You do realize that NOAA/NWS has always had geographic differences for criteria of advisories, watches and warnings of all different types? There are differing criteria for cold temperatures, frost/freeze, snow, etc as well. Here you are 100% correct in stating facts about temps in those other locations yet 100% wrong in your assessment as to why they did not receive advisories and we did...
EDIT: Looks like several others have also brought up this point.
