Hi coupe pete,
Welcome to the forum, and thank you for your words about the WeatherDuino project.
I think that is hard to say what is the maximum range for having a reliable link, there are many factors which can affect the signal. It's better not expect 200 to 300 meters, under very good conditions (line of sight, no concrete walls between, and zones without to much electrical noise) the range can even be greater, however its better not count on it.
There are 433Mhz amplifiers that could be attached directly to the RF output of the transmitter, some are quite powerfull, up to 500mW, but using them may not be legal.
