For sensible weather impacts to the public if areas get 8-12” vs 15-20” it won’t matter to most, it will have similar impact, especially with most of this falling at night. I’m on north shore of Nassau on Long Island and schools are already cancelled for tomorrow. Would be the case if 8” or 18” fall. The high or low busts will determine if Tuesday school is cancelled. Will be a nice storm for most. Would just enjoy. .
