Petrichor-a pleasant smell that frequently accompanies the first rain after a period of long, dry weather

The land has languished for months amid the annual summer drought
And the cracked clay which bakes beneath the brutal blast of a Texas sun
Awaits the agonizingly slow approach of the autumnal wind and rain
The heat saps the energy from flora and fauna, man, and beast and field
Desiccated air absorbs the last trickle of water from the earth’s skin
Creeks and streams that flowed in the spring are sun bleached limestone
The inflamed soil longs for relief as it sinks exhaustedly into a summer siesta
 
But on this August day there is the earthy smell of petrichor as the wind shifts
Thunder rumbles in the distance as the baked earth prepares to receive
The bounty of the heavens as the clouds open and deposit their liquid life
Cooling off the sunburned skin of the earth and giving the soil a sip
A small foretaste of the feast that will come as the seasons turn
The earth sings and dances in this brief shower which dances on its body
