Re: queens coming with bad weather until Friday.
Go ahead and do a Queen excluder if you wish. As Vance advised, put the screen face down in center of queen excluder, as center of a big hive is warmest.
This would be overkill for a few days, if cages have live attendants. Just mist the cage screen on the non candy end three times a day-early morning, noon, and late evening. The attendants will make some syrup and feed the queen. Don’t mist the candy end as water dissolves the candy and inside of cage gets to be too sticky.
Zone 3b. If you always do what you always did, you'll always get what you always got!
