Though there are rumours that Adobe are working on it...That said, Its a wish not a need....
Was chatting to a friend of mine who is a flash developer and has close contact with adobe. According to his sources Apple want quite a large licence agreement from Adobe for flash - the reason being is that it is a direct competitor to Apple Quicktime.
A good weather app (and seems more accurate than most in my experience) is Meteo Weather Pro. What is nice is if you can graph the expected precipitation by hour over the next few days - I use this to time booking my lessons and have been quite successful.
The above is the pay app tho I believe there is a lite version for free.
