Two reasons we won’t see much icing.  1.  Screaming SE wind will scour away all low level cold quickly and 2. Latent heat release from heavy rain

It's not a matter of eventually scouring out the ambient cold air, it's the solid ground and surfaces (including concrete and metal) that have been sitting in single digits and low 10s for a long time - i.e., initial liquid would freeze on contact unless the temp warmed up into the 40s for a bit before onset (where onset is supposed to happen late this afternoon and overnight with temps near or below freezing depending on where you live). I'm not expecting any significant "icing" per se but just that there might be some initial coating - although any snow that covers those surfaces first may mitigate it too.

Edit to add - those poor folks in the central and western Carolinas are the ones who are going to have an ice storm extraordinaire.

I agree but I hope that is not all sleet mixing in too

 

For the infamous Morning call and other media outlets. I have provided your media outlet  with tomorrow's headlines since their  headline in this mornings paper is :  "Major winter storm downgraded"   What a bunch of media sensationalists and will come back to bite them hard.

 

Tomorrow's paper headline will say  "A major overperfomer storm stuns Lehigh Valley drivers."  Accidents were abundant as many roads were slippery as the salt and brine could not work very well with the initial temperatures of the surfaces near 20 degrees between 4pm and midnight last night. The snow could not melt quick enough as the late arriving snow continued to play havoc on the  road surface.  Even though it was a only small accumulation of snow and the plows are unable to drop the snow blades until three  inches have fallen, many drivers  refused to stay home and were lured into a false sense of security with their vehicles  resulting in car accidents everywhere. There is your new title and summary Morning Call 

 

If I hear the term" over performer" again, I want to barf.  This is some weather forecasters simplistic term created for simply explaining  away the inaccuracies of their forecasting ability because they just do not know why . Just say I do not know why and I will research and get back to you on what I think went wrong. Thats what real scientists do. They learn from their mistakes. 

 

The media  also uses sensational  terms such as  "double down, " influencer" etc , to hype a story that is failing in truth too. To the Morning Call----Meteorology is not journalism, it is a physical  science.  Get over it.

Welcome back LVWX!

The NAM has ticked up both snow and ice to the NW of I95

It’s the latent heat that will warm all the surfaces extremely fast.  Snow to heavy rain will mean very little icing IMO

if you are not suddenly under a dry slot!

I was hoping to get that of response.  Mesos are coming in with more snow   like it

Bingo. Im sure there will be some icing. But this isn't a major ice storm signal at all. 

I've been at 21F before and pouring rain....not fzra...just rain. Latent heat release didn't allow for ice accretion. Best icing conditions are lighter precip.

I can’t argue with DT’s map for my yard. Setting the bar at 2”, but realize the warm air moves in faster than expected in these set ups.
