We have a new device on the wall at the Membership Services Desk in the Musuem & Visitors Center. It's called "Weatherbug", and as you can see by the snapshots below, it gives a lot of information. Every few seconds it rotates from the current weather conditions, to a 3 day forcast, then a view from the roof, and finally live Doppler radar. This is really great for our visitors as well as our Guides, about to go out on a tour.
If you work at the Membership Services Desk; make sure you look at the "weatherbug" each time you arrive. Sometimes it "freezes" on one screen. If you see this; simply turn the switch off on the back of the screen. Then turn it back on; it will re-boot and work fine
