Jim is pretty much the "face" of The Weather Channel, so I HIGHLY doubt they will let him go. 
As for Stephanie, heck, is she even around at TWC anymore or on assigment somewhere else? Who does WUWA now? I never watch it (nor will I) to find out.
But it is sad that these "classic" OCMs are being laid off. I'm just interested to know WHO TWC likes and WHY they like them. For example, why are Jen and Adam the ones hosting the Summer Beach Party? I like them both...I think they would do a great job, but WHY are they the ones hosting. 
If you need any further evidence of Cantore being their "poster boy", watch the new ads they have with him. They make him look like a football player entering the arena. Instead, he's walking into a Cat. 5 hurricane
Cantore, Abrams, Bettes, and Roker are probably signed for life with that channel, the rest are probably going to be shown the door before long. Hate to say it, but I bet Viv Brown is the next one to hit the deck.
