Lighting Up the Night Sky

It was supposed to rain all day but instead we had a beautiful and warm autumn day. But as dusk fell the sky opened up without warning. It started slowly with an electrical burst of lightning coming in from the river. Then came the thunder and the heavy rains. Next was the hail. Here's the only good shot that came out, with the night sky lit up.

UPDATE: This picture was posted on Clarin's Web site tonight. That's hail.
