Was a nice start to this week, cooling off some on Wednesday with chance of some rain in morning. Then the bottom falls out this weekend, with slight warming again after that.
Looks like meaningful rain hard to come by in the next week. We are staying on the dry side, with only about 1/3 of average last week, and probably less than that this week.
