The upcoming pattern isn't going to feature sustained heat/humidity. It is going to be an active patterns with fronts and shortwaves. With this, we'll get some hot/humid days mixed in, especially ahead of systems followed by a return to more seasonal conditions.
Our perspectives of what should be happening are way out of whack. This looks like a much more typical stretch of weather for this time of year. We shouldn't be building in extended heat/humidity regimes early or mid-June. We should still be active with fronts and varying between a few days of heat/humidity followed by several days of seasonal weather. Building in extended heat/humidity shouldn't really happen until you move into and through July.
