RMK: Temp has struggled this morning. There's not been a
breath of wind to mix the air. A lot of smoke in the air from coal
and wood fires in the village. It's just hanging in the stagnant air.
Cu hum on the SW horizon. There's also some high Sc and Ci
down there. It's a glorious sunny day, though.
