The ground temperature was 29 * F At 6:15 PM MDT. A thermal image of the partly cloudy skies indicates the cirrus clouds have a temperature of -22 *F.

Assuming a dry adiobatic lapse rate of 5.4 *F per 1,000 feet calculates the clouds are at height of 9,400 feet.

The BOI METAR reports clear skies below 12,000 feet.
