To expand slightly on Tom's response to the second half of your query, wee_import is designed to import *complete archive records* (or, at least, as complete as the source device produces) from an external source into the weewx database. It is not intended to update selected fields *in existing records*, which is what you want to do, nor can it be used to do so. Depending on your comfort with SQL and/or Python programming, you will need either to use the sqlite3 app directly to update the records or follow one of his suggested strategies.
