Thats a strange one. The only temperature related link I see would be the fluid, but I don't see why that would cause any pull. Try taking it to an independent garage. I wonder if the suspension is on the weak side at all and it is reacting to the road conditions.
Since it is worse after alignment, I question the alignment. A toe in condition can have a similiar symptom to yours.
