Many have awaken to see morning dew in various places; on the grass, on your car and on other objects. Dew is formed as the surface temperatures of objects cool overnight. As the surface of these objects cool to the saturation point of the air, moisture will condense.

When the air can not evaporate at the rate of condensation anymore, we are left with dew droplets. Hoar frost is formed from a similar process as morning dew, HOWEVER, it forms when the air particles go directly from a water vapor state to ice crystals.

As overnight temperatures plunge and surface temperatures cool below the freezing point of water (32°), the air rapidly changes into ice crystals on nearby surfaces.
