Louisiana weather per HeroHog, Reply #14:
Interesting graphs.
But:
Pressure 29.99 in
Visibility 10 miles
Clouds Clear
...
Etc.
Anyone know why they no longer state whether the barometer is rising, falling, or steady?
I've noticed that for the past couple of years.
It used to be that rising, falling, or steady was a primary predictor of short-term conditions.
A given value of pressure is not a predictive number and basically useless unless I'm setting an altimeter. It's a descriptive number, but not a predictive one unless you know what the pressure was, say, an hour ago.
What gives?
