4.8.2 Weather Forecasting
The five weather icons are Sunny, Partly Cloudy, Cloudy, Rainy and Stormy.
The forecast icon is based on the rate of change of barometric pressure. Please allow at least one
month for the weather station to learn the barometric pressure over time.

4.8.3 Weather Forecasting Description and Limitations
In general, if the rate of change of pressure increases, the weather is generally improving (sunny to
partly cloudy). If the rate of change of pressure decreases, the weather is generally degrading
(cloudy, rainy or stormy). If the rate of change is relatively steady, it will read partly cloudy.
The reason the current conditions do not match the forecast icon is because the forecast is a
prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a
good idea to consult the National Weather Service for more accurate weather forecasts. In some
locations, this prediction may be less or more accurate. However, it is still an interesting educational
tool for learning why the weather changes.
The National Weather Service (and other weather services such as Accuweather and The Weather
Channel) have many tools at their disposal to predict weather conditions, including weather radar,
weather models, and detailed mapping of ground conditions.
