But if I were trying to decide wheather or not to turn on my sprinkler system, I would be more inclined NOT to turn it on (Tuesday) if the rest of the week was 50% for each day (assuming it didn't rain on monday). 50% each day for the rest of the week is a heck of a lot better than 0%. Yet your percentage for the week does not reflect that difference.

Perhaps I shouldn't be asking for a weekly percentage but one week does seem to have a much better chance for rain.

I leave my sprinkler system in the off position and if it has not rained fror the entire week, I turn it on for Wedneday night so it waters on Thursday morning (my night to water). Then I turn it off again.

My rule of thumb for rain is 50-50. It rains or it doesn't.
