ANIMATED COLOR FORECAST ICONS
Animated forecast icons use changing atmospheric pressure to predict
weather conditions for the next 12-hours with 70-75% accuracy.
INTELLIGENT WEATHER FORECAST
This station learns; please allow 7-10 days for barometric calibration. This
will ensure an accurate personal forecast for your location.
The forecast station samples the barometric pressure every twelve
minutes.
These samples are averaged hourly and daily then stored in
nonvolatile memory.
The three hour pressure icon change is based off of the last four
average hourly readings.
The icons forecast the weather in terms of getting better or worse and not
necessarily sunny or rainy as each icon indicates.

Model: 308-1425B www.lacrossetechnology.com/support pg. 8
FORECAST TENDENCY INDICATORS
Working with the forecast icons, the tendency indicators let you know if the
weather is improving, steady or worsening.
Rising Pressure
Weather is Expected
to Improve
Steady Pressure
Weather is Expected
to Stay the Same
Falling Pressure
Weather is Expected
to Worsen
24 HOUR PRESSURE HISTORY GRAPH
•The bar chart indicates the air pressure history
trend over the last 24 hours.
•The columns represent the pressure change
(”InHg” or “hPa”) readings at specific times.
•The “0” is equal to the current pressure and
each bar represents how past pressure was
compared
to the current pressure.
•Read the graph from left to right. If the bars are rising, it means that the
weather is getting better due to the increase of air pressure.
•If the bars go down, it means the air pressure has dropped and the
weather is expected to get worse from the present time.
TEMPERATURE ALERTS
