The sun was high in the sky, bright and hot.
The sun was almost hot in a bright blue sky.
Saw the sky, bright and pale all at the same time.
With the sky still bright at game time, the conditions shift.
He thought about that for a moment, looking out the window at the bright sky.
For example a field with a horizon to a bright sky.
Then at last clouds begin to form in that hot, bright sky.
The clouds had moved on and left a clear, bright blue sky behind.
He just stared up through the open door at the bright blue sky.
The open air was cold, the sky gray but bright enough to hurt his eyes.
