Well, it appears as if the Weather Wizard has yet another relative we knew nothing about! In the last episode of The Flash this month, the Weather Witch will be making her small screen debut and it turns out that she's the daughter of the original (so don't be surprised if XS finds some common ground with her during the course of this adventure).
The CW has also released a description for "O Come, All Ye Faithful" which you can see below:
THANKSGIVING — While Nora (Jessica Parker Kennedy) grapples with unresolved anger over her father’s disappearance in the future, Barry (Grant Gustin) and Team Flash must stop a powerful new meta, Weather Witch (guest star Reina Hardesty), from killing her own father, Weather Wizard (guest star Liam Mcintyre). Sarah Boyd directed the episode written by Jonathan Butler & Gabriel Garza (#507). Original airdate 11/27/2018.
