QUITE an amazing number of detailed responses, so thanks.

I found that clicking on the clock in the UI while using the "Rain Accumulation" button, it states as you said, 'a forecast of what the rain accumulatION will be for the next 12, 24, etc. hours/days', (and NOT the rain "accumulatED").

However, when just clicking on the clock while using the more common "Rain, Thunder" button, it says that it will show at least some history: "Rain/snow accumulation in the last 3 hours." Of course, it is only updated every 12 hours at around 4:30 PM, in the middle of our most likely rain period, so it isn't extremely helpful. But, it was showing me some of what I wanted yesterday at that time, right after most of the rain was over.

It seems that if ECWMF has that past history, it is possible that they could make it available for the past 12 hours, instead of just 3 hours, and then present the last 12 or 24 hours of rainfall. That would accomplish most of what I'd be looking for -- a rough estimate of past rainfall.

I have been using a PWS that is about a mile from me from WU, which does an OK estimate. And I agree that I really should put out a gauge, but correct placement away from walls is difficult but vital.

I'm thinking it would be cool to put an unobtrusive gauge on one the side of my mailbox, which is about as is isolated away from obstructions as you can get. Then just check/dump it when getting the mail.

Rain ACCUMULATION for at least the past DAY.
This is one huge requirement that only seems like "history", and that is just trying to discover how much rain I got, even for the past few hours. We just had a huge front move through, and I had spread fertilizer out, and need to know if I should or should not add more water. I don't know how to figure that out, if that data is even available, easily. But, accumulated rain or snow matters more than what the wind was, even an hour ago. Our forecast was for ~.75" - 1.0". Now that the front just passed, the only choice is to see what the NEXT 12 hours are. Even though it is past us, the accum. button seems to show some of the past and is showing .5", which seems likely accurate. Even if that is not showing the past, it would be great to say what that accum. button is, or is not.

-- Other than that, you guys have the best UI I've ever seen! It is simply amazing. Everyone has to eat though, and you've got to be fed by someone. Seems to me this project is no different. Donations might work as well. Take a look at the best (IMO) internet radio station, funded purely by donations at RadioParadise.com -- So it CAN be done, and very profitably if you are good enough. And, I think you are. You had the absolute best tools for understanding the past huge Florida hurricanes, and I used it extensively.
