Millersville used to have some good info online, but back on eastern i think either Will or dt had actually made a thread about it which was a huge help.
Its incredible how often one of the smallest counties has such a ridiculous gradient. The difference just driving a couple miles up the palisades or rt 59 is gonna be nuts.
And the cold is north of quebec. Thats why when the storm drags down colder upper atmospheric air, its only gonna do it in the catskills, closer to the warm quebec air.
Even down here some of the side roads were slick. It must have been 50 degree ice though, as we were told the now trustworthy gfs had no below freezing temps from the 10th onward. Weird.
