Planted an all clover plot 2 years ago. Same situation as you with no rain in weeks but we had at least an inch forecast over the next week. Got the seed down and got less than 1/8" of rain. None of it came up but to my surprise early spring the stuff started sprouting. Actually had a decent year in 2018 and the clover did well. Just checked it this week and with no rain it's browned out and crunchy. I expect most of it will come back when we do finally get some rain and a break from the heat. Mine is 50/50 Durana and Partriot clover. Really makes you appreciate farmers who depend on their crops for a living. Mother nature can be very unforgiving sometimes!
