Your timing is a bit off. Even with the "good" weather we had, the bees are unable to propolize the spacers. Any hive management that involves breaking their propolis seal should be completed by Halloween at the latest. If the hive is well-sheltered from wind, you should be OK, though.
Sometimes a cluster will break during the day and reform into 2 clusters for the night. When the weather is warm enough to break cluster again, they can join up as one. Hopefully, since it sounds like you have good numbers, your girls will be OK through this storm.
