Weather can indicate our internal responses to situations.

If, for instance, there was a storm in our dream our emotions would be stormy, perhaps angry and aggressive.

If we are watching a very blue, unclouded sky, we may be recognizing that we have the ability to keep the situations that we are in under control. We do possess the ability to control internal moods and emotions that may not have been possible in the past. Being aware of the weather would indicate that we need to recognize that we are part of a greater whole rather than just individuals in our own right.
