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

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

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:

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
Higher than predicted due to the release of latent heat
