An important reason for the large daily temperature range over deserts is:

Dry air is a very poor heat conductor
Free convection cells are unable to form above the hot desert ground
The ozone content of desert air is very low
The light-colored sand radiates heat very rapidly at night
There is little water vapor in the air to absorb and re-radiate infrared radiation

Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32oF. Suddenly the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be:

Higher than predicted due to the release of latent heat
Much lower than predicted due to radiational cooling
About the same as predicted but will occur earlier in the night
Higher than predicted due to mixing
