6.5.1 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.

6.5.2 Wireless Signal Quality Icon
The wireless signal strength displays reception quality. If no signal is lost, the signal strength indicator will display 5
bars. If the signal is lost once, four bars will be displayed, as shown in Figure . A bar is removed for each consecutive
loss of signal.

6.5.3 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 Weather Channel) have many tools at their disposal to
predict weather conditions, including weather radar, weather models, and detailed mapping of ground conditions.
6.5.4 Lightning Icon
The lightning icon appears when then Dew Point exceeds 70 ºF, which signifies temperature and humidity
conditions may be possible for lightning storms to form in the area.
