Had this in the Friday snowstorm thread with a mention of it in the title, but since that thread was merged and the title lost, figured a new thread on this threat was worthwhile, as freezing rain is seriously dangerous stuff. The NWS issued advisories for most of the region (all of the counties in blue in the map below) for 7 am to noon Wednesday morning, as per below, due to the chance of a glaze of ice due to freezing rain. While these types of advisories don't verify that often, it's worth being a little extra careful if you're out and about tomorrow morning, given that freezing rain is the most dangerous winter weather we get, usually. There's also a similar advisory to the one below for most of SNJ/DE for 5-9 am tomorrow and one for NYC/NENJ from 4 am to 10 am.
