Ultimate Wilderness contains a fairly comprehensive (although not very accurate compared to Earth) weather system, including rules for multi-day forecasts. I've made a generator using those rules here.
Thanks everyone for the positive feedback by email. I have found the time recently to work out more of the bugs, improve formatting slighting, include support for generating 31 days, and (most significantly) include support for the metric system!
Thanks so much for all the support and encouragement. If you have any further suggestions for improvements, do let me know.
