It's unofficial because Boyden was exaggerating again. Mrs. Boyden said it was actually more like 2.17".

You're welcome - as I spent most of the day yesterday lugging the hose and sprinkler all over my yard just yesterday...
This is kind of random, but where I am the weather forecast for Wednesday Sept 20 (tomorrow) was for a 100% chance of rain earlier.
They just updated the forecast to be 70%.
How can it be 100% at one time and lowered later? If the forecast is for 100% it logically shouldn’t be able to be lowered to less than that later on. Or am I thinking about it incorrectly?
Sorry, just being a little salty because I was really hoping for the rain.

At the time you looked at it the chance was 100%. Time went by, new data came in and it was updated, simple as that.
Right. But then no one should ever forecast 100% because that implies certainty when clearly it’s not certain. Say 99% even, but not 100%
Mostly just being a pain. I know forecasts go in increments of 10%.
And you may need to keep doing this weekly until the ground starts to freeze. Next Spring, barring a crazy wet fall/winter, there will be many brown-out landscape pines, young deciduous saplings, and vulnerable shrubs.
Given mother nature's sick sense of humor, a wet fall wouldn't surprise me just to piss off the farmers trying to harvest.
I don’t know of any meteorologist that would put 100% more than 12-24 hours out and even then it has to be a slam dunk for this very reason. Thus, I would question your source of information and imagine it has no human input to it.
the percentage is telling the area of the forecast that will at least get a measurable amount of .01 inches of rain. All that means was the whole area forecasted was going to see rain but now that means only 70% of the area will see rain.
^Truth. Good advice for peeps to soak their evergreens in, a good soaking and not just surface watering. I'll probably do my white pines and the yews a couple more times.
It was the NOAA site on Monday. Zip code 33928 if interested. I think NOAA meteorologists do a manual grid system right?
So grid A1 they look and say 70% chance. B2 80% chance etc.
Anyway it’s updated to 80% this morning. I’m here a couple more days until heading back to the totally different climate of the Intermountain West.
