3.3.3 Weather Forecast
Weather forecast is based on learning the local air pressure over a period
(at least one month) and then making a prediction of the weather for the
day ahead based on the change in air pressure.
There are seven weather conditions: Sunny, Partly Cloudy, Cloudy,
Rainy, Stormy, Snowy and Storm Snowy.
Rain/snow will blink when in a Stormy/Storm Snowy condition. When
the outdoor temperature is below 32°F (0°C) and the weather forecast is
Rainy or Stormy, the display will show the Snowy condition.
