Good news bad news coming. Good news is higher pwats, greater low level moisture, dews in the 70-75 range, and the ridge center moving away will lead to at least some storms each day maybe starting as early as late Friday but more likely late Saturday. Bad news is with the ridge retrograding SW all of the high 850s are going to move right into the area so highs are more likely 95-100 with HIs well into the 100s.
I am really hopeful that as we get out towards the end of the month we avoid centering another ridge overhead like the 12z gfs and getting another front through like the cmc. If we split those 2 with a deep WNW flow aloft and a bermuda ridge we still stay hot but it's a much wetter heat wave
