What weather phenomenon might be less likely to occur in conditions with a low dew point?

Low dew point levels indicate drier air, which can significantly affect the formation of certain weather phenomena. Thunderstorms require a certain degree of moisture in the atmosphere to develop. This moisture helps to fuel the convection process that leads to the rising of air, cloud formation, and ultimately the development of thunderstorms. When the dew point is low, it suggests that the air is less saturated and contains less water vapor, making it harder for storms to form.

Thus, in conditions with a low dew point, the likelihood of thunderstorms occurring is diminished, as the necessary humidity for their development is lacking. Other weather phenomena like fog, rain, or heavy snowfall may still occur under various conditions, but thunderstorms rely specifically on that moisture to ignite the convective processes needed for their formation.
