Heavy rain starting here now, looks juiced upstream. Had around 1.3 inches overnight last night.

Have a big outdoor event up here on Signal Mountain tomorrow evening. Looks like possibility of a shower rolling through around 7 pm. Low overall %.

How likely is it something develops tomorrow between 5 and 8 pm, and if it does, will it move through quickly?

How did things turn out?

Added 1.1 inches of additional rain from midnight through early morning.

Pretty sparse rainfall down here so far. I got 0.46" Sunday morning, but very little since then.

Rained a quarter inch in the morning through noon. The morning forecast underestimated the system. But it had been so dry the rain was soaked up quickly and the event was fine to be held. It was hot and humid until the sun went down and then cooled off nicely.

Today/tonight's rain, which was the highest chance/flood hazard day, is a flop. It didn't rain enough to wet the road under trees here. There may be more upstream but we'll see how heavy it actually is.
