Residents in the Adirondacks were treated to a double rainbow just before sunset on Thursday Evening.. The Rainbow was bright and quite colorful. The sun had clear skies and a clear shot to the showers to the east and it was definitely raining.. The rainbow was bright and clear with more colors than many have seen in a lifetime and across the entire spectrum. (We mentioned in our tweet that the picture probably doesn’t do it justice) The moon was only just covered by a cloud under the rainbow..
