So Chris and Jacqui are both out after being removed from Storm Center a little over 5 months ago. The fact that they both left at almost the same time tells me that both of them were not being renewed by TWC.
As for the Allen station hits, I'm told that Carl Parker and Todd Borek are two of the OCMs doing those hits. Not sure if any others are involved.
With Chris and Jacqui gone, plus Carl and Todd focusing all efforts on the local hits, plus Jim Cantore and Alex Wilson off today, TWC went with a super bizarre OCM lineup for today's severe weather coverage.
AMHQ Shift 1: Stephanie Abrams, Jordan Steele, and Reynolds Wolf
AMHQ Shift 2: Jen Carfagno and Molly McCollum
TWC Live: Alex Wallace and Felicia Combs
Weather Unfiltered: Chris Bruin and Dr. Rick Knabb
Extra 10pm-2am ET shift: Dr. Greg Postel and Mike Bettes
So apparently the strategy was to move everyone downward from their normal timeslots just to fill out the schedule.
