This is a long shot, but marginal electrical connections (loose, dirty, oily, etc.) become non-connections when exposed to moisture. Was it cool or damp when your car didn't start? Also, someone recently posted a message that they had knocked a coil wire loose and didn't know it while they were putzing around underhood, resulting in a no-start. I've had the secondary wire come loose from the coil tower, which also caused a no-start condition.
