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.

FORECAST TENDENCY INDICATORS

Working with the forecast icons, the tendency indicators let you know if the weather is improving, steady or worsening.

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.
