The MesoWest Fire Weather 24-hour Trend Monitor displays 24-hour trends in observations for stations within the selected region. This interface is often utilized for fire weather purposes to view trends in temperature, moisture, and wind.
The user can change multiple settings to display data, these settings are...
"X"-h Summary: The user can select how many hours of observations to compute 24-hour trends for. By default observations from the most recent 2 hours are shown and used in 24-hour trend calculations.
