The original question was a very good one.
Can I please ask for clarification from m.r.a.z.23; you said it was a TTF and that it had intermittent endorsement of VCTS.
As the TTF is made up of two elements; the METAR and the trend, was the VCTS on the METAR part or the trend part?
I have never seen a forecast of VCTS, but I have seen many observations (METARs) of VCTS.
I doubt that a forecast would have that in it because it's too non-specific.
