500 ft up

if the NAM profiles are correct i know often it's warm in that regard, going to find out soon enough

what is total qpf?
