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.
