Multiple choice

The difference in air temp and dew point were 5oC.  An hour later the difference was 12o C. 

  1. RH increasing, chance of precipitation decreasing

  2. RH increasing, chance of precipitation decreasing

  3. RH decreasing, chance of precipitation increasing

  4. RH decreasing, chance of precipitation decreasing

D Correct answer
Explanation

As the difference between the air temperature and the dew point increases, the air becomes drier and further from saturation. This causes the relative humidity (RH) to decrease. Consequently, with less moisture saturation in the air, the chance of precipitation also decreases.
