We're actually hoping here in Dallas that it will break the hot spell and give us some rain. 20 inches of rain would not be good, but we would all love, say, 6 inches spread out over 3 days.
You might get 6 inches spread out over three hours ... just for starters. As long as the center of circulation stays east of you, DFW should be spared the worst of the rains - but you still could get significant flooding, especially if it drifts in your direction.
I know what you mean...
I find myself feeling a LITTLE teensy bit disappointed in the forecast because we AREN'T forcasted to get much, if any rain....
but then, I feel guilty about thinking that way....
I don't like feeling guilty so I think I will turn on the sprinklers full force this weekend, instead.
