How to ready your barometer: The chrome pointer in the glass should be turned so that it rests directly above the black barometer pointer. The chrome pointer acts as a marker enabling you to remember today’s pressure when you next look at your barometer. You can thus see whether the pressure is rising or falling and how significant a rise or fall in pressure has occurred. A rapid increase in pressure indicates a short period of good weather and a fast decrease indicates storms and strong winds approaching.
A slow, constant increase in pressure indicates a period of settled, dry, sunny weather, whereas a steady decrease indicates persistent bad weather.
If the pressure falls considerably below 1000 millibars, you can expect storms and strong winds.
