I was thinking about that yesterday, how much does a "higher" launching pad really influence what the high temperatures will be? I would think the correlation has to be extremely low.
I would figure a higher launching pad just means you're already fairly well-mixed. Meanwhile, if you're radiating well your lows will drop. But, if you're achieving full mixing and say expecting a high of 95 or whatever...who cares if you start at 71 vs 66...all that's going to happen is you're going to see a much larger jump in the morning hours from the 66 versus the 71 once mixing gets going. (I hope this made sense haha).
