Lol, yea if only you could bank up that extra water as a reserve in the soil. Honestly 1.5" or 7" in a week will make no difference for the lawn in a week if its 85-90 and sunny, it will start browning probably within 7-8 days again. 7" is good for lakes and streams and Oak trees, but lawns don't need that much.
Looks humid and stormy though next week.
