You’ll probably be like me...a quick drop in the evening and then it sorta levels off as the cold drains into the valleys. I’m at 43° on the hill, but the lower els around me are about 3-5° cooler. You’ll have cooler daytime maxes as a trade off. It’ll be even more extreme in winter. If BML hits -30° you could even be around -20° with a bit of a breeze. The old Randolph COOP from the 1940s hit -30° on one of the state’s coldest days on record in Feb 1943. CON and PWM had their all-time records of -37° and -39° respectively with that.
