I'd go for the visitor ctr, near the main gate. We had access to the base in 2007, but were escorted to thf base hotel and we were N O T allowed to photograph anything, including Gateguards. But that was back then...
Any luck with jax's PAO?
weather wise, i looked at 2 sites, wetter.de and wunderground.com.
look at those 2 and for both days, and you still won't know the weather for those days...
