It's in deep South Jersey, but the temperature hit freezing in Millville three weeks before it did so in Philadelphia, and two weeks sooner than Allentown.
I have often wondered about this since My first vehicle with a temp reading was bought.I have been living in Laurel lake since then,actaually constantly since 93. I have noticed enroute to and from work (and I work shift work so this is often around midnight) that the intersection of 555 and Buckshutem Rd (670) is often several degrees colder then a mile or so away in either direction.Also an even colder spot usually is at 555 and Battle Lane intersection a mile south of here.Both are hilltops.I would think Buckshutem Swamp in between would be the cold spot since it is low and a cedar swamp and would be a sink but perhaps the water moderates the temp a bit? I have often thought that trees seem to put out a little heat as well since snow often melts first from their bases.Radiating solar heat from the day? In any case by the time I get to my house in laurel lake central the temp has usually risen one degree from the cold spots but I work in Bridgeton and by the time I get there the temp has usually risen five or six degrees. I would rather be in a cold spot then a hot spot. The cold hurts more the older I get but I still hate sweat in my eyes.If I"m not in a crik I want a sane temp like 80 or below.
