It all plays into it, but I still disagree about the 850s. 18-20C is impressive any time of year and results in mid 90s in SNE as well. 18-20C doesn't grow on trees up there. Heck the 12z Euro had 21C around Sherbrooke this afternoon.
idk...19-20C is pretty impressive up there. Seems pretty supportive of the widespread 90-95F temps.
Kinda funny to see 20C 850s up in NNE and only 12C over NJ.
