ICON depicts any precipitation falling with any layer of the atmosphere above freezing as rain, correct?

I believe that's true.  If it's not showing snow, it will depict the precip as rain even if it's sleet/ice.  Not sure if that's the algorithm used or if it doesn't distinguish freezing vs. frozen.

Whatever it's worth (yeah not much perhaps!!), the Icon shows "rain" at 105 around the DC metro but looking at its surface temperature it is below freezing DC and north.  So sleet/ice then?  Similarly at 108.  Here's the 2-m temps at 105:

ICON seems to run super cold in storms. I remember last year, it had 17 degrees and rain or something in a FEb storm

As far as I know, the ICON reads every non-snow precip type as "rain". 

So what they depict as "rain" may very well be a wintry mix.

Could be, I'm not familiar with the ICON's tendencies overall.  But I also know those depictions on TT at least, it doesn't distinguish between snow and anything else.  So many times when it shows rain it could well be ice depending on the surface temps.
