If you are planning on using wee_import then you need to delete the offending records from the archive as wee_import adds records to the archive it does not update existing records. If you intend manually changing the rain data using some command line SQL or a GUI app of some description then you just need delete/change the rain field data. This wiki entry <https://github.com/weewx/weewx/wiki/Cleaning-up-old-'bad'-data> covers cleaning up 'bad' data but its techniques can be equally applied to updating incorrect rain data. At the end of the day it probably comes down to how many records you have to update and whether you have the complete suite of observations for the archive records you need to alter. Remember also that your rainRate field may have been calculated based upon your bogus rain data so you may need to alter that as well. If you are running WeeWX 4 one solution may be to set any bogus rainRate entries to null/None and then use the wee_database utility <http://weewx.com/docs/utilities.htm#wee_database_utility> with the --calc-missing option to re-calculate your (now missing) rainRate fields.
A couple of other implied tasks, if you update your archive using something other than wee_import once you have updated your archive data you need to rebuild your daily summaries over the period you updated/modified. The wee_database utility will take care of this. Also, if you are generating any NOAA format reports you will need to delete them all so that WeeWX can rebuild them with the updated data.
