Does anyone know how to clear the history data from HW. I keep getting a low of 19 at the same time 2 nights in a row.

Did not see any answer to this so..  go here http://www.heavyweather.info/new_english_us/index.html and look at the software manual.  You will find info under "Features and Display information"  5.10 
name of the file is history.dat .  This manual will tell you how to create a new history file.

Hope this helps.
