Monday sounds plenty cool, I have higher confidence in that than in rainfall, but I won't turn any down! I did water the tree canopy, I was able to get it up about 35 ft. which misses the highest part, but got a good bit of it along with some wisteria and honeysuckle, which are both starting to bloom as well.
I know plant life gets its water from the roots, but I'm sure you've noticed in the spring, how after an extended warm dry spell, an overnite rain makes things pop.
