Step 7: Weather Tendency

Press the Tendency section (see graphic). The bottom section of the screen will show when the weather condition corresponds to the currently displayed symbol, along with the time and date.

The symbols are Sunny, Fair (Cloudy with Sunny intervals), or Rainy. The Up and Down arrow next to the symbol indicates weather tendency. Advanced storm warning is displayed by the Rainy symbol with a flashing down arrow.
