Dec 20 17:12:39 nuova smartd[22451]: Device: /dev/sda [SAT], SMART
Usage Attribute: 190 Airflow_Temperature_Cel changed from 67 to 68

Is it normal for SMART to update the attributes as the drives are
being used? (I've never had SMART installed before, so this is all
very new to me).

If your drives run at 68 degrees Celsius, you should emergency-cut the power
ASAP and perhaps reach for the nearest fire extinguisher.

Agreed. ;) That's why I posted those messages -- I'm unsure why it
would change those values.

Here's what smartctl shows for all of the drives:

~ # for i in a b c d ; do smartctl -a /dev/sd$i | grep Temperature ;
done

Those values seem appropriate, particularly since the "max" is 37 (as
defined by the drive manufacturer?).
