Weather

• Wind Direction combined with change (Backing, steady, Veering) [NW steady = X]
• Barometric Pressure with a limited number of ranges to select from [20.8 to 28.8 = 8]
• Rate of change of Barometric Pressure [ normal (not changing) = 3]
• The current conditions - This means is it sunny, raining, overcast - This needs some type of cloud sensor - [Overcast  =  4]

I have an older Heathkit Weather Station with LED displays (ID-4001) but when I connected a ribbon cable to the data port it made a very large amount of radio interference just by being connected.  Maybe the later model with an LCD display and RS-232 interface solved that problem.
