Dry thunderstorm
Encyclopedia
A dry thunderstorm is a thunderstorm that produces thunder and lightning, but most or all of its precipitation evaporates before reaching the ground.

 or places where atmospheric water vapor
Water vapor
Water vapor or water vapour , also aqueous vapor, is the gas phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Under typical atmospheric conditions, water vapor is continuously...

 is low. Because dry air tends to absorb liquid water, causing it to change phase into vapor, it is absorbed before reaching the ground. They are common during the summer months across much of western North America.

Dust storms

Strong winds often develop around dry thunderstorms as the evaporating precipitation causes excessive cooling of the air beneath the storm. This cool air then descends rapidly and fans out upon impacting the ground, an event often described as a dry microburst
Microburst
A microburst is a very localized column of sinking air, producing damaging divergent and straight-line winds at the surface that are similar to, but distinguishable from, tornadoes, which generally have convergent damage. There are two types of microbursts: wet microbursts and dry microbursts...

. As the gusty winds expand outward from the storm, dry soil and sand are often picked up by the strong winds, creating dust and sand storms known as haboob
Haboob
A haboob is a type of intense duststorm carried on an atmospheric gravity current. Haboobs are regularly observed in arid regions throughout the world. They have been observed in the Sahara desert , as well as across the Arabian Peninsula, throughout Kuwait, and in the most arid regions of Iraq...

Fires

In areas where trees or other vegetation are present, the lightning will cause the trees to catch fire and there is little or no rain to stop the fire. Storm winds fan the fire, causing it to spread more quickly.
