drfranklin,
Depending upon what GPS gizmo in one's hand, we are at 4890 - 4920 feet.
A couple neighbors have the semi-pro consumer weather stations, but all I have is a simple rain gauge and a indoor/outdoor thermo, but I have checked both readings with my old Eastman Kodak technical thermometer; my set is close to nutz on. None of my neighbors are hooked into providing data to any commercial site. A neighbor down the mtn, around Laurel Ridge CC, is hooked into a rain/temp reporting deal through NC, but he lives at ~3200 feet, so he is usually much warmer, and his rainfall is often less than ours, fwiw.
A webcam site that is in our area, 5,000 ft and only a few miles away as the crow flies, with a cam view slightly more narrow than ours and looking more east, but the temps and data are very similar, over the years:
NPS: Explore Nature » Air Resources » Air Quality Webcams » Great Smoky Mountains NP, Purchase Knob Camera
From fading memory, about 40 ish in the overnight/early morning since Sept 2001, but we have dipped below 40 during summer storms, esp when the hail is pouring down on us. When the usual packs of out of state/out of area friends come by to stay with us, most are surprised at the common temps up 'here'. We have a closet full of spare sweat shirts, sweaters and windbreakers for complimentary use by our company.
Our main room and deck area do face east/south east, so solar gain is often quick and comforting on cooler/cold days; on cloud covered days or fogged in days, not so much.
Winters can be brutal up here, at times; we got the 5 Year Award for being here full time, but that was then.
Last winter, our good neighbors showed their outside temp readouts at -10 deg F for a few days with a 'high' of -1 or so during a couple days. And, they were housebound for a week plus, which we remember those kinds of days here in winter, too. Plowing the roads is done by a hired gun, but some of the north facing roads are tough even for his powerful yard rat 4WD truck, with chains and plow.
