Low clouds retard surface cooling at night better than clear skies because:

The clouds are better conductors of heat than is the clear night air
The clouds start convection currents between them
The clouds absorb and radiate infrared energy back to earth
The water droplets in the clouds reflect infrared energy back to earth
The formation of the clouds releases latent heat energy

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
Higher than predicted due to mixing
About the same as predicted but will occur earlier in the night
