I mowed for the 10th time yesterday. Still growing well in most areas.
I'm at work and haven't seen any rain - completely possible that there's been what you've described. I asked my wife if she saw rain at home and her response was "huh?"
What happened to the forecast? Last night it looked certain that today and tomorrow were washouts.
Edit: Actually it doesn't look that far off for today after all. Maybe a little less areal coverage.
