Regarding barometric pressure readings:
When you call your local airport or TV station for barometric pressure, please keep one thing in mind....
These readings are all 'corrected' to sea level.
For example, if your TV station says the current barometric pressure is 29.85 inches Hg, they are 'correcting' the pressure to what the TV station would see IF they were actually at sea level in elevation.
Now if your current elevation is let's say, 1000 feet, then you SUBTRACT 1.0 inches Hg from the TV station reading, so your actual barometric pressure would be 28.85 inches Hg, at your current location, assuming you are also close to the TV station. If you happen to be in Denver, then you subtract 5.0 inches Hg from whatever is broadcast on the news in that area, since Denver is at 5000 feet above sea level.
Hope this helps, Jim.
