Was it lightning ?

The light flickers behind my closed lids 
It’s hard to know if it’s lightning 
So used we are to recrudescences of screens 
At the beginning of the day
Should I check the phone
(www.realtimelightning.org)?
But the air is thick and intense 
And the soughing rush of the trees
Signals air whipped up under the heavy cloud
And the sky a thunder black 
With an ominous feel 
As the rain drops 
Splash 
With poignancy
Meeting the slate with a defined creak
One by one, so very slowly
Deliberately
And the cows in the field are sitting down.
