I grafted about 20 queens on Thursday, 5/8 and according to the queen rearing calendar I need to transfer the individual cells to nucs on Saturday, 5/10, and the queens should emerge on Tuesday, 5/20. The weather has been very cool this week, like 15 degrees cooler than normal. Does the cooler temperature delay or inhibit queen development? Thanks for anyone's sage advice.

Long as there are enough bees in there they will keep the temperature right were it should be. If the weather is bad & no foraging is possible a little sugar syrup fed to them keeps them stimulated & happy to raise good well fed cells.

Temperature could affect them by a day or so.
If you grafted on 5/8 you dont want to put them in the nucs on 5/10. They wont even be fully capped yet. You should put them in on 5/18

Good luck.
I'm exactly in the same schedule as you. This afternoon - make the mating nucs and tomorrow give them the cells. The weather is not very appropriate for bee manipulations: after the rain stopped I got high speed wind and cold. It wont be so pleasant.
