24 Hour Pressure History Graph/Tendency Arrows
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.
