Warning - Check date displayed to ensure currency - some stations only produce data intermittently.
Note: midnight sounding might be labelled 2300 the previous day
Once chart appears and you have

on bottom line at expected temperature eg T:26 (79F) 1016 mb and then click
or right click and enter Td (Dewpoint Temp), T (expected ground temp) and P
