I would suggest you have a proper plan on how to cope with a read only rpi - or maybe even just run the rpi and weewx in a standard configuration until you know how everything works - especially if you do not have a RTC installed. Also make sure that you are not running the latest NTP software which I believe has some form of buffering similar to fake hwclock - but not quite as bad!! I saw someone mention this in a recent thread in this forum.
