"Canada Day TCUs"

A towering cumulus (TCU) was laying down an isolated shower on the American shore. Not a drop fell during Canada Day Celebrations on the north shore of the St Lawrence River. The weather and clouds were shaped by southwesterly winds down the St Lawrence under a cool and unstable upper cold low situation. The prediction of the bands of convective showers rotating around the cold low during a blocking situation is a very challenging forecast.
I didn’t have any cerulean blue so I made do. Some sailboats cruised by so I put them in the painting.
