August 19: Eclipse Cloud Prediction from the Washington Post

It is looking iffy in the hinterland right now, but don’t give up all hope just yet. The Washington Post says their overall forecast confidence is “medium” two days ahead of the big event. The confidence level will go up as we get closer to the eclipse. They are posting a new prediction every day. If you have a flexible schedule you can still change your eclipse travel plans to head to a less cloudy place. That is my plan. This will be my last update of the Washington Post eclipse forecast.

If you are tracking the weather at several possible eclipse locations, read this article.
