Can you cast solid fog with other fog spells?

[Hypersmurf]

... however, tossing a Fireball in the middle of a low-level Fog spell... would that equal the force of a Gust of Wind and dissipate the fog?

Obscuring Mist is specifically burned away by a Fireball; Fog Cloud has no such provision in the spell text.

So right nor PCat prepares a conjuration specialist that can summon quickly and casts a lot of fog spells. Waiting to see him in the story hour.

Sure, wait six months.

My players stay out, please:

Meet Thaddeus Sloat, demonologist and the nicest guy that no one really likes. I was noodling battle tactics for him in case negotiations between he and the party break down. Part of that was "How do you stop people from escaping a cloudkill?" The obvious answer was by following the cloudkill with a quickened solid fog. The fact that this will occur during a time stop makes the whole thing that much more fun.

I think I'll allow this to work, since air penetrates a solid fog just fine. It'll be fun to see how they handle this. . . assuming they pick a fight.
