Humidity hugging you and Distant thunder

Distant Thunder, 9 by 12 watercolor, 140# Fabriano Artistico

Summer on the southern Great Plains doesn't look at calendars. 
Today the humidity and temperature  soared, almost sticky, certainly sweaty, weather with bright sunshine. And in the afternoon, the clouds started building, and afar off you could hear the rumbling of thunder as the horizons turned hazy, and gray blotched the blue skies.
You  feel the humidity hugging you, the sense of summer sourrounding you closely. Watercolor is akin to that moisture. It leads to trying to paint that feeling of distant thunder, of dripping atmosphere.
