Note 1: Color coding. Green headings indicate blocks the Weather Observer must complete. The remainder are calculated/ completed by MS Excel.
Note 2: Duration should be fractions of an hour.
Note 3: To facilitate MS Excel, the order of entry for Max Wind and Max Gust is changed from conventional. The order is: Spd, Dir, and Time.

13. Palmer summary
Since October 2015 data for the synoptic messages are coming from the new PAWS system.
The station height has not yet been updated in the WMO flatfile list where it is still listed as 8m.
Palmer pressure data are getting rejected by AMPS.
The synoptic messages being sent out have the same pressure for station and sea level.
