Fitzroy's Storm Glass - How To Read It
I might as well just cough up my secrets to accurate weather forecasting, since some members might want to know. I don't go by NOAA, The Weather Channel or Accuweather. I use a Fitzroy's Storm Glass - a glass tube filled a water/ethanol mixture and two different salts. The dissolved salts form crystalline structures that change form with the barometric pressure.
How to read:
If the liquid is clear, expect fair weather.
If the liquid is cloudy, expect overcast skies with a chance of rain or snow.
Cloudy with small stars means a storm is near, or snow in winter.
If there are large flakes throughout, expect thick cloudcover with snow in winter.
If there are crystals at the bottom, there will be frost.
If there are crystals at the top, expect high wind gusts.
Although many sources say such a device is inaccurate, I've so far gotten 50% accuracy with the glass alone and 70% when combined with observations. Only time will tell, but right now I'm following it, and it looks like there will be clear skies with frost in the morning in my area.
