I'm curious about temp difference at similar elevations. This morning we bottomed at 1.8F. We're at 720'. On my way to work, at top of Spiller Hill, 696', temp is -6F. How come? I can't imagine 24' difference in elev would equate to ~8F diff. Meanwhile at 320' (bottom of Spiller) it was -10F, which is expected as it's a shallow boggy area.
