ANIMATED COLOR FORECAST ICONS
Animated forecast icons use changing atmospheric pressure to predict
weather conditions for the next 12-hours with 70-75% accuracy.
INTELLIGENT WEATHER FORECAST
This station learns; please allow 7-10 days for barometric calibration. This
will ensure an accurate personal forecast for your location.
The forecast station samples the barometric pressure every twelve
minutes.

average hourly readings.
The icons forecast the weather in terms of getting better or worse and not
necessarily sunny or rainy as each icon indicates.
FORECAST TENDENCY INDICATORS
Working with the forecast icons, the tendency indicators let you know if the
weather is improving, steady or worsening.
