Note that, according to the NWS, there was a "100%" probability of rain by 8AM.
It's almost 11 AM. While the clouds are moving in, it's still sunny and I can see plenty of blue sky. Not a drop of rain yet (though it's coming.)
But the NWS says it's supposed to have been raining for THREE HOURS at least.
And they can tell us what the climate will be in 100 years!
UPDATE: 1:10PM, it's finally starting to rain.
