Driven from the Sky

Driven from the sky,the midsummer sun
Under the deep stratus line  
Belying the date of 
Midsummer Equinox- 
The longest day and a latent heat
As the jet- stream dips 
A cooling air and veil of rain
Descends
And a sombre view prevails
To tune of the steady drip and 
Splashes on the pond
And sodden grass
The die is cast
For the summer lot.
