Surface charts 2

Here is an example of a 24 hr surface forecast chart.
On this chart we can see the isobar lines, warm and cold fronts, the central pressure millibar values of synoptic scale lows and highs and their position in 24 hours.
The 24 hour forecast position for lows are identified with vector arrows and an X, and for highs with vector arrows and an X with a circle around them.
Adjacent to the forecast positions you can find the 2 digit pressure in millibars, which in this case is 29, which means 1029 millibars.
