From Deacon Severo
and Kenneth Bednarz:

       Easter Sunday morning around 8:00 am, the western part of the sky was overcast with gray clouds, and this bright, white cloud stood out in the gray background with a delicate sliver of a rainbow descending down over the church. There were no other such clouds anywhere. 
     It was an unusual, startling, and beautiful sight that this bright white cloud would be present and seem to hover over St. John the Baptist Church on Easter Sunday.
