Congrats on the rain! I had the same problem here in July (about a month of almost no rain with 3 days well into the 100s and almost every other day into the 90s). Now this month, I cant get rid of the rain. If Hurricane Irlene follows the path that is currently forecasted, not only will it bring some wind damage here in NYC, but it will also probably bring the monthly rain total in my yard to around 20 inches!
But even with this huge surplus of rain, I still notice a nice explosion of growth when the sun comes back out!
